Potential VIAGRA Side Effects

Safety is important. And VIAGRA has an established safety record of more than 10 years. But it helps to know about potential side effects.

The most common VIAGRA side effects are:

• Headache
• Facial flushing
• Upset stomach

Less commonly, bluish vision, blurred vision, or sensitivity to light may briefly occur.

In rare instances, men taking PDE5 inhibitors (oral erectile dysfunction medicines, including VIAGRA) reported a sudden decrease or loss of vision. 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.

In the rare event of an erection lasting more than 4 hours—also known as priapism—seek immediate medical help to avoid long-term injury. Learn more about priapism and VIAGRA.

Sudden decrease or loss of hearing has been rarely reported in people taking PDE5 inhibitors, including VIAGRA. It is not possible to determine whether these events are related directly to the PDE5 inhibitors or to other factors. If you experience sudden decrease or loss of hearing, stop taking VIAGRA and contact a doctor right away.

Other important information:

VIAGRA can help most men with ED. But it's not right for everyone. Here are some other things you should know:

Some men shouldn't take VIAGRA.

Do not take VIAGRA if you take nitrates, often prescribed for chest pain, as this may cause a sudden, unsafe drop in blood pressure.

Discuss your general health status with your doctor to ensure that you are healthy enough to engage in sexual activity. If you experience chest pain, nausea, or any other discomforts during sex, seek immediate medical help.

VIAGRA should not be used with other treatments that cause erections. VIAGRA should not be used with REVATIO as REVATIO contains sildenafil, the same medicine found in VIAGRA.

Some men should take a lower dose of VIAGRA.

If you are older than age 65, or have serious liver or kidney problems, your doctor may start you at the lowest dose (25 mg) of VIAGRA. If you are taking protease inhibitors, such as for the treatment of HIV, your doctor may recommend a 25 mg dose and may limit you to a maximum single dose of 25 mg of VIAGRA in a 48-hour period.

If you have prostate problems or high blood pressure for which you take medicines called alpha blockers, your doctor may start you on a lower dose of VIAGRA.

VIAGRA does not prevent against sexually transmitted diseases, including HIV.

VIAGRA has been shown to safely treat ED in men who have certain other health conditions.

These conditions include:

• High blood pressure
• Heart disease
• Diabetes
• Depression
• Spinal cord injury

Talk to your doctor.

Discuss your general health. Your ED symptoms. And work with him to see if VIAGRA is right for you.
