How to read Japanese medicine labels
皮下注
Subcutaneous injection. Storage, packaging, device format, and temperature control can matter.
錠
Tablet. For oral GLP-1 products, strength and administration timing may be as important as tablet count.
アテオス
The ATEOS prefilled device format used for Japanese Mounjaro listings.
キット / 本 / 箱
Package units. A request should specify whether you mean one pen, one kit, one box, or a tablet count.
mg and mL
Do not treat strength, concentration, and volume as the same thing. Similar names can refer to different formats.
販売終了
Discontinued. Support needs to verify whether any current route exists before discussing next steps.
Mounjaro request checklist
For Mounjaro, Japanese patient materials identify tirzepatide as the active ingredient and describe once-weekly subcutaneous use under medical direction. Prepare the following before asking support:
- Exact product name, such as Mounjaro Subcutaneous Injection 5 mg ATEOS.
- Strength: 2.5 mg, 5 mg, 7.5 mg, 10 mg, 12.5 mg, or 15 mg.
- Quantity: number of pens/kits or boxes.
- Whether you are starting, continuing, or changing from another GLP-1 product.
- Destination country or region.
- Whether you are starting, continuing, or switching from another GLP-1 product.
- Storage expectation: injection products may require cold-chain handling.
Common GLP-1 comparison questions
Mounjaro vs Ozempic
The active ingredients are different: tirzepatide for Mounjaro and semaglutide for Ozempic. Do not treat them as interchangeable by dose number.
Ozempic vs Wegovy
Both are semaglutide injections, but product names, strengths, use context, and package formats differ. Support needs the exact Japanese listing.
Rybelsus vs injection products
Rybelsus is an oral tablet. The request should include tablet strength and count, not injection pen quantity.
Safety and suitability checks
GLP-1 medicines may not be suitable for everyone. Product materials mention special caution around type 1 diabetes, diabetic ketoacidosis, severe infection or surgery, pancreatitis history, severe gastrointestinal disorders, pregnancy or breastfeeding, low blood sugar risk, and possible interactions with other medicines.
Commonly mentioned adverse reactions include nausea, vomiting, diarrhea, abdominal discomfort, constipation, and low blood sugar risk, especially when used with other glucose-lowering medicines.
Common request mistakes
- Asking only for an English brand name.
- Confusing semaglutide tablets with semaglutide injection products.
- Asking for the strongest dose without medical review.
- Not mentioning destination country.
- Not preparing prescription or medical-history context.
- Ignoring storage conditions for injection products.
