A compounded capsule with both thyroid hormones: T4 (levothyroxine) and T3 (liothyronine), in a fixed ratio.
Some patients' physicians prefer a combination when T4 alone does not bring their labs and symptoms where they should be. Compounded capsules are not FDA-approved.

06Safety
Important safety information
Thyroid hormones, alone or with other drugs, should not be used to treat obesity or for weight loss. In people with normal thyroid function, doses that are too high can cause serious or even life-threatening toxicity.
Too much can cause a fast or irregular heartbeat, chest pain, anxiety, trouble sleeping, heat intolerance and, over time, bone loss. Take it the same way every day, apart from calcium, iron and antacids, and keep up the labs your physician asks for.
Tell your physician about every condition and medicine before starting, and report any new symptom.
Compounded medications are prepared by state-licensed pharmacies for individual patients. They are not FDA-approved and have not been evaluated by the FDA for safety, effectiveness or quality. This page is general information and does not replace a consultation with a licensed physician, who decides whether a treatment is appropriate for you.
