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.

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.
