What to know

Information to review with your prescriber or care team

These notes are educational and do not replace directions from your prescriber or the label on your prescription.

What is it?

Thyroid hormone can be compounded into capsules at strengths and combinations not available as commercial tablets. This includes a fixed combination of T4 (levothyroxine) and T3 (liothyronine) in one capsule, or T3 (liothyronine) on its own. Modified-release versions can be prepared so T3 is released more gradually.

Why compound it?

Some patients need a precise dose between commercial strengths, a specific T4-to-T3 ratio, or a capsule free of a particular filler or dye. The prescriber sets the strengths, ratio, and release type, and arranges the blood-test monitoring that thyroid therapy needs.
