Viagra - what kind of medicine is it?

Viagra is the trade name of a prescription only medicine whose scientific name is sildenafil citrate. Viagra is one of a class of medicines known as PDE-5 (Phosphodiesterase type 5) inhibitors. The other two medicines in this class are Cialis (tadalafil) and Levitra (vardenafil).

Our online doctors are able to offer Viagra as part of our online impotence treatment service.

Viagra - how does it work?

Viagra and the other PDE-5 inhibitors can help men with impotence (erectile dysfunction) by increasing the blood flow into the erectile tissue in the penis when a man is aroused.

Viagra - is it an aphrodisiac?

Viagra is not an aphrodisiac because it can only work if a man is already sexually aroused. Viagra will not create any sense of arousal itself.

Viagra - how effective is it?

Viagra has been shown to be effective at helping some men attain and sustain better erections. How a particular man responds to Viagra, Cialis and Levitra very much depends upon the underlying cause of his impotence, the severity of any underlying cause and his degree of sexual stimulation.

Viagra – how quickly does it work?

On average, Viagra becomes effective in just under an hour when you take a Viagra tablet on an empty stomach. Viagra can remain effective for between four and five hours. This does not mean that your erection will last that long - simply that you will have the ability to attain an improved erection for that period of time. If you take Viagra after a meal that has a high fat content, Viagra may take longer than an hour to become effective.

Viagra - are there any side-effects?

Like all medicines, Viagra can have side-effects. Thankfully, Viagra's side-effects are generally mild and brief. Viagra's common side-effects are headache and facial flushing. Less frequently, men taking Viagra have reported indigestion, a stuffy nose and a blue tint to the vision.

Viagra – will it affect my blood pressure?

Viagra can lower blood pressure. This is not a problem for most men, but Viagra's effect on blood pressure can be dangerous if you take Viagra at the same time as taking a medicine that contains nitrates. Nitrates are one of the medicines that doctors regularly prescribe for angina. If you take Viagra at the same time as taking nitrates, the interaction of the two medicines can cause your blood pressure to fall to a dangerously low - even fatal - level.

Viagra – if I have a heart condition can I take it?

A doctor would need to advise you on whether Viagra is suitable in your situation. But if you have a heart condition where sexual activity is not advised, it would not be appropriate for you to take Viagra. Your doctor would also need to advise you on whether any medicines you are taking could react with the Viagra.

Viagra – are there different doses?

Viagra is available in three dosages: 25mg, 50mg and 100mg. A doctor always advise you on which dose to take. Some men may respond to a lower dose of Viagra. Other men may already be taking medicines that interact with the Viagra, in which case a doctor will adjust your dosage accordingly.

Viagra - does it treat the underlying causes of impotence?

Viagra will not resolve any underlying physical cause of male impotence. Hence, any man complaining of impotence must be investigated for possible underlying causes of the condition. But if the cause of your impotence is primarily psychological, it may help to break the cycle of anxiety and failure associated with being unable to achieve a satisfactory erection.

Viagra – can women take it?
