can the topical application of this drug lower the blood pressure &lead to shock?

I think thats a little bit extreme, maybe if you drank a few bottles of it, but otherwise not really. It may temporarily slightly increase your heart rate. Don't worry about it mate. It can't be that bad its avaliable without prescription, if it was a killer like heroine it wouldnt be availiable. Joe

Hi Medico

Minoxidil has very little side effects to worry about.

The following is from Regaine web site http://www.regaine.co.uk/men/about_howitworks.asp

How it works

Regaine® works by increasing the supply of blood and nutrients to your hair follicles, helping to strengthen existing hair and stimulate secondary growth. This process produces thicker, longer, more-visible hair.

It contains the active ingredient Minoxidil which has been shown to help prevent further hair loss in 4 out of 5 men and stimulate regrowth without affecting male hormones. Because it has limited side effects and has a good safety record , you can buy Regaine® without needing a prescription.
