Tadalafil works for most men with erectile dysfunction — around 7 or 8 in 10 find it effective.

Take it 30–60 minutes before sex. It lasts around 4–6 hours. Sexual arousal is still needed for it to work.

Don't take it if you use nitrate medicines (e.g. GTN spray) — speak to your pharmacist or GP first if you're unsure.

Tadalafil usually starts working within 30–60 minutes.

It lasts much longer than other ED tablets — up to 36 hours — which is why it's sometimes called the "weekend pill."

Tadalafil is the generic form of Cialis. They are essentially the same treatment sold under a different name. Cialis is a well-known brand and therefore more expensive than the generic equivalent. In terms of ingredients and effectiveness, however, they are identical.

You should not take Tadalafil with other medications unless your doctor or pharmacist has told you that it is safe to do so. Sildenafil can interact with other medications, especially nitrates used in the treatment of chest pains and may result in a dangerously low drop in blood pressure.

If Tadalafil doesn't work for you the first time it may be because:

• you have not waited long enough for it to get to work before attempting to have see
• you have waited too long after taking it
• the dose was not high enough for your needs
• you were not sufficiently sexually aroused

States of anxiety and stress can prevent sexual arousal and may therefore make Tadalafil less effective. It is still important to be aroused and as relaxed as possible

No. There is no clear evidence stating that Tadalafil affects the fertility of men who take it.

Tadalafil is safe to take in the long term. There is no evidence to suggest that taking Tadalafil in accordance with dosage guidelines has any negative effects over the span of many months or even years.

The different strengths of Tadalafil Once daily tablets (2.5mg, 5mg) refer to the amount of the active ingredient present in each tablet. 2.5mg is a common starting dose for most men with ED, and this may be increased depending on your needs.

There are several alternatives to Tadalafil ranging from alternative medications to non-medical alternatives.

Medical alternatives include the generic medications Sildenafil (often sold under the brand name Viagra) and Vardenafil (often sold under the brand name (Levitra).

These are also PDE5 inhibitors and work in the same ways.

Other non-medical alternatives include penis pumps that use suction to draw blood flow to the penis, or penile rings that inhibit the flow of blood away from the penis for longer-lasting erections.
