Summary

Stimulant laxatives can cause potassium loss through the gut, and corticosteroids such as deflazacort promote renal potassium excretion. Used together, especially over time, they may produce hypokalemia with muscle weakness or arrhythmias.

What this interaction means in plain words

Bisacodyl and Deflazacort can affect each other. The combination is often manageable, but it may need a change of dose, a change of timing, or extra checks while both are taken.

Bisacodyl belongs to Gastrointestinal Tract; Deflazacort belongs to Miscellaneous.

Evidence level: Low

Why it happens

Additive potassium depletion from intestinal losses (bisacodyl) and mineralocorticoid-related renal potassium wasting (deflazacort).

What to do

Limit bisacodyl to short-term use and check serum potassium if combined use is prolonged. Replace potassium as needed.
