FOSRENOL is a phosphate binder indicated to reduce serum phosphate in patients with end stage renal disease (ESRD).
Management of elevated serum phosphorus levels in end stage renal disease patients usually includes all of the following: reduction in dietary intake of phosphate, removal of phosphate by dialysis and reduction of intestinal phosphate absorption with phosphate binders.
DOSAGE AND ADMINISTRATION
Divide the total daily dose of FOSRENOL and take with or immediately after meals. The recommended initial total daily dose of FOSRENOL is 1500 mg. Titrate the dose every 2-3 weeks until an acceptable serum phosphate level is reached. Monitor serum phosphate levels as needed during dose titration and on a regular basis thereafter.
In clinical studies of ESRD patients, FOSRENOL doses up to 4500 mg were evaluated. Most patients required a total daily dose between 1500 mg and 3000 mg to reduce plasma phosphate levels to less than 6.0 mg/dL. Doses were generally titrated in increments of 750 mg/day.
Chew or crush tablets completely before swallowing. Do not swallow intact tablets.
Consider crushing tablets completely for patients with poor dentition.
Consider potential drug interactions when prescribing FOSRENOL [see DRUG INTERACTIONS].
