The RX insurance companies usually won't give you an answer for the MS tier 4 meds until they have authorization - which is a script from your doctor - then it's an expensive co-pay!!!!!! until you hit catastrophic - then it's less - I was quoted $2500 a month for Copaxone - with that as a monthly bill until I get over the gap which they are increasing -ends up being $6,000 to $7,000 a year - then the other meds are added on too - makes you want to bang your head against the wall -

Since you're on Medicare - I'm assuming that's the cost while you're in the donut hole. My mom is on medicare and got some excellent isupplemental nsurance and Rx coverage through AARP. We looked into several programs and it looked like this one was pretty good. She pays very little for her meds now. She's on a ton of different ones (no DMD though) for her MS symptoms. Might be worth looking into. The price for the coverage seemed fairly reasonable to me on a monthly basis.

My RX insurance is a very reasonable amount each month - but then the Copaxone kicks in - just spoke with them last week and was quoted $1500 1st month - $2580 2nd month - another $2580 3rd month - now out of donut hole - then $150 to $200 each month thereafter - then add in the Fosamax (which went generic - would have thought the price would go down - but no) - the Provigil - the baclofen - the diazapam (which no insurance seems to cover) and the omeprazole and that's a hefty RX bill for someone on SS with supplementals -
