Headache is the most commonly reported side effect of VIAGRA. But how common is it? In clinical studies, headaches were reported by 16% of men with ED who took VIAGRA—compared to 4% who took sugar pills. And, generally, the headaches were mild to moderate in nature.
Other most common side effects are flushing of the face and upset stomach.
Temporary changes in color vision (such as trouble telling the difference between blue and green objects or having a blue color tinge to them), eyes being more sensitive to light, or blurred vision.
Sudden decrease or loss of vision in one or both eyes. If you experience sudden decrease or loss of vision, stop taking PDE5 inhibitors, including VIAGRA, and call a doctor right away.
An erection that lasts many hours.
You should call a doctor immediately if you ever have an erection that lasts more than 4 hours. If not treated right away, permanent damage to your penis could occur.
Sudden loss or decrease in hearing, sometimes with ringing in the ears and dizziness. It is not possible to determine whether these events are related directly to the PDE5 inhibitors, to other diseases or medications, to other factors, or to a combination of factors. If you experience these symptoms, stop taking VIAGRA and contact a doctor right away.
Heart attack, stroke, irregular heart beats, and death. Most, but not all, of these men had heart problems before taking this medicine. It is not possible to determine whether these events were directly related to VIAGRA.
VIAGRA may cause other side effects besides those listed here. If you want more information or develop any side effects or symptoms you are concerned about, call your doctor.
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 ED treatments. VIAGRA should not be used with REVATIO or other products containing sildenafil.
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.
Talk to your doctor.
Discuss your general health and ED symptoms with your doctor to see if VIAGRA is right for you.
