Canasa suppository assistance programs?

I am currently taking Canasa suppositories 1000 mg once a day.  I have no insurance coverage.  I was receiving assistance through the pharmaceutical company but it has expired.  I've scoured the internet for any other assistance programs and only came up with one that saves me $60.  This medication costs $550 a month.  There is no way I can afford it.  Does anyone have any suggestions?  I've checked into Xubex and Partnership for prescription assistance but am not getting anywhere.   Does anyone know if there is a generic available?  Or where to get this medication cheaper?  It really helps my ulcerative colitis so I'm worried if I go off it I will experience a flare up.  I'm open to any and all suggestions and help.

Thanks.

Thank you notsosicklygirl. I did try this link and it only gives me $60 off the prescription. This would be great if I had health insurance but it only lowered the price to $500 a month. I even looked at Canadian prices on this med and they were still out of my price range. If anyone else has any ideas please let me know. I'm contacting me doctor to see if there is something cheaper she can prescribe me. I wish they would come out with a generic on this medication. Thank you for your help.

I thought the Canasa PAP made it so you pay only $40 max out of pocket?

AZ gave a good suggestion. Northwest pharmacy is wellknown and trusted. I haven't ordered from there but I have used Canada drugs and they have good prices as well and a generic.
