Rebif® (interferon beta-1a)

 
 
Rebif® (interferon beta-1a)

Rebif ® is one of the leading treatments for multiple sclerosis (MS) in the United States. Rebif is proven to work on all three key measures of MS disease activity:
  • Progression of disability
  • Frequency of relapse
  • Activity and area of brain lesions on magnetic resonance imaging (MRI)*
Rebif has a safety profile supported by more than 16 years of worldwide patient and clinical trial experience. It also has many features designed for convenience, including
  • Simple starter pack with pre-measured, pre-filled doses
  • Rebiject II® auto-injector
  • 3-times weekly dosing
  • Room temperature storage up to 30 days, if refrigeration is unavailable.
*The exact relationship between MRI findings and the current or future clinical status of patients, including disability progression, is unknown.
 
Rebif®
Indication
Rebif® (interferon beta-1a) is used to treat relapsing forms of MS to decrease the frequency of relapses and delay the occurrence of some of the physical disability that is common in people with MS. 
Rebif is not approved for treatment of chronic progressive MS. 
Rebif is available in 22 mcg and 44 mcg prefilled, preassembled syringes and a titration pack by prescription only.
