Ketach powder is a drug belonging to the class of potassium binders, containing the active ingredient Calcium polystyrene sulphonate. It is used to treat hyperkalemia(a condition where there is an excessive amount of potassium in the blood) associated with anuria or severe oliguria. It may also be used to lower potassium levels in people who are undergoing regular dialysis to treat kidney failure. Oral administration of Ketach powder is contraindicated in neonates. This is because neonates have an immature gastrointestinal system and reduced gut motility, which can increase the risk of gastrointestinal complications such as intestinal obstruction and perforation. Magnesium-containing laxatives should not be used along with this powder. Caution is required if you are allergic to this powder or any of its ingredients. Also, it should be avoided if you have an intestinal obstruction, thyroid problems, or high blood calcium levels. Taking too much of this powder may reduce the potassium levels in your blood below the normal level and result in symptoms like muscle weakness, feel so irritable, and confusion. Ketach powder should be used with caution and only under the supervision of a healthcare professional, as it may worsen these conditions or interact with other medications used to treat them.
