Hi and welcome to the forum. A typical dose of apriso is 1,500 milligrams per day (or 4 capsules, each capsule being 375 milligrams) taken all in the morning. It's a lower dose than lialda, as clinical trials showed apriso to be as effective at lower doses.
I'd get the apriso copay savings card as well:
