Who qualifies for Mounjaro

Our EU-licensed doctors look for specific criteria to determine if Mounjaro is appropriate for you. Mounjaro (tirzepatide) is primarily prescribed for adults with type 2 diabetes and for chronic weight management. Typically, this involves:

  • A Body Mass Index (BMI) of 30 kg/m² or greater (obesity).
  • A BMI of 27 kg/m² or greater (overweight) with at least one weight-related comorbidity such as hypertension, dyslipidemia, or obstructive sleep apnea.

Contraindications include a personal or family history of medullary thyroid carcinoma (MTC) or Multiple Endocrine Neoplasia syndrome type 2 (MEN 2), and a history of pancreatitis. Always disclose your full medical history during the online consultation. The doctor remains the gatekeeper, ensuring your safety and the treatment's suitability.

What Mounjaro actually does (and doesn't do)

Mounjaro is a dual GIP and GLP-1 receptor agonist. This means it mimics two natural gut hormones that help regulate blood sugar and appetite. It works by:

  • Increasing insulin release when your blood sugar is high.
  • Reducing the amount of sugar your liver makes.
  • Slowing down how quickly food leaves your stomach, which helps you feel fuller longer.

You inject Mounjaro weekly. Patients often see significant weight loss and improved blood sugar control. However, Mounjaro is not a miracle cure; it works best when combined with dietary changes and increased physical activity. Realistic timelines mean gradual, steady progress, not instant results.

Side effects and when to stop

Like all medications, Mounjaro has potential side effects, most commonly gastrointestinal. Expect these to be mild to moderate and often temporary as your body adjusts:

  • Nausea, diarrhea, and constipation: These are the most frequently reported side effects.
  • Vomiting, abdominal pain, decreased appetite: Also common, especially when starting or increasing dosage.

More serious, though rare, side effects require immediate medical attention. These include severe abdominal pain (possible pancreatitis or gallbladder problems), signs of kidney issues, or allergic reactions (rash, swelling, difficulty breathing). If you experience any severe or persistent side effects, stop the medication and consult a doctor immediately via your private chat in the Hi-Doctor app.
