What is the recommended follow-up period in months for patients initiated on Glucagon-like peptide-1 (GLP-1) agonists?

Follow-Up Schedule for Patients on GLP-1 Receptor Agonists

Patients initiated on GLP-1 receptor agonists should be evaluated every 3-6 months after reaching their maintenance dose, with more frequent monitoring (monthly or every 4 weeks) during the initial titration phase. 1

Initial Titration Phase (First 3-4 Months)

During dose escalation, patients require closer monitoring to assess tolerability and early response:

• Evaluate patients monthly (every 4 weeks) during titration to assess gastrointestinal tolerance, weight loss progress, blood pressure changes, and signs of pancreatitis or gallbladder disease 1, 2
• For faster-onset medications, the first follow-up can occur as early as 4 weeks after initiation 1
• Assess treatment efficacy at 12-16 weeks (approximately 3-4 months) on the maximum tolerated therapeutic dose to determine if continuation is appropriate 1, 2

Maintenance Phase (After Reaching Target Dose)

Once patients achieve their maintenance dose and demonstrate treatment response:

• Reassess at least every 3-6 months to evaluate continued weight loss progress, cardiovascular risk factors, medication adherence, and adverse effects 1
• Monitor quarterly (every 3 months minimum) after week 16 for weight, blood pressure, cardiovascular risk factors, and gastrointestinal tolerance 2
• Medication regimen and medication-taking behavior should be reevaluated at regular intervals (every 3-6 months) and adjusted as needed 1

Critical Decision Points

Early Response Assessment (3 Months)

• If weight loss is <5% after 3 months at therapeutic dose, discontinue the medication and consider alternative approaches 1, 2
• Early responders (≥5% weight loss after 3 months) should continue medication long-term unless clinical circumstances suggest otherwise 1, 2

Treatment Intensification

• If patients fail to achieve glycemic targets after approximately 3 months at maximum tolerated dose, consider adding or intensifying other glucose-lowering medications 1
• Recommendation for treatment intensification should not be delayed for individuals not meeting treatment goals 1

Special Monitoring Considerations

Concurrent Insulin Therapy

• For patients on insulin, check fasting glucose daily and pre-meal glucose before each meal for the first 2 weeks, with 2-hour post-meal glucose after the largest meal daily and bedtime glucose nightly 2
• If any glucose reading <70 mg/dL, immediately reduce insulin further by 10-20% 2

Long-Term Maintenance

• After achieving weight loss goals, assess patients at least quarterly for weight stability, cardiovascular risk factors, and medication tolerance 2
• Monthly weight monitoring is recommended for the first 6 months after discontinuation if stopping therapy 2

Common Pitfalls to Avoid

• Do not delay follow-up beyond 3-6 months in the maintenance phase, as this may miss treatment failure or adverse effects 1
• Do not wait longer than 3-4 months to assess initial treatment response, as early non-responders are unlikely to benefit from continued therapy 1, 2
• Do not neglect blood pressure monitoring, as weight loss may necessitate antihypertensive medication adjustment 2
• Ensure patients understand that lifelong treatment is typically necessary, as discontinuation results in regain of one-half to two-thirds of lost weight within 1 year 2
