Microdosing semaglutide

By David Chen·Editor·Reviewed August 2026

The word is not in the label²

We searched the full published label — 212,786 characters — for “microdose” and “microdosing”. Neither appears. That is worth stating precisely, because the term is used freely by sellers and it carries an implication of an established practice with a known dose range, which the label does not support.

What the lowest approved dose is for¹

0.25 mg is a starting dose, and the label is explicit that it is there to reduce gastrointestinal reactions rather than to produce weight reduction. The schedule then moves through 0.5, 1 and 1.7 mg to a maintenance dose — see the titration schedule. A dose that is never escalated from is not a dose the schedule describes.

What that absence does and does not mean²

It does not mean a lower dose is dangerous, and it does not mean it does nothing. It means the approved trials did not test it, so nobody can quote a rate, an effect size or a safety profile for it from this label — and any figure presented as if they could has come from somewhere else.

That matters commercially as well as clinically. A smaller dose from the same vial lasts longer, so “microdosing” is also a claim about cost. What a vial actually costs per calendar month is on the index, and it does not depend on how the dose is described.

What this page is not

This is not advice for or against any dose. It reports what the approved label contains, which in this case is a documented absence. Your dose is a decision for your prescriber.
