What starting dose of Levothyroxine is recommended for patients with known CAD?

12.5-25 mcg daily
50 mcg daily
75 mcg daily
100 mcg daily

The correct answer is: 12.5-25 mcg daily

Levothyroxine is a medication used to treat an underactive thyroid gland. It is important to note that patients with known coronary artery disease (CAD) may have an increased risk of cardiovascular events with starting levothyroxine. Therefore, the starting dose is typically lower for these patients, in order to minimize potential adverse effects. Options B, C, and D are higher doses that may increase the risk of adverse cardiovascular events for patients with CAD. Option A, with a dose range of 12.5-25 mcg daily, is recommended as a safer starting dose for these patients.
