Allergy Medication Recall: The Life-Threatening Mix-Up You Need to Know About

A select number of allergy medications have been voluntarily recalled after cross-contamination with a drug used for heartburn and severe acid reflux. 

"Unique Pharmaceutical Laboratories is voluntarily recalling four lots of Cetirizine Hydrochloride Tablets USP 5 mg to the consumer level due to cross contamination with Ranitidine," an FDA notice reads.

The contamination could be life-threatening, specifically for those with hypersensitivity to certain ingredients, the FDA says.
