How much antihistamines should I take if I'm not under a doctor's care?
Hi guys, I posted a few days ago asking for advice on how to manage my hives until I see an allergist in 2 weeks. I got lots of good suggestions, some of which have sort of helped but not that much.
I have started taking 1 Allegra or Claritin and 1 Pepcid in the morning, and 1 Zyrtec and 1 Pepcid at night. It helped on the first day, although for some reason I got an upset stomach that night and vomited. However, since then, my hives have come back. It's only been a couple days, so maybe it will take a bit for the antihistamines to build up in my system and be more effective? I had to sleep with long sleeves and leggings last night because I was so itchy, and I ended up taking a cold bath with colloidal oatmeal at 1am because of how bad it was.
Anyways, on the 3rd day of this regimen I got a splitting headache and was super tired. I've been in bed most of the day. I assume it's a side effect of the antihistamines, so my question is, should I stop taking them? I can't imagine going 2 weeks unmedicated until I see the allergist but I'm worried I'm going to overdose or something. I honestly feel like I need to take more Allegra or Claritin in the afternoon to actually help with the hives but 3 pills a day seems like a lot.
