How GLP-1 Injections Work
GLP-1 receptor agonists are medications that mimic glucagon-like peptide-1, a natural hormone involved in glucose regulation and satiety. They are prescribed for individuals with type 2 diabetes (Ozempic® ) or obesity(WeGovy®) and function by enhancing insulin secretion, delaying gastric emptying, and promoting satiety.
A typical dose escalation protocol may include:
- Month 1: 0.25 mg weekly
- Month 2: 0.5 mg weekly
- Month 3: 1 mg weekly
- Month 4: 1.7 mg weekly
- Month 5+: 2.4 mg weekly (often the maintenance dose)
Semaglutide, a GLP-1 receptor agonist (RA), has a long half-life (~1 week), allowing for weekly administration and potential flexibility for bi-weekly adjustments in some cases, when eligible based on individual health (Srinivasareddy, 2024).
The Concept of Every Other Week GLP-1 Injections
Once patients stabilize on their maintenance dose, some healthcare providers may consider a shift to an every-other-week injection regimen. This potential adjustment is based on individual treatment response and provider discretion.
Although not the standard, this model may be considered for those who:
- Have established tolerance and stability with the medication
- Prefer reduced injection frequency
- Require treatment flexibility for lifestyle compatibility
This transition must be accompanied by close clinical monitoring to ensure continued efficacy and safety.

Weekly vs. Every Other Week Dosing: A Comparison
Dosing Frequency |
Characteristics |
Weekly |
Administered every 7 days
- Standard for dose escalation and maintenance
- Offers consistent drug levels and easier monitoring
|
Every Other Week |
Taken every 14 days
- May be considered for stable patients
- Offers scheduling flexibility, requires stricter adherence
|
Weekly dosing has demonstrated high effectiveness for both glycemic control and weight management in real-world studies (Tan et al., 2024), but provider-guided alternate dosing may be appropriate for select individuals. The study specifically evaluated two forms of semaglutide: oral semaglutide (commercially known as Rybelsus®) and subcutaneous semaglutide (formulations consistent with Ozempic® or Wegovy®).
Potential Benefits of Every Other Week GLP-1 Maintenance Dosing
Some non-clinical benefits that may be discussed in a provider consultation include:
- Reduced injection burden and improved convenience
- Better adherence for individuals with injection fatigue
- Simplified medication routines for those on stable regimens
However, these potential advantages must be weighed against the risk of reduced efficacy or loss of therapeutic benefit if drug levels become subtherapeutic.
Considerations and Potential Risks
Shifting to bi-weekly dosing introduces certain clinical risks:
- Possible reduced or fluctuating drug plasma concentrations
- Increased likelihood of symptom recurrence between doses
- Greater reliance on strict adherence to timing
- Need for intensified symptom tracking and follow-up
- Potential variability in individual pharmacokinetics
Only a licensed healthcare provider can evaluate the safety of such a change, particularly in patients with comorbidities, such as renal or hepatic impairment (Frias, 2018).
Who Might Be a Candidate for Every Other Week GLP-1 Dosing
This approach may be considered for patients who:
- Have successfully completed the initial titration phase
- Demonstrate treatment stability and symptom control
- Do not have complex metabolic or chronic diseases requiring tighter regulation
- Express a strong preference for reduced injection frequency
Candidate selection is based on personalized medical assessments, with ongoing adjustments as necessary.

How to Discuss Every Other Week Dosing with Your Provider
If you're considering a bi-weekly regimen, connect with your licensed healthcare provider. Topics to cover include:
- Your experience with weekly dosing and symptom control
- Any logistical or personal challenges with weekly injections
- Willingness to adhere strictly to a new schedule
- Understanding the potential risks and benefits
A provider-guided transition is essential for monitoring efficacy and safety.
Final Thoughts
Weekly dosing of GLP-1 receptor agonists remains the gold standard due to its established safety and effectiveness. However, in some cases, bi-weekly dosing may be a viable alternative for individuals with stable responses and specific lifestyle needs. This transition must be made under the careful evaluation of a licensed healthcare provider and include close monitoring.
