Watson Recalls Zenchent Tablets Due to Potential Hydrochlorothiazide Contamination
Watson Laboratories is recalling Zenchent tablets because certain lots may be contaminated with trace amounts of Hydrochlorothiazide (HCTZ).
The agency’s classification
FDA (Drugs): Class II
Class II is a situation in which use of or exposure to a violative product may cause temporary or medically reversible adverse health consequences, or where the probability of serious adverse health consequences is remote.
This is the agency’s own classification, taken from its notice. The severity score below is our assessment, not the agency’s. How recall classes work
What this means for you
Our assessment, not the agency’s: severity 2/5 (Moderate).
Minor labeling or packaging issue, or a voluntary precautionary recall. Risk of harm is low but real — follow the manufacturer's instructions.
Our severity reasoning: The recall is classified as FDA Class II, but the source text describes the hazard as 'potentially' contaminated with 'trace amounts' and does not report any illnesses or injuries, fitting the criteria for a voluntary precautionary recall or low-risk contamination.
