Mounjaro Dose Strengths: From the Lowest to the Highest
Mounjaro is a once-weekly injectable medicine supplied as pre-filled pens. According to the electronic Medicines Compendium (eMC), the commonly referenced dose strengths are 2.5 mg, 5 mg, 7.5 mg, 10 mg, 12.5 mg, and 15 mg. The starting dose is typically 2.5 mg — the lowest available strength — which is generally used during the initial weeks to help the body adjust to the medicine.
After the introductory period, the dose may be increased in a stepwise pattern. The maximum dose of Mounjaro is 15 mg, reached only after a series of gradual increases. Not everyone will reach that level — the highest dose that is appropriate for any individual is a decision for their prescriber, not something to self-direct. Titration timelines vary; some people remain at a given strength for longer if their prescriber considers that the right approach.
Why the dose is increased gradually
The stepwise approach is designed to reduce the likelihood of gastrointestinal side effects such as nausea and digestive discomfort, which are commonly reported at the start of treatment or after a dose increase. Slower titration gives the body time to adapt. For more detail on what to expect at different stages, the dose stage that works best for weight loss is worth reading alongside this page.
What about Wegovy (semaglutide)?
Wegovy (semaglutide) follows a similar principle of gradual, prescriber-led titration. Its dose strengths are different — commonly 0.25 mg, 0.5 mg, 1 mg, 1.7 mg, and 2.4 mg — with 2.4 mg being the highest maintenance dose. As with Mounjaro, the right dose and pace of increase are decisions for the prescriber. If you are on Wegovy and have questions about your dose, your prescriber or doctor is the right person to speak to.
If you want to understand more about the highest available strength in detail, see our page on the highest dosage of Mounjaro. For guidance on what to do if a weekly injection is missed, the page on managing a missed Mounjaro dose covers that topic carefully.

Tracking Your Dose Stages with GLP Trackr
Keeping an accurate record of where you are in your treatment is one of the most practical things you can do on a weekly injection schedule — and that is exactly what GLP Trackr is built for.
The app's dose logging feature lets you record each injection with the date, time, and dose strength so you always have a clear, timestamped history of your treatment. As your strength increases over time, your log reflects that progression — making it straightforward to look back and see which stage you were at during any given week.
Paired with dose reminders, the app means a weekly injection is less likely to slip by unnoticed. And because the app also lets you log any side effects you notice at each stage, you build a picture you can bring to your next prescriber appointment — far more useful than trying to recall how you felt three weeks ago.
For a broader view of your Mounjaro treatment, including what to expect at different stages, the Mounjaro treatment guide covers the wider journey.
Important: any decision about your dose — including when or whether to increase, stay, or adjust — belongs entirely with your prescriber. GLP Trackr records your journey; it does not advise on it. If you have questions about your current dose or titration schedule, always follow the guidance of your prescriber or doctor.
