Getting a GLP-1 prescription starts with meeting specific weight criteria and finding a provider willing to prescribe, but the process involves more steps than a single doctor’s visit. You’ll need to qualify based on your BMI, complete bloodwork, navigate insurance requirements (or decide to pay out of pocket), and work through a dose escalation schedule that takes months. Here’s what the full process looks like.
Who Qualifies for a GLP-1 Prescription
The FDA-approved weight loss GLP-1s have clear eligibility thresholds based on body mass index. You qualify if you have obesity, defined as a BMI of 30 or higher. You can also qualify at a lower BMI of 27 to 29.9 if you have at least one weight-related health condition, such as high blood pressure, high cholesterol, type 2 diabetes, or obstructive sleep apnea.
These criteria apply to adults and, for semaglutide (Wegovy), to adolescents aged 12 and older with obesity. A separate indication covers adults with established cardiovascular disease and either obesity or overweight, where the medication is prescribed to reduce the risk of heart attack, stroke, or cardiovascular death.
Your provider will calculate your BMI at the visit. If you’re close to the threshold, your weight at that specific appointment is what counts. Some telehealth platforms use self-reported height and weight, though most require verification.
Where to Get a Prescription
You have several options for the prescribing visit itself, and which route you choose affects cost, speed, and insurance compatibility.
Your primary care doctor is the most straightforward option if you have an established relationship. They already know your medical history, can order labs through your insurance, and can document the weight-related conditions needed for prior authorization. Many PCPs now prescribe GLP-1s routinely.
Obesity medicine specialists and endocrinologists are another route, particularly if your primary care doctor is hesitant to prescribe or if you have complex medical needs. The trade-off is longer wait times for an appointment, sometimes weeks to months.
Telehealth platforms have become one of the fastest-growing channels for GLP-1 prescriptions. Companies like Ro, Hims/Hers, and Found offer virtual consultations specifically for weight management. These visits are typically quicker to schedule and sometimes cheaper upfront, but they may not coordinate as easily with your insurance for the medication itself. Some telehealth providers have also historically prescribed compounded versions of these drugs, which is worth understanding separately.
Bloodwork and Medical Screening
Before writing a prescription, most providers will order baseline lab work. This isn’t just a formality. The results help rule out contraindications and establish a health snapshot to track your progress against. Common panels include blood sugar and HbA1c (your average blood sugar over the past two to three months), a cholesterol and lipid panel, kidney function markers, and liver enzymes. These tests screen for conditions that frequently overlap with obesity, including undiagnosed type 2 diabetes, early kidney problems, and liver disease.
Your provider will also review your medical history for specific contraindications. GLP-1 medications carry an FDA boxed warning and cannot be prescribed to anyone with a personal or family history of medullary thyroid carcinoma or a genetic condition called Multiple Endocrine Neoplasia syndrome type 2 (MEN2). A history of pancreatitis is another red flag that most providers will screen for carefully.
The Insurance Authorization Process
This is where the process slows down for many people. Most insurance plans require prior authorization before covering a GLP-1 for weight management, and the requirements vary significantly between insurers.
Common Requirements
Insurers typically want documentation that you’ve already tried to lose weight through other means. A common requirement is evidence of a six-month trial of lifestyle changes, including dietary modifications and increased physical activity, before medication approval. Your provider needs to document this in your chart, so if you’ve been working on weight loss with your doctor’s knowledge, that history matters.
Step therapy is another common hurdle. This means your insurer may require you to try a less expensive or preferred medication first before approving the one your doctor requested. For example, some plans require documented failure on a preferred GLP-1 before covering a non-preferred one. “Therapeutic failure” typically means you didn’t achieve meaningful results at the maximum approved dose while also maintaining lifestyle changes, and your provider documented your adherence.
Some insurers require that weight-related comorbidities be actively documented in your medical record, not just mentioned at the prescribing visit. If you have high blood pressure or sleep apnea, make sure those diagnoses appear in your chart with supporting data.
Coverage Exclusions
Not all insurance covers GLP-1s for weight loss at all. Many state Medicaid programs are moving to exclude coverage for obesity indications specifically. Some employer-sponsored plans also carve out weight loss medications. Medicare has historically not covered anti-obesity medications, though a bridge program now exists for certain eligible beneficiaries. If your plan doesn’t cover weight loss drugs, your options are paying out of pocket, using manufacturer savings programs, or exploring whether you qualify under a different indication like type 2 diabetes.
Paying Out of Pocket
The list price for brand-name GLP-1 medications runs roughly $1,000 to $1,300 per month without insurance. That’s a significant barrier, but there are ways to reduce the cost.
Both major manufacturers offer savings programs for commercially insured patients. If your insurance covers the drug but leaves you with a high copay, these programs can reduce your out-of-pocket cost substantially. Eligibility rules vary, and these savings cards generally don’t apply to government insurance like Medicare or Medicaid.
Some patients turn to compounded versions of these medications, which have historically been available at lower cost through compounding pharmacies. However, the regulatory landscape here has shifted. Both semaglutide and tirzepatide are no longer listed on the FDA’s drug shortage list, which changes the legal basis under which compounding pharmacies could produce copies. The FDA has been clarifying its enforcement policies as brand-name supply stabilizes, so the availability of compounded versions is not guaranteed going forward.
What Happens at the First Appointment
The prescribing visit itself is relatively straightforward once you’ve met the eligibility criteria. Your provider will review your labs, confirm your BMI and any comorbid conditions, and discuss your weight history. Expect questions about previous weight loss attempts, your eating patterns, and your activity level. This isn’t gatekeeping. Providers ask because the medications work best alongside behavioral changes, and insurers often require this documentation.
If you’re approved, you won’t start at the full dose. GLP-1 medications use a gradual dose escalation schedule to minimize side effects, particularly nausea. For semaglutide, you’ll typically start at a low weekly dose and increase every four weeks over a period of about 16 to 20 weeks before reaching the maintenance dose. Your provider will schedule follow-up visits or check-ins during this ramp-up period to monitor how you’re tolerating the medication and adjust if needed.
You’ll be taught how to self-inject, which sounds intimidating but uses a small pre-filled pen with a tiny needle. Most people inject in the abdomen, thigh, or upper arm once per week. The injection itself takes seconds.
How Long Until You Fill the Prescription
The timeline from first deciding you want a GLP-1 to actually injecting the first dose varies widely. If you go through a telehealth platform and pay cash, it can happen within a week or two, assuming labs come back clean. If you’re going through insurance with prior authorization, expect the process to take anywhere from two to six weeks, and potentially longer if your initial request is denied and your provider needs to appeal.
Pharmacy availability has improved. Earlier shortages of both semaglutide and tirzepatide created months-long waits, but supply has largely stabilized as of 2025. Your pharmacist can check real-time stock, and most can order the medication within a few days if it’s not on the shelf.
If your prior authorization is denied, your provider’s office can file an appeal. Common reasons for denial include insufficient documentation of prior weight loss attempts, missing lab work, or not meeting the insurer’s specific BMI threshold with documented comorbidities. A denial isn’t necessarily the end of the road, but it does add time. Ask your provider’s office how they handle appeals and what additional documentation might help.
