From the Guidelines

Ozempic (Semaglutide) has several adverse effects, including gastrointestinal side effects, pancreatitis, and potential thyroid C-cell tumors.

Adverse Effects of Ozempic (Semaglutide)

  • Gastrointestinal side effects such as nausea, vomiting, diarrhea, and esophageal reflux are common with Ozempic use 1.
  • Pancreatitis has been reported in clinical trials, but causality has not been established, and it is recommended to discontinue Ozempic if pancreatitis is suspected 1.
  • There is a potential risk of thyroid C-cell tumors, although the human relevance is not determined, and a black box warning is in place 1.
  • Other adverse effects include injection site reactions, elevated heart rate, hypoglycemia, and gallbladder disease 1.
  • Ozempic may also cause delayed gastric emptying, which can lead to nausea and vomiting, and gradual dose titration may help mitigate these adverse effects 1.
  • Additionally, Ozempic has been associated with diabetic retinopathy complications, which may be related to its rapid and marked glucose and A1C reductions 1.
  • It is essential to use Ozempic with caution in patients with severe renal impairment or end-stage renal disease, as well as those with a history of pancreatitis or gallbladder disease 1.
