See Contraindications. Dual inhibition of the renin-angiotensin system with ARBs, ACEIs, or aliskiren may increase risk of hypotension, hyperkalemia, renal function changes; monitor closely. Avoid concomitant aliskiren in renal impairment (CrCl <60mL/min). Take 4hrs before colesevelam HCl dose. Concomitant simvastatin: max simvastatin dose 20mg/day. May potentiate cyclosporine, tacrolimus, lithium; monitor levels. Potentiated by CYP3A4 inhibitors; may need dose reduction. Adjust antidiabetic, antigout medications. ACTH, corticosteroids increase hypokalemia risk. Orthostatic hypotension potentiated by alcohol, barbiturates, narcotics. May be antagonized by, and renal toxicity potentiated by NSAIDs, including COX-2 inhibitors; monitor renal function in elderly and/or volume-depleted. Reduced absorption with bile acid resins (eg, cholestyramine, colestipol). Potentiates other antihypertensives. May potentiate nondepolarizing muscle relaxants. May antagonize norepinephrine. Monitor BP with CYP3A4 inducers. May interfere with parathyroid tests.
