Summary
Thiazide diuretics are routinely combined with minoxidil, which causes sodium and water retention, and they add to the blood pressure lowering effect. The combination can increase the risk of hypotension and electrolyte disturbances.
What this interaction means in plain words
Bendroflumethiazide and Minoxidil have a small, usually unimportant interaction. Most people can take both; the pharmacist may still mention it so that any unexpected effect is recognised.
Why it happens
Complementary pharmacodynamic effects: thiazide natriuresis counters minoxidil-induced fluid retention while both lower blood pressure.
What to do
Monitor blood pressure, weight and serum potassium and sodium when starting or changing doses. Adjust diuretic dose to control edema.
