Many people have questions about dosing when starting a new GLP-1 medication like Mounjaro® (tirzepatide). Each GLP-1 agonist is a little different, which affects how much you will take and how quickly you will ramp up to the maintenance dose.
What are GLP-1 agonists?
GLP-1 agonists mimic a hormone the body naturally produces: glucagon-like peptide (GLP-1). The GLP-1 hormone helps regulate blood sugar and insulin levels, which slows digestion, curbs hunger, and leads to better glucose control. By mimicking this hormone, GLP-1 agonists have helped people lose weight, eat less, and maintain steadier blood sugar levels.
What is Mounjaro®?
Mounjaro® (tirzepatide) is a once-weekly injectable medication approved by the FDA to help manage blood sugar in adults with type 2 diabetes. It mimics two hormones—GLP-1 and GIP—which helps regulate insulin and digestion. Some healthcare providers may prescribe it off-label to support weight-related health goals when appropriate.
Mounjaro® dosing schedule
Each person’s dosage amount and schedule is different and will be determined by their medical provider. The schedule below is just a general outline of what your dosage schedule could look like:
- Weeks 1–4: 2.5 mg, injected weekly
- Weeks 5–8: 5 mg, injected weekly
- Weeks 9–12: 7.5 mg, injected weekly
- Weeks 13 and onward (maintenance): 10 mg, injected weekly
Medication is prescribed only after consultation with a licensed provider to determine appropriateness.
