6 Guidance For NHS Grampian Staff On Antibiotic Choice For Patients With Penicillin Hypersensitivity Introduction The phrase allergic to penicillin is commonly seen in medical notes and on medicine charts. The diagnosis of penicillin allergy is often simply accepted without obtaining a detailed history of the reaction. It has been reported that a significant percentage (up to 90%) of patients labelled as penicillin allergic are not truly allergic to the drug (1, 2). As a result, penicillins are unnecessarily withheld as a treatment option for these patients, which may subsequently affect their clinical outcomes. Alternatives to penicillins may be broader spectrum, more costly, and have the potential for more adverse reactions (including Clostridium difficile), and induction of antimicrobial resistance (3,4). The in-patient antibiotic cost of managing a patient with an allergy to penicillin has been reported to be more than 60% higher than that of a patient who can tolerate a penicillin (5). What is the True Incidence of Penicillin Allergy? General hypersensitivity reactions (e.g. rashes) to penicillin occur in between 1% and 10% of exposed patients but true anaphylactic reactions (which can be fatal) occur in less than 0.05% of treated patients (6). Hypersensitivity to penicillin gives rise to immediate reactions including anaphylaxis, angioedema, urticaria, and some maculopapular rashes. Late reactions may include serum sickness-like reactions and haemolytic anaemia (7). Individuals with a history of a minor rash (i.e. non-confluent, non-pruritic rash restricted to a small area of the body) or a rash that occurs more than 72 hours after penicillin administration are probably not allergic to penicillin and in these individuals a penicillin should not be withheld unnecessarily for serious infections; the possibility of an allergic reaction should, however, be borne in mind. Other beta-lactam antibiotics (including cephalosporins) can be used in these patients (6). Please note that patients who have a vague history of symptoms or gastro-intestinal intolerance are probably not truly allergic to penicillins. Clinical judgement must be used if adequate information about a patient s history of penicillin allergy is difficult to obtain. Who is at risk? Patients with a history of atopic allergy (e.g. asthma, eczema, hay fever) are more likely to be allergic to penicillins (6). Recording Drug Allergies NHS Grampian policy states that any known drug/medicine sensitivity should be entered in the appropriate box on the prescription and administration record (PAR) at the time of admission or as this information becomes available. The information recorded should include the drug name and the nature of the reaction. UNCONTROLLED WHEN PRINTED Review Date: July 2017 Identifier: NHSG/Guid/PenA/MGPG

7 Who should not be prescribed or administered penicillins? Individuals with a history of immediate hypersensitivity following penicillin administration, clinically recognisable by features of urticaria, laryngeal oedema, bronchospasm, hypotension or local swelling within 72 hours of administration should NOT receive a penicillin. Patients who are allergic to one penicillin will be allergic to all because the hypersensitivity is related to the basic penicillin structure. In cases of intolerance to penicillins (e.g. gastrointestinal upset) or development of a rash 72 hours after administration, penicillins/related antibiotics should not be withheld unnecessarily in severe infection but the patient must be monitored closely after administration. Treatment options in these patients should be discussed with medical microbiology or an infection specialist. Are there situations where cephalosporins or other beta-lactam antibiotics can be prescribed for patients with penicillin hypersensitivity? The incidence of cross-reactivity to cephalosporins in penicillin-allergic patients is 0.5% - 6.5% (6). Second and third generation cephalosporins are less likely to be associated with cross reactivity as they have different side chains to penicillin. If a cephalosporin is essential (e.g. in life threatening infections) in these patients because a suitable alternative antibacterial is not available, then cefixime, cefotaxime, ceftazidime, ceftriaxone, or cefuroxime can be used with caution. Avoid cefalexin and cefradine (6). Carbapenems (e.g. meropenem, ertapenem) and monobactams (e.g. aztreonam) should also be used with caution in patients with a history of an immediate hypersensitivity reaction (6); very low rates of cross-sensitivity have been reported (9,11). Which antibiotics can I use in a penicillin allergic patient? Antibiotics which are unrelated to penicillins and safe to use include: Tetracyclines (e.g. doxycyline) Aminoglycosides (e.g. gentamicin) Macrolides (e.g. clarithromycin) Clindamycin Sulphonamides (e.g. co-trimoxazole) Trimethoprim Metronidazole Quinolones (e.g. ciprofloxacin) Vancomycin or teicoplanin Fosfomycin What should be prescribed empirically for truly penicillin allergic patients? See Grampian Joint Formulary for full guidelines. For information on which antibiotics should be avoided in penicillin allergy, those that should be used with caution, and those that are safe see Appendix 1.
