Cefdinir far more likely. Moreover, cefdinir belongs to a category of antibiotics called cephalosporins. Very commonly used. If your allergic to any one member of the class, you’re likely allergic to all. Tell future docs that your allergic to “cephalosporins”.

Very concerned. Started Benadryl 25mg every 6 hrs& Prednisone. I start feeling like I could pass out! Dr. wants me to take it to reduce swelling in cyst and hives from possibly Cefdinir. Any advice or just tough it out for next 5 days?

Taking Cefdinir and Clindamycin for infected cyst. ER visit today with hives. Dr. said no Clindamycin. Gave me Prednisone 60mg, one dose tomorrow, also Benadryl 25mg for 5 days. Im concerned that Cefdinir is all I can tolerate, surgery 5/11?

I have a red splotchy kind of rash over n around the sight of a tegaderm bandage for a rib tattoo. Doesn't itch but I also have nasal congestion like an allergic reaction that benadryl helped. No swelling/hives. Should I be concerned? Home treatment?
