Summary
Beta blockers given with methyldopa may cause additive blood pressure lowering. Reports describe severe hypertension when a nonselective beta blocker is used during methyldopa withdrawal, because of unopposed alpha stimulation.
What this interaction means in plain words
Methyldopa and Pindolol 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.
Why it happens
Additive antihypertensive effect; beta blockade unmasks unopposed alpha-adrenergic vasoconstriction if methyldopa is stopped abruptly.
What to do
Monitor blood pressure and heart rate. Avoid abrupt methyldopa discontinuation, and taper the beta blocker first if both are being withdrawn.
What to ask your pharmacist
