Sodium Polystyrene Sulfonate: Brands, Price & Uses in Bangladesh
Sodium Polystyrene Sulfonate is a potassium-binding (cation-exchange) resin used for the treatment of hyperkalemia (elevated blood potassium).
About Sodium Polystyrene Sulfonate
Indications of Sodium Polystyrene Sulfonate
Sodium Polystyrene Sulfonate is a potassium-binding (cation-exchange) resin used for the treatment of hyperkalemia (elevated blood potassium).
Established / FDA-approved use
- Treatment of hyperkalemia in patients who need to lower elevated serum potassium levels, most commonly in chronic kidney disease, when dietary/medication changes alone are insufficient.
Guideline-supported / adjunct use
- Used as an adjunct to standard emergency measures (e.g., calcium gluconate, insulin/glucose, dialysis) in acute, severe hyperkalemia — Sodium Polystyrene Sulfonate alone is not appropriate as sole therapy for a life-threatening potassium elevation because its onset of action is not immediate.
- Used for short-term or intermittent management of chronic/recurrent hyperkalemia, such as in patients on renin-angiotensin system inhibitors or with end-stage renal disease between dialysis sessions.
It does not treat the underlying cause of hyperkalemia and is not intended for routine long-term use given its gastrointestinal and sodium-load risks.
Dosage & Administration of Sodium Polystyrene Sulfonate
Dosing of Sodium Polystyrene Sulfonate is individualized based on the degree of hyperkalemia and the patient's response, with frequent monitoring of serum potassium.
| Indication / Population | Route | Typical Dose |
|---|---|---|
| Adult hyperkalemia | Oral | 15 g suspended in water or a compatible vehicle, given 1 to 4 times daily (total range approximately 15–60 g/day), adjusted to potassium response |
| Adult hyperkalemia (when oral not feasible/tolerated) | Rectal (retention enema) | 30–50 g as a warm suspension, retained as long as possible, repeated approximately every 6 hours as needed |
| Pediatric hyperkalemia | Oral (with caution) / Rectal | Lower, weight-based doses calculated on an approximate 1 mEq potassium removed per gram of resin basis; individualized by a physician. Oral use is contraindicated in neonates. |
See Dosage and Administration sections below, and Precautions and Warnings, for important safety limits on duration and monitoring.
Side Effects of Sodium Polystyrene Sulfonate
The following side effects have been reported with Sodium Polystyrene Sulfonate.
Common
- Nausea, vomiting, anorexia, gastric irritation
- Constipation or, less often, diarrhea
Electrolyte-related
- Hypokalemia (from overcorrection), hypocalcemia, hypomagnesemia, and sodium retention (see Precautions and Warnings for monitoring guidance).
Serious (uncommon but important)
- Intestinal necrosis, fecal impaction, gastrointestinal concretions/bezoars, ischemic colitis, and bowel perforation — see Precautions and Warnings.
Contraindications of Sodium Polystyrene Sulfonate
- Known hypersensitivity to Sodium Polystyrene Sulfonate or any component of the formulation.
- Abnormal bowel function, including bowel obstruction, ileus (including postoperative ileus), or other conditions that impair intestinal transit.
- Neonates, particularly premature infants, for oral use — this population is at heightened risk of intestinal necrosis, especially with sorbitol-containing formulations.
- Hypokalemia (low baseline potassium).
Frequently Asked Questions about Sodium Polystyrene Sulfonate
What is Sodium Polystyrene Sulfonate used for?
Sodium Polystyrene Sulfonate is used to treat hyperkalemia (high blood potassium), most often in people with kidney disease. It works by binding excess potassium in the gut so it can be removed from the body in the stool. It is not meant to treat a severe, life-threatening potassium emergency on its own.
How is Sodium Polystyrene Sulfonate taken?
Sodium Polystyrene Sulfonate is usually given as a powder mixed with water (never sorbitol) and taken by mouth, once to four times a day as directed by your physician. In some cases it may be given as a retention enema instead. Always follow your doctor's specific instructions on dose and timing.
Can Sodium Polystyrene Sulfonate be used in children or newborns?
Sodium Polystyrene Sulfonate has not been formally proven safe and effective in children, and it must never be given by mouth to newborn babies (neonates), especially premature infants, because of a serious risk of intestinal necrosis (tissue damage in the bowel). Any pediatric use should be individualized and closely supervised by a physician.
What are the main risks or side effects of Sodium Polystyrene Sulfonate?
The most serious risk with Sodium Polystyrene Sulfonate is intestinal necrosis (a rare but potentially fatal bowel injury), which is more likely if it is combined with sorbitol or given to someone with sluggish bowel movements. More common side effects include nausea, loss of appetite, constipation or diarrhea, and changes in blood potassium, calcium, magnesium, and sodium levels, which your doctor will monitor with blood tests.
Is Sodium Polystyrene Sulfonate safe during pregnancy or breastfeeding?
Information on Sodium Polystyrene Sulfonate in pregnancy is limited, so it should be used in pregnancy only if your physician decides the benefit clearly outweighs the potential risk to the baby. It is not known whether it passes into breast milk in a meaningful amount, so breastfeeding mothers should consult their physician before use.
What should I do if I take too much Sodium Polystyrene Sulfonate?
Taking more Sodium Polystyrene Sulfonate than prescribed can cause a sudden drop in blood potassium along with low calcium and magnesium, which may cause muscle weakness, confusion, or irregular heartbeat. If you suspect an overdose, seek immediate medical attention or contact emergency services or a poison control center right away rather than trying to manage it at home.
