Some insurance companies that do not cover Avandamet will cover the two medications in Avandamet separately. In other words, even if Avandamet is not covered, you may have coverage for Avandia® (rosiglitazone) and metformin (Fortamet, Glucophage, Glucophage XR, Glumetza, or Riomet). You would need two separate prescriptions from your healthcare provider, and you would likely need to pay two copays. For some people, this option may be more cost effective, although it would result in needing to take more tablets per day.
