Wait, don't panic. You're on SSDI and Medicare right? Check into the patient assistance program. http://www.needymeds.org/papforms/asspae2306.pdf

I'm not sure that form is the right one but it was the only one I found and I am pretty sure assure has something to do with Rexulti.

You may not technically qualify but when you are on Medicare and have a lower income they make exceptions. I get all of my name-brand meds (4 different meds from 3 different companies) on patient assistance exceptions. They also are very lenient with new meds my pdoc tells me. But really, just do the application, have your pdoc do their part and write a note explaining limited income, Medicare doesn't cover, unable to afford $900/month and send it in. Nearly 100% chance they'll approve you.

I get $60,000 worth of Seroquel XR this way every year.....
