- INTERACTIONS
-
- Liothyronine interacts with several other types of medications:
- 1. It can increase the effects of oral anticoagulants (blood thinners,
- such as warfarin), which can lead to bleeding complications.
- 2. The dosage of digoxin, insulin, or oral antidiabetic medicines may
- require adjustment when liothyronine is started.
- 3. Cholestyramine decreases the absorption of liothyronine from the
- gastrointestinal tract. Therefore, at least four to five hours should
- separate doses of these medications.
- 4. Liothyronine may increase the side effects of tricyclic
- antidepressants.
- Before starting to take this medication, BE SURE TO TELL YOUR DOCTOR
- about any medications you are currently taking, especially any of those listed
