I have been put on minoxidil 5% a week ago. Broke out with rash and now my whole face is swollen and I have a lymphanode at the back of my head that popped out. Prior to this I had been using minoxidil 2%. l am a 34 year old female.
You should see a doctor. You could have had a reaction to the higher strength drug and may have to stop it. This is a known severe allergic reaction of minoxidil (see here for more).
