Understanding GLP-1 medication dosing can be overwhelming, especially with all the numbers and scientific jargon involved. If you’re feeling lost in the complexities of GLP-1 dosing or simply want to feel more confident about it, you’ve come to the right place. In this article, we’ll break down everything you need to know with expert insights.

Why GLP-1 Dosing Starts Low
GLP-1 dosing typically begins at a low level to avoid tolerance issues and common side effects related to digestion, appetite signaling, and gut motility, as explained by New York endocrinologist Rocio Salas-Whalen, MD. Starting low allows the brain and gastrointestinal system to adjust, minimizing side effects like nausea, reflux, or fatigue. This initial phase, known as titration, involves carefully adjusting the dose. Once tolerated, the dose can be gradually increased or maintained under the guidance of your healthcare provider.
Another reason for starting with a low dose, as lipid and obesity specialist Dr. Spencer Nadolsky points out, is that some individuals may respond well to a lower dose and not require a higher one. In such cases, it’s important not to accelerate weight loss too quickly at the expense of well-being.
How Providers Make Dosing Decisions
Healthcare providers consider both weight loss progress and side effects when determining dosing adjustments. Clinicians typically aim for patients to lose around 0.5% to 1% of their total body weight per week. If weight loss is slower than expected, the dose may be increased. However, if side effects are present, providers may opt to maintain the current dose. The goal is to find a maintenance dose that allows for weight and metabolic health stability without unwanted side effects.
Starting Doses for Different GLP-1 Medications
Tirzepatide
Tirzepatide, found in injectable medications like Mounjaro and Zepbound, typically starts at 2.5 mg weekly and can be increased gradually.
Semaglutide Injection
Injectable semaglutide, known as Wegovy, starts at 0.25 mg weekly and is gradually increased over time.
Oral Semaglutide
Oral semaglutide doses vary from 1.5 mg daily to higher levels, depending on the specific medication and treatment plan.
