Medical Disclaimer: This guide is for informational and educational purposes only and does not constitute formal medical advice. If you or someone you care for is experiencing severe, life-threatening symptoms, seek immediate emergency medical attention. Never stop, start, or alter any prescription medication without directly consulting a qualified doctor or pharmacist.
When starting a new treatment—whether it is a prescription medicine, over-the-counter painkiller, vaccine, or herbal supplement—it is common to experience unexpected physical or mental symptoms. However, healthcare professionals and medical regulators distinguish between three distinct terms that are often used interchangeably: side effects, adverse events, and adverse drug reactions (ADRs).
Understanding these distinctions helps you take control of your health, communicate clearly with your doctor or pharmacist, and contribute to medicine safety in South Africa.
Core Terminology: Side Effect vs. Adverse Event vs. Adverse Drug Reaction
| Term | Definition | Key Characteristic | Example |
| Side Effect | A secondary, usually predictable effect that occurs alongside the intended therapeutic effect at standard therapeutic doses. | Expected and documented; can be positive, neutral, or unwanted. | Mild drowsiness when taking an antihistamine for allergies. |
| Adverse Event (AE) | Any unfavourable or untoward medical occurrence in a patient taking a medicine, which does not necessarily have a proven causal connection to the drug. | Unfavourable outcome during treatment; causality is not yet proven. | Falling down stairs or developing a headache two days after starting a new blood pressure tablet. |
| Adverse Drug Reaction (ADR) | A harmful and unintended response to a medicine where a causal relationship between the drug and the reaction is suspected or established. | Harmful reaction with a reasonable suspicion that the drug caused it. | Developing a severe skin rash or swelling shortly after taking an antibiotic. |
Quick answer: when and how to report a suspected side effect
In South Africa, you should report any unexpected, bothersome, or harmful symptom that occurs while taking a medicine, supplement, or vaccine. You do not need to be certain that the product caused the symptom to submit a report—regulatory reporting is based on suspect connections.
Reporting can be done directly by patients or healthcare providers through official channels maintained by the South African Health Products Regulatory Authority (SAHPRA), including the Med Safety Mobile App or online Adverse Drug Reaction (ADR) portals.
What information to record
To ensure your report is effective and actionable, record four primary pillars of information:
- The Suspect Product: The exact brand name, active ingredient, batch number, expiry date, and daily dosage.
- The Symptom Details: What happened, how severe it was, and the exact date and time the symptom began.
- The Timeline: When you started taking the medicine relative to when the reaction occurred.
- Patient Profile: Age, gender, and any underlying conditions or concurrent medications being taken.
Where reporting fits into medicine safety
Submitting a report triggers a process called pharmacovigilance—the science of detecting, assessing, understanding, and preventing adverse effects. Individual reports are aggregated by SAHPRA to detect hidden safety patterns across the South African population, ensuring that medicines remain safe for public use over time.
Who can report a side effect or adverse drug reaction?
Anyone in South Africa can report a suspected side effect or adverse drug reaction. You do not need formal medical qualifications to submit a consumer safety report.
- Patients and Consumers: Anyone taking a medicine who experiences an unexpected symptom.
- Parents, Guardians, and Caregivers: Individuals managing medication for children, elderly relatives, or dependants.
- Healthcare Professionals: Doctors, pharmacists, nurses, dentists, and community health workers (who often file detailed clinical ADR reports).
- Pharmaceutical Manufacturers: Companies licensed to distribute health products in South Africa, who are legally mandated to report all safety concerns to SAHPRA.
If you feel uncertain about filing a report yourself, you can discuss your symptoms with a local pharmacist or clinic doctor, who can submit an official ADR report on your behalf.
What information to record
When filing as a consumer or caregiver, make sure to document:
- Your contact information (so regulatory safety officers can reach out for clarification if needed).
- Whether you spoke to a doctor or pharmacist about the symptom.
- Any medical interventions required (e.g., whether you needed an emergency room visit or extra medication).
Where reporting fits into medicine safety
Public participation expands safety monitoring beyond formal clinical trials. Clinical trials involve limited patient groups under controlled conditions, whereas real-world reporting captures how medicines behave across millions of diverse people with varying health profiles.
What information should you collect before reporting?
Before opening the reporting portal or app, gathering your details beforehand ensures your report is complete and avoids delays.
What information to record
Use this practical documentation checklist:
- Product Identifiers:
- Full product name (e.g., brand name or generic equivalent).
- Dosage form (e.g., tablet, syrup, injection, cream).
- Batch/Lot number and Expiry Date (found on the outer box or foil blister strip).
- Administration Details:
- Why you were taking the medicine (the medical condition being treated).
- How much you took and how often (e.g., 500 mg twice daily).
- Start date and stop date (if applicable).
- Reaction Details:
- Clear description of symptoms (e.g., dizziness, nausea, skin peeling).
- Date and time the symptoms started.
- Action taken (e.g., stopped the drug, reduced dose, took another medicine).
- Outcome (e.g., fully recovered, ongoing, resolving).
- Other Medical Context:
- Other prescription drugs, over-the-counter products, or traditional supplements taken at the same time.
- Pre-existing health conditions (e.g., asthma, kidney disease, diabetes).
Where reporting fits into medicine safety
High-quality, detailed reports allow pharmacovigilance specialists to evaluate probability scores (determining whether a drug likely caused a symptom or if it was a coincidence). Incomplete reports often cannot be fully analyzed.
How to report through SAHPRA, Med Safety or the ADR form
South Africa provides multiple official avenues to submit safety reports for medicines, vaccines, and complementary health products.

Where reporting fits into medicine safety
Once filed through the Med Safety App or online portal, reports enter SAHPRA’s National Pharmacovigilance Centre database. These reports are also shared globally with the World Health Organization (WHO) Collaborating Centre for International Drug Monitoring (Uppsala Monitoring Centre) to safeguard global public health.
What counts as a serious or unexpected side effect?
Side effects range from mild, self-limiting discomforts (such as transient dry mouth or mild stomach upset) to severe, life-threatening emergency events. Knowing when a symptom crosses into a “serious” threshold helps you seek the right level of care immediately.
Red-flag symptoms
Seek immediate emergency medical care if you or someone else experiences any of the following severe symptoms after taking medication:
- Breathing Distress: Shortness of breath, severe wheezing, or feeling like your airway is closing.
- Anaphylaxis / Swelling: Rapid swelling of the face, lips, tongue, mouth, or throat.
- Cardiovascular Distress: Chest pain, severe pressure, sudden rapid, irregular, or pounding heartbeat.
- Neurological Warning Signs: Fainting, sudden loss of consciousness, severe dizziness, confusion, or seizures/convulsions.
- Severe Skin Reactions: Blistering, peeling skin, mucosal sores, or a rapidly spreading red/purple rash (which could indicate conditions like Stevens-Johnson Syndrome).
- Mental Health Crisis: Sudden suicidal thoughts, severe depression, extreme agitation, or hallucinations.
- Severe Bleeding: Uncontrolled bleeding, black tarry stools, or vomiting blood.
- Signs of Overdose or Toxicity: Confusion, severe vomiting, extreme lethargy, or slurred speech.
- Rapidly Worsening Symptoms: Any symptom that escalates quickly in intensity or creates severe distress.
When to contact a doctor, pharmacist, or emergency service
- For Red-Flag Symptoms: Call emergency services immediately (such as 112 or 10177 in South Africa) or go directly to the nearest hospital casualty/emergency room. Do not attempt to drive yourself if you feel dizzy, confused, or short of breath.
- For Non-Urgent, Botherome Symptoms: Contact your prescribing doctor or community pharmacist. They can assess whether your dose needs adjustment, if a safer alternative exists, or if managing the symptom with additional care is appropriate.
- Stopping Medication: Do not stop taking essential long-term medication (such as blood pressure tablets, epilepsy medicine, or insulin) without professional guidance, as abrupt withdrawal can trigger severe complications.
What happens after a report is submitted?
Submitting an adverse drug reaction report is the vital first step in a larger national safety workflow.
What information to record
After submitting your report:
- Keep a record of your submission reference number (provided by the Med Safety App or portal).
- Maintain a personal medication log detailing any ongoing symptoms and any advice given by your doctor or pharmacist.
- Store a copy of the Patient Information Leaflet (PIL) from your medicine packaging for reference.
Where reporting fits into medicine safety
When SAHPRA receives a report, pharmacovigilance teams initiate a systematic review:
- Causality Assessment: Medical experts evaluate whether the drug was the probable cause of the event, considering underlying illnesses and other medications.
- Signal Detection: Regulators look for clusters of similar reports across the country. A single report may spark an investigation if a pattern emerges.
- Regulatory Action: If a safety risk is confirmed, SAHPRA may take public health actions, including:
- Updating the Patient Information Leaflet (PIL) or Professional Information (PI) with new warnings or side-effect frequencies.
- Issuing a national Drug Safety Alert or advisory to healthcare workers.
- Restricting the medicine’s approved uses, dosage recommendations, or target patient population.
- In extreme cases, suspending or withdrawing the product from the South African market.
Frequently Asked Questions
Can patients report directly?
Yes. Patients, consumers, and caregivers in South Africa can report suspected side effects directly to SAHPRA via the Med Safety Mobile App or the official online ADR reporting portal. You do not need authorization from a doctor to file a report.
Do I need proof the medicine caused it?
No, you do not need medical or scientific proof. Pharmacovigilance is designed to catch potential safety signals early. If you suspect a connection between a medication and an unexpected symptom, that is sufficient reason to submit a report.
Can my pharmacist help?
Yes. Community and hospital pharmacists in South Africa are trained in medicine safety and reporting procedures. They can help you review your symptoms, verify medicine details (such as batch numbers), file an ADR report on your behalf, and suggest safe next steps.
What details should I include?
At a minimum, ensure your report includes:
- An identifiable patient (age, sex).
- The name of the suspected medicine or product.
- A clear description of the reaction or symptom.
- The contact details of the person reporting.
What are the most important things to know about adverse event vs side effect?
- A side effect is a known, expected outcome that happens alongside the main treatment.
- An adverse event is any negative health event that occurs during treatment, whether or not the medicine caused it.
- An adverse drug reaction is a harmful reaction where a medicine is reasonably suspected to be the cause.
- Regardless of the term, any serious or concerning reaction should be evaluated by a healthcare professional and reported to SAHPRA.
