      Drug Name Betamethasone Magnesium hydroxide
      Mechanism Hypokalemia Increases the risk of hypokalemia (laxatives can cause loss of electrolytes)
      Key Mechanism Factor 1
Factor Name Hypokalemia
Factor Description Hypokalemia is a condition in which the amount of potassium in your blood is lower than normal. If you are mildly hypokalemic, you may not have any signs or symptoms, but severe hypokalemia may have the following symptoms: fatigue, constipation, frequent or heavy urination, muscle cramps or skin tingling, muscle weakness, and a fast or irregular heartbeat.
      Mechanism Description
  • Increased risk of hypokalemia by the combination of Betamethasone and Magnesium hydroxide 

Recommended Action
      Management In general, laxatives should only be used on a short-term, intermittent basis in recommended dosages. During concomitant therapy with corticosteroids, particularly if fludrocortisone or large doses of a glucocorticoid or adrenocorticotropic agent is given, patients should be counseled to recognize potential signs and symptoms of hypokalemia such as fatigue, myalgia, and muscle weakness. If maintenance of bowel regularity is required, patients should be advised to exercise and increase fiber in the diet and/or consider the use of bulk-forming laxatives.
