Why do they add DYE to Benadryl and the sell a DYE FREE version?

by Admin on February 2, 2010

For years, taking Benadryl caused me to have an allergic reaction. Doctors thought this was so humorous, but it wasn’t until last year that a doctor said "Hey, maybe you should try the dye free benadryl" and sure enough, I was allergic to the dye.

So I’ve been wondering, ever since . . . Why would they add dye in the first place if people are allergic to it? Why not just sell a dye free version?

Very good question, and I have wondered the same thing. From what I hear, it is actually pretty common for people to react to the dye that Benedryl uses. I can only guess that they use the dye to try to make their product easily identifiable if the tablets are loose (maybe so that if someone is having a severe allergic reaction they can be sure what pill is what in a travel pill case). I prefer the dye-free, but I sometimes cannot find that version and settle for the bright pink version.

Exactly! My daughter is allergic to red and blue food dye, so guess what’s in Benadryl! This one really had me scratching my head in puzzlement.

We have to go to Walgreen’s to find the dye-free childrens Benadryl. Can’t find it anywhere else. Funny, isn’t it?

I guess most of the people who take Benadryl don’t take it for food dye allergies….
