Viagra side effects
Like all other medications, Viagra is able to cause some side effects. These side effects are usually mild to moderate and normally don’t last longer than a few hours. Some of these side effects are more likely to occur when you use the higher doses. The most common side effects of Viagra are headache, flushing of the face, and upset stomach. Less common side effects that may occur are 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.
In rare instances, there have been reported erections lasting 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, your penis could suffer permanent damage.
Heart attack, stroke, irregular heart beats, and death have been reported rarely in men taking Viagra. 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 on this sheet. If you want more information or develop any side effects or symptoms you are concerned about, call your doctor immediately.
Accidental Overdose
In case of accidental overdose, do not lose any time and call your doctor right away.
