Sun Pharmaceutical Industries, Inc., has recalled two lots of metformin hydrochloride oral solution (Riomet), 500 mg/5 mL, due to fungal contamination, the FDA announced on Nov. 24.

During testing, the affected lots were found to be contaminated with Scopulariopsis brevicaulis, which poses infection risks, most likely in the respiratory tract and in immunocompromised patients. The medication is packaged in 4-oz and 16-oz bottles, and recalled products have a January 2018 expiration date. No related adverse events have been reported, according to the manufacturer.
