A concern about fentanyl may begin with an unidentified tablet or mixture. Packaging and appearance cannot confirm its contents. The person’s current condition matters more than finding the name; do not delay emergency help while investigating a substance.
If someone may be overdosing right now
Suspect an opioid overdose when the following signs appear.
- The person cannot be woken — shouting and shaking the shoulders produce no response;
- Breathing is slow, shallow, laboured or has stopped;
- Pupils are very small ("pinpoint");
- Skin, lips or fingernails are changing colour — turning blue, grey or very pale.
What to do, in order.
- Call 103 (ambulance) or 112 (unified emergency service). Say that the person is unconscious or not breathing normally and may have taken an opioid. Give the address clearly.
- Try to wake them. Call their name loudly and shake them by the shoulders.
- If they are not breathing normally, tell the dispatcher what you see and follow the instructions you are given on rescue breathing or chest compressions.
Why people take it without meaning to
Because so little fentanyl is needed, it is cheap to add to other substances — and it cannot be detected by looking. Drugs may contain deadly levels of fentanyl, and you would not be able to see it, taste it or smell it. Both situations occur: people knowingly consume fentanyl, and unknowingly consume it when it is mixed into or sold as other drugs, such as heroin, cocaine or counterfeit pills.
In practice this means that a person who buys "a sleeping pill" through a messenger, a "painkiller" without a prescription, or a stimulant powder may receive a synthetic opioid — and, having no tolerance to opioids, is at the highest risk of all.
Why an overdose comes so fast
Three factors combine.
Potency and uneven mixing. When an active dose is a fraction of a milligram, two portions that look identical can contain very different amounts. The person has no way to know which one they have.
No tolerance. People who use stimulants, or who take a counterfeit tablet, have no opioid tolerance. For them, a dose that a person with long-term use might survive is enough to stop breathing.
Dependence and the way out
Synthetic opioids can cause tolerance and dependence. Stopping may bring muscle aches, abdominal cramps, agitation, anxiety, nausea, vomiting, chills and diarrhoea. After a period without opioids, tolerance falls; returning to a previously familiar amount can cause a fatal overdose.
For family and friends
If someone close to you uses opioids, or takes pills or powders of unknown origin, two things are within your reach. Learn the signs of overdose in the block above and keep 103 and 112 saved in your phone. And keep the conversation open: a person who fears judgement hides their use, and an overdose that nobody sees cannot be stopped by anyone.

Questions
Can a tablet’s appearance identify it?
No. Appearance cannot reliably establish contents or potency.
Should I book a consultation first?
With life-threatening symptoms, seek emergency help first.
Are synthetic opioids all the same?
No. Potency and product contents may differ.
