Multiple sclerosis is treated on three fronts: slowing the disease itself with long-term medications, managing relapses when they happen, and controlling everyday symptoms like fatigue, pain, and stiffness. There is no cure, but the treatment landscape has expanded dramatically over the past two decades. More than 20 FDA-approved medications now exist to reduce relapses and delay disability progression, and the options range from daily pills to twice-yearly infusions.
Disease-Modifying Therapies
The backbone of MS treatment is a class of drugs called disease-modifying therapies, or DMTs. These don’t fix existing damage, but they reduce how often new attacks occur and slow the accumulation of disability over time. Starting a DMT early, ideally soon after diagnosis, gives you the best chance of preserving neurological function long-term.
DMTs come in three forms depending on how you take them:
- Oral medications are pills or capsules taken daily or on a set schedule. There are more than ten approved oral options, and they work through different mechanisms, from calming overactive immune cells to trapping certain white blood cells in lymph nodes so they can’t reach the brain and spinal cord.
- Injectable medications are self-administered shots given anywhere from every other day to once a month. The oldest DMTs fall into this category, including the interferon-based drugs that were the first MS treatments approved in the 1990s. Newer injectables use more targeted approaches, selectively depleting the immune cells most responsible for MS attacks.
- Infusion medications are given intravenously at a clinic or infusion center. Schedules vary widely. Some require infusions every few weeks, while others are given just twice a year or in short courses spread over two years. Infusions tend to be among the most potent DMTs and are often used for highly active or aggressive disease.
Choosing a DMT involves balancing effectiveness against side effects, convenience, and your specific type of MS. Someone with mild, infrequent relapses might start with a well-tolerated oral or injectable option. Someone with frequent relapses or signs of rapid progression on MRI may benefit from a higher-efficacy infusion therapy right away. Your neurologist will also consider factors like whether you’re planning a pregnancy, your comfort with needles, and whether you can get to an infusion center regularly.
Treatment for Progressive MS
Most DMTs were developed for relapsing-remitting MS, the form characterized by distinct flare-ups followed by periods of stability. Progressive MS, where disability worsens steadily without clear relapses, has historically been much harder to treat. For years there were no approved options for primary progressive MS at all.
That changed when ocrelizumab became the first therapy approved specifically for primary progressive MS. It’s given as an intravenous infusion twice a year and works by targeting a type of immune cell called B cells. For secondary progressive MS (which develops after an initial relapsing course), siponimod is approved as a daily oral tablet. These options don’t halt progression entirely, but they can meaningfully slow it.
How Relapses Are Treated
A relapse, sometimes called an exacerbation or flare-up, is a new or worsening neurological symptom that lasts at least 24 hours and isn’t caused by fever or infection. Not every relapse needs treatment. Mild sensory symptoms like temporary tingling may resolve on their own within weeks.
When a relapse causes significant disability, the standard treatment is a short course of high-dose corticosteroids, typically given intravenously over three to five days. The goal is to reduce inflammation quickly and shorten the relapse. Steroids don’t change the long-term course of the disease, but they can speed recovery from an acute attack. Side effects during the course can include insomnia, a metallic taste, mood changes, and elevated blood sugar.
For severe relapses that don’t respond to steroids, plasma exchange is sometimes used. This procedure filters the blood to remove the antibodies and inflammatory proteins attacking the nervous system. A typical course involves five sessions given daily or every other day.
Managing Everyday Symptoms
Even when DMTs are working well and relapses are infrequent, MS produces a range of day-to-day symptoms that need their own treatment strategies.
Fatigue
Fatigue affects roughly 80% of people with MS and is often the single most disabling symptom. It’s not ordinary tiredness. MS fatigue can hit suddenly and make even simple cognitive tasks feel overwhelming. Treatment usually combines medication with behavioral strategies like energy conservation techniques, where you learn to plan activities around your peak energy times, take strategic rest breaks, and simplify tasks. Dietary changes and structured exercise programs also play a role. Your provider will look for treatable contributors like poor sleep, depression, or medication side effects before adding new drugs.
Spasticity
Muscle stiffness and involuntary spasms are common, particularly in the legs. Mild spasticity can actually help with standing and transfers, but moderate to severe spasticity is painful and limits mobility. Treatment typically starts with stretching, physical therapy, and oral muscle relaxants like baclofen or dantrolene. For spasticity concentrated in specific muscles, botulinum toxin injections can provide targeted relief lasting several months.
A cannabis-based mouth spray containing equal parts THC and CBD (nabiximols) is approved in some countries for MS spasticity that hasn’t responded to other medications. A systematic review and meta-analysis in JAMA Network Open found cannabinoids to be safe regarding serious side effects, though their clinical benefit appears limited.
Pain
MS-related pain takes several forms. Nerve pain can feel like burning, stabbing, or electric shocks, and it’s commonly managed with anticonvulsants or certain antidepressants that calm overactive nerve signals. The “MS hug,” a tight banding sensation around the torso, is a specific type of nerve-generated discomfort that may respond to muscle relaxants, anticonvulsants, or topical numbing agents. Musculoskeletal pain from altered posture or gait is treated differently, usually through physical therapy and over-the-counter pain relievers.
Rehabilitation and Physical Therapy
Rehabilitation isn’t an add-on to MS treatment. It’s a core part of it. A physical therapist can address walking difficulty, poor balance, reduced coordination, and deconditioning through targeted programs that evolve as your needs change.
Common approaches include neuromuscular reeducation, which retrains your body to move smoothly and safely during everyday activities. Strengthening and flexibility exercises typically start simple and progress to functional movements like reaching overhead or picking objects up from the floor. For people who are sensitive to heat (a common MS trigger that temporarily worsens symptoms), aquatic therapy is particularly useful. Exercising in a temperature-controlled pool keeps your body cool while providing natural water resistance for both strength and cardiovascular training.
Occupational therapy focuses on the practical side: adapting your home and workspace, finding easier ways to manage daily tasks, and using assistive tools when needed. Speech therapy may help if MS affects swallowing or speech clarity. Cognitive rehabilitation targets the memory and processing-speed difficulties that many people with MS experience.
Diet and Lifestyle
No diet has been proven to change the underlying course of MS, but dietary patterns can meaningfully affect how you feel day to day. A 2023 systematic review and network meta-analysis published in Neurology compared eight dietary interventions across twelve randomized trials involving 608 participants. Three diets stood out for reducing fatigue: the Wahls protocol (a modified Paleolithic diet emphasizing vegetables, fruit, and grass-fed meat), a traditional low-fat diet (the approach pioneered by Dr. Roy Swank), and the Mediterranean diet. All three showed statistically significant fatigue reductions compared to a usual diet.
For overall quality of life, the Wahls and Mediterranean diets showed improvements in both physical and mental well-being. The researchers cautioned that the evidence quality was very low due to small sample sizes and study design limitations, so these results should be viewed as promising rather than definitive. Still, all three diets align with general principles of healthy eating: more vegetables, fruits, whole grains, and healthy fats, with less processed food and saturated fat.
Regular exercise is one of the most consistently supported lifestyle interventions for MS. It improves fatigue, mood, strength, and cardiovascular fitness without increasing relapse risk. Current guidance encourages at least 150 minutes of moderate activity per week when possible, adapted to your ability level. Vitamin D status is also worth monitoring, since low levels are linked to higher MS activity and supplementation is low-risk.
Smoking accelerates MS progression and reduces how well DMTs work. Quitting is one of the most impactful lifestyle changes you can make after diagnosis. Stress management, adequate sleep, and avoiding overheating round out the lifestyle factors that, taken together, can make a real difference in daily functioning alongside medical treatment.
