Who should not take a nitrate medication?

Anthony L. Komaroff, MD
Internal Medicine
Do not use nitrates if you are taking medications to treat erectile dysfunction, such as tadalafil (Cialis), vardenafil (Levitra), or sildenafil (Viagra). These medications can cause a life-threatening drop in blood pressure when used in addition to a nitrate. If you are taking nitroglycerin and are experiencing erectile dysfunction, talk with your doctor about alternative treatments.
