Overview of tadalafil 5mg tablets
Daily, low-dose option for ongoing support
Improves erectile function and urinary symptoms
Suitable for men with diabetes, cardiovascular risk, or enlarged prostate
Can help to increase testosterone levels
Clinically proven, trusted by healthcare professionals
Easy to use, fits into your daily routine
Tadalafil 5mg tablets are a popular choice for men seeking flexible, long-term management of erectile dysfunction. Because you take them daily, you don’t have to plan intimacy around medication—giving you more freedom and less stress [9].
The tablets work by relaxing blood vessels, which improves blood flow not only to the penis but also throughout the body. This action helps men with both erectile dysfunction and urinary symptoms caused by an enlarged prostate (benign prostatic hyperplasia, or BPH) [9], [10].
Tadalafil 5mg tablets are beneficial for men with ongoing health conditions like diabetes or heart disease. Studies show that regular use can improve vascular health, lower inflammation, and may even help boost testosterone in some men [7], [8], [12].
It’s important to use tadalafil 5mg tablets as prescribed and to stay in touch with your healthcare provider for regular check-ins. Most men find the tablets easy to use and well-tolerated, but always report any side effects or concerns [5].
Active ingredient in tadalafil 5mg tablets
Each tablet contains 5mg of tadalafil, a phosphodiesterase type 5 (PDE5) inhibitor. Tadalafil works by relaxing smooth muscle and increasing blood flow, which is essential for treating erectile dysfunction and urinary symptoms [4], [5], [6].
What are tadalafil 5mg tablets used for?
Tadalafil 5mg tablets are prescribed to treat erectile dysfunction, helping men achieve and maintain an erection when sexually aroused [5],[6]. They’re also used to manage urinary symptoms caused by an enlarged prostate (benign prostatic hyperplasia) [10].
For men with diabetes or cardiovascular risk factors, tadalafil 5mg tablets may offer additional benefits—such as improving blood vessel health, reducing inflammation, and supporting testosterone production [7], [8], [12].
This daily, low-dose approach is ideal for men who want more flexibility and spontaneity in their intimate lives, or who need ongoing support for urinary symptoms [9], [10].
How do tadalafil 5mg tablets work?
Before we dive into how tadalafil 5mg tablets work, let’s first understand what actually happens during an erection.
How does an erection occur?
An erection is a carefully coordinated process involving your brain, nerves, hormones, and blood vessels. It all begins with sexual arousal, which thoughts, physical touch, or other sensory cues can spark. When you’re aroused, your brain sends signals through your nervous system that trigger the release of a chemical called nitric oxide in the tissues of your penis. This nitric oxide is key because it boosts levels of a molecule known as cyclic guanosine monophosphate (cGMP) [14].
What does cGMP do?
cGMP acts like a messenger inside your penis, telling the smooth muscles in the walls of blood vessels to relax. It does this by preventing the release of calcium inside those muscle cells. Since calcium causes muscles to contract, blocking its release means the muscles relax instead. When the smooth muscle relaxes, the blood vessels dilate, allowing more blood to flow into the two spongy chambers, the corpora cavernosa [14].
Think of your penis as a sponge that fills with blood when you’re aroused. Thanks to cGMP’s action, the blood vessels open up, blood rushes in, and the penis swells and becomes firm. At the same time, the swelling compresses the veins that usually drain blood, trapping it inside and keeping your erection strong [14].
How does tadalafil 5mg work?
Normally, an enzyme called phosphodiesterase type 5 (PDE5) breaks down cGMP, triggering the release of calcium, which causes muscles to contract and blood vessels to tighten. This leads to the erection fading [14].
Tadalafil 5mg tablets block PDE5, stopping it from breaking down cGMP too quickly. This means cGMP sticks around longer, keeping calcium levels low inside the muscle cells, so the muscles stay relaxed and blood vessels remain open. The result is a firmer, longer-lasting erection that’s ready when you are.
It’s important to remember that tadalafil doesn’t create an erection on its own—you still need sexual stimulation to start the process by releasing nitric oxide. But once that happens, tadalafil helps maintain the erection so you can enjoy your intimate moments without worry [9].
Why erectile dysfunction can signal more than just bedroom troubles
Erectile dysfunction (ED) is often caused by problems with blood vessels, which means it can be an early warning sign for heart disease. Think of ED as the “canary in the mineshaft” — just like miners used to watch canaries for danger, ED can alert you to underlying issues with your cardiovascular health [7], [8].
Because the blood vessels in the penis are smaller and more sensitive, they can show symptoms of narrowing or damage before larger vessels in the heart do. If you’re experiencing ED, it’s a good idea to check in with your doctor about your heart health, too. Taking tadalafil 5mg not only helps with erections but may also support better blood flow and overall vascular function [7], [8].
The risks of a prolonged erection
While erections are a natural and healthy part of sexual activity, there’s such a thing as too much of a good thing. A prolonged erection, known medically as priapism, can be dangerous.
During an erection, blood fills the corpora cavernosa, and the veins that usually drain blood get compressed, keeping the blood trapped inside. If this trapped blood doesn’t receive oxygen-rich blood, the tissues can become damaged. If an erection lasts too long—over four hours—it can cause scarring, tissue damage, and even permanent erectile dysfunction [5].
In severe cases, priapism can lead to tissue death (necrosis), which might require surgery. That’s why any erection lasting more than four hours is a medical emergency, and you should seek immediate help to avoid long-term problems [5].
Benefits of daily dosing of tadalafil
The daily dose keeps the medicine at a steady level in your body so that you can be ready for intimacy at any time. This is different from traditional ED tablets, which are taken only when needed [9].
Tadalafil also relaxes muscles in the prostate and bladder, making it helpful for men with urinary symptoms due to an enlarged prostate [10].
Recent research suggests that regular use of tadalafil 5mg tablets may help improve blood vessel health, reduce inflammation, and even support testosterone production—especially in men with diabetes or cardiovascular risk factors [7], [8], [12].
How to use tadalafil 5mg tablets
Take one tablet at the same time each day, with or without food. Swallow the tablet whole with a glass of water. Consistency is key—taking it daily keeps the medicine working at its best [4], [5], [11], [15].
If you miss a dose, take it as soon as you remember. If it’s almost time for your next dose, skip the missed one—never take two tablets at once. Keeping a regular routine can help you remember [4], [5], [11].
If you have questions about how to take tadalafil 5mg tablets, ask your pharmacist or prescriber for advice. Always read the patient information leaflet before starting [5].
Warnings and precautions for tadalafil 5mg tablets
Tadalafil 5mg tablets are safe and effective for most men, but they aren’t suitable for everyone. Always talk to your GP or pharmacist before starting, especially if you have ongoing health conditions or take other medication [4], [5].
You should NOT take tadalafil 5mg tablets if you:
Are allergic to tadalafil or any of the ingredients
Are taking nitrates for chest pain or heart problems
Use recreational drugs known as “poppers”
Have serious heart or liver problems
Have recently had a stroke or heart attack
Have low blood pressure or uncontrolled high blood pressure
Have rare eye diseases or a history of vision loss due to PDE5 inhibitors
Are advised by your doctor to avoid sexual activity due to cardiovascular risk
Tadalafil should be used with caution if you have mild-to-moderate liver or kidney problems, certain blood cell disorders, or if you take other medicines that might interact (like alpha-blockers) [4], [5].
If you ever experience chest pain, sudden vision or hearing loss, or an erection lasting more than four hours, seek medical help straight away [4], [5].
Side effects of tadalafil 5mg tablets
Like all medicines, tadalafil 5mg tablets can cause side effects, but not everyone will experience them. Most men find that any side effects are mild and manageable, and often disappear as their bodies get used to the medication [4], [5].
Common side effects include headache, indigestion, back pain, muscle aches, flushing, and nasal congestion. These are usually short-lived and improve as your body adjusts [4], [5].
Less common side effects include dizziness, blurred vision, palpitations, or allergic reactions. If you notice these or have any concerns, speak to your doctor or pharmacist [4], [5].
Serious side effects are rare, but if you experience chest pain, sudden loss of vision or hearing, or an erection lasting more than four hours, stop taking the tablets and seek urgent medical help [4], [5].
Common side effects of tadalafil 5mg tablets
The most frequently reported side effects of tadalafil 5mg tablets include [5]:
Headache – This is the most common complaint and usually mild. It can often be managed by drinking more water and taking the tablet with food if you’re sensitive.
Indigestion or upset stomach – You might notice bloating, mild nausea, or stomach discomfort. Avoiding heavy, fatty meals and staying hydrated can help reduce these symptoms.
Back pain and muscle aches – Some men notice mild aches in the lower back, legs, or arms, often 12–24 hours after taking tadalafil. These usually fade within a day or two and can be eased with gentle stretching or over-the-counter pain relief if needed.
Flushing (a warm, red feeling in your face or neck) – This is generally harmless and temporary.
Nasal congestion – Some people report a stuffy or runny nose.
These side effects are usually short-lived and often improve as your body adjusts to the medicine. If they persist or become bothersome, speak to your pharmacist or prescriber for advice.
Less common and rare side effects
While most men tolerate tadalafil very well, some may experience less common side effects [5], such as:
Dizziness or light-headedness – Especially when standing up quickly. If this happens, sit or lie down until it passes.
Blurred vision or changes in colour vision – Rare, but always mention any changes in eyesight to your doctor.
Palpitations or irregular heartbeat – Rare, but should be reported to your healthcare provider.
Rash or allergic reactions – Signs include itching, swelling, or difficulty breathing. If you notice these, stop taking tadalafil and seek immediate medical attention
When to seek urgent medical help
Very rarely, tadalafil can cause serious side effects [5]. Stop taking the tablets and get medical help right away if you experience:
Chest pain or severe dizziness – This could be a sign of a heart problem.
Sudden loss of vision or hearing – This is extremely rare but requires immediate attention.
An erection lasting more than four hours (priapism) – This is a medical emergency and needs prompt treatment to prevent permanent damage.
If you’re ever unsure about a side effect, don’t hesitate to contact your pharmacist, GP, or NHS 111 for advice. It’s always better to ask, even for mild symptoms, especially if they’re new or worrying.
Drug interactions with tadalafil 5mg tablets
Tadalafil 5mg tablets can interact with a variety of medicines and supplements, sometimes leading to serious side effects or reducing how well the medicine works. That’s why it’s so important to give your GP or pharmacist a complete list of everything you take—including prescriptions, over-the-counter medicines, herbal products, and supplements—before starting tadalafil [4], [5].
Medicines you must not take with tadalafil
Some drugs are absolute “no-go’s” with tadalafil because of the risk of dangerous drops in blood pressure or other severe reactions. These include [4], [5]:
Nitrates (for chest pain/angina): e.g., glyceryl trinitrate, isosorbide mononitrate, isosorbide dinitrate, and GTN sprays or patches. Taking tadalafil with any of these can cause a sudden, severe fall in blood pressure, which can be life-threatening.
Recreational drugs called “poppers” (amyl nitrate or butyl nitrate): These also act as vasodilators and can dangerously lower your blood pressure when combined with tadalafil.
Guanylate cyclase stimulators (e.g., riociguat, used for pulmonary hypertension): This combination can also cause unsafe drops in blood pressure.
Medicines that may require extra monitoring or dose changes
Tadalafil can interact with several other common medicines. Your doctor may need to adjust your dose or monitor you more closely if you take [4], [5]:
Alpha-blockers (for high blood pressure or prostate issues): e.g., doxazosin, tamsulosin, alfuzosin. Combining these with tadalafil can sometimes cause dizziness or fainting due to low blood pressure.
Blood pressure medicines (antihypertensives): e.g., ACE inhibitors, beta blockers, calcium channel blockers. Tadalafil can enhance their effects, so your prescriber may want to monitor your blood pressure more closely.
Certain antifungals: e.g., ketoconazole, itraconazole—these can increase tadalafil levels in your body, raising the risk of side effects.
Certain antibiotics: e.g., erythromycin, clarithromycin—these can also raise tadalafil levels.
HIV protease inhibitors: e.g., ritonavir, saquinavir—these can significantly increase tadalafil concentrations, so your doctor may lower your dose or recommend an alternative.
Other medicines for erectile dysfunction: Never combine tadalafil with other PDE5 inhibitors (like sildenafil or vardenafil), as this increases the risk of side effects without improving results.
Herbal remedies, supplements, and other considerations
Grapefruit and grapefruit juice may affect how your body processes tadalafil, potentially increasing side effects. It’s best to avoid grapefruit while using this medicine.
St John’s Wort (a herbal remedy for low mood) may reduce tadalafil’s effectiveness.
Other supplements or over-the-counter remedies: Always check with your pharmacist, as even “natural” products can interact with prescription medicines.
If you are ever prescribed a new medicine—whether for a short illness or long-term condition—always mention you are taking tadalafil. Likewise, if you want to try a new supplement or herbal product, check with your pharmacist first.
Final tips
Always keep an up-to-date list of your medicines and share it with every healthcare professional you see.
Never stop or start a medicine without checking with your doctor or pharmacist.
If you notice new symptoms after starting a new medicine with tadalafil, seek advice promptly.
