The information at Drugs.com is not a substitute for medical advice. ALWAYS consult your doctor or pharmacist.

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 (7)].
