Semaglutide Side Effects — What to Expect

The most common side effects of semaglutide are gastrointestinal — nausea (25-31%), diarrhea (19-23%), vomiting (8-12%), constipation (6-10%), and decreased appetite (9-11%). Most are transient and dose-related, decreasing as the body adjusts.

The full picture

Side effect management strategies include: starting at 0.25 mg and following the standard titration schedule; eating smaller meals; staying hydrated; avoiding high-fat or high-sugar meals during titration; and discussing antiemetic medications with the prescriber if nausea is severe. Serious adverse events are rare but include pancreatitis, gallbladder disease, kidney injury (typically dehydration-related), and severe allergic reactions. Semaglutide carries a boxed warning regarding the risk of thyroid C-cell tumors based on rodent studies.
