It may be alright: It may be alright, but why do you want to take Benadryl (diphenhydramine) after energy drink most energy drinks have caffine in quite high dose and Benadryl (diphenhydramine) is sedating.So some stimulant effect of the energy drink will be neutralise.

A female asked:

Is it okay to take benadryl after drinking an energy drink a couple hours before?

Okay: Yes it is okay to take benadryl 2 hours after having an energy drink. Benadryl does make some people drowsy. The energy drink may contain caffeine that makes many alert. So if you are taking the benadryl for sleep, it might not be effective. Benadryl will still be effective if you are taking it for congestion.
