Humira (Adalimumab): Transforming Lives by Managing Autoimmune Disorders

Humira is an injectable prescription medication, also known by its generic name adalimumab. It is a monoclonal antibody that is typically used to treat various autoimmune diseases. Autoimmune disease is a type of disorder in which your body’s immune system mistakenly attacks healthy cells, tissues, and organs, which results in inflammation and other painful symptoms.

Humira belongs to the class of drugs called tumor necrosis factor (TNF) blockers that work to block the activity of TNF — a protein that causes inflammation in the body. 

Humira was first approved by the FDA in 2002 for the treatment of rheumatoid arthritis (RA). After its first approval, it has now been approved to treat various other autoimmune diseases since 2005. 

What Is Humira Used To Treat?

FDA has approved Humira for the following autoimmune conditions in adults and children: 

  • Rheumatoid arthritis (a disease causing joint inflammation)
  • Psoriatic arthritis (joint inflammation in addition to red, scaly skin patches)
  • Juvenile idiopathic arthritis (a condition characterized by inflammation in one or more joints)
  • Ankylosing spondylitis (a disease that causes inflammation in the joints and spine’s ligaments)
  • Crohn’s disease (a disease that causes gut inflammation) 
  • Ulcerative colitis (a disease that causes inflammation and ulcers in the gut lining)
  • Plaque psoriasis (a skin disease that causes red and scaly patches on the skin)
  • Hidradenitis suppurativa (a chronic skin condition characterized by lumps, scarring, and pus on the skin)
  • Uveitis (inflammation in the eye)

How Does Humira Work?

Humira contains an active drug called adalimumab, a monoclonal antibody designed to attach to a TNF protein. TNF proteins cause inflammation and are found at high levels in patients suffering from the aforementioned autoimmune diseases. 

Since Humira is a TNF blocker, it works to block the activity of TNF by attaching to it, thereby reducing the inflammation and other signs and symptoms caused by these diseases.
