I take Allegra for really bad post nasal drip. Take 180 mg. first thing in morning. It is supposed to be good for 24 hours. However, I have really bad congestion, and often by evening, I am getting little relief.
Does anybody take 180 mg. plus a little more if needed later in the day?
I have taken a half tab (90 mg.) a few times. I am wondering if anybody else has tried this.
