  • Call the pharmacy before you run low. They can see which lot they dispensed to you and will usually swap it the same day.
  • Insurers do not normally count a recall replacement against a refill limit. If one is refused, ask the pharmacist to call it through as a recall override.
  • Over-the-counter products are refunded at the till like any other purchase; the recall notice on your phone is enough to explain the return.
  • If the manufacturer runs a direct reimbursement form, it will be linked from the official notice on this page.
