Ondansetron — widely known by the brand name Zofran — is a prescription anti-nausea tablet. It works by blocking serotonin (5-HT3) receptors involved in triggering the nausea reflex, calming the signals that make you feel queasy.
In a weight management context, it is most often prescribed to help patients manage treatment-related nausea, including the stomach upset some people experience when starting or adjusting GLP-1 medications. The goal is comfort and consistency — making it easier to stay on your primary treatment plan.
It is prescribed and used under medical supervision as part of your overall care. OpenDoseRx treatments are dispensed only after a licensed provider reviews your health intake and determines a prescription is appropriate for you.
