What to do about Drug safety

Golden State Medical Supply Inc. — The product was withdrawn from distribution. Whether your own pack is affected comes down to the lot number.

  1. Check the lot number on your pack against the codes listed above.

  4. Keep the carton; the lot number is often printed only on the outer pack.

What the company owes you

A recalled medicine is the manufacturer’s cost to carry, not yours or your pharmacist’s.

  • The purchase price or co-pay is refundable, and so is the cost of returning the product if they ask you to ship it.
  • Ask the pharmacy to handle the claim where they can — they process recall returns in bulk and it saves you the correspondence.
  • Keep the carton, the leaflet and the pharmacy label together until the claim is closed.
  • Costs beyond the price of the medicine need to go to the company directly, in writing, with the recall number quoted.
