Talk with your doctor first. Make sure you are healthy enough to
have sex. If you have chest pain, nausea, or other discomforts during sex, seek medical help right away.The most common side
effects of VIAGRA are headache, facial flushing, and upset stomach. Less common are bluish or blurred vision, or being sensitive
to light. These may occur for a short time.
In rare instances, men taking PDE5 inhibitors (oral erectile dysfunction
medicines, including VIAGRA) reported a sudden decrease or loss of vision in one or both eyes. It is not possible to determine
whether these events are related directly to these medicines or to other factors. If you experience sudden decrease or loss
of vision, stop taking PDE5 inhibitors, including VIAGRA, and call a doctor right away.
Although erections lasting for more than four hours may occur rarely
with all ED treatments in this drug class, it is important to seek immediate medical attention. Erections lasting more than
six hours can result in long-term loss of potency.
The lowest dose of VIAGRA is 25 mg. Your doctor may start you at
this dose if any of these apply to you:
- You are age 65 or older
- You have severe liver or kidney problems
- You take protease inhibitors, drugs for HIV. If you do take them, your doctor
may also limit how often you take VIAGRA. Your doctor may tell you to take no more than 1 dose within a 2-day (48-hour) time
period
