Oral electrolyte salts
Prescription status is set country by country — the label where you live is the one that applies.

Oral electrolyte salts are mixtures of the minerals lost in sweat and in other fluid losses, chiefly sodium, potassium, chloride and magnesium, usually together with a small amount of glucose. The glucose is not there for taste: sodium and water are absorbed alongside it through the gut wall, which is what makes a salt-and-sugar solution rehydrate faster than plain water. They are used for hydration around heavy sweating, hot weather, or fluid loss through illness.
A usual adult range, not a national label — the dose and the timing differ by country and by product.
Approved uses differ by country — some of these may be off-label or unapproved where you live.
The salts need enough water to work with; taken too concentrated they draw fluid into the gut and loosen the stool. Potassium is the part that needs attention, because spironolactone and the ACE inhibitors lisinopril, enalapril and ramipril all hold potassium back in the body, and adding more on top is how levels climb into a dangerous range. Excess potassium leaves through the kidneys, so reduced kidney function removes that margin. Sodium and potassium on a blood panel are the values that show what is actually happening.
Muscle weakness, numbness or tingling, a slow or irregular pulse, or confusion can all mark potassium that has risen too far, and mean seeing a doctor without delay. Regular use alongside kidney disease or any of those blood-pressure medicines is worth discussing with a doctor first.
