Co-Codamol 8/500mg 100 tablets combine paracetamol 500mg and codeine phosphate 8mg for the short-term relief of moderate pain in adults and young people aged 12 and over.
Each pack contains 100 tablets, designed as a household supply for separate, well-spaced episodes of acute pain rather than for daily ongoing use.
Courier Pharmacy provides expert guidance to help you use this medicine safely and get the most from your treatment.
A dual-ingredient analgesic, in a larger household-supply pack
Co-Codamol 8/500mg 100 tablets are a dual-ingredient analgesic. It is formulated for the short-term relief of moderate pain in adults and young people aged 12 and over. Each tablet contains paracetamol 500mg and codeine phosphate 8mg. Paracetamol provides central analgesia and antipyretic action. The codeine adds a mild opioid layer that meaningfully extends the pain-relieving effect beyond what paracetamol achieves on its own.
The 100-tablet pack offers a larger household supply for adults who experience occasional, separated episodes of acute moderate pain. This can include recurrent dental flare-ups, periodic migraine, intermittent back pain, or recovery periods after minor procedures.
Where it sits in the pain ladder
It sits in a clear therapeutic position: above single-ingredient paracetamol or ibuprofen. However, co-codamol sits below prescription-strength co-codamol formulations such as 15/500 or 30/500. For many people experiencing pain that a standard paracetamol dose has not resolved, it is the appropriate next step.
Why it’s a pharmacy medicine
Because it contains codeine, Co-Codamol 8/500mg is classified as a pharmacy medicine (P) and must be purchased from a registered pharmacy under pharmacist supervision. That is not bureaucracy for its own sake; codeine carries a genuine risk of dependence with overuse, and the pharmacist check is a meaningful safeguard.
The larger 100-tablet pack size makes that pharmacist check even more important. This is because it reduces the number of separate purchases needed and increases the responsibility of using the medicine in line with the three-day rule.
Our team at Courier Pharmacy takes that responsibility seriously, giving you the guidance to use this medicine safely and effectively across the lifespan of the pack.

When everyday pain relief just isn’t cutting it, you need something that actually steps up. This is where co-codamol 8/500mg tablets come in.
Pain that won’t budge is more than uncomfortable; it disrupts your day, your focus, and sometimes your sense of control. Co-Codamol 8/500mg 100 tablets combine two well-established active ingredients, paracetamol and codeine phosphate, to tackle moderate pain that has not responded to paracetamol alone.
Available as a pharmacy medicine, this is a practical option for adults who need a small but meaningful step up in pain relief without a prescription, supplied in a larger 100-tablet pack to support multiple short, separated courses of treatment over time.
At Courier Pharmacy, we believe healthcare should fit the person, not force the person to fit the system. That means honest information, expert guidance, and a team that is here for you whether you are buying something or just need an answer.
Five things worth knowing straight away
Co-Codamol 8/500mg contains paracetamol 500mg and codeine phosphate 8mg per tablet.
It is a pharmacy medicine (P), available without a prescription but only from a registered pharmacy under pharmacist supervision.
Codeine is an opioid; do not use Co-Codamol 8/500mg for more than three consecutive days without medical advice.
Do not take it alongside other paracetamol-containing products, as accidental overdose is a preventable but genuine risk.
It is not suitable for children under 12, people known to be ultra-rapid codeine metabolisers, or those who are pregnant or breastfeeding.
Treatment dosage: Co-Codamol 8/500mg 100 tablets
Standard adult and adolescent dosing
For adults and young people aged 16 and over: take one to two tablets every four to six hours as needed. Do not take more than eight tablets in any 24-hour period. For young people aged 12 to 15: take one tablet every six hours as needed, up to a maximum of four tablets in 24 hours. Do not give this medicine to children under 12 years of age.
How to take the tablets
Swallow tablets whole with a full glass of water. They may be taken with or without food, though taking them after a light meal or snack can reduce the chance of nausea. Do not exceed the stated dose and, critically, do not use Co-Codamol 8/500mg for more than three consecutive days. If your pain has not improved within three days, stop taking the tablets and speak to your pharmacist or GP.
Avoiding accidental paracetamol overdose
Do not take Co-Codamol 8/500mg at the same time as any other paracetamol-containing product. This includes many common cold remedies, flu treatments, and other combination painkillers sold over the counter. Check the ingredients of everything you are taking before adding Co-Codamol 8/500mg to your regimen.
Why pack size doesn’t change the dosing rules
The larger 100-tablet pack does not change the maximum daily dose or the three-day duration limit. It simply provides a longer household supply for people who experience separate, well-spaced episodes of acute pain over several months. Each new course should still be limited to three consecutive days at the recommended doses above.
Overview of Co-Codamol 8/500mg 100 tablets
Five key facts
Co-Codamol is a well-established combination analgesic that has been in widespread clinical use in the UK for decades.
The 8mg codeine dose places this product at the lower end of the co-codamol range; higher-strength formulations (15/500 and 30/500) are prescription-only.
Codeine is a prodrug: it is inactive until converted to morphine by the liver enzyme CYP2D6, which is why genetic variation in this enzyme affects how well the medicine works and how safe it is for different individuals.
The three-day limit is a regulatory and clinical safeguard, not an arbitrary rule; regular use beyond this significantly increases dependence risk and can trigger medication overuse headache.
Paracetamol toxicity from accidental double-dosing is one of the most common causes of acute liver failure in the UK, making it essential to check all medicines for paracetamol content before taking Co-Codamol 8/500mg.
Where it sits on the analgesic ladder
Co-Codamol occupies a specific and well-defined place in the analgesic ladder. The World Health Organisation analgesic ladder, originally developed for cancer pain management but now widely applied to acute pain, identifies three broad steps: non-opioid analgesics, mild opioids combined with non-opioids, and strong opioids. Co-Codamol 8/500mg sits firmly on the second rung, adding a gentle opioid component to paracetamol’s central analgesic effect. For acute moderate pain that has genuinely not responded to step-one options, this is the clinically appropriate next move.
Why 8mg codeine
The 8mg codeine dose is lower than that found in Solpadeine Max (12.8mg) or prescription co-codamol preparations. This makes it a conservative step-up option with a reduced opioid burden. For some people, 8mg of codeine will provide meaningful additional analgesia; for poor metabolisers of codeine, who lack functional CYP2D6 enzyme activity, the codeine component will contribute little because very little morphine is produced. This does not make the product ineffective for those individuals, as paracetamol remains fully active, but it does explain why co-codamol is not equally effective for everyone.
Why a 100-tablet pack, and how to think about it
The 100-tablet pack is not a green light for ongoing daily use. At the maximum adult dose of eight tablets per day, a 100-tablet pack technically covers around twelve to thirteen days. That maximum is not how the pack should be used. The pack is intended as a household supply for separate, well-spaced episodes of acute pain over several months, with each individual episode capped at three consecutive days. Many adults will use a 100-tablet pack across multiple short courses spread over many months, which is exactly the right way to think about it.
When pain is recurring
People managing chronic or recurrent pain conditions, including those living with fibromyalgia, musculoskeletal pain, or conditions associated with chronic fatigue, often find themselves using OTC analgesics during acute flare-ups. While Co-Codamol 8/500mg can play a role in short-term acute management, it is not a substitute for a proper pain management plan. Our pharmacists at Courier Pharmacy can be a useful starting point for conversations about what else might be available, including whether a referral or prescription route might offer more targeted support.
Medication overuse headache
Medication overuse headache is a consequence of frequent analgesic use that is worth understanding before you start, particularly with a larger pack at home. Taking any analgesic, including paracetamol-codeine combinations, for more than ten to fifteen days per month can paradoxically increase headache frequency and severity. This is particularly relevant for people who use Co-Codamol 8/500mg for recurring headaches. If headaches are a regular problem, seeking a proper diagnosis through your GP is far more useful than repeated short courses of OTC analgesia.
Why choose Courier Pharmacy for Co-Codamol 8/500mg 100 tablets
Healthcare that fits the person
At Courier Pharmacy, we built our service around a belief we take seriously: healthcare should fit the person, not force the person to fit the system. When you buy Co-Codamol 8/500mg from us, you are getting more than a packet of tablets; you are getting access to a team that will make sure it is genuinely the right option for your situation. Our approach is shaped by the philosophy of Dr Ada Jex-Cori, our brand pharmacist, who built her career on the idea that expert care should be honest, accessible, and personalised. Her message is straightforward: you are not broken. The system is. We are here to change that.
Support beyond the transaction
We know that people managing recurring or complex pain, whether from a chronic condition, a long-term musculoskeletal issue, or the difficult territory of fibromyalgia or CFS/ME, often end up self-managing with OTC medicines because the system has not yet offered something more targeted. If that sounds familiar, Co-Codamol 8/500mg may be a useful short-term tool, but we would also welcome the chance to talk through broader options. Our pharmacists can discuss prescription alternatives, signpost referral pathways, and help you build a clearer picture of your pain management options without making you feel like a number.
Trust over conversions
Trust matters to us more than conversions. Courier Pharmacy operates under GPhC regulation, references only NHS, NICE, BNF, and peer-reviewed sources in our content, and will tell you honestly when a product is not right for you. If Co-Codamol 8/500mg is not appropriate for your situation, we will explain why and suggest a better alternative. That is what genuine guidance looks like.

Active ingredients in Co-Codamol 8/500mg 100 tablets
Paracetamol 500mg
Each tablet contains paracetamol 500mg, one of the most widely used analgesics and antipyretics in the world. Its mechanism of action is not fully understood, but it is thought to involve inhibition of a prostaglandin-synthesising enzyme in the central nervous system, raising the pain threshold and reducing fever without the anti-inflammatory or gastric effects associated with NSAIDs.
Codeine phosphate 8mg
Each tablet also contains codeine phosphate 8mg, a naturally occurring opium alkaloid and mild opioid prodrug. It exerts its analgesic effect primarily through its conversion to morphine in the liver, where the CYP2D6 enzyme is responsible for the biotransformation.
Why the combination works
The combination of paracetamol and codeine produces additive analgesia: each ingredient contributes independently through its own mechanism, and together they provide broader pain coverage than either alone. At 8mg, the codeine dose is at the lower end of the therapeutic range, providing meaningful benefit in individuals with normal or extensive CYP2D6 activity while limiting the opioid load and associated side effects. Unlike Solpadeine Max, this formulation does not contain caffeine, making it slightly more straightforward for people who are sensitive to caffeine or who take this medicine in the evening.
What are Co-Codamol 8/500mg 100 tablets used for?
Indications and typical use cases
Co-Codamol 8/500mg 100 tablets are indicated for the short-term relief of acute moderate pain that has not been adequately controlled by paracetamol, ibuprofen, or aspirin used alone. Common presentations include dental pain following a procedure or abscess, tension headache or migraine, back pain, period pain, rheumatic and muscular aches, and minor injuries. The operative word is 'acute': this product is designed for defined episodes of pain, not for daily or chronic use.
When it's the right choice
It is the right choice when you have already tried a single-ingredient analgesic at a therapeutic dose, and it has not provided sufficient relief. Taking paracetamol 1000mg or ibuprofen 400mg and still being unable to function is a reasonable trigger to step up to co-codamol. It is not the right choice as a first-line option for mild pain, and it is definitely not appropriate for pain that has been present for weeks or months without a diagnosis.
When it's a sign to ask for a review
If you find yourself reaching for Co-Codamol 8/500mg regularly, especially with a 100-tablet pack on hand, that is a signal that your pain management needs a proper review. Recurring pain has causes worth investigating, and regular codeine use brings its own risks. Our pharmacists at Courier Pharmacy can help you think through next steps, whether that is a GP referral, a prescription alternative, or a conversation about what other options exist.
How do Co-Codamol 8/500mg 100 tablets work?
Paracetamol's central action
Paracetamol's analgesic action is primarily central. It is thought to inhibit a variant of the cyclo-oxygenase enzyme found in the brain and spinal cord, reducing prostaglandin synthesis in the central nervous system and raising the pain threshold. Unlike NSAIDs such as ibuprofen, paracetamol has minimal activity against peripheral inflammation, which is why it works well for pain but less well for inflammatory conditions like arthritis where peripheral prostaglandin activity is the main driver. It also has a well-established antipyretic effect, reducing elevated body temperature by acting on the hypothalamic heat-regulating centre.
Codeine's prodrug pathway
Codeine is a prodrug, meaning it is pharmacologically inactive in its original form and must be converted to an active metabolite to exert its effects. In the liver, the enzyme CYP2D6 converts approximately 5 to 10 per cent of a codeine dose into morphine, which then binds to mu-opioid receptors in the brain, spinal cord, and peripheral tissues. Mu-opioid receptor activation reduces the transmission of pain signals, alters the emotional response to pain, and produces mild sedation. The remaining codeine is metabolised to norcodeine and codeine-6-glucuronide, which contribute minor additional analgesic activity.
Why people respond differently
The degree to which codeine is converted to morphine varies significantly between individuals, depending on CYP2D6 genetic status. There are four broad phenotypes. Poor metabolisers, who carry two non-functional CYP2D6 alleles, produce very little morphine and may find the codeine component provides minimal benefit. Intermediate metabolisers have reduced enzyme activity. Extensive metabolisers, the majority of the population, metabolise codeine at a typical rate. Ultra-rapid metabolisers, who carry gene duplications leading to excessive CYP2D6 activity, convert codeine to morphine rapidly and in larger quantities, creating a risk of morphine toxicity even at standard doses.
Why 8mg works for most adults
At the 8mg dose in Co-Codamol 8/500mg, the amount of morphine produced even in extensive metabolisers is modest, which is part of what makes this a pharmacy rather than a prescription medicine. The analgesic contribution of codeine at this dose adds meaningfully to paracetamol's effect for most people without carrying the side effect burden of higher opioid doses. The combination provides better pain control than paracetamol alone by addressing the pain signal through two distinct biological pathways simultaneously.
How to use Co-Codamol 8/500mg 100 tablets
Take the lowest effective dose
Take the lowest number of tablets that provides adequate relief. For many people, one tablet every six hours is sufficient; two tablets every four to six hours is the higher end of the adult dose range and should be reserved for when one tablet genuinely has not been enough. Swallow tablets with a full glass of water. Taking them after a light meal or snack reduces the likelihood of nausea, which is the most common short-term side effect. Space doses at least four hours apart to allow the paracetamol component to clear partially before the next dose.
Check every other medicine for paracetamol
Check every other medicine in your cabinet for paracetamol before starting a course of Co-Codamol 8/500mg. Cold and flu remedies, night-nurse products, and many other combination medicines contain paracetamol. Taking them alongside Co-Codamol 8/500mg can push your daily paracetamol intake dangerously high without you realising it. The safe daily limit for adults is 4000mg, which is eight standard paracetamol tablets. At two Co-Codamol 8/500mg tablets four times daily, you are already at that ceiling, leaving no room for additional paracetamol from other sources.
Three days, then stop
Keep to three consecutive days. This is the single most important instruction on the pack, and it doesn't change just because you have a larger 100-tablet supply at home. If your pain is still present at day three, stopping the medicine and speaking to your pharmacist or GP is the right move. Pain that persists deserves a clinical assessment, not an extended OTC analgesic course. If you notice that stopping Co-Codamol 8/500mg feels harder than expected, with restlessness, irritability, or a worsening of your symptoms, speak to your pharmacist promptly; these can be early signs of codeine dependence.
Storing a larger pack at home
Keep the pack out of sight and reach of children and visitors. Store it at room temperature, below 25 degrees Celsius, in the original packaging. A larger 100-tablet pack at home means you carry a small but real responsibility to make sure no one else can access it accidentally, especially in households with teenagers, frequent visitors, or vulnerable adults.
Warnings and precautions for Co-Codamol 8/500mg 100 tablets
Who should not take this medicine
Do not take Co-Codamol 8/500mg if you are allergic to paracetamol, codeine phosphate, or any other ingredient in the tablets. It is contraindicated in children under 12 years of age, in people known to be ultra-rapid metabolisers of codeine, in those with significant respiratory depression or obstructive airways disease, and in those with severe hepatic impairment. If you have a history of liver disease or drink alcohol regularly, paracetamol should be used with particular care; discuss your pain relief options with your pharmacist before taking this medicine.
Codeine dependence
Codeine dependence is a recognised risk even with over-the-counter formulations. The risk is low within a three-day course for most people, but it increases with longer use, higher doses, and in individuals with a predisposition to substance dependence. People with a personal or family history of addiction or substance misuse should discuss alternatives with their pharmacist before taking any codeine-containing medicine. Signs of developing dependence include needing the medicine more often than the directions state, taking more than the recommended dose, or finding it difficult to stop. With a 100-tablet pack at home, this risk is worth understanding clearly: the pack is designed for separate, short courses spaced apart, not for ongoing daily use.
Respiratory depression
Respiratory depression is a serious but rare risk at the doses found in Co-Codamol 8/500mg. The risk is higher in ultra-rapid metabolisers, in people with existing respiratory conditions, in older adults, and when co-administered with other CNS depressants, including alcohol, benzodiazepines, or sedating antihistamines. If you or someone else who has taken this medicine develops slowed or laboured breathing, unusual drowsiness, or becomes difficult to rouse, seek emergency medical attention immediately.
Paracetamol liver toxicity
Paracetamol liver toxicity is the most serious risk with this medicine, but it is almost entirely preventable. The maximum safe adult dose of paracetamol is 4000mg in 24 hours, equivalent to eight standard 500mg tablets. Exceeding this, even by a modest amount over several days, can cause serious and sometimes irreversible liver damage. The danger is that early symptoms of paracetamol overdose, nausea, vomiting, and abdominal pain, are mild and may not appear for 24 hours, during which significant liver injury may already be occurring. If you think you may have taken too much, seek emergency care immediately.
Pregnancy and breastfeeding
Codeine is not recommended during pregnancy, particularly in the third trimester. It is not safe for breastfeeding mothers, as codeine passes into breast milk and, in ultra-rapid metabolisers, can result in the infant receiving toxic morphine levels. If you are pregnant, planning a pregnancy, or breastfeeding, paracetamol alone is the preferred analgesic option. Speak to your midwife or GP for personalised advice.
Side effects of Co-Codamol 8/500mg 100 tablets
Common side effects
Side effects with Co-Codamol 8/500mg at the recommended dose and duration are generally mild and manageable. Constipation is the most predictable effect of codeine and affects the majority of people who take it, even for short courses. Codeine slows intestinal motility by acting on opioid receptors in the gut. Staying well hydrated and maintaining fibre intake during your course helps. Nausea occurs in some people, particularly at the start of treatment or with higher doses. Taking the tablets after food reduces this considerably.
Less common side effects
Less common side effects include drowsiness or lightheadedness, dry mouth, dizziness, and mild headache. Some people experience a mild euphoric sensation with the codeine component; while this is not itself harmful in a short course, it is part of why codeine has misuse potential and why the three-day limit matters. Skin reactions, including rash or itching, can occur in people with sensitivities to either active ingredient.
Rare but serious side effects
Rare but serious side effects include severe allergic reactions such as anaphylaxis, respiratory depression, particularly in ultra-rapid metabolisers or with accidental overdose, liver damage from paracetamol toxicity, and blood disorders. These are uncommon but reinforce the importance of taking this medicine exactly as directed, for no longer than recommended. If you develop signs of a serious reaction, including difficulty breathing, severe rash, confusion, or yellowing of the skin or eyes, seek emergency medical attention immediately.
Yellow Card reporting
You can report suspected adverse drug reactions to the MHRA via the Yellow Card scheme at yellowcard.mhra.gov.uk. Patient reports contribute to ongoing monitoring of medicines in real-world use and help protect others.
Drug interactions with Co-Codamol 8/500mg 100 tablets
Always tell your pharmacist what else you're taking
Tell your pharmacist about all medicines you are currently taking before purchasing Co-Codamol 8/500mg. This includes prescription medicines, over-the-counter products, vitamins, and herbal remedies. Several important interactions apply to this formulation.
Other paracetamol-containing products
Other paracetamol-containing products are the most clinically significant interaction in everyday use. Many common medicines, including cold and flu remedies, decongestant tablets, and other combination painkillers, contain paracetamol. Taking these alongside Co-Codamol 8/500mg can easily result in exceeding the safe daily dose of 4000mg without the person being aware. This risk is entirely preventable by checking ingredient labels before combining any products.
CNS depressants
CNS depressants interact with the codeine component by additive or synergistic sedation and respiratory depression. This group includes alcohol, benzodiazepines, other opioid analgesics, sedating antihistamines (found in some sleep aids and allergy medicines), tricyclic antidepressants, and antipsychotics. Combining codeine with any of these increases the risk of excessive sedation, impaired driving ability, and, in severe cases, life-threatening respiratory depression. Avoid alcohol completely during a course of Co-Codamol 8/500mg.
MAOIs
Monoamine oxidase inhibitors (MAOIs) are contraindicated with codeine. MAOIs include certain antidepressants such as phenelzine and tranylcypromine, and some medicines used in Parkinson's disease. Codeine should not be taken during MAOI treatment or within 14 days of stopping an MAOI. If you are unsure whether any of your medicines are MAOIs, ask your pharmacist.
Anticoagulants and CYP2D6 inhibitors
Warfarin and anticoagulants may be affected by regular high-dose paracetamol. At the doses and short duration typical of Co-Codamol 8/500mg use, the interaction is unlikely to be clinically significant; however, patients on anticoagulation therapy should inform their anticoagulation clinic of any analgesic use. CYP2D6 inhibitors, including some antidepressants such as fluoxetine, paroxetine, and bupropion, can reduce the conversion of codeine to morphine, potentially diminishing the analgesic effect of the codeine component.
Frequently asked questions about Co-Codamol 8/500mg 100 tablets
What is Co-Codamol 8/500mg used for?
Co-Codamol 8/500mg 100 tablets are used for the short-term relief of moderate pain that has not been adequately controlled by paracetamol, ibuprofen, or aspirin alone. Typical uses include dental pain, headache, back pain, period pain, and muscular aches. It should only be used for up to three consecutive days at a time.
What are the ingredients in Co-Codamol 8/500mg?
Each tablet contains paracetamol 500mg and codeine phosphate 8mg. Paracetamol is the primary analgesic, providing central pain relief and fever reduction. Codeine phosphate is a mild opioid that is converted to morphine in the liver and adds an additional analgesic layer. Unlike some other codeine-containing combination products, this formulation does not contain caffeine.
How many Co-Codamol 8/500mg tablets can I take at once?
Adults aged 16 and over may take one to two tablets every four to six hours as needed, up to a maximum of eight tablets in 24 hours. Young people aged 12 to 15 should take one tablet every six hours, maximum four in 24 hours. Do not exceed the stated dose, and do not take the medicine for more than three consecutive days without medical advice.
Why is Co-Codamol 8/500mg supplied in a 100-tablet pack?
The 100-tablet pack is intended as a household supply for adults who experience occasional, separated episodes of acute moderate pain over several months. Each individual episode is still capped at three consecutive days. The larger pack reduces the number of separate purchases needed, but it does not change the daily dose, the three-day rule, or the fact that codeine should not be used for ongoing daily pain.
Can I take Co-Codamol 8/500mg with paracetamol?
No. Each Co-Codamol 8/500mg tablet already contains 500mg of paracetamol. Taking additional paracetamol at the same time risks exceeding the safe daily maximum of 4000mg, which can cause serious liver damage. Always check the ingredients of all other medicines you are taking before using Co-Codamol 8/500mg.
Can I take Co-Codamol 8/500mg with ibuprofen?
In most cases, yes. Paracetamol and ibuprofen work through different mechanisms and can generally be combined safely. However, confirm with your pharmacist first, particularly if you have a history of stomach problems, kidney disease, heart disease, or are taking other medicines. Some conditions and drug combinations make this combination inadvisable.
How long can I take Co-Codamol 8/500mg for?
No longer than three consecutive days at a time. If your pain has not improved within that time, stop taking the tablets and seek advice from your pharmacist or GP. Extended use significantly increases the risk of codeine dependence and can cause medication overuse headache in people who use analgesics frequently for headaches.
Is Co-Codamol 8/500mg addictive?
Codeine has the potential to cause physical dependence with regular use, even at the lower doses found in over-the-counter formulations. The risk within a properly observed three-day course is low for most people, but it is not zero. People with a personal or family history of substance misuse are at higher risk. With a 100-tablet pack at home, the responsibility to use the medicine in line with the three-day rule is even more important. If stopping feels difficult, speak to your pharmacist or GP.
What is the difference between Co-Codamol 8/500mg and Co-Codamol 30/500mg?
The numbers refer to the codeine and paracetamol doses, respectively. Co-Codamol 8/500mg contains 8mg of codeine, is a pharmacy medicine available without a prescription, and is intended for moderate pain. Co-Codamol 30/500mg contains 30mg of codeine, is a prescription-only medicine, and is used for more severe pain under medical supervision. Higher codeine doses carry greater risks of dependence and respiratory depression.
Can I drink alcohol while taking Co-Codamol 8/500mg?
No. Alcohol increases the sedative and respiratory depressant effects of codeine, raising the risk of dangerous over-sedation. It also increases the risk of liver damage from paracetamol, particularly in people who drink regularly. Avoid alcohol completely during a course of Co-Codamol 8/500mg.
Is Co-Codamol 8/500mg suitable during pregnancy?
Codeine is not recommended during pregnancy, particularly in the third trimester, and should not be taken by breastfeeding mothers. Codeine passes into breast milk, and in mothers who are ultra-rapid metabolisers, infants can receive morphine levels sufficient to cause harm. If you are pregnant or breastfeeding and need pain relief, paracetamol alone is the recommended first choice; seek advice from your midwife or GP.
Can children take Co-Codamol 8/500mg?
Co-Codamol 8/500mg is not suitable for children under 12. For young people aged 12 to 15, the dose is one tablet every 6 hours, up to 4 in 24 hours, and it must not be used for more than 3 days. Codeine is contraindicated in under-12s following MHRA guidance, due to the risk of respiratory depression especially in ultra-rapid metabolisers.
What should I do if I accidentally take too much Co-Codamol 8/500mg?
Go to your nearest emergency department immediately, even if you feel well. Paracetamol overdose can cause serious liver damage that may not produce obvious symptoms for 24 to 48 hours. Do not wait to see if symptoms develop. Take the medicine packet with you so medical staff know exactly what you have taken and in what quantity.
Does Co-Codamol 8/500mg cause constipation?
Yes. Constipation is one of the most common side effects of codeine, affecting the majority of people who take it. Codeine slows gut movement by acting on opioid receptors in the intestinal wall. Staying well hydrated and maintaining fibre intake during treatment helps. For a three-day course, it is usually manageable. If constipation is already a concern for you, discuss this with your pharmacist.
Can I drive after taking Co-Codamol 8/500mg?
Codeine can cause drowsiness, dizziness, and impaired reaction time. You should not drive or operate heavy machinery until you know how this medicine affects you. Under UK law, driving with codeine in your system above specified limits can be a criminal offence even if you have taken it as prescribed. If you feel drowsy, do not drive.
What is an ultra-rapid codeine metaboliser?
Ultra-rapid metabolisers carry a gene variant (usually CYP2D6 duplication) that converts codeine to morphine much faster and in larger quantities than normal. Even a standard dose of codeine can produce high enough morphine levels to cause toxicity in these individuals, including severe drowsiness, slow breathing, and confusion. Ultra-rapid metabolisers should not use codeine-containing products. Genetic testing for metaboliser status is available through some NHS pathways.
Is Co-Codamol 8/500mg the same as Solpadol or Tylex?
Solpadol and Tylex are branded co-codamol preparations, but they contain codeine 30mg and paracetamol 500mg and are prescription-only medicines. Co-Codamol 8/500mg contains a lower codeine dose and is a pharmacy medicine. While all three are co-codamol products, the difference in codeine strength means they are not interchangeable. Always check the strength carefully.
Can Co-Codamol 8/500mg cause headaches?
There are two relevant mechanisms here. First, the caffeine withdrawal headache does not apply to this formulation as it does not contain caffeine. Second, medication overuse headache is a real risk for people who take analgesics frequently. Using Co-Codamol 8/500mg for more than ten days per month can paradoxically worsen headache patterns. If you have frequent headaches, seek a diagnosis rather than relying on regular OTC analgesics.
How should I store Co-Codamol 8/500mg 100 tablets?
Store at room temperature, below 25 degrees Celsius, in the original packaging to protect from moisture and light. Keep out of the sight and reach of children. With a larger 100-tablet pack at home, take particular care to store the medicine somewhere children, teenagers, and visitors cannot access it. Do not use after the expiry date on the pack. Dispose of unused medicines responsibly by returning them to a pharmacy rather than putting them in household waste or flushing them.
What is the difference between Co-Codamol 8/500mg and Solpadeine Max?
Both contain paracetamol 500mg and codeine as active ingredients, but there are two key differences. Solpadeine Max contains 12.8mg of codeine, a higher dose than the 8mg in Co-Codamol 8/500mg. Solpadeine Max also contains caffeine 30mg as an analgesic adjuvant, while Co-Codamol 8/500mg does not. For people who are caffeine-sensitive or who take this medicine in the evening, Co-Codamol 8/500mg may be a more comfortable option.
Can I take Co-Codamol 8/500mg for period pain?
Yes. Primary dysmenorrhoea is a recognised indication for co-codamol when paracetamol or ibuprofen alone has not been sufficient. For many people, ibuprofen is actually more effective for period pain due to its anti-inflammatory action targeting prostaglandins that drive menstrual cramping. If you consistently need step-up analgesia for your periods, it is worth discussing prescription options or hormonal management with your GP.
