Why it was recalled
Cross contamination with other products: API contaminated with trace amounts of Acemetacin API.
Something got into the product
A physical or chemical contaminant was found — glass or metal fragments, or a solvent that should not be there.
This is a manufacturing or quality failure, not a finding that the medicine is unsafe to take — across every recall we hold, none was issued for that reason. It does not mean the batch was harmless.
