Drug Interactions between Cytomel and tasimelteon

Food can delay the absorption of tasimelteon, which may increase the amount of time it takes for the medication to work. You should take tasimelteon without food at the same time each night before going to bed. If you are a smoker, there is a possibility that tasimelteon may not work as well for you due to reduced blood levels of the medication in smokers compared to nonsmokers. You should avoid or limit the use of alcohol while being treated with tasimelteon. It can increase some of the side effects including dizziness, drowsiness, and difficulty concentrating. Some people may also experience impairment in thinking and judgment. Talk to your doctor or pharmacist if you have any questions or concerns.

Using multivitamin with minerals together with liothyronine may decrease the effects of liothyronine. You should separate the administration of liothyronine and multivitamin with minerals by at least 4 hours. If your doctor does prescribe these medications together, you may need a dose adjustment or special test 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.
