ViagraDrug Name: VIAGRA

SILDENAFIL - ORAL (sill-DEN-uh-fil)

COMMON VIAGRA BRAND NAME(S): Viagra

VIAGRA USES: Viagra is used to treat male sexual function problems (erection problems).

HOW TO USE VIAGRA: Viagra is taken by mouth as needed between four hours and one-half hour before sexual activity (about one hour before is most effective). Take Viagra only as directed, usually once daily as needed. Viagra (Sildenafil) works along with sexual stimulation to help achieve an erection.

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 from Viagra not listed above, contact your doctor or pharmacist.

VIAGRA PRECAUTIONS: Before using Viagra, tell your doctor your medical history, including: allergies (especially drug allergies), penis conditions such as fibrosis/scarring (e.g., Peyronie's disease), history of painful/prolonged erection (priapism), sickle cell anemia, blood system cancers (such as leukemia or myeloma), eye problems (retina diseases), kidney or liver disease, bleeding disorders, active stomach ulcers, heart disease, stroke, very high or low blood pressure. Limit alcohol intake, as it may aggravate side effects of this drug. Since Viagra may cause dizziness, caution is advised when performing tasks requiring alertness (e.g., driving). To avoid dizziness and lightheadedness when rising from a seated or lying position, get up slowly. Viagra is not to be used in women or children. The elderly may be more sensitive to the side effects of this drug, therefore caution is advised in this group.

VIAGRA DRUG INTERACTIONS: Tell your doctor of all nonprescription and prescription medication you may use, especially of: nitrate medications (e.g., nitroglycerin, isosorbide dinitrate), nitroprusside (any "nitric oxide donor" medicines), cimetidine, erythromycin, azole antifungals (e.g., itraconazole, ketoconazole), mibefradil, rifamycins (e.g., rifampin), high blood pressure medicines, certain HIV protease inhibitors (such as saquinavir, ritonavir, amprenavir). Do not start or stop Viagra or any medicine without doctor or pharmacist approval.

VIAGRA OVERDOSE: If Viagra overdose is suspected, contact your local poison control center or emergency room immediately. Symptoms of Viagra overdose may include severe dizziness, fainting, or prolonged erection.

VIAGRA NOTES: Do not share Viagra with others, since they may have a problem that is not effectively treated by Viagra. Use of Viagra does not protect against sexually transmitted diseases (e.g., HIV, Hepatitis B, gonorrhea).

MISSED VIAGRA DOSE: Not applicable. VIAGRA STORAGE: Store Viagra at room temperature between 59 and 86 degrees F (15-30 degrees C) away from light and moisture.

What Nitrates Interact with Viagra

I wanted to know exactly which nitrates interact with Viagra. Thanks for any help. Mike

These Nitrates will interact with Viagra

Sildenafil can cause hypotension (abnormally low blood pressure that can lead to fainting and even shock) when given to patients who are taking nitrates. Therefore, patients taking nitrates daily, even patients taking nitrates only once a day, should not take sildenafil. Nitrates are used most commonly to relieve angina (chest pain due to insufficient blood supply to the heart muscle because of narrowing of the coronary arteries); these include nitroglycerine tablets, patches, ointments, sprays, and pastes, as well as isosorbide dinitrate, and isosorbide mononitrate. Other nitrates such as amyl nitrate and butyl nitrate also are found in some recreational drugs called "poppers".
