Drug pricing is set separately in each country through different negotiation, regulatory, and distribution systems, so the same medication can legitimately carry different price tags on either side of the border. In this case, our data shows the Canadian price coming in lower — but that isn't true for every drug, so it's worth checking each medication individually rather than assuming.

Sodium Polystyrene Sulfonate is the generic name for the medication. It is manufactured by companies such as KVK-Tech, Inc. and Perrigo Company. The two primary brand-name products containing this drug are Kionex and Kalexate.

Sodium Polystyrene Sulfonate is a prescription drug that treats hyperkalemia by binding to excess potassium in the digestive tract, allowing it to be eliminated from the body. It is administered as an oral powder, typically taken one to four times daily as directed by a physician. Dosing is individualized based on your medical condition, other medications, and treatment response. It is crucial to measure each dose with the provided device, not a household spoon, and to remain upright for at least an hour after taking it. Because this medication can interfere with the absorption of other drugs, your doctor may advise spacing doses at least three hours apart from your other medications. Always take exactly as prescribed and do not exceed the recommended duration of use.

Common side effects include gastrointestinal issues like nausea, vomiting, constipation, diarrhea, or decreased appetite. If these effects persist or become bothersome, consult your doctor or pharmacist. Serious side effects are less common but require immediate medical attention. These include signs of intestinal complications such as severe constipation, abdominal bloating or swelling, black or bloody stools, or vomit resembling coffee grounds. Although rare, severe allergic reactions can occur. Seek emergency help if you experience symptoms like rash, itching, swelling of the face or throat, severe dizziness, chest tightness, or trouble breathing. This is not an exhaustive list; discuss all potential risks and benefits with your healthcare provider.
