Viagra pills are taken orally with a glass of water. The average recommended dosage is 50 mg sildenafil. The appropriate pills dosage is taken one hour before sexual intercourse.

An average dose of sildenafil 50 mg can be reduced to 25 mg, and increased up to 100 mg, depending on tolerability and severity of effect. The maximum dosage should not exceed 100 mg. It should be taken in dosage of one tablet per day, one hour before planned sexual intercourse.

This tablet should contain 25 mg, 50 mg or 100 mg of active substance. Older people are taking sildenafil in the same dosages. When taken with meals the effect appears a little later in comparison to on an empty stomach application.

In the presence of a renal function, sildenafil should be adjusted to the following dosing. If glomerular filtration rate (creatinine clearance) according to Rehberg Test is from 30 to 80 ml/min, the drug is taken in regular doses that do not need to be adjusted. If CC is less than 30 ml/min, the drug should be taken at a dosage of 25 mg.

People with severe hepatic function impairment should use a 25 mg dose. If necessary, at the same time, this substance with ritonavir may be taken together at a dose of 25 mg. If you suddenly feel blurred vision or hearing loss, you should immediately stop using this drug.

Sildenafil cannot be combined with other drugs that also eliminate erectile dysfunction. In general, Sildenafil does not reduce the attention and psychomotor reactions speed, so during treatment with Sildenafil, you can drive a car.

However, you must carefully monitor your own state, because the drug can cause a decrease in pressure, blurred vision and poor color vision.
