Semaglutide Side Effects by Dose: From 0.25 mg to 2.4 mg
Nausea at 0.25 mg isn't the same as nausea at 2.4 mg. A step-by-step map of what to expect — and when to worry.
Full article coming soon. This post will map typical semaglutide side effects to each titration step, with clinical-trial frequencies and guidance on when a side effect warrants a prescriber call. Until then, see our Wegovy titration walk-through for side-effect notes at each step.
Why side effects vary by dose
Semaglutide's most common side effects — nausea, vomiting, constipation, diarrhea — are dose-dependent and time-limited. They peak shortly after each step-up and fade within 7–10 days as gastric emptying re-adapts. Understanding this pattern makes it easier to distinguish between "expected" side effects (manageable) and "red flag" side effects (need prescriber attention).
