What the FDA labels say
From the Pindolol label · effective 2026-01-12
Although beta-blockers should be avoided in overt congestive heart failure, if necessary, pindolol tablets can be used with caution in patients with a history of failure who are well-compensated, usually with digitalis and diuretics.
Pindolol tablets have been used with a variety of antihypertensive agents, including hydrochlorothiazide, hydralazine, and guanethidine without unexpected adverse interactions.
At the first sign or symptom of impending cardiac failure, patients should be fully digitalized and/or be given a diuretic, and the response observed closely.
If cardiac failure continues, despite adequate digitalization and diuretic, pindolol tablets therapy should be withdrawn (gradually, if possible).
