What is Mounjaro?
Mounjaro is a once-weekly subcutaneous injection containing tirzepatide. It acts on both GIP and GLP-1 receptors. In Japan, it is approved for type 2 diabetes; its use for weight loss differs from its approved indication. For diabetes care, please also see our Diabetes Information.

Mounjaro is not suitable for everyone, and treatment does not guarantee results or a particular amount of weight loss. Depending on the assessment, we may suggest another approach.

Steps before a Mounjaro prescription
- Reception: You can visit without an appointment. Please come during clinic hours.
- Medical interview and examination: We review your health, medical history, medications and treatment goals.
- Explanation and consent: We explain self-pay treatment, off-label use, costs and possible side effects.
- Prescription: The doctor prescribes only if it is appropriate. A prescription may be possible on the day of your first visit, but it is not guaranteed.
- Follow-up: We review your health, side effects and use of the medicine. The doctor advises each patient on how often to return.
How to use Mounjaro
It is usually injected under the skin once a week. At our clinic, the doctor explains how to use the 2.5 mg dose listed on this page. Follow the doctor’s instructions and do not change the frequency or interval between doses on your own.
Main side effects and precautions
Gastrointestinal symptoms such as nausea, vomiting, diarrhea, constipation, abdominal pain and reduced appetite may occur. Persistent vomiting or diarrhea may lead to dehydration or kidney problems. Combining it with diabetes medicines, particularly insulin or sulfonylureas, may increase the risk of low blood sugar.
Seek medical advice promptly
Persistent, severe abdominal pain with vomiting may indicate acute pancreatitis. Stop using the medicine and seek medical advice promptly if you have symptoms such as severe abdominal pain, persistent vomiting, inability to drink fluids, reduced urine output or clouded consciousness.
Who cannot use Mounjaro or needs careful assessment?
Mounjaro must not be used by people with a history of hypersensitivity to tirzepatide or its additives, among others. Please also tell the doctor if any of the following apply to you.
- You are pregnant, may be pregnant or wish to become pregnant
- You are breastfeeding
- You have a history of pancreatitis
- You have severe gastrointestinal problems or delayed stomach emptying, such as gastroparesis
- You have a history of gallstones, cholecystitis or other biliary tract disease
- You have a history of bowel obstruction or severe constipation
- You have diabetic retinopathy or kidney problems
- You use insulin, sulfonylureas or other diabetes medicines
- You have been prescribed a GLP-1 receptor agonist, Zepbound or tirzepatide at another clinic
The difference between Mounjaro and Zepbound
Both contain tirzepatide, but their approved indications in Japan differ. Mounjaro is approved for type 2 diabetes, while Zepbound is approved for obesity that meets certain criteria. They are not used together because they contain the same active ingredient.
Self-pay treatment and use outside the approved indication
Required information for self-pay treatment
- Treatment: Tirzepatide (Mounjaro 2.5 mg) is injected under the skin once a week.
- Fees: Four 2.5 mg pens cost ¥15,000 (tax included), plus a ¥1,000 consultation fee (tax included). This treatment is entirely self-pay.
- Main side effects and risks: Nausea, vomiting, diarrhea, constipation, abdominal pain, reduced appetite, low blood sugar, dehydration, kidney problems, acute pancreatitis, biliary tract disease, bowel obstruction and anaphylaxis, among others.
- Use outside the approved indication: Mounjaro is approved in Japan for type 2 diabetes. Its use for weight loss at our clinic differs from its approved indication.
- Sourcing: Our clinic purchases Mounjaro Subcutaneous Injection 2.5 mg ATEOS (マンジャロ皮下注2.5mgアテオス) from Toho Yakuhin (東邦薬品).
- Adverse drug reaction relief scheme: Health damage resulting from use outside the approved indication may, in principle, fall outside the coverage of the scheme.
For the latest safety information, see PMDA’s Mounjaro product information.
Overseas approval and safety information: In the United States, Zepbound, which contains the same active ingredient, is approved for weight management in adults meeting certain criteria. The FDA reports thyroid C-cell tumors in animal studies; effects in humans are unknown. Overseas approval does not mean that Mounjaro is approved for weight loss in Japan. US FDA information
