What is Bafiertam (monomethyl fumarate), and what is it used for?
Bafiertam (monomethyl fumarate) is a prescription medicine used to treat relapsing forms of multiple sclerosis (MS), including clinically isolated syndrome, relapsing-remitting disease, and active secondary progressive disease, in adults.
It is not known if Bafiertam is safe and effective in children.
What are the side effects of Bafiertam?
Bafiertam may cause serious side effects including:
- allergic reaction (such as welts, hives, swelling of the face, lips, mouth or tongue, or difficulty breathing). Stop taking Bafiertam and get emergency medical help right away if you get any of these symptoms.
- PML (progressive multifocal leukoencephalopathy) a rare brain infection that usually leads to death or severe disability over a period of weeks or months. Tell your doctor right away if you get any of these symptoms of PML:
- herpes zoster infections (shingles), including central nervous system infections
- other serious infections
- decreases in your white blood cell count. Your doctor should do a blood test to check your white blood cell count before you start treatment with Bafiertam and while you are on therapy. You should have blood tests after 6 months of treatment and every 6 to 12 months after that.
- liver problems. Bafiertam may cause serious liver problems that may lead to liver failure, a liver transplant, or death. Your doctor should do blood tests to check your liver function before you start taking Bafiertam and during treatment if needed. Tell your doctor right away if you get any of these symptoms of a liver problem during treatment:
The most common side effects of Bafiertam include:
- flushing, redness, itching, or rash
- nausea, vomiting, diarrhea, stomach pain, or indigestion
- Flushing and stomach problems are the most common reactions, especially at the start of treatment, and may decrease over time. Call your doctor if you have any of these symptoms and they bother you or do not go away. Ask your doctor if taking aspirin before taking Bafiertam may reduce flushing.
These are not all the possible side effects of Bafiertam. Call your doctor for medical advice about side effects.
You may report side effects to FDA at 1-800-FDA-1088.

Multiple Sclerosis (MS)
Multiple sclerosis or MS is an autoimmune disorder in which brain and spinal cord nerve cells become demyelinated. This damage results in symptoms that may include numbness, weakness, vertigo, paralysis, and involuntary muscle contractions. Different forms of MS can follow variable courses from relatively benign to life-threatening. MS is treated with disease-modifying therapies. Some MS symptoms can be treated with medications.
MS (Multiple Sclerosis) vs. ALS (Amyotrophic Lateral Sclerosis)
ALS (amyotrophic lateral sclerosis, Lou Gehrig's disease) and MS (multiple sclerosis) are both diseases of the nervous system (neurodegenerative). ALS is a disease in which the nerve cells in the body are attacked by the immune system, although it's not considered an autoimmune disease by some scientists. MS is an autoimmune disease in which the insulated covering of the nerves (myelin sheath) in the CNS (central nervous system) degenerate, or deteriorate. Scientists don't know the exact cause of either problem. However, they have discovered that mutations in the gene that produces the SOD1 enzyme were associated with some cases of familial ALS. Scientists also theorize that multiple sclerosis may be caused by infection or vitamin D deficiency. ALS occurs between 50-70 years of age (the average age of occurrence ALS is 55), and mostly affects men. While MS occurs between 20-60 years of age, and mostly affects women. About 30,000 people in the US have ALS, and an average of 5,000 new diagnoses per year (that's about 15 new cases per week). Worldwide, MS affects more than 2.3 million people, with about 10,000 new cases diagnosed each year (that's about 200 new diagnoses per week).Some of the signs and symptoms of both diseases include muscle weakness, muscle spasms, problems walking, fatigue, slurred speech, and problems swallowing. ALS signs and symptoms that are different from MS include problems holding the head upright, clumsiness, muscle cramps and twitches, problems holding objects, and uncontrollable periods of laughing or crying. MS signs and symptoms that are different from ALS include vision problems, vertigo and balance problems, sexual problems, memory problems, depression, mood swings, and digestive problems. There is no cure for either disease, however the prognosis and life expectancy are different. Multiple sclerosis is not a fatal condition, while ALS progresses rapidly and leads to death.
Multiple Sclerosis (MS) Symptoms and Treatments
Multiple sclerosis (MS) symptoms vary from person to person and can last for days to months without periods of remission. Symptoms of MS include sexual problems and problems with the bowel, bladder, eyes, muscles, speech, swallowing, brain, and nervous system. The early symptoms and signs of multiple sclerosis usually start between ages 20-40. MS in children, teens, and those over age 40 is rare. Treatment options for multiple sclerosis vary depending on the type and severity of symptoms. Medications may be prescribed to manage MS symptoms.
Is Multiple Sclerosis (MS) Contagious?
Multiple sclerosis, or MS, is a degenerative disease of the covering around the nerves in the central nervous system (CNS). Researchers and doctors don't know the exact cause, but many theorize that it may be due to environmental triggers, an autoimmune disease, and viruses (infections). Symptoms and signs of MS include vision changes, paralysis, vertigo, heat intolerance, slurred speech, sexual dysfunction, and urinary incontinence (the inability to urinate). There's no vaccine or cure for MS, but the progression and symptoms of the disease can be treated.
What Is the Average Age at Which MS Is Diagnosed?
Multiple sclerosis (MS) is typically diagnosed between 20 to 40 years of age and affects women more than men.
Multiple Sclerosis (MS) and Pregnancy
Multiple sclerosis or MS is a central nervous system disease in which the immune system attacks the myelin sheath (the protective coating around nerves). Symptoms of MS include pain, sexual problems, fatigue, numbness and tingling, emotional changes, and depression.Women who are pregnant and have multiple sclerosis may have more difficulty carrying a pregnancy. Multiple sclerosis does not affect ability to conceive, and does not seem to affect fertility. MS symptoms during pregnancy may stay the same or get better; however, they may worsen after giving birth. Pregnancy decreases the number of relapses, but flares increase in the first 3-6 months after delivery. Pregnant women with MS may carrying a pregnancy more difficult to tell when labor starts, and there is an increased need to use forceps or vacuum to assist with delivery or b7 C-section (Cesarean birth) increases. Some treatment MS drugs may be safe to use during pregnancy; however, some drugs should not be taken, for example, baclofen (Gablofen, Lioresal), fluoxetine (Prozac, Sarafem), or solifenacin succinate (VESIcare), and most disease-modifying therapies (DMTs). Talk with your healthcare team about vitamins, supplements, and medications that you are taking if you are pregnant and have MS.
Can Stress Cause Multiple Sclerosis (MS)?
Multiple sclerosis (MS) results when your immune system attacks the cells of the brain and spinal cord. It is an autoimmune disease, a condition in which the body's immune system is misdirected and attacks its own cells. Stress can make it difficult for a person to manage MS symptoms. Regular exercise and mindful eating have been found to control the stress levels and overall health of people with MS.
Multiple Sclerosis (MS) Early Warning Signs and Types
Multiple sclerosis (MS) can be thought of as an immune-mediated inflammatory process involving different areas of the central nervous system (CNS) at various points in time. Early warning signs and symptoms of MS in children, teens, and adults are similar; however, children and teens with pediatric also may have seizures and a complete lack of energy. Adults with MS do not have these signs and symptoms. Other signs and symptoms of MS include inflammation of the optic nerve (optic neuritis), changes in vision, Wiping or having tissues around the eye and moving the eye may be painful, and double vision. There are four types of MS, relapsing-remitting MS (RRMS), secondary progressive MS (SPMS), primary progressive MS (PPMS), and progressive relapsing MD (PRMS).

Early Signs of Multiple Sclerosis
Multiple sclerosis (MS) is a progressive disease of the brain and spinal cord (central nervous system). MS is an autoimmune disease; the body’s immune system mistakenly attacks the cells of the nervous system.
Alternative Treatment (CAM) for MS
The term alternative therapy, in general, is used to describe any medical treatment or intervention that has not been scientifically documented or identified as safe or effective for a specific condition. Alternative therapy encompasses a variety of disciplines that range from diet and exercise to mental conditioning to lifestyle changes.
