Mounjaro explained

Mounjaro is a brand of tirzepatide used for type 2 diabetes and, in many countries, for weight management in adults with obesity or overweight with related health problems. It is a long-term medical treatment and is not a cosmetic product.


How Mounjaro works

Tirzepatide copies two gut hormones, GLP-1 and GIP, which increase fullness, slow stomach emptying and help the body handle blood sugar. It is injected under the skin once a week with a pen. The doctor starts at a low dose and raises it slowly.


Who Mounjaro is for

  • Adults with obesity as assessed by a doctor
  • Adults with type 2 diabetes who need better control and weight loss
  • Overweight adults with weight-related conditions
  • Residents or expats who can attend regular follow-up


Who should avoid Mounjaro

  • Personal or family history of medullary thyroid cancer or MEN2 syndrome
  • Pregnancy, planning pregnancy, or breastfeeding
  • History of pancreatitis
  • Type 1 diabetes or a history of eating disorders
  • People at a healthy weight seeking quick cosmetic weight loss


What happens at the appointment

  1. In-person consultation about weight, diabetes status and medicines
  2. Measurements and blood tests as needed
  3. Doctor decides if Mounjaro is suitable
  4. Prescription is issued and filled
  5. Training on using the pen
  6. Follow-up to adjust dose and review side effects


Aftercare and flying home

  • Eat smaller meals and avoid heavy, greasy food
  • Drink enough water and keep protein intake up
  • If you use oral contraceptives, ask the doctor about backup contraception when starting or raising the dose
  • Store pens as the label says and carry them in hand luggage when flying
  • Tell other doctors and anaesthetists you are on Mounjaro
  • Plan continued prescribing and monitoring at home


Side effects and risks

  • Nausea, diarrhoea, vomiting or constipation, mainly early on
  • Reduced appetite, tiredness or indigestion
  • Low blood sugar if combined with insulin or some diabetes tablets
  • Rarely pancreatitis or gallbladder problems: severe stomach pain needs urgent care
  • Weight regain after stopping


How much does Mounjaro cost in Seoul?

₩300,000–₩800,000 per month (about US$220–600 per month) — Cost depends mainly on the dose, plus consultation and test fees. For weight loss it is generally not covered by Korean health insurance. As a newer medicine in Korea, prices may change. All prices are estimates.


Why get Mounjaro in Korea?

Mounjaro has recently become available in Korea, and some expats and visitors find access or price better than at home. It needs ongoing dose changes and monitoring, so it suits people who can keep seeing a doctor.

Prices are estimates gathered for Seoul clinics and change with brand, dose and promotions — confirm a quote with the clinic before booking. This page is general information, not medical advice; a doctor will assess whether a treatment suits you at consultation.
