Viagra



Viagra (Sildenafil Citrate) is used to treat male sexual function problems (erection problems) commonly known as ED (erectile dysfunction). Viagra is available in 25mg, 50mg and 100mg tablets.

How to take Viagra
Viagra is taken by mouth as needed (usually once daily) between four hours and one-half hour before sexual activity (about one hour before is most effective).

Take Viagra only as directed by your physician, pharmacist or primary care professional. Sildenafil (Viagra) works along with sexual stimulation to help achieve and maintain an erection.

Side Effects
Side effects that may occur while taking Viagra include headache, flushing, stomach upset, nasal stuffiness, diarrhea and dizziness. If these effects persist or worsen, notify your doctor promptly. Erections lasting longer than 4 hours require the immediate attention of a physician.

Drug Interactions
Before using Viagra, inform your physician of all nonprescription and prescription medication you may use, especially any 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) or high blood pressure medicines.

Precautions
Before using Viagra, tell your doctor your medical history, including any allergies (especially drug allergies), any penis conditions such as fibrosis/scarring, history of painful/prolonged erection (priapism), sickle cell anemia, blood system cancers (such as leukemia or myeloma), or Peyronie's disease, eye problems (retina diseases). kidney or liver disease, bleeding disorders or active stomach ulcers, heart diseases, stroke or severe high or low blood pressure.

Limit alcohol intake, as it may aggravate side effects of Viagra. To avoid dizziness and lightheadedness when rising from a seated or lying position, get up slowly. The elderly may be more sensitive to the side effects of Viagra.

Notes
Do not share Viagra with others, since they may have a problem that is not effectively treated by Sildenafil. The use of Viagra does not protect against sexually transmitted diseases (e.g., HIV, Hepatitis B, gonorrhea). Keep Viagra and all medications out of the reach of children.
