To get tirzepatide for weight loss, you need a prescription from a licensed medical provider who confirms you meet specific BMI and health criteria. The FDA approved tirzepatide under the brand name Zepbound for chronic weight management in November 2023, and you can obtain it through your primary care doctor, an obesity medicine specialist, or a telehealth platform. The process involves a medical evaluation, a prescription, and often a prior authorization battle with your insurance company.
Who Qualifies for a Prescription
Zepbound is approved for adults who meet one of two profiles. The first is a BMI of 30 or higher, which is the clinical threshold for obesity. The second is a BMI of 27 or higher combined with at least one weight-related health condition such as high blood pressure, high cholesterol, type 2 diabetes, obstructive sleep apnea, or cardiovascular disease.
Your BMI alone doesn’t guarantee a prescription. The FDA label specifies that tirzepatide should be used alongside a reduced-calorie diet and increased physical activity, not as a standalone treatment. Providers will review your full medical history, current medications, allergies, and whether you’re pregnant or planning to become pregnant before writing a prescription.
Where to Get a Prescription
You have three main routes: your primary care physician, an obesity medicine or endocrinology specialist, or a telehealth service. Any licensed prescriber can write the prescription, so you don’t necessarily need a specialist. If your primary care doctor is unfamiliar with the medication or hesitant to prescribe it, an obesity medicine physician is your best next step.
Telehealth platforms have made access significantly easier. Walgreens Weight Management, for example, offers virtual consultations starting at $49 per visit with no subscription required, available in over 25 states. A provider reviews your medical history by video, determines whether treatment is clinically appropriate, and can prescribe Zepbound to be picked up at a local pharmacy. Several other telehealth companies offer similar services, though you should verify that any platform you use connects you with a licensed provider in your state and sends prescriptions to a legitimate pharmacy.
What Insurance Requires Before Covering It
Most insurance plans that cover Zepbound require prior authorization, which means your provider must submit documentation proving you meet specific criteria before the insurer agrees to pay. This is where the process often stalls.
A representative example comes from Cigna’s policy, which is typical of major insurers. For initial approval, you generally need to show that you’ve tried behavioral modification and dietary changes for at least three months, that your BMI meets the thresholds above, and that you’ll continue diet and exercise alongside the medication. The initial approval period is usually around eight months.
For continued coverage after that initial period, insurers typically require proof that you’ve lost at least 5% of your starting body weight. If you haven’t hit that mark, your insurer may deny renewal. Your provider handles most of this paperwork, but be prepared for the process to take days or even weeks. Ask your doctor’s office about their experience with prior authorizations for GLP-1 medications, since some practices have staff dedicated to navigating these requests.
Many insurance plans still don’t cover weight loss medications at all. Medicare currently does not cover Zepbound for weight management, though legislation to change this has been proposed. Check your specific plan’s formulary before assuming coverage.
What You’ll Pay
The retail price of Zepbound without insurance is substantial. Eli Lilly, the manufacturer, offers a savings card that brings the cost down considerably depending on your situation. If your commercial insurance covers Zepbound, the savings card can reduce your copay to $25 per month. If you don’t have coverage or your plan excludes the medication, the savings card still applies but at higher price points: $299 per month for the starter dose (2.5 mg), $399 per month for the 5 mg dose, and $499 per month for all higher strengths.
These savings-card prices represent a significant discount from the full list price and are available directly through the manufacturer’s website. The card does not work with government insurance programs like Medicare, Medicaid, or Tricare.
How the Dosing Schedule Works
Tirzepatide is a once-weekly injection you give yourself under the skin, typically in your abdomen, thigh, or upper arm. Everyone starts at the lowest dose of 2.5 mg per week for the first four weeks. This introductory period lets your body adjust and minimizes side effects. After that, your provider increases the dose gradually. The maximum dose is 15 mg per week, but not everyone needs to go that high. Your provider will adjust based on how your body responds and what side effects you experience.
The drug works by activating two gut hormone receptors (GLP-1 and GIP) that reduce appetite and slow digestion, so you feel full sooner and stay full longer. This is a different mechanism than older weight loss drugs, and the dual-receptor approach is part of why tirzepatide has shown strong results in clinical trials.
Side Effects to Expect
Gastrointestinal side effects are the most common reason people struggle with tirzepatide, especially during dose increases. In the large clinical trials (called SURMOUNT), nausea affected 25% to 33% of people depending on the dose, compared to about 10% on placebo. Diarrhea occurred in roughly 19% to 23% of participants, and vomiting in 8% to 13%. These numbers come from the highest-quality trial data available, involving thousands of participants.
For most people, nausea and digestive issues are worst in the first few weeks at each new dose and improve with time. Eating smaller meals, avoiding high-fat foods, and staying hydrated can help. If side effects are severe, your provider may keep you at a lower dose for longer before increasing. A small percentage of people discontinue treatment because of GI symptoms, so it’s worth knowing this is a possibility before you start.
Compounded Tirzepatide: Risks and Restrictions
You may have seen compounded versions of tirzepatide advertised online at lower prices. Compounded drugs are custom-mixed by pharmacies and are not FDA-approved for safety, effectiveness, or quality. The FDA has issued warnings about fraudulent compounded tirzepatide products circulating in the U.S., including products with fake pharmacy names on the labels.
The legal landscape for compounded tirzepatide has shifted recently. Tirzepatide is no longer on the FDA’s drug shortage list, which significantly restricts when compounding pharmacies can legally produce it. Under current rules, a traditional compounding pharmacy (operating under Section 503A) can only fill four or fewer prescriptions of a compounded copy per month when the brand-name version is commercially available. Larger outsourcing facilities (Section 503B) cannot compound tirzepatide from bulk ingredients at all unless it appears on the FDA’s shortage list or a specific approved-use list, neither of which currently includes tirzepatide.
If you’re considering a compounded version because of cost, understand that you’re accepting unknown quality and potency in exchange for a lower price. The FDA is clear that compounded drugs should only be used when an FDA-approved option can’t meet a patient’s medical need. If a provider or online service offers compounded tirzepatide without discussing these limitations, that’s a red flag.
Steps to Get Started
- Check your BMI and health history. Use an online BMI calculator with your current height and weight. If you’re at 30 or above, or 27 and above with a related condition like high blood pressure or sleep apnea, you likely meet the basic criteria.
- Review your insurance formulary. Call the number on the back of your insurance card or check the online drug formulary to see if Zepbound is covered. Ask specifically about prior authorization requirements and any step-therapy rules that might require you to try other treatments first.
- Schedule a medical visit. This can be with your primary care doctor, a specialist, or a telehealth provider. Bring documentation of any previous weight loss attempts, as insurers often require evidence of prior behavioral modification.
- Apply for the manufacturer savings card. Do this before filling your first prescription so the discount is applied at the pharmacy counter.
- Plan for the prior authorization timeline. If your insurance requires it, expect the approval process to take one to three weeks. Some pharmacies will notify you when the authorization comes through.
