Summary
Activated charcoal can adsorb thyroid hormone analogues in the gut, reducing how much tiratricol is absorbed. This may lead to reduced efficacy.
What this interaction means in plain words
Charcoal and Tiratricol can affect each other. The combination is often manageable, but it may need a change of dose, a change of timing, or extra checks while both are taken.
Charcoal belongs to Gastrointestinal Tract; Tiratricol belongs to Endocrine.
Why it happens
Adsorption of tiratricol in the gastrointestinal lumen reduces its absorption.
What to do
Separate administration by more than 2 hours where possible, and monitor T3 and thyroid function if charcoal is used regularly.
