1. What Fosrenol is and what it is used for

Fosrenol is used to reduce blood phosphorus levels in adult patients with chronic kidney disease.

Patients whose kidneys do not function properly are unable to control the level of phosphorus in the blood. As a result, the amount of phosphorus in the blood increases (your doctor may refer to this condition as hyperphosphatemia).

Fosrenol is a medicine that reduces the absorption of dietary phosphorus by the body by binding to it in the gastrointestinal tract. Phosphorus bound to Fosrenol cannot be absorbed through the intestinal wall.

2. What you need to know before taking Fosrenol

Do not take Fosrenol

• if you are allergic to lanthanum carbonate hydrate or to any of the other ingredients of this medicine (listed in section 6)

• if you have low levels of phosphate in the blood (hypophosphataemia)

• if you have intestinal obstruction.

Warnings and precautions

Talk to your doctor or pharmacist before taking Fosrenol if you know you have or have had any of the following conditions:

• stomach or intestinal cancer
• inflammatory bowel disease including ulcerative colitis or Crohn's disease
• abdominal surgery or infection or inflammation of the abdomen/intestine (peritonitis)
• gastric or intestinal ulcers
• intestinal obstruction or slow intestinal transit (e.g., constipation and stomach complications due to diabetes)
• reduced liver or kidney function.

It is very important to chew Fosrenol tablets thoroughly and not to swallow them whole or incompletely chewed. This will reduce the risk of gastrointestinal adverse complications such as perforation of the intestinal wall, intestinal obstruction, or constipation (see section 4).

If your kidney function is reduced, your doctor may decide to monitor your blood calcium levels periodically. If these levels are too low, you may be given additional calcium.

If you are due to have an X-ray, inform your doctor that you are taking Fosrenol, as it may affect the results.

If you are due to have a gastrointestinal endoscopy, inform your doctor that you are taking Fosrenol (lanthanum), as the endoscopist may detect lanthanum accumulation in the gastrointestinal tract.

Taking Fosrenol with other medicines

Tell your doctor or pharmacist if you are taking, have recently taken, or might need to take any other medicines.

Fosrenol may affect how certain medicines are absorbed in the gastrointestinal tract. If you are taking chloroquine (for rheumatism and malaria), ketoconazole (for fungal infections), or tetracycline or doxycycline antibiotics, you must not take these drugs within 2 hours before or after taking Fosrenol.

It is not recommended to take oral fluoroquinolone antibiotics (including ciprofloxacin) within 2 hours before or 4 hours after taking Fosrenol.

If you are taking levothyroxine (for underactive thyroid), you must not take this medicine within 2 hours before or after taking Fosrenol. Your doctor may wish to monitor your thyroid-stimulating hormone (TSH) blood levels more closely.

Taking Fosrenol with food and drink

Fosrenol should be taken with or immediately after food. See section 3 for instructions on how to take Fosrenol.

Pregnancy and breast-feeding

Fosrenol must not be used during pregnancy. If you are pregnant or breast-feeding, think you may be pregnant, or are planning to become pregnant, consult your doctor or pharmacist before using this medicine.

Since it is unknown whether the medicine passes into breast milk, you must not continue breastfeeding while taking Fosrenol. If you are breast-feeding, consult your doctor or pharmacist before using any medicine.

Driving and using machines

Dizziness and vertigo (a sensation of spinning or dizziness) are uncommon side effects reported by patients taking Fosrenol. If you experience these symptoms, they may affect your ability to drive or operate machinery.

Fosrenol contains glucose

If your doctor has informed you that you have an intolerance to certain sugars, consult with him before taking this medicine.

3. How to take Fosrenol

Follow exactly the instructions for using this medicine as given by your doctor or pharmacist. If in doubt, consult your doctor or pharmacist again.

You should take Fosrenol with food or immediately after eating. Adverse effects such as nausea and vomiting are more likely if you take Fosrenol before meals.

The tablets must be completely chewed and must not be swallowed whole. To aid chewing, the tablets may be crushed. It is not necessary to take additional liquid.

If you have difficulty chewing the tablets, inform your doctor, as this medicine is available as an oral powder.

Your doctor will tell you how many tablets to take with each meal (your daily dose will be divided among your meals). The number of tablets you take will depend on the following:

• your diet (the amount of phosphorus in the foods you eat)
• your blood phosphorus level.

Initially, the daily dose of Fosrenol will usually be 1 tablet per meal (3 tablets per day).

Every 2–3 weeks your doctor will check your blood phosphorus levels and may increase your dose until your blood phosphorus level is appropriate for you.

Fosrenol works by binding to phosphorus from food in your intestine. It is very important to take Fosrenol with every meal. If you change your diet, inform your doctor, as you may need additional Fosrenol. Your doctor will advise you what to do in this case.

If you take more Fosrenol than you should

If you take too many tablets, contact your doctor to assess the risk and receive advice. Symptoms of overdose may include nausea and headache.

If you have taken more Fosrenol than you should, contact your doctor, pharmacist, or call the Toxicology Information Service immediately at: 91-562-0420, indicating the medicine and the amount taken.

If you forget to take Fosrenol

It is important that you take Fosrenol with every meal.

If you forget to take your Fosrenol tablets, take the next dose with your next meal. Do not take a double dose to make up for forgotten doses.

If you have any further questions about the use of this medicine, ask your doctor or pharmacist.
