Peptac Peppermint Liquid is an off-white oral suspension with a peppermint flavour. Firstly, it contains three active ingredients per 5ml: sodium alginate 250mg, sodium bicarbonate 133.5mg, and calcium carbonate 80mg.
Also, the 500ml pack is one of the largest bottle sizes available. Firstly, this makes it cost-effective for regular users.
However, Peptac is described as an antacid with reflux suppressant action. Firstly, it combines both acid-neutralising and raft-forming mechanisms.
Peptac vs Gaviscon Original (essentially equivalent)
Peptac and Gaviscon Original share the same three active ingredients at very similar concentrations. Firstly, both are triple-action alginate raft-formers with acid neutralisation.
Also, Gaviscon Original per 10ml contains: sodium alginate 500mg, sodium bicarbonate 267mg, calcium carbonate 160mg.
However, Peptac per 10ml contains: sodium alginate 500mg, sodium bicarbonate 267mg, calcium carbonate 160mg. Firstly, the composition is essentially identical.
Furthermore, the clinical effect is expected to be equivalent. Firstly, Peptac is usually offered at a lower price than the branded Gaviscon Original.
The triple-action mechanism
Peptac works through three complementary mechanisms. Firstly, sodium alginate reacts with stomach acid to form alginic acid gel.
Also, sodium bicarbonate reacts with stomach acid to release carbon dioxide bubbles (which get trapped in the gel and make it float) and to neutralise some acid.
However, calcium carbonate provides additional acid neutralisation on contact with stomach acid. Firstly, this gives immediate acid-neutralising effect alongside the raft formation.
Furthermore, the alginate raft floats on top of the stomach contents. Firstly, this physical barrier blocks stomach acid and contents from refluxing up into the oesophagus for up to 4 hours.

A cost-effective alginate raft-former with triple action for heartburn, indigestion, and acid reflux
Peptac Peppermint Liquid is a reflux suppressant containing three active ingredients: sodium alginate, sodium bicarbonate, and calcium carbonate. Firstly, it is a general sale list (GSL) medicine from Pinewood Healthcare (owned by Teva).
Also, Peptac is essentially the generic equivalent of Gaviscon Original. Firstly, it shares the same three active ingredients at the same concentrations, with the same triple-action mechanism.
However, Peptac is usually offered at a lower price than the branded Gaviscon Original. Firstly, this makes it an economical option for regular users.
Furthermore, the 500ml pack size is one of the largest available. Firstly, this makes it particularly cost-effective for regular use.
Above all, Peptac works through a triple-action mechanism. Firstly, sodium alginate reacts with stomach acid to form a floating raft, sodium bicarbonate neutralises acid and provides CO2 for raft buoyancy, and calcium carbonate adds further acid neutralisation.
Also, this raft floats on top of the stomach contents. Firstly, it physically blocks stomach acid and contents from refluxing up into the oesophagus for up to 4 hours.
However, this is different from antacids alone (which just neutralise acid) and from PPIs (which reduce acid production). Firstly, Peptac combines both raft-forming and acid-neutralising actions.
Furthermore, one distinctive advantage of Peptac is the lower age limit. Firstly, it is suitable for children as young as 6 years old, unlike Gaviscon Advance (12+).
Also, adults and children 12 and over take 10-20ml (2-4 x 5ml spoonfuls) after meals and at bedtime, up to four times daily. Firstly, children 6-11 take a smaller dose of 5-10ml.
However, the peppermint flavour makes the suspension palatable. Firstly, this can help with compliance for both adults and children.
Furthermore, Peptac is sugar-free and gluten-free. Firstly, it uses sodium saccharin as a sweetener.
Above all, Peptac contains parabens (ethyl, propyl, and butyl parahydroxybenzoates) as preservatives. Firstly, patients with paraben allergy should avoid this product.
Also, it is safe to use during pregnancy and breastfeeding based on the SmPC. Firstly, however, ongoing symptoms in pregnancy should be discussed with your midwife or GP.
Furthermore, seek medical advice if symptoms persist for more than 7 days, or if you have symptoms suggesting more serious conditions.
At Courier Pharmacy, we stock Peptac Peppermint Liquid alongside other reflux and acid options. Our pharmacy team can advise on whether it fits your specific symptoms and situation.
When to see a doctor rather than self-treat
Peptac Peppermint Liquid is for short-term self-care of heartburn, indigestion, and acid reflux. However, some situations need medical assessment rather than continued over-the-counter treatment.
Symptoms lasting more than 7 days without improvement
Vomiting blood or coffee-ground vomit; passing black tarry stools or bright red blood in stools (possible GI bleeding, call 999)
Difficulty or painful swallowing, or food sticking on the way down (possible oesophageal condition needing investigation)
Unintended weight loss, persistent vomiting, or loss of appetite
New or worsening symptoms in someone over 55 (new-onset reflux needs endoscopic assessment)
Chest pain (particularly if severe, radiating to arm/jaw, or with breathlessness or sweating). Call 999 if uncertain, because heart symptoms can be mistaken for heartburn
Severe abdominal pain that doesn’t settle with treatment
Iron deficiency anaemia (may indicate hidden bleeding)
Frequent or recurrent symptoms that come back soon after stopping treatment (may need PPI therapy)
If you have paraben allergy, do not take Peptac. Firstly, it contains ethyl, propyl, and butyl parahydroxybenzoates
If you have significant heart failure, kidney disease, or are on a low-salt diet, check with your GP or pharmacist because of the sodium content
Children under 6: do not give Peptac. Firstly, use Infant Gaviscon or seek medical advice
Five key takeaways
Peptac Peppermint Liquid is a cost-effective generic equivalent of Gaviscon Original, containing sodium alginate 250mg, sodium bicarbonate 133.5mg, and calcium carbonate 80mg per 5ml.

500ml pack size is economical for regular use. General sale list (GSL) medicine. Available from Courier Pharmacy.
What is Peptac Peppermint Liquid: overview
Where Peptac fits in acid-related self-care
Heartburn, indigestion, and acid reflux are common. Firstly, several over-the-counter options exist.
Also, antacids (Rennie, Tums) neutralise stomach acid for fast but short-lived relief.
However, alginate raft-formers (Peptac, Gaviscon Original, Gaviscon Advance) form a physical barrier that reduces reflux for longer.
Furthermore, H2 antagonists (famotidine) and PPIs (omeprazole 10mg OTC as Zanprol) reduce acid production for hours to days.
Peptac vs Gaviscon Original (the direct comparison)
Peptac and Gaviscon Original contain essentially the same active ingredients at the same concentrations. Firstly, both are triple-action alginate raft-formers with acid neutralisation.
Also, the clinical effect is expected to be equivalent. Firstly, both are suitable from age 6.
However, Peptac is usually offered at a lower price than the branded Gaviscon Original. Firstly, choice often depends on cost and personal brand preference.
Peptac vs Gaviscon Advance
Gaviscon Advance contains twice the sodium alginate concentration (1000mg vs 500mg per 10ml) and uses potassium bicarbonate instead of sodium bicarbonate. Firstly, Advance is stronger and lower in sodium.
Also, Gaviscon Advance is suitable from age 12, while Peptac is suitable from age 6.
However, Peptac is usually more economical. Firstly, choice depends on symptom severity, age, and budget considerations.
Peptac vs Acidex and supermarket own-brands
Peptac, Acidex, and various supermarket own-brands (Boots, Tesco, Well) are all made by Pinewood Healthcare with identical composition. Firstly, they share the same SmPC (EMC 15318).
Also, choice between these usually comes down to pack size availability, price, and personal preference.
Peptac vs Rennie or Tums (simple antacids)
Rennie and Tums contain calcium carbonate (and magnesium in Rennie). Firstly, they neutralise stomach acid on contact.
Also, this gives fast but short-lived relief (usually 30-60 minutes).
However, Peptac’s raft-forming action gives longer protection (up to 4 hours). Firstly, this is more effective for regurgitation and reflux symptoms than simple antacids alone.
Peptac vs H2 antagonists (Pepcid AC)
Pepcid AC contains famotidine 10mg (OTC H2 antagonist). Firstly, it reduces acid production for 8-12 hours.
Also, Peptac works through a physical raft mechanism with faster onset but shorter duration.
However, the two can be combined for complementary effect.
Peptac vs OTC PPI (Zanprol)
Zanprol contains omeprazole 10mg (OTC PPI). Firstly, it reduces stomach acid production and needs 1-4 days to reach full effect.
Also, Zanprol is used for a 14-day course for frequent heartburn.
However, Peptac works immediately and can be used as needed. Firstly, it can be combined with PPI therapy for breakthrough symptoms.
Peptac vs prescription PPIs
Prescription PPIs (rabeprazole, lansoprazole, omeprazole higher doses) give stronger and longer-lasting acid suppression. Firstly, they are used for confirmed reflux disease and ulcer healing.
Also, Peptac is often used alongside prescription PPIs. Firstly, it provides fast relief for breakthrough reflux while PPIs reduce baseline acid production.
Complementary use with other acid-suppressing medicines
Peptac can be used alongside PPIs (omeprazole, lansoprazole, rabeprazole, esomeprazole) or H2 antagonists (famotidine). Firstly, they work through different mechanisms and complement each other.
However, remember to leave at least 2 hours between Peptac and other oral medicines. Firstly, the alginate can reduce absorption of some drugs.
Short-term use only
Peptac is for short-term (up to 7 days) symptom relief. Firstly, symptoms persisting beyond this need medical assessment.
Also, chronic or frequent reflux may need prescription treatment.

Summary
A cost-effective triple-action alginate raft-former for children 6+ and adults with heartburn, indigestion, and acid reflux.
Contains sodium alginate 250mg, sodium bicarbonate 133.5mg, and calcium carbonate 80mg per 5ml (essentially equivalent to Gaviscon Original).
Distinctive mechanism: forms a floating raft that physically blocks reflux, plus acid neutralisation from bicarbonate and calcium carbonate.
Suitable from age 6 (lower age limit than Gaviscon Advance which is 12+). Safe in pregnancy and breastfeeding.
Sodium alginate is a naturally occurring polysaccharide derived from brown seaweed. Firstly, it has been used medicinally for its viscous, gel-forming properties for many decades.
Also, when sodium alginate contacts stomach acid, it forms alginic acid gel with near-neutral pH.
However, at 250mg per 5ml (500mg per 10ml), Peptac has the same alginate concentration as Gaviscon Original. Firstly, this gives a strong and durable raft.
Sodium bicarbonate 133.5mg per 5ml
Sodium bicarbonate has two roles in Peptac. Firstly, it reacts with stomach acid to release carbon dioxide bubbles that get trapped in the alginate gel, making it float.
Also, sodium bicarbonate provides direct acid neutralisation. Firstly, this adds an antacid component to the raft-forming action.
However, sodium bicarbonate contains sodium, which contributes to the total sodium load of the medicine.
Calcium carbonate 80mg per 5ml
Calcium carbonate provides additional acid neutralisation. Firstly, it also contributes calcium ions that support the raft-forming reaction.
However, patients with hypercalcaemia, nephrocalcinosis, or calcium-containing kidney stones should use with caution due to the calcium content.
What is Peptac Peppermint Liquid for?
Heartburn
Heartburn is the burning sensation in the chest caused by stomach acid refluxing up into the oesophagus. Firstly, Peptac's raft blocks this reflux physically while the bicarbonate and calcium carbonate neutralise acid.
Acid regurgitation
Acid regurgitation is when stomach contents come up into the throat or mouth, often causing a sour or bitter taste. Firstly, the alginate raft prevents this by acting as a physical barrier.
Indigestion (dyspepsia)
Dyspepsia can include a range of upper GI symptoms: stomach discomfort, bloating, nausea, early fullness. Firstly, Peptac can help when acid or reflux is a component.
Symptoms of gastro-oesophageal reflux
These include heartburn, acid regurgitation, chest discomfort, and sometimes cough (particularly at night). Firstly, Peptac addresses the physical process of reflux.
Post-meal symptoms
Symptoms occurring after meals (especially large meals, spicy foods, or lying down soon after eating). Firstly, Peptac taken after meals gives protection during the vulnerable post-meal period.
Night-time reflux
Reflux symptoms during sleep can wake you up or contribute to poor sleep. Firstly, a bedtime dose of Peptac provides overnight protection.
Pregnancy-related heartburn
Heartburn is very common in pregnancy, particularly in the third trimester. Firstly, Peptac can be used during pregnancy per SmPC.
What Peptac isn't for
Peptac is not for chronic acid-related conditions needing PPI therapy. Firstly, prescription PPIs are usually more appropriate for confirmed GORD, oesophagitis, or ulcers.
Also, it is not for chest pain of cardiac origin. Firstly, if chest pain is severe, radiating, or with breathlessness, call 999.
However, it is not for children under 6. Firstly, Infant Gaviscon is a separate product for very young children.
How does Peptac Peppermint Liquid work?
The alginate raft (main mechanism)
Sodium alginate is a viscous, gel-forming polymer. Firstly, when it contacts stomach acid, it precipitates into alginic acid gel.
Also, sodium bicarbonate reacts with stomach acid to release carbon dioxide. Firstly, these CO2 bubbles get trapped in the alginate gel, making it float.
However, this floating gel raft physically blocks stomach contents from refluxing up into the oesophagus. Firstly, the raft has near-neutral pH, so it does not itself irritate the oesophagus if refluxed.
The acid neutralisation (added benefit)
Sodium bicarbonate and calcium carbonate both neutralise stomach acid on contact. Firstly, this reduces acidity of the stomach contents.
Also, this is different from PPIs and H2 antagonists (which reduce acid production). Firstly, antacid neutralisation acts immediately but is short-lived.
Duration of raft protection
The raft can provide up to 4 hours of protection per dose. Firstly, this is longer than the immediate but short-lived neutralisation from simple antacids alone.
However, individual response varies. Firstly, factors like meal composition and gastric motility affect how long the raft lasts.
Not systemically absorbed
Alginic acid is not absorbed into the systemic circulation. Firstly, it acts locally in the stomach and passes through the digestive tract.
Also, small amounts of sodium bicarbonate and calcium carbonate may be absorbed. Firstly, however, this is minimal at recommended doses.

Administration: shake bottle well before use; measure with 5ml spoon or measuring cup provided
Adult and adolescent (12+) dose
Take 10-20ml (two to four 5ml spoonfuls) after meals and at bedtime, up to four times daily. Firstly, do not exceed four doses in any 24-hour period.
Also, most patients take Peptac after meals and at bedtime. Firstly, this covers the times when acid reflux is most common.
Elderly patients
No specific dose reduction is required in adults over 60. Firstly, however, be aware of the sodium content if you have heart failure or fluid retention.
Pregnancy
Peptac can be used in pregnancy. Firstly, clinical studies in over 500 pregnant women plus large postmarketing data show no malformative or feto-toxic effects.
However, if heartburn is severe or persistent in pregnancy, discuss with your midwife or GP.
Breastfeeding
Peptac can be used in breastfeeding. Firstly, the active ingredients are not significantly absorbed and no effects have been shown in breastfed babies of treated mothers.
Renal impairment or heart failure
Use with caution in significant renal impairment, congestive heart failure, or if on a low-salt diet. Firstly, the sodium content may be relevant.
Paraben allergy
Do not use Peptac if you have known paraben allergy. Firstly, it contains ethyl, propyl, and butyl parahydroxybenzoates as preservatives.
However, butyl parahydroxybenzoate specifically is noted in the SmPC as potentially causing allergic reactions (sometimes delayed).
Duration limits
Do not take Peptac for more than 7 days without medical advice. Firstly, persistent symptoms may indicate a more significant condition needing assessment or prescription treatment.
How to take Peptac Peppermint Liquid
Standard adult dose
Adults and children 12 and over: take 10-20ml (two to four 5ml spoonfuls) after meals and at bedtime. Firstly, use up to four times daily.
Shake before use
Shake the bottle well before each dose. Firstly, this ensures the suspension is properly mixed and any sedimentation is dispersed.
How to measure the dose
Use a 5ml medicine spoon or the measuring cup if one is provided. Firstly, do not use household teaspoons as they vary in size.
When to take
Take Peptac after meals and at bedtime. Firstly, this covers the times when acid reflux is most common.
Also, after meals: the raft forms in the presence of stomach acid released for digestion.
However, at bedtime: lying down makes reflux more likely, so a bedtime dose gives overnight protection.
How quickly it works
The alginate raft usually forms within minutes of swallowing the suspension. Firstly, symptom relief is often noticed rapidly.
Also, the raft can provide protection for up to 4 hours per dose.
Separating from other medicines
Above all, leave at least 2 hours between Peptac and other oral medicines. Firstly, the alginate raft can reduce the absorption of some medicines.
Also, particularly important with tetracycline and fluoroquinolone antibiotics, iron salts, thyroid hormones (levothyroxine), chloroquine, and bisphosphonates.
Missed doses
If you miss a dose, take it if symptoms are present or expected. Firstly, however, do not exceed the maximum daily dose.
Stopping treatment
Peptac can be stopped whenever symptoms have settled. Firstly, there is no need to taper.
However, if symptoms return quickly after stopping, consider whether prescription treatment (PPI or H2 antagonist) might be more appropriate.
Do not exceed the stated dose
Do not take more than 4 doses (up to 80ml maximum) in 24 hours. Firstly, exceeding the dose does not improve effect but adds unnecessary sodium load.
Warnings and precautions for Peptac Peppermint Liquid
Paraben allergy
Peptac contains ethyl, propyl, and butyl parahydroxybenzoates as preservatives. Firstly, patients with known paraben allergy should not take Peptac.
However, butyl parahydroxybenzoate specifically is noted in the SmPC as potentially causing allergic reactions (sometimes delayed).
Symptoms lasting more than 7 days
If symptoms persist for more than 7 days, consult a doctor. Firstly, persistent reflux may indicate a more significant condition needing prescription treatment or investigation.
Alarm symptoms (see a doctor before using)
Certain symptoms need medical assessment before using self-care products. Firstly, these include difficulty or painful swallowing, unintended weight loss, persistent vomiting, or vomiting blood.
However, iron deficiency anaemia or new symptoms in someone over 55 also need medical assessment.
Sodium content
Peptac contains sodium from both sodium alginate and sodium bicarbonate. Firstly, this is a consideration for patients on low salt diets, with congestive heart failure, or with renal impairment.
However, discuss with your GP or pharmacist if these apply to you.
Calcium content
Peptac contains calcium from calcium carbonate. Firstly, use with caution in patients with hypercalcaemia, nephrocalcinosis, or recurrent calcium-containing kidney stones.

Rare but significant side effects
Allergic reactions to the parabens or other ingredients are rare but possible. Firstly, symptoms include rash, itching, swelling of face, lips, tongue, or throat, and difficulty breathing.
However, butyl parahydroxybenzoate may cause delayed allergic reactions in susceptible patients.
Serious side effects requiring urgent help
Above all, seek urgent medical help for signs of severe allergic reaction (facial or throat swelling, breathing difficulty, widespread rash). Call 999.
Above all, leave at least 2 hours between Peptac and other oral medicines. Firstly, the alginate raft and antacid effect can reduce absorption of some medicines.
Also, particularly important with tetracycline and fluoroquinolone antibiotics, iron salts, thyroid hormones (levothyroxine), chloroquine, bisphosphonates, and phenothiazines.
Lithium and quinidine
Sodium bicarbonate can reduce plasma lithium levels and increase plasma quinidine levels through renal effects. Firstly, discuss with your GP or pharmacist if you take these medicines.
PPIs and H2 antagonists (compatible)
Peptac can be used alongside PPIs or H2 antagonists. Firstly, no direct interaction is expected.
However, if using both, some prescribers recommend taking Peptac for breakthrough symptoms rather than continuously.
Antacids (compatible)
Peptac already contains antacid components. Firstly, adding another antacid is usually unnecessary.
Anticoagulants and cardiac medicines
No direct interaction with warfarin, DOACs, or standard cardiac medicines. However, the sodium content should be considered in patients with heart failure or on low-sodium diets.
Alcohol
No direct interaction. However, alcohol worsens acid-related symptoms.
