What is Enbrel?

Enbrel is an injectible medication used to treat several forms of arthritis and psoriasis. It was first approved in 1998. According to the manufacturer’s website, it is currently FDA approved to treat these conditions:

  • Moderate to Severe Rheumatoid Arthritis (RA)
  • Active Polyarticular Juvenile Idiopathic Arthritis,
  • Psoriatic Arthritis,
  • Ankylosing Spondylitis,
  • Moderate to Severe Plaque Psoriasis.

How Effective is Enbrel? 66% of people with moderate to severe RA saw less pain and stiffness with Enbrel at three months. Over half (55%) of people who were still taking Enbrel five years after starting therapy had no additional joint damage.

How Safe is Enbrel? Generally it is safe, in one six month study 25% (39 of 152)  of patients with RA taking placebo and 14% of patients (50 of 349) taking Enbrel developed infections, including bacterial, viral and fungal infections. The most frequent infections were upper respiratory tract infections, sinusitis and influenza. Further information may be found here.
