When you first step into the world of pharmacovigilance, one of the most fundamental tools you’ll encounter is the Suspected Adverse Drug Reaction (ADR) Reporting Form. This document is the cornerstone of drug safety, allowing healthcare professionals to report potential safety issues to regulatory authorities.
Learning to fill it out correctly is a critical skill. Let’s break down the process using a real-world example, turning a seemingly complex form into a simple, manageable task.
The Four Pillars of an ADR Report
At its core, the ADR form is divided into four main sections. We will use the provided completed form as our case study to understand what goes where.
A. Patient Information: Confidentiality and Clarity
This section is all about the patient, but protecting their identity is paramount.
- Patient Initials: Use initials only (e.g., RK) instead of the full name to maintain confidentiality.
- Demographics: Note the patient’s age at the time of the reaction (45 years), gender (Male), and weight (70 Kgs).
Reaction Details:
- Description: Clearly describe the reaction in simple terms. In our example, the “Patient developed skin rash, itching, and mild swelling on face after taking the antibiotic.”
- Dates: Record the date the reaction started (05/08/2025) and when it stopped (08/08/2025).
- Onset Lag Time: This is the time between starting the drug and the reaction occurring. Here, it was 2 days.
- Treatment & Outcome: Mention any treatment given for the reaction (“oral antihistamine (Cetirizine) was given”) and the final outcome, which was “Recovered.”
B. Suspected Medication(s): The Investigation
This is where you detail the drug(s) you believe caused the reaction.
- Drug Details: List the suspected medication(s) by brand or generic name (Amoxicillin, Amoxclav), dose (625mg), route (Oral), frequency (BD – twice a day), and the indication for its use (Respiratory inf).
- Therapy Dates: Note the start date (03/08/2025) and stop date (05/08/2025) of the suspected drug.
- Dechallenge: This is when you stop the suspected drug to see if the reaction subsides. In our case, the “Drug withdrawn” box is ticked Yes. The positive outcome (recovery) strengthens the suspicion.
- Rechallenge: This involves re-administering the drug to see if the reaction returns. It is rarely done, especially in cases of allergic reactions, and is marked No here.
- Concomitant Medicines: List all other medications the patient was taking at the time, like Paracetamol for fever. This helps rule out other potential causes.
C. Additional Information: The Full Picture
This section provides crucial context. Our example notes: “Patient advised to avoid Amoxicillin in the future and informed about Possible cross-reaction with other penicillin group drugs.” This information is vital for the patient’s future safety.
D. Reporter’s Information: Closing the Loop
This might be the last section, but it’s critically important.
- Your Details: Provide your name (Ananya Kulkarni), profession, and contact information.
- Why It Matters: If the regulatory authority (like an AMC or NCC) finds any missing details or needs clarification, they will contact you. Complete information here makes the report more valuable and actionable.
Key Takeaways for Accurate Reporting
- Timeliness is Crucial: For serious and unexpected adverse events, this report must be submitted to the regulatory authority within 15 calendar days of you becoming aware of it.
- Be Thorough: Every piece of information, from lab data (CBC & LFT were normal) to medical history (No known allergies, non-smoker), helps build a stronger case.
- Download the Right Form: Always ensure you are using the latest version, which you can typically find on your national pharmacovigilance authority’s website (like the PvPI in India).

Learning this process taught me that accurate, timely, and complete reporting isn’t just paperwork; it’s a direct contribution to protecting patient safety and improving the medicines of tomorrow.
