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. The other 16 drugs speed up the metabolism of the ED drugs, thereby lowering the blood levels and reducing the effectiveness of the ED drugs.

There is an additional similarity (aside from our listing both as DO NOT USE drugs) between valdecoxib and celecoxib, both are sulfa drugs and individuals who are allergic to sulfa drugs should not use them. Although celecoxib came on the market with a warning about sulfa drug allergy, valdecoxib did not. We previously wrote “It may be a dangerous oversight on the part of the FDA not to have required the same warning for valdecoxib.” Unfortunately, because uninformed patients have been needlessly harmed, our prediction has come to pass.
