Ondansetron
The tablet that makes dose-increase week survivable. Prescribed with your GLP-1, shipped in the same box.
Add-on · nausea cover while titrating
Ondansetron is the anti-sickness drug used after chemotherapy and surgery, and it is very good at its job. On a GLP-1 programme it exists for one reason: so that the two or three rough days after a dose increase do not become the reason you quit.
It is prescribed as needed rather than daily. Most members use four to eight tablets a month, all clustered around the increase.
It blocks 5-HT3 serotonin receptors in the gut and in the vomiting centre of the brainstem. It stops the signal rather than treating the cause, which is exactly what you want here — the cause is a medication you are deliberately taking.
What most people get, and the bit that matters
This list is not exhaustive and does not replace the consultation. The intake form asks the questions that decide it, which is why the honest answers matter more than the fast ones.
No. If you are on a Renu weight plan, adding ondansetron is a message to your doctor and a line on your next delivery note.
Then the titration is moving too fast for you. Message your doctor — the answer is almost always to hold your current dose for another two weeks rather than to medicate through it.
