Frequently asked questions

Who should take COVID antivirals?

Mainly people at higher risk of severe illness (older age, weak immunity, certain conditions), started early. Most healthy people recover without them.

Why does Paxlovid interact with other medicines?

It contains ritonavir, which changes how the liver clears many drugs, so your doctor checks all your medicines before prescribing it.
