(Interferon beta-1a)



Interferon beta-1a is an immunomodulator medicine which can enhance immune cell activities. Each pre-filled syringe of ReciGen® containing 44µg (12 Million IU / 0.5 ml) recombinant human interferon beta-1a for subcutaneous injection, produced under EU GMP license.

Important safety information

  • Increased ALT, AST and bilirubin have been reported. Obtain liver function tests at 1, 3, and 6 months’ post therapy initiation and periodically thereafter. Treatment should be suspended immediately if jaundice or symptoms of hepatic dysfunction occur. Consider dose reductions or temporary discontinuation if ALT >5 times ULN. Use with caution in patients with hepatic impairment or in those who abuse alcohol.
  • Pancytopenia (rare), leukopenia, and thrombocytopenia have been reported. Monitor blood counts at 1, 3, and 6 months’ post therapy initiation and periodically thereafter. Events may recur with rechallenge.
  • Flu-like symptoms have a high incidence while taking interferon beta-1a. Use of analgesics and/or antipyretics on treatment days may be helpful.
  • Interferons have been associated with psychiatric adverse events (psychosis, depression, suicidal behavior/ideation) in patients with and without previous psychiatric symptoms; use with caution in patients with depression.
  • Some patients have had seizures while taking interferon, including patients who have never had seizures. Use with caution in patients with a history of seizure disorder.
  • Allergic reactions, including anaphylaxis, have been reported. Some reactions may occur after prolonged use. Discontinue therapy if anaphylaxis or other allergic reactions occur.
  • Some people who take interferon beta-1a may get an infection. Urinary and upper respiratory tract infections are more common.
  • Thyroid abnormalities may develop with use; may worsen pre-existing thyroid conditions. Monitor thyroid function tests every 6 months or as clinically necessary.
  • In a scientific statement from the American Heart Association, interferon has been determined to be an agent that may either cause reversible direct myocardial toxicity or exacerbate underlying myocardial dysfunction (AHA [Page 2016]).
  • Autoimmune disorders including idiopathic thrombocytopenia, hyper- and hypothyroidism and rarely autoimmune hepatitis have been reported. Consider discontinuation of treatment if patient develops a new autoimmune disorder.
  • Severe injection site reactions have occurred, including pain, erythema, edema, cellulitis, abscess, and necrosis. 
  • Cases of thrombotic microangiopathy manifesting as thrombotic thrombocytopenic purpura (TTP) or hemolytic uremic syndrome (HUS) (some fatal) have been reported.
  • formulations that contain albumin are contraindicated in albumin-sensitive patients.
