I normally take two 500mg capsules of pentasa 3 times per day but my gi doc told me that if it is easier for me I could take the same total amount in 2 divided doses, so that would be 3 in the morning and 3 in the evening. He said it was better if smaller amounts go to the small intestine more frequently but if it means forgetting, then I should do it twice. So it seems like it is ok to go over the 1 gram in one dose but I'm not sure I would double it without calling to check.
10 years, many tests, 3 gi doctors, Pentasa 1000mg 3x day
