  • Watch out for Interactions Between Drugs for Erectile Dysfunction and Other Medications [hide all summaries]
    (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. 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.
  • 29 Medications That May Cause Adverse Interactions with Thyroid Drugs [hide all summaries]
    (September 2008)
    Thyroid medications are among the most widely-prescribed drugs in the U.S. In this article, we review 29 different medications that can have harmful interactions with thyroid medicines such as levothyroxine (Synthroid). There are four major kinds of interaction problems that can occur: • Certain medications can decrease the absorption of levothyroxine resulting in lower levels in the blood. • Other medications can increase the rate at which the body gets rid of levothyroxine, also resulting in lower thyroid levels in the blood. • Other medications can cause changes of levothyroxine binding in blood, decreasing the body's ability to use levothyroxine. • Levothyroxine can affect the safety or effectiveness of other medications by raising or lowering the levels of these other drugs in the blood, causing them to be either infective (lower levels) or dangerous (higher levels).
