GLPMGRMounjaro injection sites and dose steps: what the manufacturer says
This page lists where the manufacturer says Mounjaro (tirzepatide) can be injected in the UK, the EU and the US, and its dose steps and missed-dose wording, in their own words, with the documents each comes from. It is not medical advice.
Talk to a healthcare professional. The injection areas shown come from the manufacturer's product information, and the shading shows where you've injected before. GLPMGR is not a medical device and this is not medical advice: it can't tell you where it is safe for you to inject. Talk to your doctor, pharmacist or nurse about where and how to inject, follow the instructions from your prescriber and the leaflet supplied with your medicine, and ask a healthcare professional if you are unsure, or if you have pain, lumps, bruising or any other problem at an injection site.

Mounjaro dose steps and missed doses
Most GLP-1 medicines start low and step up, which doctors call titration. This is what the Mounjaro product information says, quoted word for word. UK wording comes from the patient leaflet; US wording from the prescribing information and Medication Guide. Your prescriber’s instructions come first, and GLPMGR never works out or recommends a dose.
United Kingdom
Dose steps, in the product information’s words:
- “The starting dose is 2.5 mg once a week for four weeks. After four weeks your doctor will increase your dose to 5 mg once a week.”
- “Your doctor may increase your dose by 2.5 mg increments to 7.5 mg, 10 mg, 12.5 mg or 15 mg once a week if you need it.”
- “In each case your doctor will tell you to stay on a particular dose for at least 4 weeks before going to a higher dose.”
- “Do not change your dose unless your doctor has told you to.”
If a dose is missed:
- “If you forget to inject a dose and, it has been 4 days or less since you should have used Mounjaro, use it as soon as you remember. Then inject your next dose as usual on your scheduled day.”
- “If it has been more than 4 days since you should have used Mounjaro, skip the missed dose. Then inject your next dose as usual on your scheduled day.”
- “Do not use a double dose to make up for a forgotten dose. The minimum time between two doses must be at least 3 days.”

In GLPMGR, enter the dose steps your prescriber gave you and it fills in the right dose each time you log. The same wording is in the app, under Dose Steps & Missed Doses.
Track your Mounjaro doses and injection sites in GLPMGR
GLPMGR is a private GLP-1 tracker for iPhone, iPad and Apple Watch. Choose Mounjaro when you record a dose and it offers only the areas above for your region, shows a body map of where you have injected before, and shows the manufacturer’s rotation wording. It also follows your dose steps, reminds you when a dose is due, and keeps a note of side effects. It does not tell you where to inject, and it is independent of Eli Lilly.
