Humira reduces joint inflammation and damage from rheumatoid arthritis by blocking a chemical activator of inflammation called tumor necrosis factor.
Humira is an injection. It is given by self-injection under the skin once every two weeks. Patients can learn to give their own injections or receive them from a family member or caregiver who has had proper instruction. Preloaded syringes are available as self-injectable “click-pens.”
