Wegovy (Semaglutide) for Weight Loss: Treatment Protocol

Primary Recommendation

For adults with BMI ≥30 kg/m² or BMI ≥27 kg/m² with at least one weight-related condition (hypertension, dyslipidemia, type 2 diabetes), initiate Wegovy (semaglutide 2.4 mg) as a once-weekly subcutaneous injection, combined with a reduced-calorie diet (500 kcal deficit) and minimum 150 minutes weekly of physical activity. 1, 2

Patient Eligibility Criteria

FDA-Approved Indications:

  • BMI ≥30 kg/m² without additional requirements 1, 2
  • BMI ≥27 kg/m² with at least one weight-related comorbidity including hypertension, dyslipidemia, type 2 diabetes, or obstructive sleep apnea 1, 2, 3

Absolute Contraindications:

  • Personal or family history of medullary thyroid cancer 1, 4
  • Multiple endocrine neoplasia syndrome type 2 (MEN2) 1, 4
  • History of severe hypersensitivity reaction to semaglutide 4

Dosing and Titration Schedule

Standard Titration Protocol (16-week escalation): 1

  • Weeks 1-4: 0.25 mg weekly
  • Weeks 5-8: 0.5 mg weekly
  • Weeks 9-12: 1.0 mg weekly
  • Weeks 13-16: 1.7 mg weekly
  • Week 17 onward: 2.4 mg weekly (maintenance dose)

Administration: Once-weekly subcutaneous injection in abdomen, thigh, or upper arm 4

Dose Adjustments:

  • Patients unable to tolerate 2.4 mg may remain on 1.7 mg 5
  • Slow titration minimizes gastrointestinal adverse effects 1
  • No dose adjustment required for renal or hepatic impairment 4

Mandatory Lifestyle Interventions

Wegovy must be combined with: 1, 2

  • Dietary modification: 500 kcal reduction below daily requirements
  • Physical activity: Minimum 150 minutes per week of moderate-intensity exercise
  • Resistance training: To preserve lean body mass during weight loss
  • Behavioral counseling: For sustained lifestyle modification

Critical Point: Pharmacotherapy as monotherapy does not meet FDA approval criteria and substantially reduces efficacy 2

Expected Outcomes and Efficacy

Weight Loss Results: 1, 5, 6

  • Mean weight loss: 14.9-17.4% at 68 weeks in non-diabetic patients
  • 10% weight loss: Achieved by 64.9% of patients
  • 15% weight loss: Achieved by 55.6% of patients
  • 20% weight loss: Achieved by 38.5% of patients
  • Long-term (24 months): Mean weight loss of 20.4% maintained 6

Cardiometabolic Benefits: 1

  • 20% reduction in cardiovascular death, nonfatal MI, or nonfatal stroke (HR 0.80) in patients with established cardiovascular disease
  • Improvements in blood pressure, lipid profiles, and insulin sensitivity
  • HbA1c reduction of approximately 1.4-1.48% in patients with type 2 diabetes

Monitoring Schedule

Initial Titration Phase (First 16 weeks): 1, 2

  • Every 4 weeks: Assess gastrointestinal tolerance, weight loss progress, blood pressure, and adverse effects

Maintenance Phase (After week 16): 1, 2

  • Every 3 months minimum: Monitor weight, blood pressure, cardiovascular risk factors, medication adherence
  • Evaluate treatment efficacy at 12-16 weeks on maintenance dose (2.4 mg)

Treatment Discontinuation Criteria: 1, 2

  • <5% weight loss after 3 months at therapeutic dose predicts poor long-term response
  • Significant safety or tolerability issues at any time

Adverse Effects and Management

Common Gastrointestinal Effects (occur in 53-84% of patients): 1, 5

  • Nausea (most frequent)
  • Vomiting
  • Diarrhea
  • Constipation
  • Abdominal pain

Management Strategies: 1

  • Slow dose titration every 4 weeks
  • Reduce meal size
  • Limit alcohol and carbonated beverages
  • Symptoms typically mild-to-moderate and decrease over time

Serious Adverse Events (rare but important): 1

  • Pancreatitis: Monitor for persistent severe abdominal pain; discontinue if suspected
  • Gallbladder disease: Cholelithiasis and cholecystitis reported
  • Delayed gastric emptying: Creates aspiration risk during anesthesia

Concomitant Medication Adjustments

If patient is taking: 1

  • Insulin: Reduce dose by 20% when initiating semaglutide to prevent hypoglycemia
  • Sulfonylureas: Discontinue or reduce dose by 50% due to increased hypoglycemia risk
  • DPP-4 inhibitors: Discontinue before starting semaglutide (no additional benefit)
  • Other GLP-1 receptor agonists: Absolute contraindication to combine

Perioperative Management

For elective surgery requiring anesthesia: 1

  • Discontinue semaglutide at least 3 weeks (three half-lives) before surgery due to delayed gastric emptying and aspiration risk
  • Retained gastric contents documented even after extended fasting periods (24.2% of semaglutide users vs 5.1% controls) 1
  • Consider gastric ultrasound pre-operatively to assess residual gastric contents

Long-Term Treatment Considerations

Duration of Therapy: 1

  • Lifelong treatment typically necessary to maintain weight loss and cardiometabolic benefits
  • Sudden discontinuation results in regain of one-half to two-thirds of lost weight within 1 year
  • Early responders (≥5% weight loss at 3 months) should continue long-term therapy

Cost Considerations: 1

  • Average wholesale price: approximately $1,557-$1,619 per 30-day supply
  • Insurance authorization may be challenging, particularly for obesity management without diabetes

Special Populations

Patients with Cardiovascular Disease: 1

  • Prioritize semaglutide 2.4 mg due to proven cardiovascular benefit (20% reduction in MACE)
  • Particularly valuable in patients with established atherosclerotic cardiovascular disease

Patients with Type 2 Diabetes: 1

  • Offers dual benefits: improved glycemic control and weight loss
  • Weight loss appears lower in individuals with diabetes (4-6.2%) compared to non-diabetic patients (6.1-17.4%)

Patients with Chronic Kidney Disease: 4

  • No dose adjustment required across all CKD stages, including end-stage renal disease
  • Reduces albuminuria by 20.6% at 68 weeks

Critical Pitfalls to Avoid

  1. Do not prescribe as monotherapy without concurrent lifestyle modifications 2
  2. Do not continue beyond 12 weeks at maintenance dose if <5% weight loss achieved 2
  3. Do not ignore perioperative aspiration risk from delayed gastric emptying 1
  4. Do not combine with other GLP-1 receptor agonists or DPP-4 inhibitors 1
  5. Do not fail to adjust insulin/sulfonylurea doses when initiating treatment 1

Alternative Considerations

If semaglutide is unavailable or not tolerated: 1

  • Tirzepatide 15 mg weekly: Superior weight loss (20.9% at 72 weeks) but lacks proven cardiovascular outcomes data
  • Liraglutide 3.0 mg daily: More modest weight loss (5.2-6.1%) but daily injection required

Note: Wegovy is specifically the 2.4 mg formulation approved for obesity management; lower-dose semaglutide formulations (Ozempic) are FDA-approved only for type 2 diabetes treatment, though they produce weight loss as well. 1
