The pricing information disclosed represents the WAC price, which represents the manufacturer’s published catalog or list price for a drug product to wholesalers as reported to third-party drug pricing publishers. WAC does not represent actual transaction prices and does not include discounts, rebates or reductions in price. The price paid by patients to acquire the products listed is often different than the WAC prices listed, and most patients do not pay WAC. How much a patient will pay will depend on the patient’s insurance coverage. To learn the exact cost of a prescription, patients should contact their health insurance company or preferred pharmacy. Pricing information listed does not imply safety or efficacy of the product, and no comparisons should be made.

The listing of generic products in the disclosure forms does not imply that such products are interchangeable with the Astellas-marketed product or have the same efficacy or safety. Please refer to each product's U.S. Food and Drug Administration (FDA)-approved prescribing information for further information.
