Watch out for Interactions Between Drugs for Erectile Dysfunction and Other Medications
January 2009
The article lists 56 drugs that can interact with the three drugs for erectile dysfunction (ED): sildenafil (VIAGRA), tadalafil (CIALIS) and vardenafil (LEVITRA). Eight of the drugs are either nitrates such as nitroglycerin or a certain group of high blood pressure drugs.In combination with ED drugs, these drugs can cause a dangerous fall in blood pressure that could lead to a heart attack or stroke. Thirty-two other drugs can inhibit the enzyme that helps the body to eliminate the ED drugs, resulting in abnormally high blood levels of the drugs and a potentially harmful "overdose" even though you are actually taking the recommended amount.
