For swallowed poison:

- Ask what poison is involved and take a photo of the bottle or packet.
For inhaled poison:

- Loosen tightened clothing.
For skin exposure to poison:
- Don’t touch the chemical or exposed area yourself. Use protective clothing such as gloves and goggles.

- Flood the skin with cool running water.
- Gently wash with soap and water.
For eye exposure to poison:

How is poisoning diagnosed?
A doctor will need to work out how harmful the poison is and manage it accordingly.
They may ask you:
- what substance you were exposed to, and how much (you may need to refer to the bottle or packet)
- when and how you were exposed (mouth, airways or skin contact)
- what symptoms you have
They may do blood tests to confirm or rule out common substances such as paracetamol.
How is poisoning treated?
Being poisoned can be life threatening.
If you are admitted to hospital, staff will try to remove or treat the poison. Possible treatments include:
- activated charcoal
- antidotes — to stop the poison from working or reverse its effects
- anti-epileptic medicine — if you are having seizures
- sedatives — if you are agitated
In cases where the poisoning was intentional (such as a drug overdose), you will be referred to mental health services for extra support.
