What is the dosage for potassium supplements-oral?

  • The usual recommendation for treatment of hypokalemia in adults is 20-40 mEq 2 to 4 times daily.
  • The dose for prevention is 20 mEq daily.
  • Oral potassium is usually taken with meals and fluids to prevent intestinal problems.
  • Controlled release tablets should be swallowed whole.

Which drugs or supplements interact with potassium supplements-oral?

: Angiotensin converting enzyme (ACE) inhibitors (for example, enalapril [Vasotec]), angiotensin receptor blockers (ARB) drugs (for example, valsartan [Diovan]), and certain diuretics (for example, spironolactone [Aldactone] and triamterene [Dyrenium]) increase potassium levels, causing high potassium levels in the blood when combined with potassium supplements. Potassium blood levels should be measured regularly in these patients.

Salt substitutes (for example, Mrs. Dash) often contain potassium. Therefore, using salt substitutes while taking potassium supplements may lead to high levels of potassium in the blood.

Drugs that slow transit of food through the intestine, for example, atropine and loperamide (Imodium), may delay passage of potassium tablets through the digestive system and result in ulceration or narrowing of the small intestine.
