Multiple sclerosis – Treatment

There is no cure for multiple sclerosis. Treatment typically focuses on speeding recovery from attacks, slowing the progression of the disease and managing MS symptoms. Some people have such mild symptoms that no treatment is necessary.

Treatments for MS attacks

• Corticosteroids, such as oral prednisone and intravenous methylprednisolone, are prescribed to reduce nerve inflammation. Side effects may include insomnia, increased blood pressure, mood swings and fluid retention.
• Plasma exchange (plasmapheresis). The liquid portion of part of your blood (plasma) is removed and separated from your blood cells. The blood cells are then mixed with a protein solution (albumin) and put back into your body. Plasma exchange may be used if your symptoms are new, severe and haven’t responded to steroids.

Treatments to modify progression

For primary-progressive MS, ocrelizumab (Ocrevus) is the only FDA-approved disease-modifying therapy (DMT). Those who receive this treatment are slightly less likely to progress than those who are untreated.

For relapsing-remitting MS, several disease-modifying therapies are available.

Much of the immune response associated with MS occurs in the early stages of the disease. Aggressive treatment with these medications as early as possible can lower the relapse rate and slow the formation of new lesions.

Many of the disease-modifying therapies used to treat MS carry significant health risks. Selecting the right therapy for you will depend on careful consideration of many factors, including duration and severity of disease, effectiveness of previous MS treatments, other health issues, cost, and child-bearing status.

Treatment options for relapsing-remitting MS include injectable medications, including:

• Beta interferons. These medications are among the most commonly prescribed medications to treat MS. They are injected under the skin or into muscle and can reduce the frequency and severity of relapses. Side effects of beta interferons may include flu-like symptoms and injection-site reactions. You’ll need blood tests to monitor your liver enzymes because liver damage is a possible side effect of interferon use. People taking interferons may develop neutralizing antibodies that can reduce drug effectiveness.
• Glatiramer acetate (Copaxone, Glatopa). This medication may help block your immune system’s attack on myelin and must be injected beneath the skin. Side effects may include skin irritation at the injection site.

Oral treatments include:

• Fingolimod (Gilenya). This once-daily oral medication reduces relapse rate. You’ll need to have your heart rate monitored for six hours after the first dose because your heartbeat may be slowed. Other side effects include rare serious infections, headaches, high blood pressure and blurred vision.
• Dimethyl fumarate (Tecfidera). This twice-daily oral medication can reduce relapses. Side effects may include flushing, diarrhea, nausea and lowered white blood cell count.
• Teriflunomide (Aubagio). This once-daily oral medication can reduce relapse rate. Teriflunomide can cause liver damage, hair loss and other side effects. It is harmful to a developing fetus and should not be used by women who may become pregnant and they — or their male partner — are not using appropriate contraception.
• Siponimod (Mayzent). Research shows that this once-daily oral medication can reduce relapse rate and help slow progression of MS. It’s also approved for secondary-progressive MS. Possible side effects include viral infections, liver problems and low white blood cell count. Other possible side effects include changes in heart rate, headaches and vision problems. Siponimod is harmful to a developing fetus, so women who may become pregnant should use contraception when taking this medication and for 10 days after stopping the medication.

Infusion treatments include:

• Ocrelizumab (Ocrevus). This humanized immunoglobulin antibody medication is the only DMT approved by the FDA to treat both the relapse-remitting and primary-progressive forms of MS. Clinical trials showed it reduced relapse rate in relapsing disease and slowed worsening of disability in both forms of the disease. Ocrevus is given via an intravenous infusion by a medical professional. Infusion-related side effects may include irritation at the injection site, low blood pressure, a fever and nausea, among others. Ocrevus may also increase the risk of some types of cancer, particularly breast cancer.
• Natalizumab (Tysabri). This medication is designed to block the movement of potentially damaging immune cells from your bloodstream to your brain and spinal cord. It may be considered a first line treatment for some people with severe MS or as a second line treatment in others. This medication increases the risk of a potentially serious viral infection of the brain called progressive multifocal leukoencephalopathy (PML) in people who are positive for antibodies to the causative agent of PML JC virus. People who don’t have the antibodies have almost no risk of PML.
• Alemtuzumab (Campath, Lemtrada). This drug helps reduce relapses of MS by targeting a protein on the surface of immune cells and depleting white blood cells. This effect can limit potential nerve damage caused by the white blood cells. But it also increases the risk of infections and autoimmune disorders, including a high risk of thyroid autoimmune diseases and rare immune mediated kidney disease. Treatment with alemtuzumab involves five consecutive days of drug infusions followed by another three days of infusions a year later. Infusion reactions are common with alemtuzumab. The drug is only available from registered providers, and people treated with the drug must be registered in a special drug safety monitoring program.
• Mitoxantrone. This immunosuppressant drug can be harmful to the heart and is associated with development of blood cancers. As a result, its use in treating MS is extremely limited. Mitoxantrone is only rarely used to treat severe, advanced MS.

Treatments for MS signs and symptoms

• Physical therapy. A physical or occupational therapist can teach you stretching and strengthening exercises and show you how to use devices to make it easier to perform daily tasks. Physical therapy along with the use of a mobility aid when necessary can also help manage leg weakness and other gait problems often associated with MS.
• Muscle relaxants. You may experience painful or uncontrollable muscle stiffness or spasms, particularly in your legs. Muscle relaxants such as baclofen (Lioresal) and tizanidine (Zanaflex) may help.
• Medications to reduce fatigue. Amantadine (Gocovri, Oxmolex), modafinil (Provigil) and methylphenidate (Ritalin) may be helpful in reducing MS-related fatigue. Some drugs used to treat depression, including selective serotonin reuptake inhibitors, may be recommended.
• Medication to increase walking speed. Dalfampridine (Ampyra) may help to slightly increase walking speed in some people. People with a history of seizures or kidney dysfunction should not take this medication.
• Other medications. Medications also may be prescribed for depression, pain, sexual dysfunction, insomnia, and bladder or bowel control problems that are associated with MS.
