Who Qualifies for a GLP-1 Prescription? BMI, Conditions & Criteria

The eligibility criteria for a GLP-1 prescription depend on which drug, which indication, and whether you're going through insurance or paying out of pocket. Here's exactly what you need to know.

One of the first questions people ask is whether they qualify for a GLP-1 prescription. The answer depends on three things: the specific drug, the indication it's being prescribed for, and whether you're using insurance or paying cash through a telehealth provider.

FDA-approved criteria for weight management

Wegovy (semaglutide) and Zepbound (tirzepatide) are the two drugs specifically approved for chronic weight management in the US. The FDA criteria for both are:

  • BMI of 30 or higher, OR
  • BMI of 27 or higher plus at least one weight-related health condition

Weight-related conditions that satisfy the second criteria include type 2 diabetes, high blood pressure, high cholesterol, obstructive sleep apnea, and cardiovascular disease — among others. Your prescriber makes the final determination.

FDA-approved criteria for type 2 diabetes

Ozempic (semaglutide) and Mounjaro (tirzepatide) are approved for type 2 diabetes management. If you have type 2 diabetes, BMI thresholds are less relevant — the indication is the diagnosis itself. These drugs are often prescribed when lifestyle changes and metformin haven't achieved adequate blood sugar control.

Off-label prescribing

Physicians can prescribe any drug off-label for indications not listed in the FDA approval. In practice, some prescribers will prescribe diabetes-approved formulations (Ozempic, Mounjaro) for weight management in patients who meet the spirit of the clinical criteria but don't have a diabetes diagnosis. Off-label prescribing is legal and common — but insurance almost never covers it.

Telehealth providers and cash pay

Telehealth platforms that prescribe compounded or brand GLP-1s for cash often apply similar criteria to the FDA thresholds, but some are more flexible. Expect to complete a medical intake form covering your weight, BMI, health history, medications, and any contraindications. A clinician reviews this and makes the prescribing decision. You typically do not need an in-person visit.

Who cannot take GLP-1 medications

Key contraindications include:

  • Personal or family history of medullary thyroid carcinoma (MTC) or Multiple Endocrine Neoplasia type 2 (MEN 2)
  • Pregnancy or planning to become pregnant
  • Severe gastrointestinal disease (e.g. gastroparesis)
  • History of pancreatitis (requires careful evaluation)
  • Serious hypersensitivity to the drug or its components

Your prescriber will screen for these. Be thorough and accurate in your intake history — these contraindications exist for real reasons.

What documentation you may need

For insurance-covered prescriptions, expect to provide: recent lab work, a documented weight history, prior treatment attempts (diet, exercise, sometimes prior medications), and evidence of qualifying conditions. Prior authorization processes vary significantly by insurer.

Qualification criteria are guidelines — your prescriber applies clinical judgment to your specific situation. This is educational content, not a determination of your eligibility.

Frequently Asked Questions

Why do most diets fail long-term?

After diet-induced weight loss, the body mounts a sustained compensatory response: ghrelin stays elevated, leptin stays suppressed, resting metabolic rate decreases beyond mass loss, and NEAT drops automatically. The Biggest Loser follow-up study found contestants' metabolic rates remained ~500 kcal/day below prediction six years later, even as most regained significant weight. These changes work against maintenance regardless of effort.

How much weight loss is realistic on GLP-1 medications?

STEP 1 (semaglutide 2.4mg) showed 14.9% average weight loss at 68 weeks. SURMOUNT-1 (tirzepatide 15mg) showed 20.9% at 72 weeks — the highest ever recorded in a randomized pharmaceutical trial. These are means: approximately 30% of semaglutide users and 57% of high-dose tirzepatide users achieve ≥20% weight loss. Around 5-10% are non-responders.

Are GLP-1 medications more effective than diet and exercise alone?

Substantially more effective. In the STEP trials, semaglutide plus lifestyle counseling produced 14.9% weight loss versus 2.4% for lifestyle counseling alone — approximately a 6-fold difference. The key mechanism is that GLP-1 medications reduce the biological drive to eat, making caloric deficit sustainable rather than requiring constant active resistance against elevated hunger hormones.

What does long-term sustainable weight management look like?

National Weight Control Registry data from people who maintained ≥30 lbs weight loss for ≥1 year identifies consistent patterns: ~1 hour/day of physical activity, regular self-monitoring, consistent dietary patterns (including regular breakfast), and high dietary vigilance. With continued GLP-1 medication, two-year data shows ~15% weight loss maintained without significant rebound — suggesting pharmacological support may be part of a realistic long-term strategy for many people.
