I use Canasa. I remember when I first picked up the prescription, I had to pay about 150 dollars for 60 suppositories - 75 sounds pretty average. I had insurance and it was still $150 for some reason.
I now order from Canada and it's about 120 for 60 suppositories with no insurance. They call it Salofalk in Canada.
Do you use it morning and night? I was using it just before bed for a while and it wasn't helping so much, now I am using it 2x a day and I am feeling a lot better, no more blood or mucus but still some D... I also take Asacol.
When I first took Canasa, I think my UC was very mild and responded well in just a few days. Now it takes a lot longer to get things under control.
I would give it a little more time or try 2x a day if you're only using it once.
I spoke to Axcan Pharma and they have an assistance program. You should check out their site. If you qualify you can get free drugs.
