Methylprednisolone and Potassium, a synergy.
High-dose or pulse methylprednisolone can disturb potassium handling and has been associated with clinically relevant rhythm concerns in vulnerable patients. Potassium supplementation can correct confirmed hypokalemia, but it should be guided by lab results.

Synergy
What is happening. High-dose or pulse methylprednisolone can disturb potassium handling and has been associated with clinically relevant rhythm concerns in vulnerable patients. Potassium supplementation can correct confirmed hypokalemia, but it should be guided by lab results.
Mechanism. Methylprednisolone can alter renal potassium excretion and transcellular potassium balance during high systemic exposure. Potassium supplementation restores serum potassium but can overshoot if kidney function is impaired or the steroid effect resolves.
Recommendation. Have potassium monitored during high-dose, IV pulse, or prolonged methylprednisolone therapy, especially if you have kidney disease, heart disease, or take diuretics. Do not self-treat with high-dose potassium unless your potassium level and kidney function are known.
