Poisoning
Swallowed Poison
If someone has swallowed something poisonous, call 999 or 111 for advice, find out what and how much was taken, and do not make them vomit.
When to call 999. Call 999 if the person is drowsy, unresponsive, having a fit, struggling to breathe, or has swallowed a corrosive substance or a serious overdose. For advice when they seem well, call 111 or the poisons information service as directed.
What to do
- Try to find out what was swallowed, how much, and when — keep any packaging, bottle or plant to show the medical team.
- Call 999 for a seriously unwell person, or 111 for advice if they seem well.
- Do not try to make the person vomit.
- If they have swallowed a chemical and their lips or mouth are burned, give small sips of water or milk only if advised.
- If they become unresponsive, check breathing and place them in the recovery position; be ready to start CPR.
- Follow the specific advice given by 999 or 111, as it depends on the exact substance.
Avoid
What not to do
Never make the person vomit, as this can cause more harm, especially with corrosive chemicals or petroleum products. Do not give anything to eat or drink unless specifically advised, and do not assume a substance is harmless without checking.
Afterwards and while you wait
Keep any containers, labels or samples to help identify the poison and guide treatment. Stay with the person and monitor their breathing and responsiveness. Even if they seem well, follow the advice given, as some poisons act with a delay.
