Table of contents:

Fosrenol is a prescription medicine used to lower elevated serum phosphate levels in patients with end-stage renal disease (ESRD). It can be indicated to lower phosphate levels in patients with end stage kidney disease. It contains an active ingiednt called Lanthanum Carbonate Hydrate. It is a type of phosphate binder that works by binding to phosphorus in the food you eat, preventing it from being absorbed by your body.

The phosphate in the food binds to Fosrenol and is carried through the digestive tract to be eliminated in your stool. However, elevated levels of phosphate can make it hard for your body to absorb calcium, which can cause serious medical problems.

Uses and Dosage

Fosrenol comes in chewable tablet form, with doses available in 250 mg, 500mg, 750mg, and 1000mg. It is typically taken with meals or snacks, and dosages vary depending on a patient's serum phosphate levels and other factors. To take Fosrenol, chew or crush tablets completely before swallowing. Do not swallow intact tablets, especially if you have poor dentition. Take Fosrenol 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. 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. In clinical studies of patients with end-stage renal disease (ESRD), Fosrenol doses up to 4500 mg were evaluated.
