Suspected Agent(s)

(Create a separate block for each suspected drug. Mark unknown fields as "Unknown" when they affect causality assessment.)

Reaction History

[Narrative summary of the event: patient's account, temporal relationship to exposure and dose number, symptom progression and peak severity, treatments given and response, and resolution timeline] (Include brief direct patient quotes only for subjective symptoms that influence risk assessment. Note pertinent negatives that inform classification.)

Prior Tolerance and Cross-Exposure

• Prior exposures to same drug before index reaction: [tolerated / not tolerated / none / Unknown] (Include number of prior courses if known)
• Subsequent exposures after reaction: [Yes—outcome / No / Unknown] (Include accidental or supervised rechallenge details)
• Tolerance of related drugs: [List specific agents in same or cross-reactive classes and outcomes]
• Prior allergy testing or procedures: [skin testing / graded challenge / desensitization / patch testing / none] — [Results and dates if available]

Contributing Factors

(Include only if relevant to causality or future risk; omit section if not applicable)

• Intercurrent illness: [Present / Absent / Unknown] — [Details]
• Conditions mimicking allergy: [chronic urticaria / anxiety / other / none] — [Details]
• Cofactors: [exertion / alcohol / NSAIDs / none] — [Details]
• Comorbidities affecting severity risk: [asthma / cardiovascular disease / mast cell disorder / beta-blocker use / none] — [Details]

Objective Data

(Include when available; omit section if none)

• Photos: [Yes—stored in media / No]
• Labs: [CBC with differential / Tryptase / LFTs / Other] — [Results and dates]
• Outside records reviewed: [Sources and dates]; [Key corroborating details]

Assessment

(Create a separate assessment block for each suspected agent, ordered by severity and clinical impact. Use probabilistic language unless supported by testing or clear criteria.)

[Agent 1]: [Generic (Brand)]

• Classification: [Immune-mediated hypersensitivity (drug allergy)—suspected or confirmed / Non-immune intolerance or side effect / Toxicity-related effect / Reaction type uncertain]
• Causality: [definite / probable / possible / unlikely / uncertain] — [Key supporting factors: temporal relationship, dechallenge, alternative explanations, rechallenge history, objective evidence]
• Differential: [Non-drug causes or other drugs in exposure window if plausible]

[Agent 2]: [Generic (Brand)]

(Include additional assessment blocks as needed)

• Classification: [Immune-mediated hypersensitivity (drug allergy)—suspected or confirmed / Non-immune intolerance or side effect / Toxicity-related effect / Reaction type uncertain]
• Causality: [definite / probable / possible / unlikely / uncertain] — [Key supporting factors]
• Differential: [Non-drug causes or other drugs in exposure window if plausible]

Plan

• Medication guidance: [Drugs and classes to avoid]; [Safe alternatives with cross-reactivity rationale]; [If essential drug needed: next steps—referral, graded challenge, or desensitization] (Do not imply procedures were performed unless documented)
• Evaluation plan: [Allergy/Immunology or Dermatology referral if indicated]; [Planned testing: skin testing / drug provocation / patch testing]; [Contraindications or precautions if applicable]
• Monitoring and follow-up: [What to monitor]; [Return precautions]; [Follow-up timing and responsible clinician]
• Patient education: [What to avoid]; [Safe alternatives]; [When to seek urgent care]; [Epinephrine autoinjector education if prescribed]; written instructions provided [Yes / No]

EHR Updates Performed

(Explicitly document allergy list changes. If a label is removed or downgraded, include supporting evidence. Omit subsection if no changes made.)

• Agent: [Drug name] — Action: [Added / Updated / Removed / Downgraded] — Reaction: [Concise description] — Type: [allergy / intolerance / adverse effect] — Severity: [mild / moderate / severe / Unknown] — Reaction date: [Date or Unknown] — Comments: [Timing details, safe alternatives, testing results]
