The list of recalled blood pressure medication is expanding due to an impurity classified as a human carcinogen discovered in more lots of medication.
"In the case of losartan recently that one the patient should stop taking it immediately," said pharmacy manager of Ladd Family Pharmacy Robert Boulier.
The newest medication in question is losartan potassium tablets, supplied from both Camber Pharmaceuticals and Torrent Pharmaceuticals have recalled nearly 100 lots collectively. Eighty-seven of those coming from Camber as of Thursday.
However, you can't check your prescription yourself to see if you have an affected prescription.
"It does not go on the prescription label if they get it in a vial from their pharmacy, the lot number does not go on there, that's the challenge, really the only place to find the lot number is on the stock bottle it originally came from," said Boulier.
Still, pharmacies are having issues identifying which medications are coming from tainted lots.
"You know a patient got dispensed a medication a year ago, I can tell you what manufacturer made it, but I won't know what lot and expiration are associated with that fill," Said Boulier.
Every recall has varying degrees of severity. This recall is one that pharmacists are saying, to take seriously.
"It's one that we're actually being directed to reach out to the customers, so we're compiling a list of people who've received that medication from that manufacturer," said Boulier.
Ladd Family Pharmacy says they have medication they can swap, and losartan from different manufacturers that have not been recalled.
Ladd doesn't currently have any of the bad lot numbers on their shelves.
