1. What is Fosrenol and what is it used for
Fosrenol is used to reduce phosphate levels in the blood in adult patients with chronic kidney disease.
Patient whose kidneys do not function properly cannot control phosphate levels in the blood. As a result, the amount of phosphate in the blood increases (your doctor may refer to this condition as hyperphosphatemia).
Fosrenol is a medication that reduces the absorption of phosphate from food by the body, by binding to it in the digestive tract. The phosphate bound to Fosrenol cannot be absorbed through the intestinal wall.
2. What you need to know before starting to take Fosrenol
Do not take Fosrenol
? if you are allergic to lanthanum carbonate hydrate or any of the other components of this medication (listed in section 6).
? if you have low phosphate levels in the blood (hypophosphatemia).
- if you have intestinal obstruction.
Warnings and precautions
Consult your doctor or pharmacist before starting to take Fosrenol if you know 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)
- 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 well and not swallow them whole or without chewing completely. This will reduce the risk of adverse gastrointestinal complications such as intestinal wall rupture, intestinal obstruction, or constipation (see section 4).
If your kidney function is reduced, your doctor may decide to periodically check your blood calcium levels. If the level is too low, you may be given additional calcium.
If you need to have an X-ray, inform your doctor that you are taking Fosrenol, as it may affect the results.
If you need to have a gastrointestinal endoscopy, inform your doctor that you are taking Fosrenol (lanthanum) because the endoscopist may detect lanthanum accumulation in the digestive tract.
Taking Fosrenol with other medications
Tell your doctor or pharmacist if you are taking, have recently taken, or may need to take any other medication.
Fosrenol may affect how certain medications are absorbed in the digestive tract. If you are taking chloroquine (for rheumatism and malaria), ketoconazole (for fungal infections), or tetracycline or doxycycline antibiotics, you should not take these medications 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 low thyroid activity), you should not take this medication within 2 hours before or after taking Fosrenol. Your doctor may want to monitor your thyroid-stimulating hormone (TSH) levels more closely.
Taking Fosrenol with food and drinks
Fosrenol should be taken with or immediately after food. See section 3 for instructions on taking Fosrenol.
Pregnancy and breastfeeding
Fosrenol should not be used during pregnancy. If you are pregnant or breastfeeding, think you may be pregnant, or plan to become pregnant, consult your doctor or pharmacist before using this medication.
Since it is not known whether the medication can pass into breast milk, you should not continue breastfeeding while taking Fosrenol. If you are breastfeeding, consult your doctor or pharmacist before using any medication.
Driving and using machines
Dizziness and vertigo (a feeling of dizziness or "spinning") are rare adverse reactions that have been reported by patients taking Fosrenol. If you experience these symptoms, they may affect your ability to drive or use machines.

3. How to take Fosrenol
Follow the administration instructions for this medication exactly as indicated by your doctor or pharmacist. If in doubt, consult your doctor or pharmacist again.
You should take Fosrenol with or immediately after food. Adverse effects such as nausea and vomiting are more likely if you take Fosrenol before a meal.
The tablets should be chewed completely and not swallowed whole. To help with chewing, the tablets can be crushed. No additional liquid is needed.
If you have difficulty chewing the tablets, inform your doctor, as this medication is also available in oral powder form.
Your doctor will tell you how many tablets to take with each meal (your daily dose will be divided between meals). The number of tablets you take will depend on the following:
? your diet (the amount of phosphate in the food you eat)
? your blood phosphate level.
Initially, the daily dose of Fosrenol will normally be 1 tablet per meal (3 tablets per day).
Every 2-3 weeks, your doctor will check your blood phosphate levels and may increase the dose until your blood phosphate level is suitable for you.
Fosrenol works by binding to phosphate in your food in your intestine. It is very important to take Fosrenol with each meal. If you change your diet, inform your doctor, as you may need to take additional Fosrenol. Your doctor will advise you on 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. The symptoms of an overdose may be nausea and headache.

If you forget to take Fosrenol
