From the Ozempic and PPI labels

  • In Ozempic's placebo-controlled trials, indigestion was reported by 3.5% (0.5 mg) and 2.7% (1 mg) versus 1.9% on placebo, reflux by 1.9% and 1.5% versus 0%, and belching by 2.7% and 1.1% versus 0%.[1]
  • Ozempic is injected once a week on the same day, at any time of day, with or without meals.[1]
  • Ozempic delays gastric emptying and may affect the absorption of oral medicines taken with it.[1]
  • The omeprazole (Prilosec) label says to take it before meals.[2]
  • The pantoprazole (Protonix) label says adult CYP2C19 poor metabolizers need no dose change.[3]

Contact your healthcare provider right away

  • Severe stomach pain that will not go away, with or without vomiting (Ozempic guide: stop Ozempic and call right away).[1]
  • Nausea, vomiting or diarrhea that does not go away (Ozempic guide: tell your provider right away).[1]
  • Watery stools or stomach pain that does not go away (PPI guide: call your doctor right away).[2]

To ask

  1. Do these symptoms look like reflux, an Ozempic side effect, or both?
  2. Do I still need my PPI at this dose, and for how long?
  3. Given how long I have taken a PPI, should my magnesium or vitamin B12 be checked?
  4. Would a slower Ozempic dose increase help my symptoms?
  5. If I switch to Rybelsus or Ozempic tablets, how should I time my PPI?
