Hi ~ Usually the itching will stop after you've been on it awhile, BUT if you notice that your throat is itching or your tongue becomes swollen, STOP taking it and get to the doctors/hospital.
Also if the itching is too bothersome, you can take some benadryl to help. This is what I was told anyway.
if you have hives tho, I think I'd quit taking it and call my doctor for a switch to something else. Best of luck & God bless. Hugs, Lee
