At Sudbury Court Pharmacy, we understand that every weight loss journey is unique. One of the most common questions we receive from patients using Mounjaro (tirzepatide) is whether it’s possible to remain on a lower dose long-term, and still maintain results. It’s a valid concern, especially when balancing medication costs, side effects, and long-term sustainability.

Mounjaro, originally developed for managing type 2 diabetes, has rapidly gained attention for its powerful weight loss benefits. It works by mimicking the actions of two hormones (GLP-1 and GIP) that help regulate appetite and blood sugar. This dual action has shown impressive results, but does everyone need to progress to the highest dose to achieve or maintain their goals?

Let’s explore the nuances of staying on a lower Mounjaro dose for weight loss and the factors that influence ongoing treatment.

How Mounjaro Dosing Works

Mounjaro is typically started at a low dose, often 2.5 mg weekly, as a way for the body to gradually adjust. This starter dose is not intended for long-term weight loss but rather to reduce gastrointestinal side effects like nausea. After four weeks, the dose is usually increased in 2.5 mg increments, with most weight loss studies evaluating outcomes at doses of 5 mg, 10 mg, and 15 mg.

Each dose level tends to show improved results in terms of appetite suppression and fat loss, but not every patient needs or tolerates the higher doses. While higher doses are associated with more significant weight loss on average, that doesn’t mean a lower dose is ineffective for all.

Can You Maintain Weight Loss on a Lower Dose?

Yes, it is possible to maintain weight loss on a lower Mounjaro dose—especially if you’ve already achieved your target weight or if your body responds well to the medication early on. At Sudbury Court Pharmacy, we’ve seen patients reach a stable and healthy weight using 5 mg or 7.5 mg doses, without needing to escalate further.

Maintenance, however, depends on more than just medication. Lifestyle factors, such as a balanced diet, regular physical activity, and behavioural support, play a crucial role in sustaining progress. Patients who adopt healthy habits alongside Mounjaro often find that lower doses are sufficient for long-term use.

Benefits of Staying on a Lower Dose

Remaining on a lower Mounjaro dose for weight loss offers several advantages:

Fewer side effects: Nausea, diarrhoea, and fatigue are more common at higher doses. Many patients find these effects manageable at lower doses.

Better affordability: As private prescriptions are not always covered by the NHS, staying at a lower dose can help reduce out-of-pocket costs.

Improved adherence: Patients are more likely to stick to a medication routine if they feel well and aren’t burdened by severe side effects.

However, it’s important to evaluate your response regularly with your healthcare provider. Weight regain can occur if the dose is too low to suppress appetite effectively or if lifestyle habits slip.

Factors Influencing Long-Term Treatment Plans

Several factors determine whether you can remain on a lower dose of Mounjaro over time:

Individual response: Everyone’s body is different. Some people experience excellent results with lower doses, while others may need more to overcome stronger hunger cues.

Weight loss goals: If your goal is modest weight loss (e.g., 5–10% of your starting weight), a lower dose may suffice. For more substantial loss, a higher dose might be necessary initially, followed by tapering.

Tolerance and side effects: If you experience adverse effects at higher doses, your clinician may recommend staying at the highest well-tolerated dose rather than continuing to increase.

Comorbidities: If you have conditions like diabetes, fatty liver disease, or high cholesterol, your dose may need adjusting to support broader health goals.

Tailoring Treatment to the Individual

At Sudbury Court Pharmacy, our priority is personalisation. There is no “one-size-fits-all” Mounjaro dose for weight loss. We guide patients through a carefully monitored plan, adjusting dosages based on weight changes, side effects, and lifestyle improvements.

Our clinical pharmacists collaborate with prescribing doctors to ensure you are on the optimal dose for both effectiveness and tolerability. For some, this may mean remaining on 5 mg or 7.5 mg for months or even years. For others, gradually increasing and then stepping down after achieving results may be the right path.
