Numbers from the label and the pooled trials
- Vomiting was reported by 25% of adults on Wegovy 2.4 mg and 6% on placebo in the weight-reduction trials.[1]
- In the 2.4 mg trials, vomiting led 1.2% of Wegovy-treated adults to stop treatment, against 0% on placebo.[1]
- Severe stomach side effects were reported in 4.1% of adults on Wegovy injection and 0.9% on placebo.[1]
- Stomach side effects were reported most often during dose escalation.[1]
- In pooled STEP 1 to 3, a vomiting episode lasted a median of 2 days on semaglutide 2.4 mg, and the share of people vomiting peaked at about week 20.[2]
- Most reports of kidney injury after approval were in people dehydrated by nausea, vomiting or diarrhea.[1]
Stop and get help
- Severe stomach pain that will not go away, with or without vomiting: stop Wegovy and call your healthcare provider right away.[1]
- Upper stomach pain, yellow skin or eyes, fever or clay-colored stools: call your healthcare provider.[1]
- Swelling of the face, lips, tongue or throat, trouble breathing or swallowing, or fainting: stop Wegovy and get medical help right away.[1]

To settle on the call
- Should my next injection go ahead, wait, or be at a lower dose?
- Do any of my tablets need a different plan while I keep vomiting?
- Do I need a blood test for kidney function or salts?
- Is an anti-sickness medicine right for me, and what does it interact with?
