The least meds but with full coverage would be mesalamine oral and rectal (enemas). You're already on the oral...add the enemas.
I agree. Good for you for trying to get off biologics. Mesalamines like sulfasalazine can help you maintain remission and if needed sulfasalazine can be reinforced by mesalamine rectal meds such as Rowasa.
And compared to biologics with their sometimes serious side effects, mesalamines are proven to help protect you from cancer,
