GLP-1 Receptor Agonist Doses for Weight Loss

GLP-1 receptor agonists approved for weight loss use semaglutide at a maintenance dose of 2.4 mg once weekly and liraglutide at 3.0 mg daily after gradual escalation. For related context, see our guide to Top Meal Replacement Shakes for Weight Loss.

These medications require slow dose increases over weeks or months to reduce gastrointestinal side effects while reaching effective levels for appetite reduction and weight management. Dosing always occurs alongside diet and exercise changes.

Semaglutide Weekly Injection Schedule

Semaglutide for weight management starts at 0.25 mg injected once weekly for the first four weeks. The dose then rises to 0.5 mg weekly for the next four weeks, followed by 1.0 mg, then 1.7 mg, and finally 2.4 mg at week 17 as the target maintenance level. Increases occur only if the prior dose is tolerated.

Some patients remain at 1.7 mg if 2.4 mg produces excessive side effects. This schedule comes from clinical use data for the formulation indicated specifically for chronic weight management.

Liraglutide Daily Dosing Progression

Liraglutide begins at 0.6 mg injected daily for at least one week. The dose escalates to 1.2 mg daily, then to 1.8 mg if more control is needed, and finally reaches the 3.0 mg maintenance dose by week five for weight management indications.

Each step requires a minimum of one week at the lower dose before moving up. Daily administration differs from the weekly options and demands consistent timing.

Tirzepatide Escalation for Weight Loss

Tirzepatide starts at 2.5 mg weekly for four weeks. Subsequent steps add 2.5 mg every four weeks as tolerated, moving through 5 mg, 7.5 mg, 10 mg, 12.5 mg, and up to a maximum of 15 mg weekly. Intermediate doses may receive limited insurance coverage periods.

This dual GLP-1 and GIP agonist follows a similar slow titration pattern to the single agonists but reaches higher absolute milligram amounts.

General Titration and Missed Dose Rules

All GLP-1 agents for weight loss follow four-week escalation intervals when possible. Patients who miss doses for more than two weeks often restart at a lower dose to limit stomach upset. Oral semaglutide versions use different daily starting amounts of 1.5 mg or 3 mg with monthly increases. You can also explore Weight Loss Surgery Costs in Mexico for a closer comparison.

Compounded versions lack standardized dosing data and carry risks of inaccurate measurement or contamination, so they are not recommended when approved products are available.

Maintenance Dose Selection

Approved maintenance options include semaglutide at 1.7 mg or 2.4 mg weekly, liraglutide at 3.0 mg daily, and tirzepatide at 5 mg, 10 mg, or 15 mg weekly. The lowest effective dose that maintains weight loss with acceptable tolerability is preferred.

Individual response varies, and some patients achieve results at intermediate levels without advancing to the highest approved amount. Regular medical review determines whether to hold or adjust the dose.
