Drug Interaction Report

Bile acid binding resins such as cholestyramine, colestipol, and colesevelam may interfere with the absorption of fludrocortisone and reduce its levels in the bloodstream. This may make the medication less effective in treating your condition. To minimize the possibility of interaction, it is recommended that you separate the dosing times of the bile acid binding resin and other oral medications. If you are taking cholestyramine or colestipol, you should take fludrocortisone at least 1 hour before or 4 to 6 hours after the cholestyramine or colestipol dose. If you are taking colesevelam, you should take fludrocortisone at least 4 hours before the colesevelam dose, or separate the dosing times by as much as possible if a 4 hour interval is not achievable. Talk to your doctor or pharmacist if you have any questions or concerns. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.
