Tadalafil helps treat erection difficulties by relaxing blood vessels in the penis, allowing stronger blood flow during sexual arousal. It belongs to the same group of medicines as sildenafil but lasts much longer in the body. Many men find tadalafil helpful when they want flexibility in timing or prefer a medicine with a longer window of effect.

Tadalafil usually starts working within about 30 minutes, and its effects can last for up to 36 hours. This longer duration allows more flexibility around sex and reduces the need for exact timing. It does not cause constant erections; sexual arousal is still needed for it to work.

Daily tadalafil is taken at a low dose every day to allow more spontaneity, while on-demand tadalafil is taken before sex at higher strengths. Both options work well, and the choice depends on how often you have sex, how predictable your routine is, and whether you prefer flexibility or timing a single dose.

Tadalafil is effective for many men, including those with diabetes or prostate-related issues, and often works even when other ED medicines haven’t helped. Its long duration makes it popular for couples who prefer spontaneity. If results are mixed, a prescriber can review dose, timing or alternative ED options based on your symptoms.

Common side effects include headache, flushing, indigestion, a blocked nose and muscle aches. These usually settle as the medicine wears off. Some men notice back pain due to the way tadalafil affects blood vessels. If symptoms are severe or last longer than expected, speak to a clinician for advice on dose or alternative treatments.

Tadalafil is unsuitable for men taking nitrates, those with serious heart or liver problems, very low blood pressure, or recent stroke or heart attack. Some eye conditions and certain heart medicines also make tadalafil unsafe. A prescriber will assess your health and medicines to confirm suitability.

Yes. All tadalafil strengths, including daily and on-demand versions, require a prescription in the UK. A clinician will check your symptoms, health conditions and medication history to ensure tadalafil is safe and that the chosen dose matches your needs.

Many men prefer tadalafil because it lasts much longer (up to 36 hours) which gives more flexibility and reduces pressure around timing. It can also be taken daily at a lower dose for regular spontaneity. Some men find tadalafil causes fewer side effects than sildenafil, while others choose it because it better matches their lifestyle or sexual routine.

Yes. Tadalafil has a long half-life, meaning it stays active in the body far longer than sildenafil or vardenafil. This doesn’t mean erections last for 36 hours, it simply provides a longer window for the medicine to work when you are sexually aroused. Many men appreciate this extended flexibility.

Some men find that daily tadalafil helps improve confidence, reduces anxiety around performance and creates more consistent results. The regular low dose also avoids timing pressures. While it doesn’t “cure” ED, it often improves sexual function by supporting better blood flow and reducing the stop-start pattern of on-demand use.

Yes. Tadalafil is also licensed for treating benign prostate enlargement (BPH), as it can help relax muscles in the bladder and prostate. Men with urinary symptoms sometimes benefit from tadalafil for both erection difficulties and lower urinary tract symptoms. A prescriber will check if this dual benefit is suitable for you.

Tadalafil works the same whether it is taken with or without food, making it more flexible than sildenafil. Moderate alcohol is usually safe, but drinking heavily can make erections harder and increase dizziness or low blood pressure. Keeping alcohol intake low helps tadalafil work more consistently.

Yes. Tadalafil’s long duration and steady effect make it ideal for men who prefer flexibility rather than timing a tablet close to sex. Daily tadalafil offers even more spontaneity, removing the need to plan ahead. Many couples choose tadalafil for this reason, especially when timing is unpredictable.

If tadalafil isn’t effective, the cause may relate to timing, arousal, underlying health problems or medication interactions. A prescriber may explore alternative PDE5 inhibitors, check for contributing conditions, or suggest lifestyle changes or further assessments. It’s important not to exceed the recommended dose.
