Read this before you start. The only FDA approved oral minoxidil is for severe high blood pressure, at doses many times higher than the dose used for hair. That label carries a boxed warning for fluid building up around the heart, which can become dangerous, and for worsening chest pain. Hair loss dosing is far lower and no FDA approved product exists at that dose, so the risk at this dose has not been established. Your clinician reviews your heart history before prescribing it.
Finasteride is FDA approved for male pattern hair loss. Oral minoxidil is not approved for hair loss at any dose. Using it this way is off-label, which means the FDA has not reviewed it for this purpose.
Tell your care team straight away if you get chest pain, shortness of breath or trouble lying flat, a racing heartbeat, sudden weight gain or swelling in your hands, feet or face, or you faint. Also tell us if you get depression or thoughts of harming yourself, or breast lumps, pain or discharge.
