In South Africa, medicines are classified into schedules, and where you can buy something depends on which schedule it falls into. That matters for safety, because the schedule reflects how much professional involvement a medicine is judged to need.
- Unscheduled and Schedule 0 products can be sold in general retail, including supermarkets and forecourts. Simple paracetamol and some antacids sit here.
- Schedule 1 and Schedule 2 medicines are pharmacy medicines. They do not need a prescription, but they are sold within a pharmacy, and Schedule 2 in particular is intended to involve a pharmacist rather than simply being handed over.
- Schedule 3 and above require a prescription.
The practical consequence: a product bought from a supermarket shelf comes with no screening at all, while the same visit to a pharmacy counter gives you someone who can check it against your other medicines. If you take anything regularly, that difference is worth using.
Common side effects of this pharmacy medicine or category
Being available without a prescription tells you a medicine is considered suitable for short-term self-treatment of a problem people can recognise themselves. It does not mean it has no meaningful effects. Anti-inflammatories can cause stomach bleeding, decongestants can raise blood pressure, sedating antihistamines impair driving, and codeine-containing products can cause dependence with regular use.
For the effects by category, see the OTC medicine side effects hub.
Interactions and duplicate-ingredient risks
Duplicate ingredients are the most common avoidable problem with pharmacy medicines. Paracetamol in particular appears in combination painkillers and in cold, flu and sinus remedies, so taking a plain paracetamol tablet alongside a flu remedy can double the dose without either pack looking like a painkiller.
The habit that prevents it: read the active ingredients panel on every product before combining anything, and treat brand names as unreliable guides to what is inside. See taking two medicines that both contain paracetamol.
General retail is where duplication most often happens, because nobody is checking what else is in your basket. See OTC medicine interactions.
Children, pregnancy, older adults and chronic medicine cautions
For these groups the schedule is a poor guide to suitability. A medicine on general sale can still be inappropriate in pregnancy, unsuitable for a young child, or risky for someone on blood thinners. Buy from a pharmacy and ask, rather than relying on availability as reassurance.

Warning signs and overdose concerns
Get emergency help for:
- Difficulty breathing, wheeze, or swelling of the face, lips or throat
- A rash that blisters or peels
- Vomiting blood, or black tarry stools
- Severe or sudden abdominal pain
- Chest pain, fainting, or a racing heartbeat
- Confusion or drowsiness that is out of character
Suspected overdose is an emergency even when the person feels well. This matters most with paracetamol, where serious liver damage can be underway for a day before any symptom appears, and treatment works best when started early. Go to an emergency unit and take the packaging. See paracetamol overdose symptoms.
