TOPLINE:

In a large retrospective study of patients with androgenic alopecia or other nonscarring hair loss, treatment with low-dose oral minoxidil (LDOM) was not associated with an increased risk for tachycardia.

METHODOLOGY:

Researchers conducted a study of 524,522 patients with androgenic alopecia or other nonscarring hair loss, who did not have a history of hypertension, tachycardia, or arrhythmia (about 62% White; 9% Black; 10% Hispanic or Latino individuals) from the TriNetX database from 2004 to 2024.

Of those patients, 9267 were on LDOM (≤ 5 mg/d minoxidil, used off-label for treating hair loss); the rest were minoxidil-naïve.

In the LDOM vs control group, patients were older (mean age, 45.5 years vs 39.8 years; P < .0001) and there were more men (33% vs 19%, P < .0001).
