notify your doctor immediately.
Unlikely symptoms, but report to a physician promptly: painful urination or
other urinary problems, vision problems, skin rash.
Very unlikely symptoms, but report to a physician promptly: chest pain, fainting, foot or ankle swelling.
If you

stop using Viagra and seek immediate medical attention. If you notice effects not listed above, contact your doctor or pharmacist immediately.
Viagra is taken orally, as needed, between four
hours and one-half hour before sexual activity (about one hour before is
most effective). Take only as directed, usually once daily as needed. Sildenafil works along with sexual stimulation to help achieve an
erection.
Viagra is used to treat male sexual function problems (erection problems).
Before using Viagra, inform your doctor about 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 Viagra. 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 ingested by women or children.
The elderly may be more sensitive to side effects of the drug,
therefore caution is advised for seniors.
Inform your doctor about all non-prescription and prescription
medication you are using, especially 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, and certain HIV protease inhibitors (such as
saquinavir, ritonavir, amprenavir). Do not begin or end any medicinal treatments or usage
without a doctor's or pharmacist's approval.
If overdose is suspected, contact your local poison control
center or emergency room immediately. Symptoms of overdose may include
severe dizziness, fainting, or prolonged erection.
Do not share Viagra, as other persons may have
problems not effectively treated by Viagra. Use of Viagra does not
protect against sexually transmitted diseases (e.g., HIV, Hepatitis B,
gonorrhea).
Not applicable.
