Benadryl Anxiety Reviews

Sun, 04 Sep 2011

Can I die from taking this many. Is it physicly addicting? Sorry about my spelling.

Mon, 18 Jul 2011

I loved these strips. I have had allergic reactions to my own allergy shots. After waiting at the Dr.'s office for 15 minutes after my allergy shot, I leave to go shopping. Sometimes I can feel a little thickening in my throat, similar to when I've had a really bad reaction and had to go to the ER for help, or went back to the Dr.'s office for a shot of epinepherine. When I feel just a small reaction beginning, I have put one of the Benadryl Quick Dissolve Strips on my tongue. I get a pretty fast result and I can continue shopping rather than worrying about a worse reaction.

Now, when I went to buy more of this product, it isn't available at any local stores, or on line at safe sites. Each store tells me that people are coming in and wanting them and getting upset when they can't find them.

Why were these strips taken off the market?

Sun, 21 Mar 2010
Does taking too much Benadryl cause a person to fall asleep and not wake up?
Wed, 01 Sep 2010
It was given to me in a hospital through emergency room, for nauseau. Nusrse said that they use it for that as well. Is true and can it be usedat home for the same?
Thu, 24 Mar 2011
My son is allergic to children's Benadryl. It causes him to develop eye infections (conjunctivitus).
Sat, 30 Apr 2011
I've noticed that it when I am with my partner it makes me sensitive, but I am not able to be aroused. Is anyone else having the same issue. I've been taking it for alergies since I was a teenager. Its the only thing that has ever worked for me.
