To step

Method 1 of 3: Decide whether to take Viagra

1. Talk to your doctor. You may be a good candidate for Viagra (sildenafil) if you experience erectile dysfunction or are unable to maintain an erection long enough to have sexual intercourse. It is important to discuss this medication with a doctor to make sure it is a safe choice for you.
   • Tell your doctor if you are allergic to any medications so he or she can decide if you might be allergic to Viagra.
   • Let your doctor know about any other medications you are taking, including dietary supplements.
2. Do not take Viagra if you are taking nitrates. Nitroglycerin and other long-acting nitrates used for chest pain can cause problems when taken with Viagra, including a severe drop in blood pressure that could lead to a heart attack or stroke.
3. Do not take Viagra if you are taking alpha inhibitors. These drugs, which are prescribed for blood pressure and prostate problems, can also cause blood pressure to drop too much when taken with Viagra.

Method 2 of 3: Taking Viagra to enhance the sex experience

1. Take Viagra pills orally as directed by your doctor or pharmacist. The usual recommended dose is 50 mg, but in some cases your doctor may recommend taking a slightly larger or smaller dose.
   • Viagra pills come in 25mg, 50mg, or 100mg tablets.
   • The maximum recommended dose is 100 mg. So do not take more than 100 mg at a time.
2. Take Viagra 30 to 60 minutes before sex. Viagra is most effective when taken during this time as it takes a while for the drug to circulate and stimulate an erection. However, Viagra can be taken up to 4 hours before sex and still be effective.
3. Do not take Viagra more than once a day. Taking Viagra several times a day is not recommended, especially if you exceed the maximum dose of 100 mg.
4. Eat low-fat meals before taking Viagra. A meal that contains a lot of fat will delay the effect of Viagra. Eat light meals throughout the day before taking Viagra and avoid heavy meals with red meat, fried foods and other foods that are high in fat.

Method 3 of 3: Watch out for side effects

1. Be aware that moderate side effects can occur. Some people experience moderate side effects after taking a dose of Viagra. This does not mean that it is necessary to see a doctor, but if you experience these side effects it may be better to reduce the dose or to stop taking Viagra. Moderate side effects of Viagra include:
   • Redness and warmth in the neck and face
   • Headache
   • Stuffy nose
   • Memory problems
   • Upset stomach or back pain
2. If you experience serious side effects, see a doctor immediately. In some rare cases, Viagra can cause side effects serious enough to warrant a visit to the doctor. If you experience any of the following symptoms, stop taking Viagra immediately and contact your doctor:
   • An erection that is painful or lasts 4 hours or more
   • Loss of vision
   • Chest pain
   • Irregular heartbeat
   • Dizziness
   • Swelling in the hands, ankles, or feet
   • Nausea or a general feeling of discomfort
