How do you feel? Why did you go to the doctor?
You are in stage 1 hypertension. There are reasons for high blood pressure, and there are side effects to high blood pressure. There may be an underlying reason for the high BP.
Ephedrine is going to make your heart work even harder. One of the side effects of ephedrine is High Blood Pressure. You should already be feeling some effects of the high BP.
Personally, I would advise against it.
Find out what is causing the high BP, see if you can get it lowered...
