Known interactions between the following drugs: Carvedilol, Magan

Magnesium salicylate blocks the production of chemicals known as prostaglandins. Certain types of prostaglandins cause the muscles inside of blood vessels to relax (also referred to as "vasodilation") and promote the elimination of sodium and water by the kidneys, both of which lead to a decrease in blood pressure. Although it does not seem to directly alter the blood pressure-lowering ability of carvedilol, magnesium salicylate may lessen the overall benefit of using carvedilol because of its effect on the prostaglandins. Your doctor may want to monitor your blood pressure if magnesium salicylate and carvedilol are taken together on a regular basis. If you are experiencing problems, your doctor may consider adjusting the dose of magnesium salicylate. Discuss this potential interaction with your healthcare provider at your next appointment, or sooner if you think you are having problems.
