Viagra (sildenafil) is a drug intended for the treatment of certain conditions related to impotence, namely erectile dysfunction that can be caused by a number of factors. When taking this medicine there are a number of serious side effects you are supposed to watch for. Firstly, it’s priapism – a long and painful erection that does not go away after 4 hours. Another one is sudden vision loss that is most often experienced by people older than 50 and those diagnosed with diabetes, high cholesterol, and high blood pressure. Therefore it’s important to talk to your health care provider in advance to make sure you are not affected by one of these side effects.
Less serious side effects of Viagra include facial flushing, headache, runny or stuffy nose and some others that usually go away on their own. The symptoms of an overdose are not known but if you think you have taken too much of this medicine, contact your local emergency room as soon as possible. Although Viagra is usually well-tolerated it has been reported to have a number of serious side effects, such as bleeding in the lungs, bleeding in the brain, high blood pressure and sudden death. In most cases, however, patients that reported these health consequences had certain heart problems before the treatment.
