What is in this leaflet

This leaflet answers some common questions about this medicine. It does not contain all the available information. It does not take the place of talking to your doctor or pharmacist.

All medicines have risks and benefits. Your doctor has weighed the risks of you taking this medicine against the benefits they expect it will have for you.

If you have any concerns about taking this medicine, ask your doctor or pharmacist.

Keep this leaflet with the medicine. You may need to read it again.

What this medicine is used for

Sevelamer is used to treat hyperphosphatemia, a condition caused by too much dietary phosphorus being retained in your body due to a diseased kidney.

Increased levels of serum phosphorus can lead to hard deposits in your body called calcification. These deposits can stiffen your blood vessels and make it harder for blood to be pumped around the body.

Sevelamer helps to remove excess phosphorus that has built up in your body by binding to the phosphorus that is in the food that you eat.

Ask your doctor if you have any questions about why this medicine has been prescribed for you. Your doctor may have prescribed it for another reason.

This medicine is available only with a doctor’s prescription.

Some medicines and this one may interfere with each other. These include:

  • medications for thyroid, such as levothyroxine – your doctor may need to monitor the levels of thyroid stimulating hormone (TSH) in your blood more closely
  • medications for heart rhythm problems
  • medications for epilepsy

These medicines may be affected by sevelamer or may affect how well it works. You may need different amounts of your medicines, or you may need to take different medicines.

Your doctor and pharmacist have more information on medicines to be careful with or avoid while taking this medicine.

How to take this medicine

Follow all directions given to you by your doctor or pharmacist carefully. They may differ from the information contained in this leaflet.

If you do not understand the directions, ask your doctor or pharmacist for help.

How much to take

The recommended starting dose of sevelamer is 2.4 g to 4.8 g per day to be taken over 3 meals.

For tablets, this means one to two 800 mg tablets with each meal three times a day.

The dose will depend on your serum phosphorus level.

How to take it

Swallow the tablets whole with a full glass of water.

Do not crush, chew or break into pieces.

When to take it

Take your medicine at about the same time each day. Taking it at the same time each day will have the best effect. It will also help you remember when to take it.

It is best to take sevelamer with meals.

How long to take it

Continue taking your medicine for as long as your doctor tells you.

Sevelamer helps lower your dietary phosphate but does not cure your condition. Therefore, you must continue to take your medicine as directed by your doctor if you expect to lower your phosphate level and keep it down.

If you stop taking sevelamer, your phosphate levels may rise again. It is important to keep taking your medicines even if you feel well.

If you forget to take it

If you miss a dose, take the next dose at the usual time with your meal.

Do not take a double dose to make up for the dose that you missed. This may increase the chance of you getting an unwanted side effect.

If you are not sure what to do, ask your doctor or pharmacist.

If you have trouble remembering to take your medicine, ask your pharmacist for some hints.

If you take too much (overdose)

Immediately telephone your doctor or the Poisons Information Centre (telephone 13 11 26) for advice or go to Accident and Emergency at the nearest hospital, if you think that you or anyone else may have taken too much of this medicine. Do this even if there are no signs of discomfort or poisoning.

You may need urgent medical attention.

While you are using this medicine

Things you must do

If you are about to be started on any new medicine, remind your doctor and pharmacist that you are taking this medicine.

Tell any other doctors, dentists, and pharmacists who treat you that you are taking this medicine.

If you are going to have surgery, tell the surgeon or anaesthetist that you are taking this medicine. It may affect other medicines used during surgery.

If you become pregnant or start to breastfeed while taking this medicine, tell your doctor immediately.

If you are about to have any blood tests, tell your doctor that you are taking this medicine. It may interfere with the results of some tests.

Keep all your doctor’s appointments so that your progress can be checked. Your doctor will check your progress and monitor your phosphorus levels from time to time to make sure the medicine is working and to prevent unwanted side effects.

Things you must not do

Do not take this medicine to treat any other complaints unless your doctor tells you to.

Do not give your medicine to anyone else, even if they have the same condition as you.

Do not stop taking your medicine or lower the dosage without checking with your doctor. Your doctor may need to change the dose of your other medicines if you stop taking sevelamer, so you should only stop when your treating doctor tells you to.

Things to be careful of

Due to either your kidney condition or your dialysis treatment you may:

  • develop low or high levels of calcium in your blood – since this medicine does not contain calcium your doctor may prescribe additional calcium tablets
  • have a low amount of vitamin D in your blood – your doctor may monitor the levels of vitamin D in your blood and prescribe additional vitamin D as necessary. If you do not take multivitamin supplements you may also develop low levels of vitamins A, E, K and folic acid in your blood and therefore your doctor may monitor these levels and prescribe supplemental vitamins as necessary
  • develop peritonitis (infection of your abdominal fluid) associated with your peritoneal dialysis – this risk can be reduced by careful adherence to sterile techniques during bag changes. You should tell your doctor immediately if you experience any new signs or symptoms of abdominal distress, abdominal swelling, abdominal tenderness, constipation, fever, chills, nausea or vomiting.
