Cytomel (T3) is rarely prescribed on its own to address thyroid problems; it is usually prescribed with T4. In the past, cytomel was a scheduled treatment for obesity; however, an increase in heart complications and cardiac stress forced withdrawal of T3 for that application.
*Besides T4 and T3, desiccated thyroid (DT) contains other potentially active compounds. No peer-reviewed double-blind study has been performed on the benefits of DT versus synthetic T4, either alone or in combination with T3. Some informal studies indicate patient improvement when combining T4 with T3, while others do not. Anecdotal patient accounts note improvement with Acella's NP Thyroidâ¢.
