Getting semaglutide starts with a prescription from a licensed healthcare provider, either through an in-person visit or a telehealth consultation. There is no legal way to buy it over the counter or without a prescription. The process involves meeting specific medical criteria, getting a prescription written, navigating insurance or paying out of pocket, and filling it at a pharmacy.
Who Qualifies for a Prescription
Semaglutide is FDA-approved under three brand names, each for different uses. Wegovy is approved for weight management, Ozempic for type 2 diabetes, and Rybelsus is an oral tablet also approved for type 2 diabetes. For weight loss specifically, the FDA criteria require either a BMI of 30 or higher, or a BMI of 27 or higher with at least one weight-related health condition such as high blood pressure, type 2 diabetes, high cholesterol, sleep apnea, or heart disease. Pediatric patients aged 12 and older with obesity also qualify for Wegovy.
Wegovy also carries a separate approval for reducing the risk of heart attack, stroke, and cardiovascular death in adults who have established heart disease along with obesity or overweight.
One important group of people cannot use semaglutide at all: anyone with a personal or family history of medullary thyroid cancer, or a rare condition called multiple endocrine neoplasia syndrome type 2. This carries the FDA’s strongest warning, a black box label, on all semaglutide products.
In-Person vs. Telehealth Visits
You can get a semaglutide prescription through your primary care doctor, an endocrinologist, or a weight management specialist. If you already have an established relationship with a provider and meet the criteria, this is often the most straightforward path. Your doctor can assess your full medical history, check for contraindications, and submit insurance paperwork.
Telehealth platforms are another option. These services connect you with a provider for a virtual consultation where they review your health status, discuss your weight loss goals, and determine whether semaglutide is appropriate. If you’re prescribed the medication, the prescription is sent electronically to a pharmacy for pickup or delivery. Many of these platforms also help coordinate the prior authorization process with your insurer. The quality of telehealth services varies, so look for platforms staffed by board-certified physicians or nurse practitioners who specialize in weight management rather than services that seem to guarantee a prescription to anyone who signs up.
What Insurance Companies Require
Most insurance plans that cover semaglutide for weight loss require prior authorization, which means your provider needs to submit documentation proving you meet specific clinical criteria before the insurer will pay. This process can take anywhere from a few days to a few weeks.
A representative example of what insurers look for comes from Cigna’s coverage policy. For initial approval, you typically need to be 18 or older, have a qualifying BMI (30 or above, or 27 or above with a weight-related comorbidity), and show that you’ve already tried behavioral changes and dietary modifications for at least three months. The medication must be used alongside a reduced-calorie diet and behavioral modification, not as a standalone treatment.
For continued coverage, many insurers require you to demonstrate at least 5% weight loss from your starting point. If you don’t hit that threshold, your insurer may deny renewal. Keep this in mind: your provider will likely need to document your progress at follow-up visits to support ongoing authorization.
Coverage varies significantly between plans. Some employer-sponsored plans exclude weight loss medications entirely. Medicare Part D historically has not covered anti-obesity drugs, though this has been an evolving policy area. Medicaid coverage depends on your state. Call your insurer directly and ask whether GLP-1 medications for weight management are a covered benefit before starting the process.
What It Costs Without Insurance
The list price for both Ozempic and Wegovy sits around $1,000 or more per month. Novo Nordisk, the manufacturer, has introduced direct pricing programs that bring costs down. Through one such program, the two lowest doses of Ozempic and Wegovy (0.25 mg and 0.5 mg) are available for $199 per month. Higher doses, including the 1 mg dose of Ozempic and all Wegovy doses, cost $349 per month through the manufacturer’s program. The 2 mg dose of Ozempic is not included in either pricing tier.
Costco has also partnered with Novo Nordisk to offer low-dose Ozempic and Wegovy for $499 per month out of pocket. These prices apply when you’re paying cash, without routing through insurance. Manufacturer savings cards and patient assistance programs may further reduce costs for people who qualify, typically those without insurance coverage for the drug.
Injection vs. Oral Tablet
Ozempic and Wegovy are both once-weekly injections given under the skin, typically in the stomach, thigh, or upper arm. They come in prefilled pens with small needles, so you don’t need to draw up doses yourself. Rybelsus is a daily oral tablet, but it comes with strict instructions: take it on an empty stomach with only a sip of plain water, then wait at least 30 minutes before eating, drinking anything else, or taking other medications. This timing requirement matters because food and liquid interfere with absorption.
Keep in mind that Rybelsus is only approved for type 2 diabetes, not weight loss. If your goal is weight management and you prefer not to inject, you’ll want to discuss this with your provider, but the FDA-approved option for that indication is Wegovy.
Why Compounded Semaglutide Is Risky
With high prices and previous supply shortages driving demand, compounded versions of semaglutide have flooded the market. These products are not FDA-approved and carry real safety concerns. Semaglutide is no longer on the FDA’s drug shortage list, which means the legal basis for pharmacies to compound it has narrowed considerably.
The FDA has flagged several specific problems. Some compounded products contain salt forms of semaglutide (semaglutide sodium or semaglutide acetate) that are chemically different from the active ingredient in approved drugs. The agency has no data confirming these alternatives work the same way or are equally safe. Multiple adverse event reports, some requiring hospitalization, have been linked to dosing errors with compounded injectables. These errors happen both because patients miscalculate doses from multi-use vials and because providers sometimes prescribe doses beyond what the approved labeling supports.
Quality control is another concern. The FDA has received complaints about compounded semaglutide arriving warm or without adequate cold packing, which can degrade the drug. Injectable semaglutide requires refrigeration. Perhaps most alarming, the agency has identified fraudulent products with fake pharmacy names on the labels, as well as products sold “for research purposes” or marked “not for human consumption” that are clearly being marketed to consumers with dosing instructions.
If you’re offered semaglutide from an online source that doesn’t require a prescription, charges significantly below market rates, or ships products that aren’t refrigerated, treat that as a red flag.
Steps to Get Started
- Check your BMI and health history. Use an online BMI calculator to see if you meet the 30 (or 27 with comorbidities) threshold. Note any weight-related conditions you’ve been diagnosed with.
- Call your insurance. Ask specifically whether Wegovy or Ozempic is on your formulary and what prior authorization requirements apply.
- Schedule a visit. Book with your primary care provider, an obesity medicine specialist, or a telehealth platform. Bring documentation of any previous weight loss efforts, as insurers often require evidence of prior behavioral modification.
- Start at a low dose. Semaglutide is prescribed on a gradual dose escalation schedule to reduce side effects like nausea. You’ll begin at the lowest dose and increase over several months.
- Plan for follow-ups. Expect regular check-ins with your provider, both for managing side effects and for meeting insurer requirements to continue coverage.
