What consumers should do
Because FDA considers adverse health consequences unlikely for a Class III recall, the recommended action is still to stop using the product and follow the recalling firm's instructions, since a recall means the product did not meet FDA requirements. Specifically, check whether the product in your possession matches the description on file with FDA -- Primidone Tablets, USP, 250 mg, 100-count bottle, RX only, Manufactured by: Lannett Company, Inc., Marketed by: GSMS, Incorporated, Camarillo, CA 93012. NDC 51407-638-01 -- and the recall number D-0535-2026. If it matches, stop using or distributing it and contact Golden State Medical Supply Inc. or the point of purchase for return or replacement instructions. Retailers and distributors holding affected inventory should quarantine it and follow the firm's written recall notice.

The recall is tracked under FDA recall number D-0535-2026 and carries a status of Ongoing as of the most recent FDA enforcement report. This classification reflects FDA's assessment of the product defect described above, not a prediction about any specific patient outcome. FDA maintains a public enforcement report database so that consumers, physicians, and purchasers can look up the exact product identifiers involved before deciding what to do. Recall status can change while FDA and the recalling firm continue corrective actions, so checking the firm's own notice for the most current guidance is recommended. Adverse events believed to be related to a recalled product can be reported to FDA's MedWatch program, which FDA uses to monitor safety signals after a recall is opened.
