The abstract, entitled "Drug exposure limitations of oral methotrexate (MTX) at doses ≥15mg may be overcome by using a subcutaneous MTX auto-injector in patients with rheumatoid arthritis (RA),"was among a select group of key abstracts awarded the distinction of a live, oral presentation.

OTREXUP is a single-dose auto-injector containing a prescription medicine, methotrexate. Methotrexate is used to:

  • treat certain adults with severe, active rheumatoid arthritis (RA), and children with active polyarticular juvenile idiopathic arthritis (pJIA), after treatment with other medicines including non-steroidal anti-inflammatory (NSAIDS) have been used and did not work well.

  • control the symptoms of severe, resistant, disabling psoriasis in adults when other types of treatment have been used and did not work well.

OTREXUP should not be used for the treatment of cancer.

OTREXUP should not be used for the treatment of children with psoriasis.

Methotrexate includes the following boxed warning:

OTREXUP can cause serious side effects that can lead to death, including:

  • Organ system toxicity. People who use methotrexate for the treatment of cancer, psoriasis, or rheumatoid arthritis, have an increased risk of death from organ toxicity. Types of organ toxicity can include: gastrointestinal, bone marrow, liver, immune system, nerve, lung, kidneys and skin.

    Your doctor will do blood tests and other types of tests before you take and while you are taking OTREXUP to check for signs and symptoms of organ toxicity.
