BETASERON® (interferon beta-1b) is a prescription medicine used to treat relapsing forms of multiple sclerosis (MS), to include clinically isolated syndrome, relapsing-remitting disease, and active secondary progressive disease, in adults.
Most people with multiple sclerosis (MS) have a type called relapsing-remitting MS (RRMS). RRMS is a disease that causes neurologic symptoms from inflammation in the central nervous system (CNS).
This inflammation happens when your body’s immune system mistakenly attacks the CNS and damages the protective coating around your nerves, which is called myelin. Referred to as demyelination, this is caused by an abnormal immune process that happens when T cells attack the myelin that surrounds the nerve fibers. This damage prevents your nerves from sending signals to your brain, spinal cord, and other parts of your body the way they should.
In RRMS, symptoms worsen (relapse) and then decrease or sometimes disappear (remission). Remissions can last from months to years.
The symptoms of RRMS are variable and unpredictable. No two people have exactly the same symptoms, and each person’s symptoms can change or fluctuate over time.
Some of the more common symptoms of RRMS include:
To make a diagnosis of RRMS, your doctor—most likely a neurologist—may perform:
Occasionally, your doctor may perform a spinal tap to look at the fluid that surrounds your brain and spinal cord.
