Consider switching multiple sclerosis treatments
Consider switching multiple sclerosis treatments
Are you tired of taking daily injections for your MS? Are you concerned about brain lesions? See below for common reasons some people consider switching multiple sclerosis treatments and learn more about your options.
- Injection-site reactions cause you to skip shots.
- The number of weekly injections required interferes with your lifestyle.
- You want an MS treatment that both slows physical disability progression and reduces the number of flare-ups (relapses).
- You want to be active and able longer, with a treatment that slows down the progression of physical disability.
- You want a multiple sclerosis medication that is effective against brain lesions and brain atrophy.
- You’re concerned about neutralizing antibodies and their possible effect on your current multiple sclerosis medication.
Injection-site reactions cause you to skip
shots.
All multiple sclerosis medications that treat the underlying disease are given
by injection. These injections can lead to unsightly injection-site reactions
and even infection. In clinical studies, only 3 out of 100 people taking AVONEX
reported injection-site reactions often seen with other MS therapies.
The number of weekly injections required interferes with your
lifestyle.
AVONEX is the only once-a-week MS therapy. So AVONEX is the only one to free
you from worrying about your MS injections every day or even every other
day.

With training, you or your care partner can self-administer AVONEX at home. And with the AVONEX prefilled syringe, preparing and administering the injection is simple and convenient.
You want a treatment that both
slows progression of physical disability and reduces the number of flare-ups
(relapses).
AVONEX slows down physical disability, to help you stay active and able, AND
reduces the number of flare-ups—so you can go on with your daily life.
Your healthcare provider or nurse may be using the expanded disability scale
to measure how you are doing. The scale measures disability progression by
looking at areas such as:
- Brain function
- Sensory and motor symptoms
- Coordination skills
- Bowel and bladder function
- Visual symptoms
AVONEX slowed down disability
by 37% in a 2-year study. In a 5-year study, nearly 9 out of 10 patients taking
AVONEX were still active and able.

AVONEX has been proven effective in clinical trials lasting up to 3 years.
AVONEX also reduces the number of flare-ups (also called relapses or attacks). In people who have only had 1 flare-up, AVONEX cuts the risk of a second flare-up almost in half (44%). In people with multiple (9 or more) brain lesions, AVONEX reduces the risk of a second flare-up by 66%.

* People
with MS in whom effectiveness has been demonstrated include people who have
experienced a first attack and have lesions consistent with MS on their
MRI.
Please see the
Patient Medication Guide.
You want a multiple
sclerosis medication that works against brain lesions and brain
atrophy.
Your healthcare provider may be measuring the size and number of brain lesions
on your MRI. These lesions are signs of how the disease has advanced. Brain
lesions may affect your ability to perform everyday tasks.
AVONEX slows down the formation of harmful brain lesions and reduces the size of lesions by 91%.
AVONEX can also reduce the rate of brain atrophy (brain shrinkage).by more than half. In the second year of a clinical trial, people taking AVONEX had 55% less brain shrinkage than those not on therapy.

Brain atrophy may affect your ability to stay active.
Your healthcare provider may be measuring the size and number of brain lesions on your MRI. These lesions are signs of how the disease has advanced. Brain lesions may affect your ability to perform everyday tasks.
You’re concerned about
neutralizing antibodies and their possible effect on your current multiple
sclerosis medication.
Though studies suggest there is an impact, the exact relationship between
MRI findings and your overall health is not fully understood.
Some people with MS can develop a resistance to their treatment over time.
This can happen because their bodies make cells called neutralizing antibodies
that neutralize (or inactivate) their MS treatment. Although the significance
of neutralizing antibodies is not fully understood, it is thought that they can
make your MS treatment lose its effectiveness over time.
AVONEX has a low incidence of these neutralizing antibodies, which are
thought to decrease a drug’s effectiveness over time.
In recent studies, 5% of people taking AVONEX had detectable levels of
neutralizing antibodies after 1 year.
In a different study, people taking AVONEX showed a very low risk (2%) of
developing neutralizing antibodies after 18 months. In contrast, 15% of people
taking Rebif® (interferon beta-1a) in that study and 31% of people taking
Betaseron® (interferon beta-1b) showed detectable levels of these
antibodies.

The rate of neutralizing anti-bodies with Betaseron ranges from 16.5% to 45% depending on the clinical trial.
A group of leading MS experts agreed that each treatment's potential for leading to the development of neutralizing antibodies should be considered in determining whether or not to recommend a treatment.
Although the significance of neutralizing antibodies is not fully understood, it is thought that they can make your MS treatment lose its effectiveness over time.
