How this impacts providers: Members may reach out to providers upon receipt of a recall letter from their health plan and/or pharmacy. Pharmacies may dispense another manufacturer’s metformin due to this recall.
Next steps for providers: Providers should stay vigilant about additional recalls related to metformin. The Federal Drug Agency (FDA) is investigating if other manufacturers may be impacted by this same impurity.
