Cephalosporin Antibiotic Medication
Cephalosporins: These are antibiotics that have a very broad spectrum of use for many different bacterial infections. They are often used first or second line for many common infections and have to be used with care in patients with allergies to penicillin or other cephalosporins. They can treat skin, respiratory, urinary and sexually transmitted infections among many others. ...Read more
Cephalosporin rx: Older studies suggested that there was a 5-7% risk of having a reaction to a cephalosporin if you had a history of penicillin allergy. However, there have been recent studies indicating that the newer cephalosporins are structurally different enough that the risk of cross reaction is quite low, even eliminating the need to test for penicillin allergy prior to administering the cephalosporin. ...Read more
Was just prescribed a cephalosporin antibiotic along with diflucan (fluconazole). When is the best time to take the diflucan (fluconazole) tab? Day 1 of the antibiotics? Thanks!

Hello, What antibiotics should I take for abortion, and when should I start taking them? Should I take only cephalosporin? Or mitronidazole
Usually yes: >90% of the people allergic to penicillin would have no problem with cephalosporin. The newer the generation, the less likely the reaction.

I am g6pd deficient. I had a severe reaction to cephalosporin. Should this medication be avoided since I am g6pd deficient or is this another reaction that has nothing to do with my g6pd deficiency?
Not G6PD Deficiency: The g6pd deficiency association's web site, g6pd. Org, has lists of unsafe drugs and foods for people with g6pd. (not cephalosporins) in g6pd deficiency, if a drug or food causes oxidant stress, hemolytic anemia, or breakdown of red blood cells, can occur. Cephalosporins can be associated with allergic reactions and rarely with hemolytic anemia, but the reason for the hemolysis is different. ...Read more
