1. What Fosrenol is and what it is used for
Fosrenol is used to lower high blood phosphate levels in adult patients with chronic kidney disease.
Patients whose kidneys do not work properly cannot control the concentration of phosphate in their blood. As a result, the amount of phosphate in the blood increases (your doctor may refer to this condition as hyperphosphataemia).
Fosrenol is a medicine that reduces the absorption of phosphate from food by the body, by binding to it in the gut. The phosphate bound to Fosrenol cannot be absorbed through the intestinal wall.

Discuss your symptoms and treatment with a doctor online.
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 low levels of phosphate in your blood (hypophosphataemia)
- if you have intestinal obstruction.
Warnings and precautions
Tell your doctor or pharmacist before you start taking Fosrenol if you know that you have or have had any of the following conditions:
- stomach or intestinal cancer
- inflammatory intestinal disease including ulcerative colitis or Crohn's disease
- abdominal surgery or infection or inflammation of the abdomen/intestine (peritonitis)
- stomach or intestinal ulcers
- intestinal obstruction or slow intestinal movement (e.g. constipation and stomach problems due to diabetes)
- reduced liver or kidney function.
If your kidney function is reduced, your doctor may decide to regularly check the level of calcium in your blood. If this level is too low, you may be given extra calcium.
If you are going to have an X-ray, tell your doctor that you are taking Fosrenol, as it may affect the results.
If you are going to have a gastrointestinal endoscopy, tell your doctor that you are taking Fosrenol (lanthanum) because the endoscopist may detect lanthanum accumulation in the gut.
Taking Fosrenol with other medicines
Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines.
Fosrenol may affect how certain medicines are absorbed in the gut. If you are taking chloroquine (for rheumatism and malaria), ketoconazole (for fungal infections) or antibiotics of the tetracycline or doxycycline group, you should not take these medicines within 2 hours before or after taking Fosrenol.
It is not recommended to take oral antibiotics of the fluoroquinolone group (including ciprofloxacin) within 2 hours before or 4 hours after taking Fosrenol.
If you are taking levothyroxine (for underactive thyroid), you should not take this medicine within 2 hours before or after taking Fosrenol. Your doctor may want 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 should not be used 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 medicine can pass to the baby through breast milk, you should not breast-feed while taking Fosrenol. If you are breast-feeding, ask your doctor or pharmacist for advice before taking any medicine.
Driving and using machines
Dizziness and vertigo (a feeling of dizziness or 'spinning') are uncommon side effects that have been reported by patients taking Fosrenol. If you experience these symptoms, they may affect your ability to drive or use machines.
Fosrenol contains glucose
If your doctor has told you that you have an intolerance to some sugars, consult them before taking this medicine.
3. How to take Fosrenol
Follow the instructions for administration of this medicine exactly as told by your doctor or pharmacist. If you are not sure, ask your doctor or pharmacist again.
You should take Fosrenol with or immediately after food. Side effects such as nausea and vomiting are more likely if you take Fosrenol before a meal.
Fosrenol oral powder should be mixed with a small amount of soft food (e.g. apple sauce or similar) and swallowed. You do not need to take extra liquid.
Do not open the sachet until you are ready to take it. Mix the whole contents of the sachet with 1-2 spoonfuls of soft food, making sure that all of the dose is mixed with the food. Make sure you swallow the mixture of oral powder and food immediately (within 15 minutes). Do not save any of the mixture of oral powder and food for later.
Your doctor will tell you how many sachets of oral powder to take with each meal (your daily dose will be divided between meals). The number of sachets you take will depend on:
? your diet (the amount of phosphate in the food you eat)
? your blood phosphate level.
Before starting treatment with Fosrenol oral powder, your doctor may have used Fosrenol chewable tablets to find the right dose for you. Fosrenol chewable tablets come in different strengths, which allows for smaller increases in dose. The starting dose of chewable tablets is usually 250 mg, three times a day with meals. Your dose of oral powder is likely to be 750 or 1000 mg, three times a day with meals. Every 2-3 weeks, your doctor will check the level of phosphate in your blood and may increase your dose until your blood phosphate level is acceptable, and regularly after that.
Fosrenol works by binding to phosphate in your gut. It is very important to take Fosrenol with every meal. If you change your diet, tell 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 much Fosrenol, contact your doctor for an assessment of the risk and advice. Symptoms of overdose may be nausea and headache.
If you have taken more Fosrenol than you should, contact your doctor, pharmacist or call the Toxicology Information Service, telephone: 91-562-04-20, stating the name and amount of the medicine taken.
It is recommended that you take the medicine packaging and leaflet with you to the healthcare professional.
If you forget to take Fosrenol
It is important to take Fosrenol with every meal.
If you forget to take Fosrenol, take the next dose with your next meal. Do not take a double dose to make up for a forgotten dose.
