The symptoms of flu are similar to a very bad cold. They include a high temperature, an aching body, tiredness and a headache.
Flu will usually get better in about a week if you rest, keep warm, drink plenty of fluids and take painkillers. Antibiotics do not help with flu.
You can help avoid flu by getting the flu vaccine every year.
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.
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.
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.
