GLP-1 Medication Costs: Ozempic vs Wegovy vs Mounjaro

6 min read · Updated July 2026

GLP-1 medications like Ozempic, Wegovy, Mounjaro, and Zepbound have transformed weight loss and diabetes management. They've also created a pricing nightmare. The list price is over $1,000/month, but what you actually pay depends on your insurance, the pharmacy, and which coupon you use. Here's how to navigate it.

The Four Main GLP-1 Drugs

These drugs all work by mimicking GLP-1 (or both GLP-1 and GIP), hormones that regulate appetite and blood sugar. They differ in active ingredient, FDA approval, and cost:

  • Ozempic (semaglutide): FDA-approved for Type 2 diabetes. Often prescribed off-label for weight loss. Injectable, once weekly. List price: ~$968/month.
  • Wegovy (semaglutide): Same active ingredient as Ozempic, but FDA-approved for weight loss at a higher dose. List price: ~$1,349/month.
  • Mounjaro (tirzepatide): FDA-approved for Type 2 diabetes. Dual GIP/GLP-1 agonist — generally more effective than semaglutide for both blood sugar and weight loss. List price: ~$1,023/month.
  • Zepbound (tirzepatide): Same drug as Mounjaro, FDA-approved for weight loss. List price: ~$1,059/month.

Why Nobody Pays the List Price

The list price is a starting point, not what most people pay. Your actual cost depends on several layers:

  • Insurance coverage: If your plan covers GLP-1s, your copay might be $25-100/month. But many plans exclude weight-loss drugs entirely (though they may cover the diabetes versions).
  • Manufacturer savings cards: Novo Nordisk (Ozempic, Wegovy) and Eli Lilly (Mounjaro, Zepbound) offer savings cards that can reduce your cost to $25/month — but only if you have commercial insurance that covers the drug. Medicare and Medicaid patients aren't eligible.
  • Pharmacy coupons: GoodRx and similar services negotiate lower cash prices. These can reduce the cost to $800-950/month — still expensive, but 15-30% below list.
  • Compounded versions: When a drug is on the FDA shortage list (as semaglutide and tirzepatide have been), compounding pharmacies can legally produce copies at $300-500/month. Quality and dosing accuracy vary.

Insurance: Will They Cover It?

Insurance coverage for GLP-1s is a maze:

  • Medicare Part D: Covers GLP-1s for diabetes (Ozempic, Mounjaro) but not for weight loss (Wegovy, Zepbound) — unless you also have diabetes.
  • Medicaid: Varies by state. Some states cover GLP-1s for diabetes but not weight loss. Prior authorization is almost always required.
  • Employer plans: About 40% of large employers cover GLP-1s for weight loss. Smaller employers are less likely to. Check your formulary.
  • ACA marketplace plans: Essential health benefits include prescription drugs, but weight-loss drugs are frequently excluded.

Even when insurance covers the drug, they often require step therapy — you must first try and fail cheaper alternatives (metformin, other diabetes drugs) before they'll approve a GLP-1.

The prior authorization trap

Even with coverage, your doctor must submit a prior authorization (PA) request explaining why you need the drug. Insurance companies deny 20-30% of initial PA requests. If denied, you can appeal — but that process takes weeks. Ask your doctor to include your BMI, comorbidities, and failed previous treatments in the initial PA to improve approval odds.

Comparing Pharmacy Prices

Prices vary by $100-200/month between pharmacies, even within the same chain. Before filling your prescription:

  1. Check GoodRx, SingleCare, and the manufacturer's savings card for your specific drug and dose.
  2. Call 2-3 local pharmacies (including Costco, which often has low cash prices even for non-members).
  3. Check online pharmacies like Amazon Pharmacy or Mark Cuban Cost Plus Drugs.
  4. Compare the coupon price against your insurance copay — sometimes the coupon is cheaper.

The Bottom Line

  1. List prices are $970-1,350/month, but most patients pay far less through insurance, savings cards, or coupons.
  2. Manufacturer savings cards can bring your cost to $25/month — but only with commercial insurance that covers the drug.
  3. Check your formulary before getting your hopes up. Weight-loss drugs are frequently excluded.
  4. Compare prices across pharmacies. The difference can be $100-200/month.
  5. Compounded versions are a legal option during FDA shortages, at $300-500/month — but quality varies.
