In brief: May interact

"When these 2 medicines are taken together, your body may process your birth control faster. What might happen: The effects of your birth control pills may decrease and cause breakthrough bleeding, spotting, or pregnancy.
The effects of the interaction may last for several weeks after you stop taking your rifamycin medicine." REF: http://www.webmd.com/drugs/2/drug-1744/rifampin-oral/details/list-
