Fosrenol Description

Fosrenol is a phosphate binder drug that may be prescribed to patients undergoing dialysis for end stage renal disease (ESRD) as a way to prevent the increase of phosphorus levels gained from the foods they eat. This occurs due to the kidney’s inability to maintain proper phosphorous levels by removing any excess amounts which can lead to hyperphosphatemia. The goal is to treat this condition early in the course of kidney failure to avoid changes in your bones, joints, and cardiovascular tissues that high levels of phosphorus can cause.

How Fosrenol Works to Reduce Phosphorus Levels in Your Body

Many of the foods you eat contain phosphorus so it’s important to take Fosrenol with or immediately after a meal or snack. When taken as directed, Fosrenol or generic Lanthanum works similar to a magnet. Phosphorus from the diet is drawn to Fosrenol where it binds in the upper gastrointestinal tract and is carried through the digestive tract and out of the body. This helps to slow down the effects of a high phosphate level which can cause the body to pull calcium from your bones in an effort to maintain a proper balance of minerals in the body. The generic alternative is not manufactured by the company that makes the brand product.

How Important is Phosphorus?

Phosphorus is the second most common mineral in your body after calcium. Your bones and teeth store approximately 85% of your total phosphorus. This essential mineral is responsible for creating energy, forming strong bones and teeth, producing hormones, using B vitamins, and maintaining a normal pH balance, among other functions.

As the health of your kidneys declines due to end stage renal disease, the build- up of phosphorus in your blood alerts your body that calcium has to catch up because levels of these minerals are now unbalanced. As calcium is pulled from your bones, you are now left vulnerable to an increased risk of losing your structural support as bones are weakened. As Fosrenol lowers phosphorus levels, less calcium is pulled from your bones so you are less at risk for breakage.

Before You Take Fosrenol

Tell your doctor if you are pregnant, may become pregnant, or are breast feeding before taking Fosrenol as it may be harmful to your unborn or nursing baby. Explain other medical conditions and allergies you have to your doctor and list all non-prescription medications and Rx drugs you are taking, including herbal potions and vitamin supplements. Certain medicine may be altered or become more difficult to be absorbed when taken at the same time as Fosrenol. If you are scheduled for stomach x-rays, inform the doctor or technician that you are taking Fosrenol as it can interfere with the results.

Important Information About Fosrenol

Fosrenol tablets must be chewed or crushed before swallowing; do not swallow whole! If you are taking antacids, they should be taken two hours before or after taking Fosrenol as they can make it more difficult for your body to absorb phosphorus binders. Follow the nutritionist’s low phosphorus diet to make Fosrenol more effective. Do not stop taking Fosrenol without your doctor’s knowledge.
