The FDA has published 8 recalls involving Loxapine since 2012. The latest was reported on 30 May 2018. Most were for manufacturing (cgmp) deviations. Watson Laboratories has the most recalls in this group. Recalls usually affect specific lots, not every bottle on the market. Check the lot number on each recall page before acting.
Not on your own. Most recalls affect specific lots from one manufacturer, and stopping a prescription suddenly can be riskier than the defect. Check your lot number and NDC against the recall, then call the pharmacy that dispensed it for a replacement.
