Warnings and precautions

Consult your doctor or pharmacist before starting to take Fosrenol if you know that 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, infection, or inflammation (peritonitis)
• gastric or intestinal ulcers
• intestinal obstruction or slow intestinal transit (e.g., constipation and gastrointestinal 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 them completely. This will reduce the risk of adverse gastrointestinal complications such as intestinal perforation, 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 this level is too low, you may be given additional calcium.

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

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

Taking Fosrenol with other medicines

Inform your doctor or pharmacist if you are taking, have taken recently, or may need to take any other medicine.

Fosrenol may affect how certain medicines are absorbed in the digestive tract. If you are taking chloroquine (for rheumatism and malaria), ketoconazole (for fungal infections), or tetracycline or doxycycline antibiotics, do not take those medicines 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), do not take that medicine within 2 hours before or after taking Fosrenol. Your doctor may want to monitor your blood levels of thyroid-stimulating hormone (TSH) more closely.

Taking Fosrenol with food and drinks

Fosrenol should be taken with food or immediately after eating 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, or think you may be pregnant, consult your doctor or pharmacist before using this medicine.

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 will take will depend on the following:

?your diet (the amount of phosphorus in the foods you consume)

?your blood phosphorus level.

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

Every 2-3 weeks, your doctor will checkyour blood phosphorus concentrations and may increase the dose until your blood phosphorus level is suitable for you.

Fosrenol acts by binding to phosphorus in your food in your intestine. It is very important to take Fosrenol with each meal. If you modify your diet, inform your doctor, as you may need to take additional Fosrenol. Your doctor will advise you on what to do in such cases.
