Ask your doctor before using liothyronine together with methIMAzole. Using these medications together may decrease the effects of liothyronine. MethIMAzole decreases thyroid hormone and may cause your body to produce too low of levels of thyroid hormone. Therefore, the use of methIMAzole and liothyronine should generally be avoided due to their opposing properties. 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.

GENERALLY AVOID: Antithyroid agents such as methimazole and propylthiouracil can affect the therapeutic response to thyroid hormone therapy. These agents decrease thyroid hormone secretion, which may result in hypothyroidism. Conversely, thyroid hormone therapy can antagonize the pharmacologic effects of antithyroid agents by supplying an exogenous source of the hormone.

MANAGEMENT: Concomitant use of antithyroid agents and thyroid hormones should generally be avoided due to mutually negating effects.
