Contents of the pack and other information
Sevelamer carbonate Winthrop contains the active substance sevelamer carbonate. It binds phosphate from food in the digestive tract and so reduces serum phosphorus levels in the blood.
This medicine is used to control hyperphosphataemia (high blood phosphate levels) in:
adult patients on dialysis (a blood clearance technique). It can be used in patients undergoing haemodialysis (using a blood filtration machine) or peritoneal dialysis (where fluid is pumped into the
abdomen and an internal body membrane filters the blood);
patients with chronic (long-term) kidney disease who are not on dialysis and have a serum (blood) phosphorus level equal to or above 1.78 mmol/L.
This medicine should be used with other treatments such as calcium supplements and vitamin D to prevent the development of bone disease.
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.
if you are allergic to sevelamer carbonate or any of the other ingredients of this medicine (listed in section 6).
if you have low levels of phosphate in your blood (your doctor will check this for you).
if you have bowel obstruction.
Talk to your doctor before taking Sevelamer carbonate Winthrop:
if you have swallowing problems. Your doctor can rather prescribe sevelamer carbonate powder for oral suspension.
if you have problems with motility (movement) in your stomach and bowel
if you have active inflammation of the bowel
if you have undergone major surgery on your stomach or bowel.
Talk to your doctor while taking Sevelamer carbonate Winthrop:
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 crystal 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 low or high levels of calcium in your blood. Since this medicine 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.
have disturbed level of bicarbonate in your blood and increased acidity in the blood and other body tissue. Your doctor should monitor the level of bicarbonate in your blood.
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.
Do not give this medicine to children below the age of 6 years because the safety and efficacy in children (below the age of 6 years) have not been studied.
Tell your doctor if you are taking, have recently taken or might take any other medicines.
Sevelamer carbonate Winthrop 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 carbonate Winthrop.
The effects of medicines such as ciclosporin, mycophenolate mofetil and tacrolimus (medicines used to suppress the immune system) may be reduced by Sevelamer carbonate Winthrop. Your doctor will advise you if you are taking these medicines.
Thyroid hormone deficiency may uncommonly be observed in certain people taking levothyroxine (used to treat low thyroid hormone levels) and Sevelamer carbonate Winthrop. Therefore your doctor may monitor the levels of thyroid stimulating hormone in your blood more closely.
Medicines treating heartburn and reflux from your stomach or oesophagus, such as omeprazole, pantoprazole, or lansoprazole, known as “proton pump inhibitors”, may reduce the efficacy of Sevelamer carbonate Winthrop. Your doctor may monitor the phosphate level in your blood.
Your doctor will check for interactions between Sevelamer carbonate Winthrop and other medicines on a regular basis.
In some cases where Sevelamer carbonate Winthrop 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 carbonate Winthrop intake. Your doctor may also consider monitoring the levels of that medicine in your blood.
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.
The potential risk of Sevelamer carbonate Winthrop during human pregnancy is unknown. Talk to your
doctor who will decide if you can continue the treatment with Sevelamer carbonate Winthrop.
It is unknown whether Sevelamer carbonate Winthrop is excreted in breast milk and may affect your baby. Talk to your doctor who will decide if you can breastfeed your baby or not, and if it is necessary to stop Sevelamer carbonate Winthrop treatment.
Sevelamer carbonate Winthrop is unlikely to affect your ability to drive or to use machines.
This medicine contains less than 1 mmol sodium (23 mg) per tablet that is to say essentially ‘sodium-free’.
Always take this medicine exactly as your doctor has told you. He will base the dose on your serum phosphorus level.
The recommended starting dose of this medicine for adults and elderly is one to two tablets of 800 mg with each meal, 3 times a day. Check with your doctor, pharmacist or nurse if you are not sure.
Take Sevelamer carbonate Winthrop after your meal or with food.
The tablets must be swallowed whole. Do not crush, chew or break into pieces.
Initially, your doctor will check the levels of phosphorus in your blood every 2-4 weeks and may adjust the dose of Sevelamer carbonate Winthrop when necessary to reach an adequate phosphate level.
Follow the diet prescribed by your doctor.
In the event of a possible overdose you should contact your doctor immediately.
If you have missed one dose, this dose should be omitted and the next dose should be taken at the usual time with a meal. Do not take a double dose to make up for a forgotten dose.
Taking your Sevelamer carbonate Winthrop treatment is important to maintain an appropriate phosphate level in your blood. Stopping Sevelamer carbonate Winthrop would lead to important consequences such as
calcification in the blood vessels. If you consider stopping your Sevelamer carbonate Winthrop treatment, contact your doctor or pharmacist first.
If you have any further questions on the use of this medicine, ask your doctor or pharmacist.
