The Food and Drug Administration (FDA) has posted a recall notification for 2 lots of Riomet (metformin HCl oral solution; Sun Pharmaceuticals) 500mg/5mL due to the possibility that the liquid may be contaminated with Scopulariopsis brevicaulis. Specifically, the affected Riomet includes product with NDC # 10631-206-01 Lot A160031A, Exp: 01/2018, and NDC # 10631-206-02 Lot: A160031B, Exp: 01/2018. 

Use of contaminated product could result in infection, especially for immunocompromised patients. The recall notice states that the most plausible portal of entry of Scopulariopsis brevicaulis, a multi-resistant fungal pathogen, is the respiratory tract. This could potentially lead to pneumonia, sinusitis and disseminated infections.

At this time, the company has not received reports of adverse events related to this recall. Clinicians are urged to report adverse reactions related to the use of this product to the FDA’s MedWatch program.
