Ozempic (Semaglutide) 2 mg Dose Titration
For Ozempic subcutaneous semaglutide, initiate at 0.25 mg once weekly for 4 weeks, then increase to 0.5 mg weekly for 4 weeks, followed by 1 mg weekly for 4 weeks, and finally escalate to the 2 mg maintenance dose once weekly. 1
Standard Titration Schedule
The gradual dose escalation protocol for Ozempic follows this specific timeline:
- Weeks 1-4: 0.25 mg subcutaneously once weekly 2, 1
- Weeks 5-8: 0.5 mg subcutaneously once weekly 2, 1
- Weeks 9-12: 1.0 mg subcutaneously once weekly 2, 1
- Week 13 onward: 2.0 mg subcutaneously once weekly (maintenance dose) 1
Rationale for Gradual Titration
The 4-week intervals between dose increases are essential to minimize gastrointestinal adverse effects (nausea, vomiting, diarrhea, constipation), which are the most common side effects of GLP-1 receptor agonists. 2, 1 These adverse events are typically transient and mild-to-moderate in severity but can lead to treatment discontinuation if titration is too rapid. 1
Semaglutide has a half-life of approximately 7 days, requiring 4-5 weeks to reach steady-state concentrations at each dose level. 3 This pharmacokinetic profile supports the 4-week titration intervals, allowing adequate time for drug accumulation and physiological adaptation before dose escalation.
Administration Guidelines
- Timing: Administer once weekly on the same day each week, at any time of day, with or without meals 1
- Route: Subcutaneous injection in the abdomen, thigh, or upper arm 4
- Missed doses: If less than 5 days since the missed dose, administer as soon as possible; if more than 5 days have passed, skip the missed dose and resume the regular schedule 1
Managing Missed Doses During Titration
- 2 consecutive doses missed: Resume at the same dose if previously well-tolerated, or consider lowering the dose based on clinical judgment 1
- 3 or more consecutive doses missed: Consider restarting the entire titration schedule from 0.25 mg 1
Dose Adjustments and Clinical Considerations
Some patients may achieve adequate glycemic control and weight loss at submaximal doses (0.5 mg or 1 mg weekly) and can continue long-term at these lower doses without escalating to 2 mg. 1 Monitor HbA1c reduction (expected 1.5-1.9% decrease) and weight loss (expected 5-10% from baseline) to determine if further dose escalation is necessary. 3, 5
Critical Safety Precautions
- Hypoglycemia risk: When combined with insulin or insulin secretagogues (sulfonylureas), reduce doses of these medications to minimize hypoglycemia risk 2, 1
- Renal impairment: No dose adjustment required for any degree of renal impairment, including end-stage renal disease 2, 1
- Pancreatitis: Discontinue immediately if pancreatitis is suspected and do not restart if confirmed 2
- Gastroparesis effects: Semaglutide delays gastric emptying and may impact absorption of oral medications requiring rapid onset 2, 3
Drug Interactions to Avoid
Do not use Ozempic concurrently with other GLP-1 receptor agonists or DPP-4 inhibitors. 1 This combination provides no additional benefit and increases the risk of adverse effects.
Common Pitfalls to Avoid
- Rushing titration: Advancing doses faster than every 4 weeks significantly increases gastrointestinal side effects and treatment discontinuation 1
- Inadequate patient education: Patients must understand that nausea is common during the first few weeks after each dose increase but typically resolves 2, 1
- Ignoring submaximal response: Not all patients require the maximum 2 mg dose; individualize based on therapeutic response 1
