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)|
Important: Could it be coronavirus (COVID-19)?
If you have a high temperature, a new, continuous cough or a loss or change to your sense of smell or taste, it could be COVID-19.
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.
Call a pharmacy or contact them online before going in person. You can get medicines delivered or ask someone to collect them.
Urgent advice: Get advice from 111 now if:
- you're worried about your baby's or child's symptoms
- you're 65 or over
- you're pregnant
- you have a long-term medical condition – for example, diabetes or a heart, lung, kidney or neurological disease
- you have a weakened immune system – for example, because of chemotherapy or HIV
- your symptoms do not improve after 7 days
111 will tell you what to do. They can arrange a phone call from a nurse or doctor if you need one.
Go to 111.nhs.uk or call 111.
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

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.
Who can have the flu vaccine
The flu vaccine is given to people who:
- are 50 and over (including those who'll be 50 by 31 March 2021)
- have certain health conditions
- are pregnant
- are in a long-stay residential care
- receive a carer's allowance, or are the main carer for an older or disabled person who may be at risk if you get sick
- live with someone who's at high risk from coronavirus (on the NHS shielded patient list)
- frontline health or social care workers
People aged 50 and over
From 1 December, the NHS flu vaccination is available for everyone aged 50 and over. You can get vaccinated at your GP surgery or a pharmacy offering a flu vaccine service.
Where to get the flu vaccine
You can have the NHS flu vaccine at:
- your GP surgery
- a pharmacy offering the service
- your midwifery service if you're pregnant
If you have your flu vaccine at a pharmacy, you do not have to tell the GP. The pharmacist should tell them.
Due to high demand for the flu vaccine, there may be some delays getting a vaccination appointment. Your GP surgery or pharmacy should be able to tell you when more appointments are available.
