Lanthanum is used in the management of elevated blood phosphate levels among individuals afflicted with kidney disease. Excessive levels of phosphate in the bloodstream can lead to bone-related complications. Functioning as a member of the phosphate binders class of medications, lanthanum acts by effectively sequestering phosphorus obtained from dietary sources, thereby hindering its absorption into the circulatory system.

Uses and Dosage

Lanthanum is available in two forms: chewable tablets and oral powder, both of which are administered orally. It is usually taken in conjunction with meals, several times a day, as per your doctor’s instructions. To ensure safe and effective usage, carefully adhere to the directions provided on your prescription label, seeking clarification from your doctor or pharmacist for any uncertainties.

Precisely follow your prescribed dosage regimen, refraining from altering the dose—neither increasing nor decreasing it—nor exceeding the recommended frequency of administration.

When consuming the chewable tablets, thoroughly chew them before swallowing, avoid swallowing them whole. If experiencing difficulty chewing, the tablets may be crushed before being chewed.

As for the oral powder, sprinkle it onto a small portion of applesauce or a similar food, and take it immediately with your meal. Refrain from storing any unused mixture after preparation and avoid opening the oral powder container until you are ready to use the medication. Additionally, avoid mixing the lanthanum oral powder with any liquid.

Initially, your doctor is likely to start you on a low dose of lanthanum and gradually increase it, with adjustments made no more frequently than once every 2 to 3 weeks.

Does Fosrenol contain calcium?

Fosrenol does not contain calcium or aluminum. Fosrenol is a phosphate binder that reduces absorption of phosphate by forming insoluble lanthanum phosphate complexes that pass through the gastrointestinal tract unabsorbed.

Why do I have to take Fosrenol with food?

Fosrenol works by binding to the phosphorus in your food. The medication won’t work if you take it on an empty stomach because there’s no food to bind to.
