The main active ingredient of the Metoject® PEN is methotrexate. Methotrexate is a well known antirheumatic drug (DMARD), which helps to relieve the pain of joint inflammation and/or psoriasis and helps to prevent inflammation and damage. In these autoimmune diseases, the immune system is overly active and mistakenly attacks the body. Methotrexate can help to slow down the effects of an over-stimulated immune system, thus controlling the activity of the disease. Should you encounter any side effects whilst taking Metoject, please consult your doctor immediately.
