Ozempic and Zepbound are two of the most popular GLP-1 medications — but they work differently, cost differently, and have different coverage pathways. If you're trying to decide between them based on price, here's the complete breakdown.
Price Comparison at a Glance
| Cost Category | Ozempic (Semaglutide) | Zepbound (Tirzepatide) |
|---|---|---|
| Retail list price | $935/mo | $1,059/mo |
| Manufacturer self-pay | $349/mo (NovoCare) | $299/mo (LillyDirect vials) |
| Compounded version | from $149/mo | from $179/mo |
| With commercial insurance | $25–150 copay | $25–150 copay |
| Medicare (July 2026+) | ~$50 copay | ~$50 copay |
| 12-month cost (compounded) | $1,788–2,988 | $2,148–3,588 |
What's the Difference Between Ozempic and Zepbound?
These medications look similar on the surface — both are weekly injections that help with weight loss — but they have fundamentally different mechanisms.
Ozempic (Semaglutide)
Ozempic is a GLP-1 receptor agonist. It mimics the GLP-1 hormone, which slows gastric emptying, reduces appetite, and improves blood sugar control. Ozempic is FDA-approved specifically for type 2 diabetes, though it's commonly prescribed off-label for weight management. Wegovy is the same drug (semaglutide) at a higher dose, approved specifically for weight loss.
Zepbound (Tirzepatide)
Zepbound is a dual GIP/GLP-1 receptor agonist — it targets both the GIP and GLP-1 receptors. This dual mechanism has produced superior weight loss results in head-to-head trials. Zepbound is FDA-approved specifically for chronic weight management. Mounjaro is the same drug (tirzepatide) approved for type 2 diabetes.
Tirzepatide (SURMOUNT trials): Average weight loss of ~21% of body weight over 72 weeks at the highest dose.
Tirzepatide produced roughly 40% more weight loss than semaglutide in comparable trial populations.
Cost Per Pound of Weight Loss
When comparing value, the raw monthly price doesn't tell the whole story. If tirzepatide produces more weight loss, the cost per pound lost may actually be lower despite the higher monthly price.
| Metric | Compounded Semaglutide | Compounded Tirzepatide |
|---|---|---|
| Monthly cost (compounded) | ~$149 | ~$179 |
| Avg. weight loss (% body weight) | ~15% | ~21% |
| Lbs lost (200-lb person) | ~30 lbs | ~42 lbs |
| 12-month cost | $1,788 | $2,148 |
| Cost per pound lost | ~$60 | ~$51 |
On a per-pound basis, tirzepatide may actually deliver better value despite costing more per month. Of course, individual results vary — these are averages from clinical trials.
Which Has Better Insurance Coverage?
Insurance coverage varies significantly between the two medications and depends on why they're prescribed:
- For type 2 diabetes: Both Ozempic and Mounjaro (the diabetes formulation of tirzepatide) are commonly covered. Ozempic has broader formulary coverage because it's been on the market longer.
- For weight loss: Coverage is more limited. Roughly 40% of commercial plans cover either Wegovy or Zepbound for weight management. Prior authorization is almost always required.
- Medicare: Starting July 2026, the Medicare Part D bridge program will cover GLP-1s for weight loss with a temporary $50/month copay cap through December 2026.
