Most people get some GI upset, especially while titrating up. Here's the full list — common and serious — and how to tell the difference.
Most side effects are GI — nausea, diarrhea, vomiting, constipation, stomach pain. Worst right after a dose increase, easing at a stable dose.
Per Ozempic and Wegovy prescribing information, Novo Nordisk. Not medical advice — call your prescriber about any symptom that worries you.
The most reported side effect. Slowed stomach emptying is the mechanism, not a sign anything's wrong.
Either direction is common. Fiber, water, and slower eating help most people.
Less common than nausea but listed. Persistent vomiting is a reason to call your prescriber.
Reported especially in the first weeks and after each step up in dose.
Redness or soreness where you inject. Rotating sites reduces this.
Mainly a risk if you also take insulin or a sulfonylurea for diabetes.
This list is not exhaustive. Semaglutide carries a boxed warning about thyroid C-cell tumors seen in rodent studies — it's not known if this occurs in people. Read the full prescribing information and ask your prescriber about anything unclear.
