Key Takeaways
- Zepbound is approved to help adults living with obesity, or who are overweight with a weight-related health condition, lose weight and keep it off.
- What you pay depends on your plan, your pharmacy and your prescription, so one price doesn't fit everyone.
- Your plan's drug list and coverage summary show most of what you'll pay, and you can ask for them any time.
- With LIV, there's no membership fee, and your provider checks in before every refill at no extra cost.
If you're ready to start Zepbound, you probably want to know what it will cost. If you have insurance, your plan's own documents answer most of that question.
What Zepbound Can Help With
Zepbound helps adults lose weight and keep it off, alongside a lower-calorie diet and more activity. It's for adults living with obesity, and for adults who are overweight and have a weight-related health condition. Its active ingredient, tirzepatide, acts on two hormone pathways involved in appetite: GIP and GLP-1. Approved tirzepatide injections reduce calorie intake, likely through their effects on appetite.
In a 72-week study on the Zepbound label, people taking the 15 mg dose lost an average of 20.9% of their starting weight. More than 9 in 10 of them lost at least 5%. Your own results may differ, which is why your provider reviews your progress with you before each refill and adjusts your plan as needed.
Why Does the Price Vary?
Your coverage matters as much as the medicine itself. What you pay comes down to four things:
- Your plan design. Your deductible, coinsurance and out-of-pocket maximum turn the same medicine into very different bills.
- The formulary tier. Coverage isn't all or nothing. The tier a drug is on decides your share.
- Prior authorization. If your plan requires approval first, completing that step can be the difference between a covered prescription and full price.
- Which product is prescribed. Zepbound and compounded tirzepatide are different products, and your provider reviews which one fits you.
The Plan Documents That Shape Your Cost
| Document | What it tells you | Where to get it |
|---|---|---|
| Formulary | Whether your plan covers the drug, and on which tier | Your plan's drug list, published by the plan |
| Prior authorization criteria | Whether approval is needed before a prescription is covered | Your plan, usually alongside the formulary |
| Summary of Benefits and Coverage | Your deductible, coinsurance and out-of-pocket maximum, in plain language | Your insurer or job-based plan, any time you ask |
Work through them in that order. Each one tells you what to look for in the next.
What Is a Formulary?
A formulary is a list of prescription drugs covered by a prescription drug plan or another insurance plan offering drug benefits. It's also called a drug list.
For Zepbound, check whether it's on the list and which tier it's on, since the tier sets your share of the cost. Lists change, so look at your plan's current one rather than last year's.
What Is Prior Authorization?
Prior authorization is approval from a health plan that may be required before you get a service or fill a prescription, in order for it to be covered.
Plans usually publish their criteria. If you check them before your evaluation, you can tell your provider what your plan will want to see.
What Is the Summary of Benefits and Coverage?
It's your plan's own summary of what it covers and what you pay, and you have a right to it. Insurance companies and job-based health plans must provide you with a short, plain-language Summary of Benefits and Coverage, along with a uniform glossary of the terms used in health coverage. It's built so you can compare plans on the same basis, and you can ask your insurer or group health plan for a copy any time.
It carries your deductible, your coinsurance and your out-of-pocket maximum. Those three numbers, plus the formulary tier, are most of your answer.
How a LIV Plan Works
A LIV plan has no membership fee. Every plan includes:
- A telehealth visit with a licensed provider
- Zepbound, at the strength your provider prescribes
- Provider review before every refill, at no extra cost
- Instructions with your shipment
- Free shipping, with delivery usually 3 to 5 days after approval
- Your care team, whenever you need them
HOW A LIV PLAN WORKS
From first visit to your door.
- Telehealth visit A licensed provider gets to know your health history and goals
- Labs and review Your required labs, then a decision on whether Zepbound fits
- Delivered, then followed Free shipping, and a check-in before every refill
No membership fee.
You're billed on the schedule you choose, and you can skip a shipment or cancel anytime from your account. Labs are required for this treatment, and a licensed provider reviews your health history and results before prescribing.
LIV also offers compounded tirzepatide, mixed for you by a licensed pharmacy. Your provider reviews which option fits your health history and goals, and the compounded tirzepatide guide explains how the two differ.
Side Effects and Safety Notes
The most common side effects listed on the Zepbound label are stomach-related: nausea, diarrhea, vomiting, constipation, abdominal pain and indigestion.
Zepbound isn't right for everyone. Your provider will ask about:
- Thyroid history: a personal or family history of medullary thyroid cancer or MEN 2.
- Past conditions: pancreatitis, gallbladder disease or kidney problems.
- Other medicines: especially diabetes medicines that can lower blood sugar.
- Allergies: any serious allergic reaction to a medicine.
Let your provider know promptly about severe or lasting stomach pain, ongoing vomiting or signs of dehydration.
Start With Your Evaluation
Bring your plan documents and your questions about cost. When you're ready, an evaluation is the next step: a licensed provider reviews your history and required labs, then decides with you whether Zepbound or another option fits.
Frequently Asked Questions
How much does Zepbound cost without insurance?
Without insurance, you pay the self-pay price for the prescription and plan you choose. With LIV, there's no membership fee. Your plan includes the medicine, shipping and ongoing support, with provider review before every refill at no extra cost.
Does insurance cover Zepbound?
That depends on your plan's formulary and its prior authorization criteria, both of which the plan publishes. The tier a drug is on then decides your share.
What is prior authorization and why does it matter?
It's approval a plan may require before a prescription is covered. A drug can be on your formulary and still cost full price at the counter if that step hasn't been completed.
Where do I find my own numbers?
Start with the Summary of Benefits and Coverage, which your insurer or job-based plan must give you in plain language, and which you can request any time. Then check the formulary and the prior authorization criteria the plan publishes.
What is Zepbound approved for?
Zepbound is approved for weight loss and long-term weight maintenance in adults with obesity, or overweight and a weight-related health condition, alongside a lower-calorie diet and more activity. It's also approved for moderate to severe obstructive sleep apnea in adults with obesity.
Where does the 20.9% figure come from?
From Study 1 on the Zepbound label, which enrolled 2,539 adults with obesity, or excess weight with a related health condition, who didn't have type 2 diabetes (Jastreboff et al., NEJM, 2022). The results are for the 15 mg and placebo groups, not every dose: average weight loss was 20.9% on Zepbound 15 mg versus 3.1% on placebo, and 90.9% versus 34.5% lost at least 5% of their starting weight. Everyone had support with a lower-calorie diet and more activity, doses were increased gradually, and the estimates include people who stopped treatment. The study dose isn't a dosing recommendation, and individual results vary.
Is compounded tirzepatide the same as Zepbound?
They share an active ingredient, but they're different products. Compounded tirzepatide is mixed by a licensed pharmacy for one person. Compounded medicines aren't FDA-approved, and the FDA doesn't review their safety, effectiveness or quality before they're marketed.
What does the boxed warning on Zepbound say?
The Zepbound label carries a boxed warning about thyroid C-cell tumors. Tirzepatide caused these tumors in rats; it isn't known whether Zepbound does in people. Zepbound isn't for anyone who has had, or has a family member who has had, medullary thyroid carcinoma (MTC), or anyone with MEN 2 or a serious allergy to tirzepatide. Tell your provider about a lump in your neck, trouble swallowing, shortness of breath or hoarseness that doesn't go away.
The label also says Zepbound isn't recommended for severe gastroparesis, and to tell your care team before any procedure with anesthesia or deep sedation. The label also notes that routine blood tests (calcitonin) or thyroid ultrasound are of uncertain value for catching these tumors early.
