Mounjaro has become one of the most talked about weight loss injections in the UK, and many patients starting treatment have similar questions about dosing. One of the most common is whether it is possible to stay on Mounjaro 2.5 mg rather than moving up to higher doses. This is a reasonable question, particularly for those who feel they are responding well or are concerned about side effects.
The Care Pharmacy supports patients throughout their weight loss journey, including guidance on dose progression. A better understanding of Mounjaro dosing and the role of the 2.5 mg dose can help you decide what works best for you. If you are considering treatment or reviewing your current dose, you can start an online consultation form to receive personalised clinical guidance.

What Is Mounjaro 2.5 Mg Used For?
Mounjaro 2.5 mg is the usual starting dose for patients beginning treatment. It is designed as an introductory dose to allow the body to adjust to the medication. At this level, the focus is often on improving tolerance rather than maximising weight loss.
The 2.5 mg dose helps introduce appetite regulation and supports early changes in eating behaviour. Some patients notice reduced hunger and improved portion control even at this stage, while others experience more subtle effects.
Can You Stay On Mounjaro 2.5 Mg Long Term?
In some cases, patients may remain on Mounjaro 2.5 mg for longer than the initial period. This usually depends on individual response, tolerance, and overall progress. While many treatment plans involve gradual dose increases, staying on a lower dose can be appropriate for certain individuals.
Reasons someone may stay on 2.5 mg include:
- Good appetite control at the starting dose
- Steady and gradual weight loss
- Sensitivity to side effects at higher doses
- Preference for slower dose progression
Clinical review is essential before deciding to remain on a lower dose. Support from our team is available if you are unsure whether a dose increase is right for you – get in touch today.

Why Do Most Mounjaro Patients Increase Their Dose?
Mounjaro dosing is typically increased over time to enhance appetite suppression and support continued weight loss. As the body adapts to treatment, the initial effects of a lower dose may reduce.
Increasing the dose can help:
- Maintain appetite control as tolerance develops
- Support continued weight loss
- Reduce the risk of weight loss plateaus
However, increasing the dose is not always necessary or immediate. Decisions are based on how you respond rather than following a fixed schedule.

What Happens If You Do Not Increase Your Mounjaro Dose?
Staying on Mounjaro 2.5 mg may still support some appetite control, but weight loss may slow over time. This does not mean treatment has failed. It may indicate that your body has adapted to the dose.
Some patients choose to remain at a lower dose for comfort or tolerability reasons. Others move up gradually once side effects settle. The key is regular review rather than making changes independently.
Signs It May Be Time To Review Your Dose
- Appetite returning to previous levels
- Weight loss plateau lasting several weeks
- Reduced feeling of fullness after meals
