Oral Minoxidil and Retatrutide Safety Considerations

Cardiovascular Effects

Fluid retention and edema occur commonly with oral minoxidil, typically requiring concomitant loop diuretic use, and reflex tachycardia is expected, generally necessitating beta-blocker co-administration, according to the American Heart Association 1
The American College of Cardiology recommends monitoring baseline and periodic blood pressure and heart rate measurements when using minoxidil and retatrutide together, as minoxidil causes reflex tachycardia while retatrutide may also increase heart rate 1

Volume status assessment is critical since minoxidil causes sodium and water retention while retatrutide can cause dehydration through GI effects, as suggested by the American Heart Association 1
The American College of Cardiology recommends avoiding abrupt discontinuation of minoxidil, particularly if beta-blockers are being used concurrently, due to the potential for rebound hypertension 2

Hypertrichosis occurs in up to 93% of patients on oral minoxidil, but is typically the desired effect when used for hair loss, according to the American Academy of Dermatology 2
