You might also ask your doctor's office if they have any samples while you evaluate your options. When I was first put on Pentasa in October, my office sent me home with over two months of pills (at 4 grams a day). I had already hit my deductible for the year, so my cost at the time was zero anyway (I won't be as "lucky" this year, even if I hit my deductible), but my doctor's office told me to save them for this year so I don't have to pay so soon.
Maybe they have some samples they can give you, as even a short time would save some money, especially while you're observing the effectiveness.
The downfall, of course, was having to open each blister pack -- 1 pill per pack -- 8 pills a day -- 2 months worth. :rof:
