Factors Influencing Cytomel Dosage

  3. The maintenance dose usually ranges from 25 to 75 mcg daily, but some patients may require higher doses based on their condition.
  4. Regular monitoring of thyroid hormone levels is essential to adjust dosages accurately.

Potential Side Effects of Incorrect Dosing
