Unique Pharmaceutical Laboratories pulled lot Nos. GY825029, GY825030, GY825031 and GY825032 of 100-count bottles of Cetirizine Hydrochloride 5 mg because the tablets might have ranitidine.
“For consumers with a hypersensitivity to the ingredients in ranitidine,” the company recall notice said, “there is a reasonable probability that ingestion of cetirizine tablets contaminated with ranitidine could result in serious adverse events including severe hypersensitivity reactions and anaphylaxis that manifests as hypotension, dyspnea, difficulty swallowing, throat and facial edema, generalized pruritic, urticaria, and loss of consciousness, which are all life-threatening.”
Ranitidine was sold over-the-counter under the brand name Zantac. Cetrizine is the generic version of Zyrtec.
