Complete guide to Ozempic (semaglutide) dosing for diabetes and weight loss including escalation schedule, maintenance doses, and optimal titration timeline for blood sugar control and weight management.
Ozempic starts at 0.25 mg weekly for 4 weeks, then increases to 0.5 mg for at least 4 weeks. For additional blood sugar control or weight loss, it can be increased to 1 mg, and if needed, to the maximum 2 mg weekly dose. The 0.5 mg and 1 mg doses are most common for diabetes management, while higher doses are often used for weight loss.
Ozempic is FDA-approved for type 2 diabetes with a max dose of 2 mg. For weight loss specifically, Wegovy (same medication) is approved up to 2.4 mg, though some providers prescribe Ozempic 2 mg off-label for weight management.
| Week | Dose | Injection Volume | Purpose | A1C Reduction / Weight Loss |
|---|---|---|---|---|
| 1-4 | 0.25 mg | 0.19 mL | Starting dose - not therapeutic | Minimal effect / 2-4 lbs |
| 5+ | 0.5 mg | 0.37 mL | First maintenance - diabetes control | -1.0 to -1.4% A1C / 8-10% weight loss |
| 9+ | 1 mg | 0.37 mL | Enhanced diabetes/weight control | -1.5 to -1.8% A1C / 10-14% weight loss |
| 13+ | 2 mg | 0.37 mL | Maximum dose - optimal control | -2.0 to -2.2% A1C / 14-17% weight loss |

Maximum Dose
Ozempic and Wegovy contain the same medication (semaglutide) but have different maximum doses and indications. Ozempic is FDA-approved for diabetes up to 2 mg weekly, while Wegovy is approved for weight loss up to 2.4 mg weekly. The escalation schedules are similar, but Wegovy includes the additional 2.4 mg dose for maximum weight loss. Many providers prescribe Ozempic off-label for weight loss when Wegovy is unavailable or not covered.
Yes, but it's off-label use. Ozempic is only FDA-approved for type 2 diabetes, but many providers prescribe it for weight loss when Wegovy (the weight-loss formulation) is unavailable or insurance doesn't cover it. The medication and effectiveness are identical - the only difference is the FDA indication and maximum dose (2 mg for Ozempic vs 2.4 mg for Wegovy). Discuss with your provider which is appropriate for your situation.
Exactly 4 weeks. The 0.25 mg dose is a starter dose only - it's not therapeutic for diabetes or weight loss. After 4 weeks, everyone should increase to 0.5 mg. The starting dose allows your body to adapt to semaglutide and minimizes side effects when you move to the therapeutic 0.5 mg dose. Don't stay at 0.25 mg longer than 4 weeks as it won't provide meaningful blood sugar control or weight loss.
0.5 mg produces moderate weight loss (8-10% average) which is meaningful for many people. However, higher doses deliver better results: 1 mg produces 10-14% weight loss and 2 mg produces 14-17% weight loss. If your primary goal is weight loss rather than diabetes management, your provider may recommend escalating to 1 mg or 2 mg for better results. Many people start seeing good results at 0.5 mg but achieve maximum weight loss at higher doses.
Absolutely. Many people maintain long-term at 1 mg if it's controlling their diabetes well and/or delivering satisfactory weight loss. The 1 mg dose reduces A1C by 1.5-1.8% and produces 10-14% weight loss - excellent results for most patients. Only escalate to 2 mg if you need additional blood sugar control or more weight loss. There's no requirement to reach the maximum dose if a lower dose is working well for you.
Completely different medications and doses. Ozempic (semaglutide) ranges from 0.25-2 mg, while Mounjaro/Zepbound (tirzepatide) ranges from 2.5-15 mg - but you can't compare them directly. They're different drugs with different mechanisms: semaglutide is a GLP-1 agonist, while tirzepatide is a dual GIP/GLP-1 agonist. Tirzepatide typically produces slightly better results (20-25% weight loss vs 15-17%) but has a different side effect profile. Both use weekly injections with gradual dose escalation.
Many insurance plans limit coverage to specific doses, typically 0.5 mg or 1 mg. If you need a higher dose (like 2 mg) but insurance only covers lower doses, talk to your provider about: (1) Using prior authorization to get the higher dose covered, (2) Switching to Wegovy if covered for weight loss, (3) Staying at the covered dose if it's providing adequate results, or (4) Exploring compounded semaglutide options which often offer more flexible dosing.
Blood sugar improvements typically appear within 1-2 weeks, with maximum A1C reduction occurring after 12-16 weeks at a stable dose. Weight loss usually starts within the first week, with 0.5-1 pound per week at lower doses and 1.5-2.5 pounds per week at higher doses (1-2 mg). The 0.25 mg starter dose produces minimal results - significant effects begin at 0.5 mg and above. Most people see their best results after reaching and maintaining their target dose for several months.
