I've heard the maximum for mesalamine rectal is 4 grams a day and the rowasa enemas I'd get here in the states were 4g each. Your 3 gram approach is a good start, especially if you're not sure if you're mesalamine-intolerant. The rectals also include sulfates, another potential allergen. If you have an allergic reaction then it'll be a dramatic worsening of symptoms (frequency can get exponentially worse).
I hope the mesalamine does the trick for you. Only one way to find out, try. I believe Salofalk and pentasa enemas are available in higher doses, if you get some response but need something stronger. Good luck!
