The best time to take Viagra (and Kamagra) for it to work

Getting the timing right is the difference between sildenafil working well and seeming not to work at all. Here's exactly when to take Viagra, Kamagra or Cenforce before intimacy, and what food, alcohol and format do to that timing.

The ideal window

The EMA product information for Viagra advises taking sildenafil about 1 hour before sexual activity. The same hour applies to oral jelly: the EU product information gives sildenafil's orodispersible form the same timing as its tablets. It then works for around four hours, so you don't need to time it to the minute — a comfortable window beforehand is ideal. Tadalafil is different, lasting up to 36 hours, so its timing is far more flexible.

Take it on a lighter stomach

Food — especially a heavy or fatty meal — delays absorption and can push onset back by about an hour on average (EMA: Viagra). A lighter stomach avoids that delay. This is the single most common timing mistake: taking it right after a big dinner and assuming it failed.

Mind the alcohol

A drink or two is usually fine, but alcohol lowers blood pressure and impairs erections, so heavy drinking around your dose works against it — see Viagra and alcohol. Time your dose for when you'll be relaxed but not heavily drinking.

It works with arousal, not on a timer

Sildenafil doesn't produce an automatic erection at the 30-minute mark — it opens a window in which arousal can. So the 'best time' is also about setting: unhurried, relaxed and genuinely aroused. Performance anxiety shortens everyone's response, medicine or not.

The rules, briefly

One dose per 24 hours; never with nitrates or poppers; medical advice for heart, liver or kidney conditions. New ED deserves a check-up. Full detail in the complete Kamagra guide and on the Cenforce 100 product page.

Common questions

How long before sex should I take Viagra?

About 1 hour before, as the EMA product information for Viagra advises — for oral jelly too. It then works for around four hours.

Should I take Viagra on an empty stomach?

A lighter stomach avoids the delay a meal causes: in the EU product information, food delayed sildenafil's absorption by about an hour on average.

What's the best time of day to take it?

Whenever suits your plans within its four-hour window — there's no 'best' hour. Just allow about an hour's lead time, a lighter stomach and minimal alcohol.

Why isn't my Viagra working when I take it?

The usual causes are a heavy meal, too much alcohol, not enough arousal, or a counterfeit product. Correct those first; if a genuine dose still fails, see a doctor.
