How does Enbrel treat RA?

ANSWER

Etanercept (Enbrel) eases joint inflammation and damage from rheumatoid arthritis by blocking a chemical activator of inflammation called tumor necrosis factor (TNF).

Enbrel is delivered by self-injection under the skin once or twice a week. You can learn to give their own injections or get them from a family member or caregiver who has had proper instruction. Pre-loaded syringes are available as self-injectable “click-pens.”

In addition to pain at the injection site, Enbrel's most common side effects are infection, including upper respiratory infections like a cold, diarrhea, rash, and itchy skin.
