What is Mounjaro

Mounjaro is a prescription medication formulated for weight loss and long-term weight management.

Active ingredient

Mounjaro contains tirzepatide, which helps regulate your appetite and blood sugar levels.

Suitability

Mounjaro is suitable for adults with obesity (BMI over 30) or those overweight (BMI over 27) with certain weight-related health conditions.

Effectiveness

Clinical studies have shown significant weight loss, with patients losing around 26% of their body weight in 84 weeks.

Mounjaro dosing schedule

Mounjaro is taken once a week. Northampton Weightloss (Powered by Regent Pharmacy) experts suggest following a schedule to gradually increase the dosage to help you get the most from your treatment.

Weeks 1–4

Start with a dose of 2.5mg once a week. This initial dose is designed to help your body gradually adjust to the medication.

Weeks 5–8

Increase the dose to 5mg, taken once weekly. This increase helps to enhance the medication's efficacy while monitoring your tolerance.

Weeks 9–12

Increase the dose again to 7.5mg once weekly. This step depends on how well you've tolerated the previous doses.

Weeks 13-16

Increase the dose to 10mg once weekly. This dose is part of the standard progression aiming for optimal weight loss.

Weeks 17+

Depending on your doctor's advice and how well you've tolerated the 10mg dose, you may increase to a maximum of 15mg once weekly.

This structured dosing schedule helps to minimise side effects and allows your body to adapt to each new dose level gradually. Always follow your healthcare provider's instructions and discuss any concerns with them to ensure the best outcomes from your treatment plan. Not all patients will need to reach the highest dose. Your dose is tailored based on your response and how you tolerate the medication. It may be that you need to increase the dose more slowly than every 4 weeks, but you must not increase the dose more quickly than that.
