My husband takes Carbidopa/levodopa Extended Release 4 times daily. The last time we refilled his prescription, we were told that some manufacturerrs had stopped making the drug. We were able to get his filled for a 90 day supply. Now, we need to refill again, and no pharmacy had it! And the mail order people we use say that they cannot get it either. We have a 17 day supply, and will be calling the dr first thing Monday morning. Anybody switched from the ER to something else? He cannot take regular Carbidopa/ levodopa, as he gets stroke-like symptoms. His dosage of ER is 25/100, and he takes 3 tabs 4 times a day. Help!!!
