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).

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.
