About this treatment
An anti-nausea medicine sometimes prescribed off-label for nausea during GLP-1 treatment. FDA approval applies to specific products and indications; your prescribed use may be off-label.
The science
Ondansetron blocks serotonin 5-HT3 receptors involved in nausea and vomiting. It may relieve symptoms but does not address every cause of nausea or replace assessment of severe symptoms.
Your clinician considers your symptoms, medical history, and other medicines before prescribing. Follow-up helps assess your response and whether treatment remains appropriate.
Benefits & evidence
May reduce nausea and vomiting.
May offer short-term symptom support.
Persistent nausea still needs clinical review.
Individual results vary and are not guaranteed.

A licensed clinician reviews your intake, orders any required labs and decides if treatment is right for you.

Safety information
Common side effects include headache, constipation, dizziness, and fatigue.
Discuss long QT syndrome, low potassium or magnesium, serotonergic medicines, and severe constipation; do not combine with apomorphine. Seek care for fainting, severe abdominal pain, or inability to keep fluids down.
This is an FDA-approved medication. Some uses may be off-label; your clinician decides whether it is appropriate for you.
