I Took 9daya If Flagyl And Capro To Treat Diviticulitis.

I took 9daya if flagyl and Capro to treat diviticulitis. It was ordered for 10 days but I stopped both antibiotics because I developed hives -swelling if my eyes on day 9. I began taking Benadryl and and the 3rd day of Benadryl my hives were gone so I stopped the Benadryl. The next morning I woke up with worse hives so I took Benadryl and prednisone. My question is how long will it take for these m eds to clear my body and for the hives to completely go away
