| Condition | Starting Dose | Maintenance Dose |
|---|---|---|
| Type 2 diabetes (Ozempic) | 0.25 mg SC once weekly for 4 weeks | Increase to 0.5 mg weekly; titrate to 1 mg or 2 mg weekly as needed for glycemic goals |

Drug Interactions
Semaglutide is not metabolized by CYP enzymes, so most interactions arise from delayed gastric emptying or additive glucose-lowering effects.
- Insulin and sulfonylureas (e.g., glipizide, glimepiride): Substantially increased risk of hypoglycemia. Reduce the insulin or sulfonylurea dose — often by 20 percent or more — when initiating semaglutide, and monitor glucose closely.
- Oral medications (Rybelsus interactions): Oral semaglutide must be taken first thing in the morning with no more than 4 ounces of water, on an empty stomach, and at least 30 minutes before any other oral medication, food, or beverage. Otherwise, absorption is markedly impaired.
- Warfarin and other narrow-therapeutic-index oral drugs: Slowed gastric emptying may shift absorption profiles. Monitor INR closely after initiating or escalating semaglutide.
- Levothyroxine: Reports of altered absorption with GLP-1 therapy. Maintain consistent timing relative to semaglutide and recheck TSH 6–8 weeks after starting.
- Other GLP-1 receptor agonists or DPP-4 inhibitors (e.g., liraglutide, dulaglutide, sitagliptin): Concurrent use is not recommended due to overlapping mechanism, no incremental benefit, and additive GI side effects.
- Alcohol: May worsen GLP-1 GI side effects and can independently raise hypoglycemia risk in patients also on insulin or sulfonylureas. Counsel moderation.
