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.

Dosage

The recommended dose of Viagra is 50mg for patients. Basically, it is taken as needed. It is supposed to be taken 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 the physician. This medication can be taken any time during the day; however you should not take Viagra more than once a day. You can take Viagra with or without food.

There are few factors associated with increased 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 these patients.
