1. What is Fosrenol and what is it used for
Fosrenol is used to reduce the level of phosphorus in the blood of adult patients with chronic kidney disease.
Patients whose kidneys do not function properly cannot control the concentration 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 phosphorus from food by the body, by binding to it in the digestive tract. The 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 any of the other ingredients of this medicine (listed in section 6)
? if you have a low level of phosphorus in the blood (hypophosphatemia)
- if you have intestinal obstruction.
Warnings and precautions
Talk to 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.
If your kidney function is reduced, your doctor may decide to periodically check the level of calcium in your blood. If this level is too low, you may be given additional calcium.
If you are going to have an X-ray, inform your doctor that you are taking Fosrenol, as it may affect the results.
If you are going 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 medicines
Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines.
Fosrenol may affect the way certain medicines are absorbed in the digestive tract. If you are taking chloroquine (for rheumatism and malaria), ketoconazole (for fungal infections) or antibiotics of the tetracycline or doxycycline group, do 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 low thyroid activity), do not take this medicine 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 how to take Fosrenol.
Pregnancy and breastfeeding
Fosrenol should not be used during pregnancy. If you are pregnant or breastfeeding, think you may be pregnant or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine.
Since it is not known whether the medicine can pass into breast milk, you should not breastfeed while taking Fosrenol. If you are breastfeeding, 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 certain sugars, consult them before taking this medicine.
3. How to take Fosrenol
Follow the instructions for administration of this medicine exactly as prescribed by your doctor or pharmacist. If you are unsure, consult 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 soft food (e.g. apple sauce or similar food) and swallowed immediately. No additional liquid is needed.
Do not open the sachet until the time of use. Mix the entire contents of the sachet with 1-2 tablespoons of soft food, making sure that the entire dose is mixed with the food. Make sure to swallow the mixture of oral powder and food immediately (within the next 15 minutes). Do not save any of the mixture of oral powder and food for later use.
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 phosphorus level.
Before starting Fosrenol oral powder, your doctor may have used Fosrenol chewable tablets to find the right dose. Fosrenol chewable tablets come in different strengths, allowing for smaller dose increases. The initial dose of chewable tablets is usually 250 mg, three times a day with meals. Your oral powder dose is likely to be 750 or 1000 mg, three times a day with meals. Every 2-3 weeks, your doctor will check your blood phosphorus level and may increase the dose until your blood phosphorus level is acceptable, and regularly after that.
Fosrenol works by binding to phosphorus in your food in your intestine. It is very important to take Fosrenol with each 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 to assess the risk and receive advice. Symptoms of an 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, phone: 91-562-04-20, stating the medicine and the amount taken.
It is recommended to take the medicine packaging and package leaflet to the healthcare professional.
If you forget to take Fosrenol
It is important to take Fosrenol with each meal.
If you forget to take Fosrenol, take the next dose with the next meal. Do not take a double dose to make up for forgotten doses.
