Frequently asked questions
How are biologics different from tablets?
They are large, targeted proteins given by injection/infusion that block specific immune signals, used when standard medicines have not worked.
Why is TB screening needed first?
Biologics can reactivate hidden (latent) TB or hepatitis, so these are checked and treated before starting.
