This is not your price. NADAC is the national average that retail pharmacies pay to buy the drug, from the Medicaid survey for the week of Nov 11, 2026. What you pay adds the pharmacy's markup and dispensing fee and depends on your insurance or any discount card. "For 30" is shown only for products priced per tablet or capsule. Brand prices here are before any rebates.
Medicare Part D spending by product, from the latest annual file (2024).
In 2024, Medicare Part D plans and their members paid $74.5 million for the 2 products below. That is down 13% from $86.1 million in 2020.
| Product | 2024 spending | People | Per prescription | Per person, year | 2020 spending |
|---|---|---|---|---|---|
| Clonazepam Clonazepam | $71.1 million | 1,314,154 | $8.03 | $54.07 | $81.5 million |
| Klonopin Clonazepam | $3.4 million | 2,323 | $229.03 | $1,465.87 | $4.6 million |
Spending is the gross amount paid at the pharmacy by Part D plans and patients, before manufacturer rebates, which can be large for brand drugs. The same person can use more than one product, so people are not added up across rows. A dash means the file suppresses a small number or has no figure for that year.

A recall covers specific lots from one company, not every bottle of the drug. Records include combination products and compounded versions that name this ingredient. Class I is the most serious: use could cause serious harm. Class II may cause temporary or reversible harm. Class III is unlikely to cause harm. To check a bottle, match the lot number on the label. See the live list. Do not stop a medicine because of a recall without asking your pharmacist.
