Treatment has come a long way.
Gone are the days when multiple sclerosis destined patients to a life in a wheelchair. Treatments for MS have advanced, often dramatically changing the course of the condition and improving lives for MS patients.
What is relapsing-remitting multiple sclerosis?
Patients with relapsing-remitting multiple sclerosis experience periods of attacks on the central nervous system. These attacks are called relapses, which is a period of new or worsened symptoms. Relapses may be followed by a period of remission, when MS symptoms stop or subside.
RRMS is the most common type of multiple sclerosis. It affects around 85 percent of patients. (Learn more about what relapsing-remitting multiple sclerosis is here.)
What are medications to treat relapsing-remitting MS?
After a diagnosis of RRMS, patients meet with their doctors to develop a treatment plan. “We do blood testing to see which treatment options might be best and safest for the patient,” says Michelle Fabian, MD, a Neurologist for The Mount Sinai Hospital in New York City. “We take a lot of factors into account.”
The goal of treatment is to prevent MS relapses and keep symptoms from worsening. There are two main kinds of medications for relapsing-remitting MS:
- Immunomodulators make the immune system work more gently. If effective, immunomodulators would prevent attacks from damaging the myelin and causing relapses.
- Immunosuppressants take away parts of the immune system. “An immunosuppressant will typically carry a higher risk,” says Dr. Fabian, “because that patient will not be able to fight an infection to the same degree as somebody who didn’t have that immunosuppressant.”
These can come in different forms:
- Injectable medications are an older form of treatment and less effective than newer options. Patients inject these themselves using a pen-like device against the skin and pressing a button, which releases the injection.
- Oral medications, which are pills that the patient takes once or twice a day. Since the introduction of pills for MS, most patients choose this option over injectables, according to Dr. Fabian.
- Infusion medications are delivered through an IV every four weeks (at least) to a year (at most). Infusion medications are potentially the most powerful and effective form of treatment for MS, according to Dr. Fabian. However, infusion medications for relapsing-remitting MS also come with more risks.
How do you choose the right multiple sclerosis treatment?
The right MS treatment option depends on the patient and the specific symptoms they experience. Some of the factors affecting this decision include:
- Relapse history of the patient
- Results from MRIs or other exams
Doctors typically only prescribe the high-powered, yet riskier, medications for those with more severe relapses and neurological damage.
Of course, the patient’s input matters here, too. “We have some patients who are very worried about risk,” says Dr. Fabian. “They would rather start on one of the safer but lower-power treatments, and if they had new symptoms or a new lesion, they would consider maybe going to a higher-risk drug.”
No matter what you choose, treatment for MS can prevent further lesions, symptoms, and relapses. Learn more about how new medications have changed the outlook for patients here.

00:00:00,000 --> 00:00:03,915
00:00:03,915 --> 00:00:06,798
A lot of people do know
people in their community,
00:00:06,798 --> 00:00:09,860
family members who have MS
before it was treatable.
00:00:09,860 --> 00:00:12,730
a lot of people think of that as MS.
00:00:12,730 --> 00:00:16,540
And of course, that is MS,
but that is untreated MS.
00:00:16,540 --> 00:00:21,290
Now that we have treatments, we think
the condition has significantly changed.
00:00:21,290 --> 00:00:25,744
00:00:25,744 --> 00:00:29,800
After the diagnosis of relapsing-remitting
MS is made, patient comes in and
00:00:29,800 --> 00:00:34,410
talks to the doctor about the treatment
options, of which we have many.
00:00:34,410 --> 00:00:39,140
We do blood testing to see which treatment
options might be best and safest for
00:00:39,140 --> 00:00:43,040
the patient, and
we take a lot of factors into account.
00:00:43,040 --> 00:00:47,240
Some of our medications
are called immunomodulators.
00:00:47,240 --> 00:00:51,550
They work a little more gently,
just trying to change the immune system
00:00:51,550 --> 00:00:55,580
to make it a little gentler and
to stop those attacks from recurring.
00:00:55,580 --> 00:00:57,550
And we have a few of those.
00:00:57,550 --> 00:00:59,790
We also have immunosuppressants.
00:00:59,790 --> 00:01:04,210
Those are medications that actually
take away parts of the immune system.
00:01:04,210 --> 00:01:08,320
They target different cell types and
actually remove them, so
00:01:08,320 --> 00:01:10,760
that the cell can't form a new lesion.
00:01:10,760 --> 00:01:14,070
An immunosuppressant will
typically carry a higher risk
00:01:14,070 --> 00:01:18,200
because that patient would not
be able to fight an infection
00:01:18,200 --> 00:01:22,650
to the same degree as somebody who
didn't have that immunosuppressant.
00:01:22,650 --> 00:01:24,210
So we have the older medications.
00:01:24,210 --> 00:01:25,550
Those are injections.
00:01:25,550 --> 00:01:29,045
Those are small needles and
they're usually like a pen type of needle,
00:01:29,045 --> 00:01:32,610
where a patient puts it on their skin and
just kind of presses the button.
00:01:32,610 --> 00:01:37,480
They work maybe the least
well of our medications.
00:01:37,480 --> 00:01:42,510
We have pills and we have multiple
pills that are out now which is great.
00:01:42,510 --> 00:01:45,312
So those medications are different,
each one of them.
00:01:45,312 --> 00:01:48,700
Two are once a day and
then one is twice a day.
00:01:48,700 --> 00:01:51,010
We also have infusion medications.
00:01:51,010 --> 00:01:51,880
Those are IV.
00:01:52,880 --> 00:01:55,100
And we have multiple different ones.
00:01:55,100 --> 00:02:00,620
And so each medication has its own time
of how long it takes to get the IV,
00:02:00,620 --> 00:02:02,090
how often you get it.
00:02:02,090 --> 00:02:07,230
And those are the most powerful,
maybe the best of our treatments, but
00:02:07,230 --> 00:02:09,170
also carry the most risk.
00:02:09,170 --> 00:02:13,999
So when we look at a patient and we think
about which medication is right for them,
00:02:13,999 --> 00:02:18,543
we look at their history, their relapse
history, the symptoms they have,
00:02:18,543 --> 00:02:20,476
how their exam looks right now.
00:02:20,476 --> 00:02:25,300
If somebody's had very mild relapses,
they look neurologically normal.
00:02:25,300 --> 00:02:29,020
We might think of one of
the milder treatments for them.
00:02:30,020 --> 00:02:33,030
If a patient has had more severe relapses,
00:02:33,030 --> 00:02:37,340
we might think of one of
the more higher power treatments.
00:02:37,340 --> 00:02:40,910
We also think about the patient and
of course talk to the patient and
00:02:40,910 --> 00:02:42,480
get their take on it.
00:02:42,480 --> 00:02:45,160
We have some patients who
are very worried about risk.
00:02:45,160 --> 00:02:50,990
They would rather start on one of
the safer but lower power treatments.
00:02:50,990 --> 00:02:52,578
And if they had new symptoms or
00:02:52,578 --> 00:02:57,900
a new lesion, then they would consider
maybe going to a higher risk drug.
00:02:57,900 --> 00:03:01,680
There are some patients that don't mind
injecting themselves with the medication.
00:03:01,680 --> 00:03:06,200
And before we had the orals,
that's what we had, and so
00:03:06,200 --> 00:03:08,030
many patients were doing that.
00:03:08,030 --> 00:03:10,660
Most patients now would
rather not do that.
00:03:10,660 --> 00:03:15,030
The injectables do tend to have the lowest
risk, but most people, I would say,
00:03:15,030 --> 00:03:18,700
would prefer an oral, or maybe even an IV.
00:03:18,700 --> 00:03:20,090
Because then you get it.
00:03:20,090 --> 00:03:22,779
And then you don't have to think
about it until the next time you go.
