  1. Good evening.
    Warm welcome to MediMetry.

    Viagra is used for treatment of Erectile Dysfunction (ED) and should be used only upon prescription by a registered doctor and should be completely avoided if one doesn't have ED.
    Usually side effects of Viagra may include, headache, upset stomach, diarrhea, urinary tract infection, and flushed skin, but it may also cause more harmful side effects like painful erections which last for several hours, and the lowering of blood pressure to unsafe levels if Viagra is taken with certain other drugs.
    Low blood pressure may lead to additional harmful problems such as heart attacks or strokes and can even cause vision disturbances.

    Hope this helps.

    Live healthy!
