Some medications are changed and broken down by the liver. Indole-3-carbinol might increase how quickly the liver breaks down some medications. Taking indole-3-carbinol along with some medications that are changed by the liver can decrease the effectiveness of some medications. Before taking indole-3-carbinol, talk to your healthcare provider if you take any medications that are changed by the liver.
