Patient leaflet - Sevelamer Hydrochloride 800 mg film-coated tablets

1. What Sevelamer Hydrochloride is and what it is used for

Sevelamer Hydrochloride contains sevelamer as the active ingredient. It binds phosphate from food in the digestive tract and so reduces serum phosphate levels in the blood.

Sevelamer Hydrochloride is used to control the levels of phosphate in the blood of adult kidney failure patients on haemodialysis or peritoneal dialysis treatment.

Adult patients whose kidneys have failed and who are undergoing haemodialysis or peritoneal dialysis are not able to control the level of serum phosphate in their blood. The amount of phosphate then rises (your doctor will call this hyperphosphataemia). 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. Increased serum phosphorus can also lead to itchy skin, red eyes, bone pain and fractures.

Sevelamer Hydrochloride may be used with other medicines which include calcium or vitamin D supplements to control the development of renal bone disease.

2. What you need to know before you take Sevelamer Hydrochloride

Do not take Sevelamer Hydrochloride

if you have low levels of phosphate in your blood (your doctor will check this for you). if you have bowel obstruction.

if you are allergic to sevelamer or to any of the other ingredients of this medicine (listed in section 6). Warnings and precautions

Talk to your doctor before taking Sevelamer Hydrochloride if any of the following applies to you:

if you are not on dialysis

if you have swallowing problems

if you have problems with motility (movement) in your stomach and bowel

if you have symptoms of delayed emptying of stomach contents such as feeling of fullness, nausea and/or vomiting

if you have prolonged diarrhoea or pain in the abdomen (symptoms of active inflammatory bowel disease)

if you have undergone major surgery on your stomach or bowel.

Talk to your doctor while taking Sevelamer Hydrochloride:

if you experience severe abdominal pain, stomach or intestine disorders, or blood in the stool (gastrointestinal bleeding). These symptoms can be due to serious inflammatory bowel disease caused by sevelamer crystals deposit in your bowel. Contact your doctor who will decide on continuing the treatment or not.

Additional treatments:

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

develop a low or high level of calcium in your blood. Since Sevelamer Hydrochloride does not contain calcium your doctor might prescribe additional calcium tablets.

have a low amount of vitamin D in your blood. Therefore, 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.

Changing treatment:

When you switch from another phosphate binder to Sevelamer Hydrochloride, your doctor might consider monitoring the levels of bicarbonate in your blood more closely because Sevelamer Hydrochloride may decrease the levels of bicarbonate.

Special note for patients on peritoneal dialysis

You may 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 pain, abdominal tenderness, or abdominal rigidity, constipation, fever, chills, nausea or vomiting. You should expect to be monitored more carefully for problems with low levels of vitamins A, D, E, K and folic acid.

Children and adolescents

The safety and efficacy in children (below the age of 18 years) has not been studied. Therefore Sevelamer Hydrochloride is not recommended for use in this population.

Other medicines and Sevelamer Hydrochloride

Tell your doctor if you are taking, have recently taken or might take any other medicines.

Sevelamer Hydrochloride should not be taken at the same time as ciprofloxacin (an antibiotic). If you are taking medicines for heart rhythm problems or for epilepsy, you should consult your doctor when taking Sevelamer Hydrochloride.

The effects of medicines such as ciclosporin, mycophenolate mofetil and tacrolimus (medicines used in transplant patients) may be reduced by Sevelamer Hydrochloride. Your doctor will advise you if you are taking these medicines.

In certain people taking levothyroxine (a thyroid hormone) and Sevelamer Hydrochloride, increased levels of thyroid stimulating hormone (TSH, a substance in your blood which helps control your body’s chemical functions) may very rarely be observed. Therefore your doctor may monitor the levels of TSH in your blood more closely.

If you are taking medicine such as omeprazole, pantoprazole, or lansoprazole to treat heartburn, gastroesophageal reflux disease (GERD), or gastric ulcers, you should consult your doctor when taking Sevelamer Hydrochloride.

Your doctor will check for interactions between Sevelamer Hydrochloride and other medicines on a regular basis. In some cases where Sevelamer Hydrochloride should be taken at the same time as another medicine, your doctor may advise you to take this medicine 1 hour before or 3 hours after Sevelamer Hydrochloride intake, or he/she may consider monitoring the blood levels of that medicine.

Pregnancy and breast-feeding

The safety of Sevelamer Hydrochloride has not been established in pregnant or breast-feeding women. Sevelamer Hydrochloride should only be given to pregnant or breast-feeding women if clearly needed.

If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your doctor for advice before taking this medicine.

Driving and using machines

Sevelamer Hydrochloride is unlikely to affect your ability to drive or to use machines.

Sevelamer Hydrochloride tablets contain Sorbitol

Sorbitol is a source of fructose. If your doctor has told you that you (or your child) have an intolerance to some sugars or if you have been diagnosed with hereditary fructose intolerance (HFI), a rare genetic disorder in which a person cannot break down fructose, talk to your doctor before you (or your child) take or receive this medicine.

3. How to take Sevelamer Hydrochloride

Always take this medicine exactly as your doctor has told you. Check with your doctor if you are not sure. He will base the dose on your serum phosphate level. The recommended starting dose of Sevelamer Hydrochloride for adults and the elderly (>65 years) is one to two tablets of 800 mg with each meal 3 times a day.
