Hi There. I Was Having An Allergic Reaction At A

Hi there. I was having an allergic reaction at a friends house so I took an Allegra. Then I got home and took my normal pills, which include an Allegra and a Singulair, forgetting I had taken the Allegra three hours earlier. I also took a Benadryl because I was having a pretty bad reaction.

So overall, I have taken two allegras, a Singulair, and a Benadryl.

My allergic reaction is gone but I am freaked out that I took way too much. Should I be worried? What can I do?
