Allegra never worked for me.
It suddently kicked in for me by taking it for 3 days straight. Now it works quite well. I made an appointment to see the doctor for something stronger but once the allegra started working I cancelled it. I'm not giving my doctor $75.00 plus the cost of the prescription to tell me, "Yes, it looks like you have allergy issues." It's already close to $100.00 to get my blood tested for cholesterol and make sure my meds are not effecting my liver. My doc owns his own lab so it's ching ching for him there too.
Insurance won't pay for anything. I think I'll move to Canada.
