Take one tablet one hour before sex. Viagra works best when taken on an empty stomach. Positive effects can last between four to six hours.
Never take more than one tablet within a 24 hour period. Avoid taking Viagra with more than one or two units of alcohol as alcohol can limit its effectiveness.
How it works
It works by increasing blood flow into the erectile tissue of the penis. Viagra does not have an effect on your sexual desire, but will improve your erection if you are sexually aroused.
The majority of men will notice a firmer and longer-lasting erection. If you find that the treatment does not work, ask our doctors whether it would be appropriate to increase the dose or to try a different medicine.
If Viagra doesn’t work for you first time round, it could nevertheless be more effective next time. Indeed, doctors advise trying all erectile dysfunction medicines eight times before giving up.
Side effects are uncommon, but can include nausea, vomiting, diarrhoea and an allergic rash. They can also cause facial flushing, headaches, light headedness, nasal congestion, indigestion, a pounding heartbeat and blurred vision.
Nitrates and Viagra
Our doctors will not be able to prescribe Viagra if you are taking nicorandil or nitrates, such as GTN spray or isosorbide mononitrate tablets to treat angina.
Alpha-blockers and Viagra
If you are taking alpha-blockers, our doctors will advise that you leave at least six hours between taking your alpha-blocker and taking Viagra.
