Starting Dosage for Ozempic
Ozempic (semaglutide) begins at 0.25 mg injected subcutaneously once weekly for 4 weeks. This initial dose minimizes gastrointestinal side effects like nausea.[1]
How to Increase the Dose
After 4 weeks, increase to 0.5 mg once weekly. If blood sugar control needs improvement and the patient tolerates it, raise to 1 mg once weekly after at least 4 more weeks. The maximum dose is 2 mg once weekly, approved for better glycemic control in type 2 diabetes.[1][2]
Dosage for Weight Management
For chronic weight management in adults with obesity or overweight plus comorbidities (under the Wegovy brand name, same active ingredient), dosing mirrors Ozempic but escalates higher: start at 0.25 mg weekly for 4 weeks, then 0.5 mg, 1 mg, 1.7 mg, up to 2.4 mg weekly. Ozempic's 2 mg max applies primarily to diabetes.[1][3]
Administration Tips
Inject into the abdomen, thigh, or upper arm, rotating sites. Use on the same day each week, with or without food. If a dose is missed, take it within 5 days; otherwise, skip and resume the schedule. No dose adjustment for mild kidney/liver issues, but monitor closely.[1]
Adjustments for Special Cases
- Elderly or kidney-impaired: Start low and titrate slowly due to higher GI risk.
- Children (12+ with type 2 diabetes): 0.25 mg weekly for 4 weeks, then 0.5 mg or up to 1-2 mg based on weight and response (≥60 kg for 2 mg).
- Pregnancy/breastfeeding: Discontinue at least 2 months before planned pregnancy.[1][2]
Why Titrate Slowly?
Rapid increases raise nausea, vomiting, or diarrhea risk, which affects 20-44% of patients initially. Slow titration improves adherence and outcomes in trials like SUSTAIN.[1][4]
