Ozempic Dose Adjustment
Start Ozempic at 0.25 mg subcutaneously once weekly for 4 weeks, then increase to 0.5 mg weekly for 4 weeks, followed by 1.0 mg weekly for 4 weeks, and finally 1.7 mg weekly for 4 weeks until reaching the maintenance dose of 2.4 mg weekly after 16 weeks. 1, 2
Standard Titration Protocol
The dose escalation follows a fixed schedule designed to minimize gastrointestinal side effects:
- Weeks 1-4: 0.25 mg once weekly 1, 2, 3
- Weeks 5-8: 0.5 mg once weekly 1, 2, 3
- Weeks 9-12: 1.0 mg once weekly 1, 2, 3
- Weeks 13-16: 1.7 mg once weekly 1, 2
- Week 17 onward: 2.4 mg once weekly (maintenance) 1, 2
For diabetes management specifically (as opposed to weight management), the FDA-approved dosing differs: initiate at 0.25 mg weekly for 4 weeks, then increase to 0.5 mg weekly, with a maximum dose of 1.0 mg weekly if additional glycemic control is needed. 1, 3
Managing Missed Doses
If 2 consecutive doses are missed: Resume at the same dose if the patient previously tolerated it well; otherwise, consider lowering to the previous dose level. 1, 2
If 3 or more consecutive doses are missed: Restart the entire titration schedule from 0.25 mg weekly. 1, 2
If less than 5 days since missed dose: Administer as soon as possible. 2
If more than 5 days since missed dose: Skip the missed dose and resume at the next scheduled time. 2
Dose Optimization Considerations
Some patients achieve adequate response at submaximal doses (0.5 mg, 1.0 mg, or 1.7 mg weekly) and can continue long-term at these lower doses without progressing to 2.4 mg. 1, 2 This is particularly relevant when patients experience significant weight loss or glycemic improvement before reaching maximum dose.
The gradual titration is specifically designed to reduce nausea, vomiting, and other gastrointestinal adverse effects, which are the most common side effects. 1, 2 Slower titration may be warranted in patients experiencing GI challenges. 1
Special Populations
Renal impairment: No dose adjustment required regardless of kidney function, including end-stage renal disease or dialysis. 1, 2, 4, 3
Hepatic impairment: No dose adjustment required. 1, 3
Elderly patients: No dose adjustment required, though greater sensitivity in some older individuals cannot be ruled out. 3
Critical Drug Interactions Requiring Dose Adjustments
When used with insulin or insulin secretagogues (sulfonylureas): Reduce the dose of insulin or sulfonylurea to minimize hypoglycemia risk. Monitor closely for hypoglycemia and adjust accordingly. 1, 2, 4
Do not combine with: Other GLP-1 receptor agonists or DPP-4 inhibitors. 1, 2
Administration Timing
Ozempic can be administered at any time of day, with or without meals, providing flexibility for patient convenience. 2 The injection day can be changed if needed, as long as at least 2 days (48 hours) have elapsed between doses. 3
Common Pitfalls to Avoid
- Advancing doses too quickly: This significantly increases gastrointestinal side effects and treatment discontinuation. 1, 2
- Not counseling on dietary modifications: Reducing meal size, mindful eating practices, and decreasing high-fat or spicy foods can mitigate GI side effects during titration. 1
- Failing to adjust concomitant diabetes medications: Particularly insulin and sulfonylureas, which increases hypoglycemia risk. 1
- Discontinuing before scheduled surgery: Consider stopping 3-4 days before elective procedures due to delayed gastric emptying effects. 1
