What is Mounjaro?

  • Active Ingredient: Tirzepatide.
  • Drug Class: GIP and GLP-1 receptor agonist.
  • Indications: Type 2 diabetes in adults.
  • Administration: Subcutaneous injection once a week.
  • Available Strengths: 2.5 mg, 5 mg, 7.5 mg, 10 mg, 12.5 mg, 15 mg per 0.5 mL in single-dose

How Does Mounjaro Work?

  • Mounjaro works by activating GIP and GLP-1 receptors, natural incretin hormones that help regulate
    blood sugar levels. It helps the pancreas produce more insulin, reduces the amount of sugar the
    liver makes, and slows the rate food passes through the body, thereby making one feel full longer.

Side Effects and Warnings

  • Common Side Effects: Include nausea, diarrhea, decreased appetite, vomiting, constipation,
    dyspepsia, and abdominal pain.
  • Serious Side Effects: Can include allergic reactions, pancreatitis, stomach problems, vision
    changes, thyroid tumors, gallbladder problems, low blood sugar, and kidney problems. Immediate
    medical attention is required for serious side effects.
  • Warnings: Not suitable for people with a family history of medullary thyroid carcinoma (MTC)
    or Multiple Endocrine Neoplasia syndrome type 2 (MEN 2).

Usage Instructions

  • Dosage:Starts with a low dose and gradually increases. Should be injected once a week, with
    or without meals, in the thigh, abdomen, or upper arm. Rotate the injection site with each dose.

Special Considerations

  • Pregnancy and Breastfeeding: The effects on pregnancy and breastfeeding are not fully known.
    Additional birth control methods may be needed.

Drug Interactions and Contraindications

  • It is important to inform your healthcare provider about all the medicines you take, including
    prescription, over-the-counter medicines, vitamins, and herbal supplements. Mounjaro may interact
    with other diabetes medications, increasing the risk of hypoglycemia.
