Byetta (exenatide) is a prescription injectable medication used to help control blood sugar in people with type 2 diabetes. Its price can vary quite a bit depending on a few factors—how much you get in each vial, how many vials you’ll need each month, your insurance coverage, and whether you qualify for manufacturer savings programs.
Typical price ranges (2024)
| Dosage form | Approx. out‑of‑pocket cost for a single 0.5 mg vial (no insurance) |
|-------------|--------------------------------------------------------------|
| 0.5 mg 0.5 mL (single‑dose) | $70 – $90 |
| 0.5 mg 1.5 mL (double‑dose) | $100 – $130 |
| 0.5 mg 3 mL (triple‑dose) | $140 – $180 |
| 1.0 mg 1 mL (single‑dose) | $120 – $150 |
| 1.0 mg 2 mL (double‑dose) | $160 – $200 |
| 1.0 mg 3 mL (triple‑dose) | $190 – $240 |
These figures come from pharmacy pricing websites and are averages for retail pharmacies. Your actual cost could be lower if:
- Insurance: Most commercial plans cover Byetta under the diabetes drug tier. Copay amounts can range from $10 to $50 per prescription, depending on your plan’s tier structure.
- Manufacturer Assistance: Eli Lilly offers a savings card program. Eligible patients can get up to a 30–40 % discount on the retail price.
- Pharmacy Discount Programs: Programs like GoodRx or OptumRx can sometimes give you a coupon for a few dollars off each vial.
- Bulk or Mail‑Order Pharmacy: Ordering a 30‑day supply can sometimes bring the per‑month cost down.
What you’ll need to know for budgeting
- Prescribed dose – Most patients start at 0.5 mg once weekly, then increase to 1 mg once weekly after 4 weeks if needed. That means you’ll likely need 1–2 vials per month, so budget $140–$360/month before insurance.
- Insurance details – Check your formulary list for “Byetta” and see which tier it falls under. Some plans require prior authorization or step‑therapy before approving the drug.
- Savings cards – Go to Eli Lilly’s drug‑specific savings page or ask your pharmacist about any available coupons.
- Pharmacy choice – If you have a preferred pharmacy, ask them if they run any discount programs; sometimes they can offer a “pharmacy‑specific” discount that’s not listed online.
Bottom line
Out‑of‑pocket, a monthly supply can cost anywhere from roughly $140 to $360, depending on dose and the number of vials. With insurance, the cost is usually a small copay (often $10–$50) or a modest coinsurance (e.g., 20 % of the drug’s list price). If cost is a concern, talk with your doctor or pharmacist about applying for a manufacturer savings card or checking whether a different medication with similar efficacy might be cheaper under your plan.
