What is Viagra® used for?

Viagra® is used to treat impotence in men. Viagra® increases the body’s ability to achieve and maintain an erection during sexual stimulation. Viagra® does not protect you from getting sexually transmitted diseases, including HIV.

Who should not take Viagra®?

Men who are currently using medicines that contain nitrates, such as nitroglycerin should not use Viagra® because taken together they can lower the blood pressure too much. Viagra® should not be used by women or children.

General Precautions with Viagra®:

• You should have a complete medical history and exam to determine the cause of your impotence before taking Viagra®.
• Men who have medical conditions that may cause a sustained erection such as sickle cell anemia, leukemia or multiple myeloma or who have an abnormally shaped penis may not be able to take Viagra®.
• There are several medications that are known to interact with Viagra®, so be sure to tell your doctor about all medications you are taking including those you can get without a prescription.
• Viagra® has not been studied with other treatments for impotence, so use in combination with other treatments is not recommended.

How should I take Viagra®? Your healthcare provider may prescribe Viagra® as one tablet once a day, about 1 hour before sexual activity. However, Viagra® may be taken anywhere from 30 minutes to 4 hours before sexual activity.
