Riomet (Metformin Hydrochloride Oral Solution) Recalled

November 28, 2017

Samples of the diabetes medication were contaminated.

Sun Pharmaceutical Industries announced that it is voluntarily recalling two lots of Riomet (metformin hydrochloride oral solution). The drug was found to be contaminated with Scopulariopsis brevicaulis.

Riomet is indicated to treat type 2 diabetes in adults and children over the age of 10. It is packaged in 118 mL (4 fl oz) and 473 mL (16 fl oz) bottles. The affected lots are products with the NDC Code 10631-206-01 Lot A160031A, Exp.: 01/2018, and NDC 10631-206-02 Lot: A160031B, Exp.: 01/2018. The lots were distributed nationwide.

The contamination was discovered during sample preparation for the Antimicrobial Preservative Effectiveness Testing (AMPET), which was performed as part of the 12-month stability study interval.

Using the contaminated drugs could result in a risk of infection, especially in immunocompromised patients. The most likely route of infection is through the respiratory tract, where it could cause pneumonia, sinusitis, and other infections. Sun Pharmaceuticals has so far not received any adverse events related to the recall.
