Is Benadryl the Best Option for Treating Allergic Reactions?
Dr. Dean Mitchell, Board Certiallergic-reactions-and-benadryl.jpgfied Allergist in NYC, discusses why Benadryl is not the best antihistamine for allergic reactions.
For so many years people have thought that they should take Benadryl for allergic reactions. Its common to get Benadryl in the ER when you are having an allergic reaction and when people go to the drugstore they think Benadryl is the best antihistamine to take to help alleviate their allergies.
Just because Benadryl is the oldest antihistamine doesnt make it the best one to use when you have an allergic reaction. In fact, I rarely recommend using Benadryl for allergic reactions.
Benadryl vs Claritin
This is a non-sedating antihistamine which means it doesnt cross the blood-brain barrier so it doesnt make you tired. It also works quickly. In fact, today they have a Claritin ready-tab which you just put on your tongue and it works instantly. You can carry around these tabs in your wallet if you are prone to getting allergic reactions you cant predict.

There are, though, a lot of things you need to check carefully before you go ahead and administer this drug to your pet.
