For Healthcare Professionals

General

Minoxidil topical (the active ingredient contained in Rogaine Women's) is generally well tolerated. Dermatological adverse events are the only side effects reported more commonly as compared to placebo.

Cardiovascular

Edema, salt and water retention, pericardial effusion, pericarditis, tamponade, tachycardia, and angina have been reported with oral minoxidil. Patients with underlying heart disease may be at increased risk for these or other cardiovascular adverse effects.

Rarely, cardiovascular side effects have included edema, chest pain, blood pressure changes, palpitations, and changes in pulse rate with minoxidil topical therapy.

Local

Despite low levels of systemic absorption, in one study of 35 men using either topical minoxidil 2% twice a day or placebo for 6 months, minoxidil was associated with cardiac changes, such as significant increases in left ventricular end-diastolic volume, cardiac output, and left ventricular mass.

Systemic side effects are uncommon since very little minoxidil is absorbed after topical application. In one study, the serum levels after 2.5 mg twice a day oral versus 2% twice a day topical minoxidil were 32.8 and 1.7 ng per mL, respectively.

Exacerbation of hair loss/alopecia has been reported.

Dermatologic
