GLP-1 side effects reddit

You are dealing with a symptom and want to know if it is expected.

Reference and calculator, not medical advice. Dosing figures below are transcribed from FDA-approved prescribing information and link back to it. Last reviewed August 2026.

Forum threads are a self-selected sample. People post when something is wrong far more often than when nothing is, so a thread is a reliable guide to what is possible and an unreliable guide to what is common. Reading twenty accounts of these effects tells you the effect is real; it does not tell you the rate, and no amount of scrolling converts it into one.

Listed in the prescribing information

Common adverse reactions listed for GLP-1 receptor agonists as a class.

These products carry a boxed warning regarding thyroid C-cell tumours observed in rodent studies, and are contraindicated in people with a personal or family history of medullary thyroid carcinoma or MEN 2. Read the full prescribing information for your specific product and discuss it with your prescriber — this summary is not complete and is not a substitute for that document.

The list above is the other half of the picture — what manufacturers were required to document, without the selection effect. It is worth reading both for different things. A thread can describe what an effect actually feels like day to day, which no label attempts. A label can tell you how often it happened in a trial, which no thread can.

Sources and last review

Every dosing figure on this page is transcribed from an FDA-approved label and links back to it. Conversions are arithmetic you can repeat by hand. Nothing here is reviewed by a clinician, and this site does not employ one — which is exactly why what I do publish stays traceable to its source.

Transcribed from the labels above and checked by me — Gavin, who builds this site, takes a GLP-1, and is not a clinician. Last reviewed August 2026. Found an error? [email protected] — I treat corrections as bugs. How this site is built and funded.
