Viagra Indications & Dosage

Viagra is indicated for the treatment of male impotence (Erectile Dysfunction), a sexual disorder in which a man is unable to attain and maintain erection during sexual stimulation.

Viagra Dosage

The recommended dose of Viagra is 50mg for patients suffering from Erectile Dysfunction (ED). The drug is advised to take approximately one hour before sexual activity. However, based on effectiveness and toleration, the dose may be increased to a maximum recommended dose of 100mg or decreased to 25mg. Patients are supposed to take this drug once in 24 hours or as prescribed by their physician. This medication can be taken any time during the day; however you should not take Viagra more than once a day. It can be taken with or without food.

What is the perfect dose of Viagra?

There are a few factors that claim to increase plasma levels of Viagra (sildenafil), including age>65 (40% increase in AUC), hepatic impairment, severe renal impairment and concomitant use of potent cytochrome P450 3A4 inhibitors. Since higher plasma levels may increase both the efficacy and incidence of adverse events, a starting dose of 25mg should be considered in ED patients. If you are unsure about anything related to your proper dose of Viagra, visit your doctor or read the information at Viagra Bulk.

Viagra has shown its potentiate the hypotensive effects of nitrates and administration in patients who use nitric oxide donors or nitrates in any form is therefore contraindicated.

Moreover, the dose of Viagra above 25 mg and an alpha-blocker may lead to symptomatic hypotension in some patients. Doses of 50 mg or 100 mg of Viagra should not be taken within 4 hours of alpha-blocker administration. A 25 mg dose of Viagra may be taken at any time. But, if you meet with any difficulty, then consult your physician immediately.
