“C25 green” is a description of a tablet — a marking and a colour — rather than the name of a medicine. No product is registered in South Africa under that name, and a tablet cannot be safely identified from its appearance alone. This page explains how to identify it properly, and why guessing is dangerous.
What is C25 Green?
A search of the South African Medicine Price Registry returns no product called C25 Green. That is expected, because it is not a product name.
What people are describing is a tablet bearing an imprint that looks like C25, in green. Manufacturers press codes into tablets so they can be identified — but those codes are not standardised across companies or countries. The same imprint can appear on completely different medicines made by different manufacturers, and a manufacturer can reuse a code.
South Africa has no comprehensive public pill-identification database, and the American ones widely found online do not reliably apply to South African products. A code matched against a US database may return a medicine that is not even sold here.
So this page will not tell you what your tablet is, and you should be sceptical of any website that claims to from a colour and a code.
A tablet’s appearance is not a safe identifier. Colour varies between generic manufacturers of the same medicine. Codes are reused. Coatings, shapes and sizes change between batches and brands. And counterfeit medicines are specifically made to look like something else.
What is C25 Green commonly used for?
The honest answer is that it cannot be established from the description, so what follows is how to establish it.
If you have the original packaging, read the active ingredients panel. That is the definitive answer, and it takes seconds.
If you do not have the packaging, take the tablet to a pharmacist. This is the single most useful step, it costs nothing, and pharmacists do it routinely. They have access to identification resources, they know the local market, and they can often narrow it down quickly.
If it came from a prescription, check the dispensing label and your clinic or pharmacy records. The pharmacy that dispensed it can tell you what they gave you.
What not to do:
- Do not take it because it resembles something you have taken before.
- Do not rely on an online pill identifier, particularly a foreign one.
- Do not take a tablet someone else gives you, even if they say it is the same as yours.
- Do not assume the colour means anything. It does not.
If a tablet cannot be identified, the safe answer is not to take it. An unidentified tablet cannot be checked against your other medicines, cannot be dosed correctly, and cannot be accounted for by a doctor if you become unwell.
Loose tablets are the underlying problem here. The reason people end up searching a colour and a code is almost always that medicines were decanted into a tin, a bag, a pill organiser without labels, or a container from something else. Keeping medicines in their original packaging prevents this entirely, and it is worth doing for exactly this reason.
How C25 Green fits into this medicine category
Since it cannot be identified, it cannot be placed. The general medicines category covers a wide range, and the cautions differ completely between groups:
| Group | Examples | Key caution |
|---|---|---|
| Simple analgesics | Paracetamol | Never take it twice — overdose damages the liver silently |
| Anti-inflammatories | Diclofenac (K-Fenak OTC) | Stomach bleeding, kidneys, asthma |
| Opioids | Codeine, tramadol | Breathing suppression; dependence |
| Sedatives | Benzodiazepines, sleeping tablets | Sedation; dangerous with alcohol or opioids |
| Cardiovascular | Blood pressure and heart medicines | Must not be started or stopped casually |
| Antibiotics | Amoxicillin, metronidazole | Only for bacterial infection; complete the course |
| Combination remedies | HP553 and similar | Several ingredients, several sets of cautions |
Until you know which row your tablet belongs to, none of that guidance can be applied — which is the whole argument for identifying it first. See the general medicines hub.
What to check before using C25 Green
- Identify it. Nothing else can be done responsibly until you have.
- Check the original packaging if it exists anywhere.
- Take it to a pharmacist if it does not.
- Check your prescription records or dispensing label.
- Do not take it if it cannot be identified.
- Check where it came from. A tablet from a pharmacy is a very different proposition from one bought informally, shipped from an unknown seller, or given by someone else.
- Consider disposal. If a tablet cannot be identified and is not needed, take it to a pharmacy for safe disposal rather than keeping it.
- Keep medicines in their original packaging in future, and label pill organisers.
Possible cautions and when to ask a pharmacist or doctor
Do not take an unidentified tablet. That applies to everyone, and especially if you take regular prescription medicines, are pregnant or breastfeeding, have a chronic condition, or are elderly.
Never give an unidentified tablet to a child, and keep loose tablets out of reach. A single tablet of several common adult medicines can seriously harm or kill a small child.
Get emergency help immediately if:
- A child has swallowed an unidentified tablet. Take whatever you have — the tablet, the container, anything — with you, and do not wait for symptoms.
- Anyone develops unusual drowsiness, difficulty being woken, or slow or shallow breathing after taking something.
- There is swelling of the face, lips or tongue, difficulty breathing, or a widespread rash.
- Anyone develops confusion, a racing or irregular heartbeat, seizures, or collapse.
Take the tablet or container with you if you seek help. Identifying what someone has taken changes what a clinician can do for them — and with an unknown tablet, treatment becomes guesswork at exactly the moment guesswork is most costly.
Ask a pharmacist whenever you have loose tablets you cannot account for, whenever a dispensed tablet looks different from last time — generic substitution is common and usually the explanation, but it should be confirmed rather than assumed — and whenever you are unsure whether two products contain the same ingredient.

Frequently asked questions
What is a green C25 tablet? It cannot be identified from a colour and an imprint. No product of that name is registered in South Africa, tablet codes are not standardised, and appearance is not a safe identifier.
Can’t I look it up online? Online pill identifiers are mostly built on American products and do not reliably apply to medicines sold in South Africa. A match may return something not even available here.
How do I find out what it is? Read the original packaging if you have it. If not, take the tablet to a pharmacist — they do this routinely and it costs nothing.
Is it safe to take if it looks like something I’ve had before? No. Colours and codes vary between manufacturers, and counterfeits are made to resemble genuine products.
What if my usual tablet looks different this time? That is usually generic substitution, which is normal and legal. Confirm with the pharmacy rather than assuming.
What should I do with tablets I can’t identify? Take them to a pharmacy for safe disposal. Do not keep unidentified tablets, and do not flush them.
What if a child swallows one? Get emergency help immediately, taking the tablet or container with you. Do not wait for symptoms.
How do I avoid this next time? Keep medicines in their original packaging, and label any pill organiser you use.
