What the Ozempic label reports

  • Most reports of nausea, vomiting or diarrhea came during dose escalation.[1]
  • In placebo-controlled trials, diarrhea was reported by 8.5% on 0.5 mg and 8.8% on 1 mg, against 1.9% on placebo.[1]
  • 3.1% on 0.5 mg and 3.8% on 1 mg stopped treatment because of stomach side effects, against 0.4% on placebo.[1]
  • Severe stomach side effects were reported in 0.4% on 0.5 mg and 0.8% on 1 mg, and in none on placebo.[1]
  • Diarrhea, nausea and vomiting can cause dehydration, which can harm the kidneys.[1]

Call your provider right away

  • Diarrhea, nausea or vomiting that does not go away.[1]
  • Stomach problems that are severe or will not go away.[1]

For the call

  1. Should I stay on this dose longer before the next increase?
  2. Could metformin or another medicine be adding to this?
  3. Which antidiarrheal can I use with my other medicines, and for how long?
  4. When should my kidney function be checked if this continues?
