For patients on lower doses of tirzepatide (e.g., 5 mg), switching to a less frequent dosing schedule (e.g., every two weeks) while simultaneously increasing the dose size (e.g., to 10 mg or 15 mg) can maintain or even exceed the weight loss efficacy of the standard once-weekly regimen.

If you are on a lower dose of tirzepatide (5 mg) and find it expensive, ask your doctor if switching to a higher dose (10 mg or 15 mg) taken every two weeks is an option. This strategy might keep your weight loss results the same or even better while cutting your costs in half. However, be aware that higher doses may increase side effects, so this requires careful medical supervision.

If the decrease in dose frequency involves an appropriate increase in dose size, then approximately 100% of the weight loss is maintained.
