Consumer:Talk to your doctor before using levothyroxine together with pseudoephedrine. Combining these medications may increase the risk of cardiovascular side effects such as high blood pressure, palpitation, chest pain, and irregular heart beat. If you have preexisting heart disease, your condition may worsen. You may need a dose adjustment or more frequent monitoring by your doctor to safely use both medications. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.
Professional:MONITOR: The concomitant use of thyroid hormones, especially large doses, with sympathomimetic drugs may potentiate sympathomimetic effects and increase the risk of cardiac insufficiency in patients who have coronary artery disease.
MANAGEMENT: Monitoring for increased sympathomimetic effects and cardiac function may be advisable.
