Not all men benefit
Although these medications can help many people, not all men can or should take them to treat erectile dysfunction. If you’ve had a heart attack, stroke or life-threatening heart rhythm during the last six months, don’t take these medications. If you’ve been told that sexual activity could trigger a cardiac event, discuss other options with your doctor. In addition, don’t take Viagra, Levitra or Cialis with nitrate medications, such as the heart drugs nitroglycerin (Nitro-Bid, others), isosorbide mononitrate (Imdur) and isosorbide dinitrate (Isordil). The combination of these medications, which work to widen (dilate) blood vessels, can cause dizziness, low blood pressure, and circulation and heart problems.
