Viagra (sildenafil citrate) is a prescription medicine used to treat erectile dysfunction in male patients. It is not intended to be used in women. Viagra works by blocking an enzyme PDE5. By blocking PDE5 Viagra prevents muscle construction in the penis not allowing the blood to escape back into the body. As a result the erection is firmer than usually and can be maintained for longer. This drug can be taken with some food or without, but you are not supposed to eat fatty foods while taking Viagra as this can decrease its effects. You need to be aware of the fact that some health conditions can render your treatment inefficient or change the effects of Viagra, which is why it's recommended to talk to your doctor before taking this pill for the first time. Even if you have taken this medicine before your dosage may need to be reconsidered later depending on a number of factors your doctor considers important.

People with heart disease risk factors should be especially careful when taking Viagra as they can experience serious health problems, such as a stroke, heart attack and even sudden death. A rare but potentially dangerous side effect of Viagra that has been reported by just a few patients is a prolonged erection that causes pain and does not go away after 4 hours. Seek emergency help if you think this is the case to avoid damage to your penis tissues. According to the numerous studies only 1 of 40 patients taking this drug had to stop the treatment completely because of the side effects, with some people benefitting from Viagra after their initial dosage has been adjusted. In some rare cases patients reported diarrhea, dizziness, skin rash and vision problems (generally described as an inability to tell the difference between blue and green or some objects having blue tinge to them).
