Precautions While Using Viagra

Sildenafil has not been studied with other medicines used for treatment of erectile dysfunction. Presently, using them together is not recommended .

It is important that you tell all of your healthcare providers that you take sildenafil . If you need emergency medical care for a heart problem, it is important that your healthcare provider knows when you last took sildenafil.

Use sildenafil exactly as directed by your doctor . Do not use more of it and do not use it more often than your doctor ordered. If too much is used, the chance of side effects is increased.

If you experience a prolonged or painful erection for 4 hours or more, contact your doctor immediately. This condition may require prompt medical treatment to prevent tissue damage of the penis and possible permanent impotence.

This medicine does not protect you against sexually transmitted diseases. Use protective measures and ask your doctor if you have any questions about this.

It is important to tell your doctor about any heart problems you may have now or may have had in the past. This medicine can cause serious side effects in patients with heart problems.

If you experience sudden loss of vision in one or both eyes, stop using sildenafil and contact your doctor immediately.
