1. Understanding Mounjaro 2.5 mg and Its Role in Therapy

The 2.5 mg dose of Mounjaro is the starter dose, designed to:

• Minimize gastrointestinal side effects

• Allow gradual tolerance to tirzepatide

• Prepare patients for therapeutic doses (5 mg and above)

Because it is a starter dose, insurance coverage is usually tied to FDA-approved indications, such as:

• Type 2 diabetes

• Chronic weight management (depending on the plan)

Patients need to recognize that full therapeutic effects usually appear at higher doses, which are also covered by insurance.
