Primidone Tablets

Class III — Low risk. Unlikely to cause harm, but violates FDA regulations.

Why it was recalled

Cross Contamination with Other Products: due to a potential for cross-contamination with Acemetacin API due to an issue at the API manufacturer.

Cause type: Cross-contamination

Traces of another drug - most often penicillin - got into the product from shared equipment or facilities. Even trace penicillin can trigger a severe allergic reaction in someone who was never meant to receive it. All cross-contamination recalls.

Low risk, still worth a check. Class III means the product is unlikely to cause harm but breaks an FDA rule (often labeling). If your lot matches, your pharmacy will normally swap it; there is no need for alarm.
