My doctor: WHAT SIDE EFFECTS CAN VIAGRA CAUSE?

Headache, flushing, stomach upset, heartburn, nasal stuffiness, diarrhea, dizziness, or lightheadedness may occur.
Vision changes such as increased sensitivity to light, blurred vision, or impaired blue/green color discrimination may
also occur. If any of these effects persist or worsen, notify your doctor or pharmacist promptly.
Remember that your doctor has prescribed this medication because the benefit to you is greater than the risk of side
effects. Many people using this medication do not have serious side effects.
Rarely, a sudden loss of eyesight in one or both eyes (NAION) may occur. This may or may not be due to sildenafil. If
this serious problem occurs, seek immediate medical attention. You have a slightly greater chance of developing this
serious eye problem if you have heart disease, diabetes, high cholesterol, certain eye problems ("crowded disk"),
high blood pressure, are over 50 years of age, or if you smoke.
Sexual activity may put extra strain on your heart, especially if you have heart problems. If you have heart problems
and experience any of these serious side effects while having sex, stop and tell your doctor immediately of: severe
dizziness, fainting, chest pain, nausea.
For males, in the very unlikely event you have a painful or prolonged erection lasting 4 or more hours, stop using this
drug and seek immediate medical attention, or permanent problems could occur.
A serious allergic reaction to this drug is unlikely, but seek immediate medical attention if it occurs. Symptoms of a
serious allergic reaction include: rash, itching, unusual swelling, severe dizziness, trouble breathing.
This is not a complete list of possible side effects. If you notice other effects not listed above, contact your doctor or
pharmacist.

WHAT SHOULD I DO IN THE EVENT OF AN OVERDOSE?

If overdose is suspected, contact your local poison control center, US National Poison Hotline at 1-800-222-1222, or
emergency room immediately.
Symptoms of overdose may include severe dizziness, fainting, or prolonged erection.
