About remdesivir

Remdesivir is an antiviral medicine that works by stopping the virus that causes COVID-19 from growing and spreading in the body.

It's used to treat early COVID-19 infection and help to prevent more severe symptoms.

You will be given remdesivir through a drip, usually in your arm (infusion).

You'll need to have the treatment as soon as possible after you have tested positive for COVID-19 and within 7 days of your symptoms starting.

You'll be given remdesivir in a hospital or at a local centre.

You will only be eligible to have the medicine if you are in the highest risk group.

If you test positive for COVID-19, and are eligible, call your GP surgery, NHS 111 or your hospital specialist as soon as possible. This is so they can consider referring you for an assessment for COVID-19 treatment.
