Flu will often get better on its own, but it can make some people seriously ill. It's important to get the flu vaccine if you're advised to.
Check if you have flu
Flu symptoms come on very quickly and can include:
- a sudden high temperature of 38C or above
- an aching body
- feeling tired or exhausted
- a dry cough
- a sore throat
- a headache
- difficulty sleeping
- loss of appetite
- diarrhoea or tummy pain
- feeling sick and being sick
The symptoms are similar for children, but they can also get pain in their ear and appear less active.
Telling the difference between cold and flu
Cold and flu symptoms are similar, but flu tends to be more severe.
|Appears quickly within a few hours||Appears gradually|
|Affects more than just your nose and throat||Affects mainly your nose and throat|
|Makes you feel exhausted and too unwell to carry on as normal||Makes you feel unwell, but you're OK to carry on as normal (for example, go to work)|
How to treat flu yourself
To help you get better more quickly:
- rest and sleep
- keep warm
- take paracetamol or ibuprofen to lower your temperature and treat aches and pains
- drink plenty of water to avoid dehydration (your pee should be light yellow or clear)
A pharmacist can help with flu
A pharmacist can give treatment advice and recommend flu remedies.
Be careful not to use flu remedies if you're taking paracetamol and ibuprofen tablets as it's easy to take more than the recommended dose.

Other ways to get help
Get an urgent GP appointment
A GP may be able to treat you.
Ask your GP practice for an urgent appointment.
GPs do not recommend antibiotics for flu because they will not relieve your symptoms or speed up your recovery.
Immediate action required: Call 999 or go to A&E if you:
- develop sudden chest pain
- have difficulty breathing
- start coughing up blood
How to avoid spreading the flu
Flu is very infectious and easily spread to other people. You're more likely to give it to others in the first 5 days.
Flu is spread by germs from coughs and sneezes, which can live on hands and surfaces for 24 hours.
To reduce the risk of spreading flu:
- wash your hands often with warm water and soap
- use tissues to trap germs when you cough or sneeze
- bin used tissues as quickly as possible
- try to stay at home and avoid contact with other people if you have a high temperature or you do not feel well enough to do your normal activities

How to get the flu vaccine
The flu vaccine is a safe and effective vaccine. It's offered every year on the NHS to help protect people at risk of flu and its complications.
The best time to have the flu vaccine is in the autumn before flu starts spreading. But you can get the vaccine later.
