How does Mounjaro Injection Work?
Mounjaro (Tirzepatide) is a weight loss medication that works by mimicking the actions of two important gut hormones; Glucose-dependent insulinotropic polypeptide (GIP), and Glucagon-like peptide-1 (GLP-1). It promotes weight loss through mechanisms including;
- Controlling blood sugar — Regulates insulin secretion in response to glucose levels
- Regulating appetite — Slows gastric emptying making patients feel full for longer
- Glucagon suppression — Reduces the amount of glucose released by the liver
Unlike traditional weight loss methods, Mounjaro actively alters the brain’s hunger signals helping individuals lose weight sustainably.
How Long Does Mounjaro Take to Work?
First Few Weeks
Mounjaro starts working within hours of injection, influencing blood sugar levels between 8 to 72 hours, with the average being around 24 hours. Most individuals begin to experience appetite suppression and changes in glucose levels approximately four weeks after starting the Mounjaro weight loss injection.
Month 1-3: Noticeable Weight Loss
- By the end of one month, many people report a gradual weight loss.
- Most individuals achieve a 5-10% decrease in total body weight.
- Combining a balanced diet with regular exercise can accelerate weight loss results.
Month 3-6: Consistent Progress
- By this stage, the majority of individuals experience substantial weight loss.
- Depending on the progress, some may need dosage adjustments.
- Studies indicate that with consistent use, around 15-20% of body weight is shed during this time.
How Fast Can You Lose Weight on Mounjaro?
Losing weight depends on person to person. In clinical trials, Mounjaro (Tirzepatide) has demonstrated significant weight loss results when individuals took the highest dose of 15mg for a duration of 10 to 12 months, around 90% lost at least 5% of their starting body weight.
Additionally, another study showed participants who received a 15mg weekly dosage for 72 weeks experienced an average weight reduction of 22.5% of their starting body weight. These findings highlight Mounjaro’s potential as an effective treatment for long-term weight management.
Mounjaro Maintenance Dosages for Long-term Results
For long-term results with Mounjaro (Tirzepatide), healthcare providers recommend a stable dose to manage blood sugar levels and prevent weight regain. For the first 4 weeks, the starting dose of Mounjaro is 2.5 mg. Once you have achieved a desired outcome, transitioning to a maintenance dose can help sustain progress.
The common maintenance doses for Mounjaro are;
- 5 mg
- 10 mg
- 15 mg
In a 2022 study, it was found that people using Mounjaro for a 72-week trial with 5 mg, 10 mg, or 15 mg dosage once weekly showed significant weight loss results. The exact maintenance dose varies depending on an individual’s response to the medication. Staying on a maintenance dose helps control appetite sustaining weight loss and metabolic effects.

FAQs
Mounjaro starts working after the first dose, but you may not see a difference immediately. The dose is gradually increased each month so the body can adjust to the medication.
Studies indicate that Mounjaro is fully active in the system by 4 weeks which leads to an average weight loss of around 4%.
