Gamunex-c (immune globulin) is an expensive drug used to treat primary humoral immunodeficiency, idiopathic thrombocytopenic purpura, and chronic inflammatory demyelinating polyneuropathy. It is more popular than comparable drugs and is currently only available as a brand drug. It may be covered by your Medicare or insurance plan, but some pharmacy coupons or cash prices could help offset the cost.
