My Husband Takes Edarbyclor 40/12.5 And When I Went To

My husband takes edarbyclor 40/12.5 and when I went to the pharmacy to refill his prescription, was told that the medication was on back order from the manufacturer. This was 4 weeks ago. I was wondering what the reason was for the back order and when it would be available again. Is it because the prices were going to be increased? His physician had some samples of Edarbi for him. My insurance company will NOT cover the cost of the Edarbi and I was quoted $200.00 for a month's supply. Any suggestions???
