A recall doesn't mean your pills are affected

Drug recalls are issued by lot (specific batches, identified by lot numbers / NDC) — not for every bottle of PRIMIDONE ever made. To know if yours is involved, match the lot codes on the recall below against your bottle, or ask your pharmacist. Do not stop a prescribed medication because of a recall without talking to your pharmacist or prescriber — stopping can be more dangerous than the recall. The Class is the FDA's risk judgment (Class I = reasonable probability of serious harm or death), not a measurement that harm occurred; most recalls are voluntary and Class II/III.

Why it was recalled

Cross contamination with other products: API contaminated with trace amounts of Acemetacin API. 5
Cross Contamination with Other Products: due to a potential for cross-contamination with Acemetacin API due to an issue 1
