Liothyronine Sodium Information

Liothyronine sodium (Cytomel®) is available only by prescription and is used to treat an underactive thyroid and various types of goiters. It is also used in certain thyroid diagnostic tests. This medication is not appropriate for everyone; your healthcare provider needs complete information on your medical history and what drugs you are taking before prescribing it.
This medication comes in tablet form and is available in three different strengths. Though generally well tolerated, side effects of liothyronine sodium are possible and may include things like irritability, nervousness, and sweating.
