Molnupiravir is an antiviral medicine that works by stopping the virus that causes COVID-19 from growing and spreading.
It's used to treat early COVID-19 infection and help to prevent more severe symptoms.
Molnupiravir is only available on prescription and comes as capsules. You'll need to start taking the capsules as soon as possible after you have tested positive for COVID-19 and within 5 days of your symptoms starting.
You will only be eligible to have the medicine if you're in the highest risk group.
If you are eligible for COVID-19 treatment you will usually be offered Paxlovid or remdesivir, before molnupiravir.
If you have tested positive for COVID-19 and are eligible, call your GP, NHS 111 or hospital specialist as soon as possible. This is so they can consider referring you for an assessment for COVID-19 treatment.
