Viagra Drug Class and Mechanism

Viagra Uses

Viagra is used to treat male sexual function problems (erection problems).
Viagra comes as a tablet to take it orally. It should be taken as needed about 1 hour before sexual activity. However, Viagra can be taken anytime from 4 hours to 30 minutes before sexual activity. Viagra should not be taken more than once a day. Do not take more or less of it or take it more often than prescribed by your doctor.

Viagra Side Effects

Headache, flushing, stomach upset, nasal stuffiness, diarrhea and dizziness might occur. If these effects persist or worsen, notify your doctor promptly. Unlikely but report promptly: painful or other urination problems, vision problems, skin rash. Very unlikely but report promptly: chest pain, fainting, foot or ankle swelling. If you experience a painful or prolonged erection (lasting longer than 4 hours), stop using Viagra and seek immediate medical attention. If you notice other effects not listed above, contact your doctor or pharmacist.

Viagra Overdose

In studies with healthy volunteers of single doses up to 800 mg, adverse events were similar to those seen at lower doses but incidence rates were increased. In cases of overdose, standard supportive measures should be adopted as required. Renal dialysis is not expected to accelerate clearance as sildenafil is highly bound to plasma proteins and it is not eliminated in the urine.

Viagra More Information

If you are over 65 years of age, you may be more likely to experience side effects from Viagra. Your doctor may prescribe a lower dose of this medication.
