A virus causes the flu, so antibiotics are not effective. To recover, resting at home is typically all that is necessary if you are in good health.

If you experience symptoms that persist for a week or are susceptible to flu-related complications, it is advisable to seek medical attention from a doctor.

Your immune system will usually tackle viral infections such as the flu, so most people will just need to let it run its course.

Antibiotics will not work against the flu, as it is a viral infection. Antibiotics only work against bacterial infections.

If you are fit and healthy then you will usually just need to rest at home until you recover, which usually takes around a week. There are some self-care measures you can try whilst you’re getting better, which includes:

• Staying at home and getting plenty of rest and sleep

• Drinking lots of fluid to prevent dehydration

• Keeping yourself warm

• Taking over-the-counter painkillers to help with the symptoms

• Treating your cough with over-the-counter medication

In some cases, such as if you’re more at risk of complications because of the flu, a doctor may prescribe antiviral medicine.

These types of medications can make the symptoms less severe and speed up recovery time. They also have some side effects, which a doctor will discuss with you before recommending the treatment.

If you’re in an at risk group, such as being pregnant, having a long-term condition such as diabetes, heart disease or asthma or are over 65, you may wish to have the flu vaccine.

The vaccine introduces your immune system to the strains of flu thought to be most common, so your body can produce antibodies in advance, meaning it’s better equipped to tackle the virus if you become infected with it during the year.

The strains change rapidly, which is why it’s important to have an annual jab.
