I’ve been taking Claritin on a daily basis for about a year and a half now (because I’m allergic to my cat). I haven’t had a head cold since I started, which is great. A couple of times, though, I have felt rotten–run down–and just slightly snottier than usual. I have assumed that these are times when I had a cold virus, but the excellent drainage provided by Claritin was stopping me from getting congested and fully sick.
Has anyone else had a similar experience? Does anyone agree or disagree with my theory?
