1. What Fosrenol is and what it is used for
Fosrenol is used to lower the phosphate level in the blood of adult patients with chronic kidney disease.
Patients who have kidneys that do not work properly are not able to control the level of phosphate in the blood. The amount of phosphate in the blood then rises (your doctor may call this hyperphosphataemia).
Fosrenol is a drug which reduces the body's absorption of phosphate from food by binding with it in your digestive tract. Phosphate which have bonded to Fosrenol cannot be absorbed through the intestinal wall.
2. What you need to know before you take Fosrenol
Do not take Fosrenol
-
if you are allergic to lanthanum carbonate hydrate or any of the other ingredients of this medicine (listed in section 6).
-
if you have too little phosphate in your blood (hypophosphataemia)
Warnings and precautions
Talk to your doctor or pharmacist before taking Fosrenol if you know that you have, or have had, any of the following:
-
stomach or intestinal cancer
-
inflammatory bowel disease including ulcerative colitis or Crohn’s disease
-
abdominal surgery, or infection or inflammation of the abdomen/bowel (peritonitis)
-
stomach or intestinal ulcers
-
blockage of the intestine or slow motility (movement) in the intestine (e.g. constipation and stomach complications due to diabetes)
-
reduced liver or kidney function.
If you have reduced kidney function your doctor may decide to check the level of calcium in your blood from time to time. If you have too little calcium, you may then be given extra calcium.
If you need to have an x-ray, please inform your doctor that you are taking Fosrenol as it may affect the results.
Other medicines and Fosrenol
Tell your doctor or pharmacist if you are taking, have recently taken, or might take any other medicines.
Fosrenol can affect how certain drugs are absorbed from your digestive tract. If you are taking chloroquine (for rheumatism and malaria), ketoconazole (for fungal infections), tetracycline or doxycycline antibiotics they should not be taken within 2 hours before or after taking Fosrenol.
It is not recommended that you take oral floxacin antibiotics (including ciprofloxacin) within 2 hours before or 4 hours after taking Fosrenol.
If you are taking levothyroxine (for an under active thyroid) it should not be taken within 2 hours before or after taking Fosrenol. Your doctor may want to monitor the levels of thyroid-stimulating hormone (TSH) in your blood more closely.
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 should not be taken during pregnancy. If you are pregnant or breast-feeding, think you may be pregnant, or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine.
As it is not known whether the drug can be transferred to a child in breast-milk, you should not breast-feed whilst taking Fosrenol. If you are breast-feeding, ask your doctor or pharmacist for advice before taking any medicines.

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

3. How to take Fosrenol
Always take this medicine exactly as your doctor or pharmacist has told you. Check with your doctor or pharmacist if you are not sure.
You should take Fosrenol with, or immediately after food. Side effects such as nausea and vomiting are more likely if you take Fosrenol before your meal.
The tablets must be chewed completely and not swallowed whole. To aid with chewing, the tablets may be crushed. Additional fluid is not necessary. If you find chewing the tablets difficult, talk to your doctor as an oral powder form of this medicine is available.
Your doctor will tell you how many tablets you must take with each meal (your daily dose will be divided between meals). The number of tablets that you take will depend on:
-
Your diet (the amount of phosphate in the food you eat)
-
Your blood phosphate level
To start with, the daily dose of Fosrenol will usually be 1 tablet with each meal (3 tablets per day).
Every 2-3 weeks your doctor will check the level of phosphate in your blood and may increase your dose until the level of phosphate in your blood is acceptable.
Fosrenol works by binding phosphate from the food in your gut. It is very important to take Fosrenol at every meal. If you change your diet, contact your doctor as you may need to take extra Fosrenol. Your doctor will tell 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 obtain advice. Symptoms of overdose may be nausea and headaches.
If you forget to take Fosrenol
It is important to take Fosrenol with every meal.
If you forget to take your Fosrenol tablets, then take the next dose with your next meal. Do not take a double dose to make up for a forgotten dose.
