Well, made it to the Dentist Wednesday afternoon. He pulled my tooth but it broke off during the procedure so he had to dig the roots out. He put me on Keflex(500mg 4xday/7 days). Yesterday I was pretty sick in class so left early. Not something I’ve ever done before but knew I had my 45 minute drive home. Went straight to bed. Today still taking Keflex got up and noticed my face was covered in blisters! Holy crap! All the way into my hairline! Then started running fever and realized I was reacting to Keflex. So couldnt get Dentist on phone, started benedryl. Less than 1 hr fever broke! Thank goodness for benedryl. So add Keflex to list of no-nos for Arleen.
