Topical Minoxidil and Blood Pressure

Dr.,

Do you believe that applying minoxidil topically can appreciably lower blood pressure, even by just a few mmHg?

Yes, it can. Minoxidil is a blood pressure lowering medication if you take it orally. Topical application, when used correctly, should not have systemic side effects of lowered blood pressure, but it can happen if you use it frequently and apply higher amounts than are recommended.
