What does PEN-FAST stand for

What does PEN-FAST stand for

• A. Penicillin; Five; Anaphylaxis/Angioedema; Severe Cutaneous Adverse Reactions; Treatment
• B. Penicillin; Four; Anaphylaxis/Angioedema; Severe Cutaneous Adverse Reactions; Therapy
• C. Penicillin Allergy; Five Years; Anaphylaxis; Severe Cutaneous Adverse Reactions; Treatment
• D. Penicillin; Five; Asthma/Urticaria; Serious Cutaneous Adverse Reactions; Treatment

Answer: (A)

PEN-FAST is a quick mnemonic used to assess penicillin allergy risk. It breaks down into five elements that guide whether someone with a recorded penicillin allergy might safely proceed with testing or a supervised challenge. Penicillin — refers to history or exposure to penicillin (the allergy label is about penicillin itself). Five — the reaction occurred within the last five years. Anaphylaxis/Angioedema — a history of a life-threatening immediate reaction. Severe Cutaneous Adverse Reactions — history of serious skin reactions such as SJS or TEN. Treatment — the reaction occurred during penicillin treatment (i.e., related to penicillin use). This combination is the established meaning of the acronym: Penicillin; Five; Anaphylaxis/Angioedema; Severe Cutaneous Adverse Reactions; Treatment. Other options mix in different terms (e.g., Four instead of Five, Penicillin Allergy, Asthma/Urticaria, Therapy), which do not fit the recognized components.
