It's recommended that you have sotrovimab within 5 days of your symptoms starting.
Dosage
The dose of sotrovimab is 500mg. It's given through a drip, usually in your arm (infusion) over 30 minutes. You'll only need 1 dose.
Giving the medicine this way means it can be given at the right rate – not too fast and not too slow.
You will then need to be monitored during and after the infusion.
