Understanding Mounjaro Dosing Basics
Mounjaro for weight loss is a once-weekly injection, designed to help regulate appetite and support sustained weight loss. The dosage of Mounjaro typically starts low and increases over time, a process known as dose escalation, to ensure the body adapts gradually to the medication.
Mounjaro doses typically start at 2.5 mg and can be increased depending on individual tolerance. The medication progresses as follows:
- 2.5 mg – Starting dose for the first 4 weeks, allowing the body to adjust.
- 5 mg – Dose increase after 4 weeks, if well tolerated.
- 7.5 mg – After another 4 weeks, the dose increases again.
- 10 mg – The maximum recommended dose after 12 weeks, typically for most patients.
12.5 mg and 15 mg – In some cases, clinicians may adjust the dose further based on how well the patient is tolerating the medication and the progress in weight loss. These higher doses may be considered in specific scenarios, though they are not standard for every patient.
Note: The dosing schedule is personalised based on how well you tolerate the medication. Not all patients will reach the highest dose, and it is important to follow the clinician’s guidance for safe treatment progression. For more details on Mounjaro dosing, visit our Mounjaro Treatment Page.

Why Does Mounjaro Follow a Dosing Schedule?
Mounjaro for weight loss uses a gradual dose escalation strategy to improve tolerability and effectiveness. By starting with a low dose and increasing it over time, the body is allowed to adjust to the medication, minimising common side effects such as nausea and digestive discomfort.
