Interferons, adalimumab and etanercept are given by injection. A medical professional will show you how to prepare the needle and syringe. You will be taught how to inject yourself.
A family member or other caregiver can learn the injection technique as well. He or she can give you the injection if you feel too weak or ill to give it to yourself.
Usually, the IL-2 and monoclonal antibodies are given intravenously.
