Drug Interactions With Sibutramine

Drug interactions with sibutramine are possible if it is taken with certain other medications, such as some pain medications; cough cold, or allergy medications; and other weight-loss medications. Some of these drug interactions with sibutramine can affect the level of medications in your blood, possibly increasing your risk of side effects or decreasing the effectiveness of the medications.
