Ancef is an antibiotic commonly used in surgeries to combat infection. I’m also allergic to penicillin but the ancef rash was horrible.
If you are allergic to penicillin toj have a 1-3% risk of allergy to an Ed (cephalosporins). If you have a phyla is to PCN you should never be given cephalosporins.
That rash looks to me like SJS and is a low risk complication of literally every vaccine and medication. It appears we have people eagerly hoping vaccines cause damage when the fact is there are scant case reports over millions and tens of millions of administrations.
