1. What Sorbisterit is and what Sorbisterit is used for?
Sorbisterit is used in the treatment of hyperkalaemia (raised blood potassium content), in patients who have kidney problems and those on dialysis (removal of waste products from the blood). Sorbisterit is a cation exchange resin (insoluble structure which releases certain ions in exchange for other ions) that exchanges potassium for calcium in the gut. As a result, it reduces the uptake of potassium into the blood.
2. Before you use Sorbisterit
Do not use Sorbisterit if your blood contains too little potassium, manifested in a severe form by muscle cramps or muscle weakness and fatigue if your blood contains too much calcium if you are allergic (hypersensitive) to calcium polystyrene sulphonate or any of the other ingredients of Sorbisterit if you suffer from constipation or complete blockage of the bowel concomitant administration of sorbitol (a laxative) in newborn babies by the oral route in newborn babies with constipation

3. How to use Sorbisterit
Always use Sorbisterit exactly as your doctor has told you. You should check with your doctor or pharmacist if you are not sure. The necessary duration of treatment is dependent on the daily measurements of the potassium level in the blood. The usual dose is: Oral use Adults and the elderly: 1 measuring spoonful (20 g powder) 1 - 3 times daily, stirred into approximately 150 ml of liquid. Children: 0.5 - 1 g powder per kilogram of body weight, stirred into approximately 150 ml of liquid.
This preparation is taken in at least three divided doses over a period of 24 hours. Suitable liquids are water, tea or soft drinks. Sorbisterit must be taken with the main meals with the upper body in an upright position. Rectal use Adults and the elderly: After using an enema, 2 measuring spoonfuls of Sorbisterit (40 g) are dispersed in 150 ml of 5% glucose solution and administered via the anus 1 - 3 times daily. Retention time: 6 hours. Children: Administration via the anus takes place if Sorbisterit cannot be swallowed. The dosage is the same as for oral use.
Dilution takes place in exactly the same way as already described for use in adults. Six hours after introduction into the anus, the colon should be irrigated to remove the resin. Special care is necessary when used in children and newborn babies, as too high a dosage or incorrect dilution may cause the resin to have too strong an effect. Particular caution is necessary in subjects with a low body weight especially neonates on account of gastrointestinal haemorrhages and the risk of death (necrosis) of the colon. If you feel that the effect of Sorbisterit is too strong or too weak, ask your doctor or pharmacist for advice.
If you use more Sorbisterit than you should If you have used too much Sorbisterit, tell your doctor or pharmacist immediately. In general, an overdose of Sorbisterit may lead to a reduced level of potassium in the blood (hypokalaemia) with symptoms of cramps, discomfort in the legs that is experienced while sitting still, extreme weakness of the body, and on occasion, paralysis. Abnormal heart beat may occur. Other side effects of overdose may take the form of a raised calcium level in the blood (hypercalcaemia) with symptoms such as fatique, muscle weakness, frequent urination, constipation, abnormal heart beat, kidney failure or coma. Further, an overdose may lead to constipation, complete bowel blockage and fluid accumulation.
If you forget to use Sorbisterit Ask your doctor or pharmacist for advice. Do not take a double dose of Sorbisterit to make up for a forgotten dose. If you stop taking Sorbisterit This may lead to an increase in the potassium content of the blood.
