Amjevita is a prescription medication approved by the Food and Drug Administration (FDA) to reduce signs and symptoms, inhibit disease progression, and improve function in adults with moderately to severely active rheumatoid arthritis. Amjevita may be referred to by its drug name, Adalimumab-atto. Amjevita is a biosimilar of Humira. As defined by the FDA, a biosimilar is a biological product that is approved based on a showing that it is highly similar to an already-approved biological product.

Amjevita is an immunomodulator, or in other words, a drug that modulates the immune system. It is considered a biologic disease-modifying antirheumatic drug (DMARD). Amjevita is a genetically engineered antibody, or protein used by the immune system to identify and neutralize substances. Amjevita is believed to work by inhibiting tumor necrosis factor alpha (TNF-α), a chemical messenger involved in autoimmune attacks.

How do I take it?
Amjevita is administered as a subcutaneous injection every week or every other week.

Amjevita is available as single-use, prefilled auto-injector or syringe.
