The so-called delabeling of penicillin allergies, doctors say, would have major health impacts: faster and more effective treatments for people who have spent their lives avoiding penicillin and ...
The main disadvantage however, is that patients can be allergic to penicillin based materials with a severe anaphylactic reaction occurring. Despite this, it is still commonly used due to it being highly cost effective and relatively safe. Alternative antibiotics include Erythromycin, cephalosporin and several others. [11]
Serum sickness is a type III hypersensitivity reaction that occurs one to three weeks after exposure to drugs including penicillin. It is not a true drug allergy, because allergies are type I hypersensitivity reactions, but repeated exposure to the offending agent can result in an anaphylactic reaction.
Identifying an allergy to penicillin requires a hypersensitivity skin test, which diagnoses IgE-mediated immune responses caused by penicillin. This test is typically performed by an allergist who uses a skin-prick and intradermal injection of penicilloyl-polylysine, a negative control (normal saline), and a positive control ( histamine ).

Anaphylaxis to penicillin or cephalosporins occurs only after it binds to proteins inside the body with some agents binding more easily than others. [15] Anaphylaxis to penicillin occurs once in every 2,000 to 10,000 courses of treatment, with death occurring in fewer than one in every 50,000 courses of treatment. [15]
If the tonsillitis is caused by group A streptococcus, then antibiotics are useful, with penicillin or amoxicillin being primary choices. [1] [15] Cephalosporins and macrolides are considered good alternatives to penicillin in the acute care setting. [1] [36] A macrolide, such as azithromycin or erythromycin, is used for people allergic to ...
