What to do about Drug safety

Radnostix — This is an FDA enforcement action. The summary above is the agency’s own description of what went wrong.

  3. Keep the carton; the lot number is often printed only on the outer pack.
  4. Report side effects you think the product caused to FDA MedWatch.

Refunds and replacements

With medicines, a replacement supply matters more than cash, and that is what pharmacies are set up to provide.

  • Ask the dispensing pharmacy for a like-for-like replacement from an unaffected lot. This is the fastest route and usually costs nothing.
  • For a mail-order or online pharmacy, use the recall line listed on this page rather than the general support queue.
  • If the recall voided a fill you had already paid for, your insurer will normally authorise a replacement ahead of schedule. Quote the recall number.
  • If you paid out of pocket, ask for a refund of the co-pay or purchase price and keep the receipt the pharmacy issues.
