I’ve Been Using Rogaine and Got a Headache from It. Should I Stop Using It?

A headache could be a sign of reduced blood pressure from the Rogaine (minoxidil), so I recommend speaking with your doctor and to get your blood pressure checked out. Minoxidil was originally developed as a treatment for high blood pressure, so if you have normal blood pressure and the blood pressure becomes low while on the drug, then you can get headaches as the first symptom of the medication.
