Understanding what an adverse drug reaction (ADR) means is the first step toward managing your health safely when starting a new prescription, over-the-counter medicine, or complementary health product. An adverse drug reaction is any unwanted, unintended, or harmful response to a medication that occurs at normal doses used for prevention, diagnosis, or treatment.
While all effective medicines carry potential risks alongside their benefits, tracking and reporting unusual symptoms helps protect both you and the broader community in South Africa.
Medical Disclaimer & Safety Warning: This guide is for educational purposes only and does not constitute medical advice or diagnosis. Never stop taking a prescribed medication or adjust your dosage without consulting your doctor or dispensing pharmacist. If you experience severe, life-threatening symptoms, seek emergency medical care immediately.
Quick answer: when and how to report a suspected side effect
If you suspect that a medicine, vaccine, or health supplement is causing an unexpected physical or mental symptom, you can report it immediately. You do not need scientific proof or a doctor’s confirmation that the medication was the sole cause—a reasonable suspicion is enough to file a report.
In South Africa, reporting can be done directly by patients, caregivers, or healthcare professionals through the South African Health Products Regulatory Authority (SAHPRA) using the mobile Med Safety App, the web-based e-Reporting portal, or an Adverse Drug Reaction (ADR) paper form at your local clinic or pharmacy.
What information to record
- Symptom onset: Note the exact time and date symptoms began relative to when you took the medication.
- Product details: Write down the exact brand name, active ingredients, dosage, and batch/lot number from the packaging.
- Symptom specifics: Describe what you felt, where on your body it occurred, how long it lasted, and whether it improved when the medicine was stopped or reduced.
- Concurrent products: Keep a complete list of all other prescription drugs, over-the-counter pills, traditional medicines, or vitamin supplements taken around the same time.
Where reporting fits into medicine safety
Every report submitted contributes directly to national pharmacovigilance—the science of collecting, monitoring, and evaluating medicine safety data. In South Africa, SAHPRA monitors these reports to identify previously unknown side effects, detect rare safety signals, issue public health alerts, or require pharmaceutical manufacturers to update Patient Information Leaflets (PILs) with clearer warnings.
Who can report a side effect or adverse drug reaction?
Anyone in South Africa who observes or experiences an unwanted effect from a health product can submit an ADR report. You do not need to wait for a medical practitioner to do it for you.
- Patients and Consumer Caregivers: Individuals experiencing symptoms, or family members reporting on behalf of children, elderly relatives, or dependants.
- Healthcare Professionals: Doctors, nurses, pharmacists, dentists, and community health workers in both private and public healthcare sectors.
- Market Authorization Holders (MAHs): Pharmaceutical companies licensed to manufacture or distribute medicines in South Africa.
What information to record
- Patient demographics: Record the patient’s age, sex, weight, and general health background (patient identity is kept strictly confidential).
- Reporter details: Include your contact information (phone number or email address) so safety officers can follow up if necessary.
- Clinical observer status: Note whether the symptom was self-observed or evaluated by a healthcare practitioner.
Where reporting fits into medicine safety
Consumer reporting bridges the gap between controlled clinical trials and real-world medicine use. Clinical trials often involve limited patient groups over fixed timeframes. Once a medicine is available across South Africa, real-world reporting helps identify rare adverse reactions, unintended interactions with local traditional herbal remedies, or variations across diverse populations.
What information should you collect before reporting?
Gathering accurate information before opening the reporting app or visiting your pharmacist ensures your report is complete, clear, and actionable for safety assessors.

+----------------------------+ +----------------------------+ +----------------------------+
What information to record
- Package specifics: Copy down the exact medicine name, strength (e.g., 500mg), dosage form (tablets, liquid, ointment), batch/lot number printed on the box, and expiry date.
- Dosing schedule: Document how much you took, how often, and whether it was taken with food or on an empty stomach.
- Action taken: Note if the dose was paused, reduced, or continued, and whether any treatment (like an antihistamine or pain reliever) was given to manage the reaction.
Where reporting fits into medicine safety
Precise batch numbers and timeline records allow SAHPRA pharmacovigilance experts to evaluate whether a reaction is linked to a specific manufacturing batch defect or an inherent risk of the active drug compound.
How to report through SAHPRA, Med Safety or the ADR form
South Africa offers several accessible pathways to submit an adverse drug reaction report:
- The Med Safety App: Download the free Med Safety app (available on iOS and Android). Select South Africa as your region, create a profile, and log side effects directly from your smartphone—even offline.
- SAHPRA Online e-Reporting Portal: Visit the official SAHPRA web portal to submit a digital ADR form directly from a computer browser.
- Paper/PDF ADR Form: Obtain an official paper reporting form from a public clinic, hospital pharmacy, or private healthcare provider, complete the fields, and return it to the facility or email it to SAHPRA’s dedicated pharmacovigilance unit.
What information to record
- Primary contact details: Ensure your phone number and email address are correct for potential confirmation.
- Event outcome: Detail whether the reaction has resolved, is improving, remains ongoing, or resulted in hospitalization or time off work.
Where reporting fits into medicine safety
All submitted reports feed directly into South Africa’s National Pharmacovigilance Centre. From there, anonymised data is shared with the World Health Organization (WHO) global database (VigiBase), contributing to international medicine safety intelligence.
What counts as a serious or unexpected side effect?
Side effects range from mild, temporary discomforts (like mild drowsiness or slight nausea) to severe, life-threatening medical emergencies. Knowing the difference helps you decide whether to file a routine report or seek urgent emergency intervention.
Red-flag symptoms
Seek immediate emergency medical assistance if you or someone you are caring for experiences any of the following critical symptoms after taking a medicine:
- Severe allergic reaction (Anaphylaxis): Swelling of the face, lips, mouth, tongue, or throat causing difficulty swallowing or breathing.
- Respiratory distress: Sudden shortness of breath, severe wheezing, or feeling like your chest is tightening.
- Cardiovascular distress: Severe chest pain, rapid or irregular heartbeat, or sudden collapse.
- Neurological changes: Seizures, loss of consciousness, sudden extreme confusion, or severe dizziness/fainting.
- Severe cutaneous reactions: Widespread, rapidly spreading skin rash with blistering, skin peeling, or raw sores around the eyes, mouth, or genitals.
- Psychiatric changes: Sudden suicidal thoughts, acute hallucinations, severe agitation, or profound panic.
- Unexplained bleeding: Severe, uncontrollable bleeding, vomiting blood, or passing dark, tarry stools.
- Signs of severe toxicity: Unresponsiveness, extreme lethargy, or pinpoint pupils (suspected overdose).
When to contact a doctor, pharmacist, or emergency service
- For Red-Flag Emergencies: Call local emergency services immediately (such as 112 from any mobile line, 10177, Netcare 911 on 082 911, or ER24 on 084 124) or go directly to the nearest hospital casualty unit.
- For Non-Emergency Reactions: Schedule a prompt consultation with your GP or speak to your dispensing pharmacist. They can assess your symptoms, advise on whether to adjust treatment safely, and submit an official report on your behalf.
What happens after a report is submitted?
Once an ADR report is logged via the Med Safety App, e-Portal, or paper form, it enters a structured evaluation pipeline handled by pharmacovigilance specialists.

+----------------------------+ +----------------------------+ +----------------------------+
What information to record
- Unique reference number: Save the confirmation or reference code generated upon submitting your report via the app or web portal.
- Professional clinical notes: Keep copies of any clinical letters, blood test results, or doctor notes related to the reaction in case SAHPRA requests further details.
Where reporting fits into medicine safety
Individual reports act as building blocks for long-term safety oversight. When multiple reports indicate a pattern or “safety signal,” SAHPRA initiates an in-depth review. Actions may include updating the official package insert to warn high-risk patients, restricting medicine availability to specific medical conditions, issuing safety alerts to South African healthcare workers, or recalling affected product batches from pharmacies.
