  • 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).
