Can you take Benadryl for allergic reactions?

This would depend on your allergic reaction and you individually. Benadryl is an anti-histamine. Some people with certain health conditions or who are on certain medications cannot have anti-histamine medicines. Also, if your tongue, lips, throat, or eyes swell up a lot or you are having trouble breathing- you should go to the emergency room. If none of the above apply- and you are having a mild episode of hives or a mild rash or if you have seasonal Allergies, you should be fine.
