See Contraindications. Potentiates simvastatin; limit simvastatin dose to 20mg/day. May potentiate cyclosporine, tacrolimus, lithium; monitor levels. Potentiated by CYP3A4 inhibitors; may need dose reduction. Antagonized by NSAIDs (including selective COX-2 inhibitors); may impair renal function (monitor). Dual inhibition of the renin-angiotensin system with ARBs, ACEIs, or aliskiren may increase risk of hypotension, hyperkalemia, renal function changes; monitor closely. Concomitant aliskiren in renal impairment (CrCl <60mL/min): not recommended. Consider taking at least 4hrs before colesevelam HCl dose. Monitor BP with CYP3A4 inducers.
