01

Urgent but not immediately life-threatening

Use NHS 111 online or call 111 if you think you need medical help now but it is not a 999 emergency. NHS 111 can direct you to urgent physical or mental-health care.[NHS]

02

Urgent mental-health help

If you need urgent help for your mental health, NHS guidance advises using 111 and selecting the mental-health option or asking for an urgent GP appointment. If there is immediate danger to life, call 999.

03

Alcohol withdrawal

If you are dependent on alcohol, stopping suddenly can be dangerous. Get medical advice before trying to stop if you develop withdrawal symptoms such as anxiety, sweating, tremor, nausea or vomiting. Severe symptoms such as marked shaking, confusion, hallucinations or a seizure need emergency assessment.

04

If you are with someone who may have overdosed

Call 999. Tell the call handler what you know about the substance and amount. Follow their instructions. If opioid overdose is suspected and naloxone is available, use it according to its instructions while emergency help is on the way.
