Re: why does my son cough so much
Just some anecdotal info...
I switched from Claritin to Zyrtec this spring. Everything was fine and it helped my allergies. After three weeks, though, I started having symptoms of acid reflux, had trouble swallowing, and was constantly coughing. I didn't put the two together since it took a few weeks for the symptoms to appear.
I started doing what I could to treat acid reflux to no avail. And then, out of desperation, I tried switching back to Claritin and off of the Zyrtec. In two days, I was back to normal. My allergies weren't treated quite as well, but it's a much better alternative than the acid reflux.
