“D17 H” is a marking on a tablet, not a medicine name — and there is no product registered under it in South Africa. This page explains how pill imprints work, why identifying a loose tablet from its markings is unreliable, and how to find out safely what you actually have.
What is D17 H?
There is no match for “D17 H” on the South African Medicine Price Registry. It is not a brand name, an active ingredient, or a registered product.
What it almost certainly is, is an imprint code — the letters and numbers pressed or printed into a tablet or capsule. Manufacturers use these so that a loose tablet can be traced back to its product.
Three things about imprint codes are worth understanding, because they explain why this is harder than it looks.
They are not standardised internationally. In the United States, the FDA requires every solid oral prescription medicine to carry a unique imprint, and public databases let anyone look one up. South Africa has no equivalent public imprint database. Tablets sold here — many of them generics from India, South Africa or Europe — carry markings assigned by their manufacturer, with no central registry to search.
The same code can belong to different medicines. A code that identifies one product in an American database may be a completely different medicine on a tablet made elsewhere. Online pill identifiers are almost all US-based, and confidently returning an American answer for a South African tablet is exactly how people get this wrong.
Codes are commonly misread. “D17 H” could be D17H, DI7H, 017H, or a code split across a score line and read in the wrong order. A “1” and an “I”, a “0” and an “O”, a “5” and an “S” are easily confused, and a worn or half-dissolved tablet is worse still. Turn the tablet over — many carry markings on both faces, and half a code is far less useful than the whole thing.
What is D17 H commonly used for?
Because nothing is registered under this name or marking, there is no verified use to report — and guessing would be worse than saying nothing.
Here is how to find out what you have.
Take the tablet to a pharmacist. This is the fastest, safest and cheapest route, and it is free. Pharmacists identify unknown tablets routinely, have access to identification resources and wholesaler catalogues, and can often recognise a common generic on sight.
Take the packaging if you have any. A blister strip, box or dispensing label answers the question immediately. The active ingredient and strength on the label are the useful information — the brand name and the imprint are just packaging.
If it was dispensed to you, phone the pharmacy. They hold the dispensing record and can tell you exactly what was supplied. This also resolves the common situation where generic substitution means the tablets look nothing like last month’s.
Note where it came from. A tablet from a pharmacy, a clinic, a relative’s cupboard, or bought online are four very different situations, and the last two carry real risk.
Do not take a tablet you cannot identify. That is the whole of the advice. The risks are not theoretical: an unknown tablet may interact with something you already take, may be a medicine you react badly to, may be a dose intended for someone considerably larger or smaller, or may be counterfeit. Unidentified loose tablets are also a common route to accidental poisoning in children, so store or dispose of them accordingly.
Return unwanted or unidentified medicines to a pharmacy for disposal. Do not flush them or put them in household rubbish.
How D17 H fits into this medicine category
It does not, verifiably. But the categories below are worth understanding when you go to identify what you have:
| Type | How to recognise it | What it means |
|---|---|---|
| Registered medicine | SAHPRA registration number; a schedule (S0–S6); named active ingredients | Assessed for safety, quality and effect |
| Health supplement | No schedule; often “complementary medicine” wording | Much lighter regulation |
| Imported product | Foreign language or address; no SA registration number | May not be assessed here at all |
| Counterfeit | No traceable manufacturer; bought online; extravagant claims | Contents unknown and unreliable |
For registered products people commonly look up, see guides such as HP553 and K-Fenak OTC.

What to check before using D17 H
Before taking any tablet you cannot name:
- Identify the active ingredient, from packaging or from a pharmacist. Nothing else substitutes for this.
- Confirm it was prescribed for you, not for someone else. Sharing prescription medicines is genuinely risky — doses are set for a particular person, weight, kidney function and set of other medicines.
- Check it against everything else you take, which cannot be done without knowing what it is.
- Check the expiry date, once you know what it is.
- Be particularly careful if you take heart or blood pressure medicines, blood thinners, diabetes medicines, epilepsy medicines, antidepressants or antiretrovirals — these are the medicines where an unexpected interaction does the most harm.
- Be more cautious again if you are pregnant, breastfeeding, elderly, or considering giving it to a child.
If you found it loose in a bag or drawer and have no idea how long it has been there, the sensible answer is to dispose of it at a pharmacy rather than spend effort identifying it. A single tablet of unknown age and origin is not worth the risk.
Possible cautions and when to ask a pharmacist or doctor
Ask a pharmacist before taking it, not after. Identifying a tablet is routine work for them and takes minutes.
See a doctor if you have already taken it and feel unwell, if you are taking an unidentified tablet in place of something you were prescribed, or if you are unsure what any of your regular medicines are — a medicines review is worth asking for, and is particularly useful if you take several.
Get emergency help immediately for:
- A child who has swallowed an unidentified tablet, even if they seem completely well. Take the tablet and any packaging with you. Some medicines — including blood pressure tablets, diabetes tablets, iron and paracetamol — can seriously harm a small child at doses that are trivial for an adult, and several cause no symptoms for hours.
- Swelling of the face, lips or tongue, or difficulty breathing.
- A widespread rash, particularly with blistering, peeling or fever.
- Chest pain, palpitations, fainting or a seizure.
- Severe drowsiness or confusion.
- Severe abdominal pain, vomiting blood, or black tarry stools.
- Any suspected overdose, deliberate or accidental, even if the person appears fine. Take the packaging.
Take whatever you have with you — the tablet, the strip, the box. It is what allows anyone to work out what happened, and it is often the difference between quick treatment and guesswork.

Frequently asked questions
What is the D17 H pill used for? Nothing is registered under that name or marking in South Africa, so there is no verified answer. “D17 H” is an imprint code, not a medicine name. Take the tablet to a pharmacist.
Can I look up a pill imprint online? Cautiously. Almost all pill identifier databases are American, and South Africa has no public imprint register. The same code can mean different medicines in different countries.
How do I identify a loose tablet? Take it, and any packaging, to a pharmacist. If it was dispensed to you, phone the pharmacy — they hold the record.
My tablets look different from last month. Why? Usually generic substitution. The same active ingredient from a different manufacturer looks different and carries a different imprint. Your pharmacy can confirm it.
Is it safe to take a tablet I cannot identify? No. It may interact with your other medicines, be the wrong dose, or not be what you think.
What should I do with unidentified tablets? Return them to a pharmacy for disposal. Do not flush them or bin them, and keep them away from children until you do.
A child has swallowed an unknown tablet. What now? Go to an emergency department immediately, even if the child seems fine, and take the tablet and packaging. Several common medicines cause no symptoms for hours but are dangerous to a small child.
