One of its most convenient features is its once-weekly injection schedule, which simplifies treatment adherence. Patients looking for effective diabetes or weight management solutions often ask, Is Mounjaro a once-weekly injection? The answer is yes—it is designed to be administered just once per week, making it a practical choice for long-term therapy. For those exploring options like Mounjaro Injections Dubai, understanding its dosing regimen, benefits, and potential side effects is crucial.
In this comprehensive guide, we’ll explore Mounjaro’s weekly dosing, how it works, its benefits, and common questions about its use.
How Does Mounjaro Work?
Mounjaro is a dual glucose-dependent insulinotropic polypeptide (GIP) and glucagon-like peptide-1 (GLP-1) receptor agonist. It works by:
- Enhancing insulin secretion (only when blood sugar is high)
- Reducing glucagon secretion (a hormone that increases blood sugar)
- Slowing gastric emptying (leading to prolonged satiety)
- Promoting weight loss (by reducing appetite)
Because of these mechanisms, it helps regulate blood sugar levels while also supporting weight management.
Mounjaro Dosing Schedule: Once-Weekly Injection
Mounjaro is indeed administered as a once-weekly subcutaneous injection. The dosing schedule is as follows:
Mounjaro Dosage Titration
| Week | Starting Dose | Maintenance Dose |
|---|---|---|
| 1-4 | 2.5 mg | N/A |
| 5-8 | 5 mg | Optional |
| 9+ | Adjust as needed (5 mg, 10 mg, 15 mg) | 5 mg, 10 mg, or 15 mg (based on tolerance and efficacy) |
Patients typically start with a 2.5 mg dose for the first four weeks to minimize side effects, then gradually increase to higher doses (5 mg, 10 mg, or 15 mg) based on their doctor’s recommendation.
