Warning! Interaction Between Propranolol + Minoxidil (rogaine)

DAVE804 Says:

Hi, I was taking propranolol to help with anxiety. Dosage was dependent on how bad anxiety was on any given day. I was struggling with self-esteem, so visited a hair clinic for help with thinning hair. One of the things that I was given by the clinic was Minoxidil 10%, which is a product proven to help stimulate hair regrowth (see Rogaine). This product was applied to the scalp twice a day, morning and night. Within a few days of using the Minoxidil, I started to feel chronic fatigue, which literally knocked me off my feet. I also went into a really deep depression. Something was not right! I took to Dr Google lol. Very quickly, I found that chronic fatigue and depression are two symptoms of very low blood pressure. Fortunately, I own a BP monitor and took some readings. My usual resting BP is around 115/80, so very healthy. The average reading that I took this time was 97/69. My BP had crashed, hence the onset of the above symptoms. You may argue that 97/69 is still in the 'healthy range'. However, it is NOT healthy if my BP takes such a drop!

See below from the Mayo Clinic website:
"A sudden fall in blood pressure can be dangerous. A change of just 20 mm Hg — a drop from 110 mm Hg systolic to 90 mm Hg systolic, for example — can cause dizziness and fainting."

I discontinued the Minoxidil right away and felt a lot better the very next day. Granted, that Minoxidil 10% is a stronger solution that the Rogaine 5% solution but that is what the hair clinic gave me and I trusted them! If you look up Minoxidil, it was developed as a treatment for high blood pressure, which I hadn't even realized. I had even told the hair clinic that I was using Propranolol but they did not mention that there could be any interactions!

Basically, I was using two separate BP medications!! I just wanted to put this info out there, in case it helps anyone that finds themselves in the same predicament.

Best wishes and stay healthy,
