How to prevent constipation with ozempic

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.

Constipation appears in the prescribing information for GLP-1 receptor agonists. What follows is what the labelling actually lists — a reference for "is this a documented effect", not a way to work out what is causing your particular symptom.

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.

Ozempic titration schedule

This is the labelled default. Holding at a step longer than shown is common practice and is a decision for your prescriber. Transcribed from the Ozempic prescribing information (label revised 10 June 2026); checked against that label on 7 August 2026.

Gastrointestinal effects are generally reported as worst in the days following a dose increase and easing as the body adjusts — which is the entire reason the schedule is stepped rather than immediate. That pattern is also why holding at a step, rather than pushing through, is such a common adjustment. Anything severe, persistent or unexpected warrants contacting your prescriber rather than searching for reassurance.

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.
