What the FDA labels say
From the Minoxidil label · effective 2026-08-25
Minoxidil should be reserved for hypertensive patients who do not respond adequately to maximum therapeutic doses of a diuretic and two other antihypertensive agents.
Minoxidil must be administered under close supervision, usually concomitantly with therapeutic doses of a beta-adrenergic blocking agent to prevent tachycardia and increased myocardial workload.
The ability of beta-adrenergic blocking agents to minimize papillary muscle lesions in animals is further reason to utilize such an agent concomitantly.
From the Carvedilol (Coreg) label · effective 2026-07-31
COREG may be used with caution, however, in patients who do not respond to, or cannot tolerate, other antihypertensive agents.
