Side effect details
You may wonder how often certain side effects occur with this drug. Here’s some detail on certain side effects this drug may cause. To learn more about Vumerity and side effects, see this article.
Infections
In rare cases, Vumerity can cause an infection that may be serious.
Progressive multifocal leukoencephalopathy
Some people could develop progressive multifocal leukoencephalopathy (PML) while taking Vumerity. PML is a rare brain infection that can lead to severe disability or death.
Possible symptoms of PML include:
- weakness on one side of the body
- confusion or trouble remembering things
- clumsiness
- vision problems
- personality changes
In clinical studies, PML occurred in people with lymphocytopenia (low white blood cell levels). Lymphocytopenia is a possible side effect of Vumerity. (To learn more, see the “Low white blood cell level” section after.)
To watch for this side effect, your doctor should check your white blood cell level before and during your Vumerity treatment.
Shingles
Shingles infection may occur while taking Vumerity. Shingles is caused by a recurring infection with the same virus that causes chickenpox. Anyone who’s ever had chickenpox is at risk of shingles.
Shingles infection symptoms vary greatly and can include:
- mild to severe pain on one side of the body
- tingling on one side of the body
- rash that may be itchy, turn into fluid-filled blisters, and crust over
- fever or chills
- headache
Cases of shingles have been reported after Vumerity was made available to the public. However, it’s not known if Vumerity was the cause of shingles in these cases. It’s also unknown how many people have reported experiencing shingles while taking Vumerity.
Low white blood cell level
Vumerity can cause lymphocytopenia (a low level of white blood cells). Lymphocytes are immune system cells that circulate in the blood to fight infection. Lymphocytopenia could make your body unable to fight infections as well.
A blood test can be done to check your white blood cell level. Your doctor will order this blood test before you start taking Vumerity. You’ll also have this test done regularly during your treatment.
If you have any concerns about your white blood cell level, talk with your doctor.
Liver damage
Liver damage may occur in some people taking Vumerity.
Increased levels of liver enzymes can be an early sign of liver damage before any symptoms appear. Continued liver damage could possibly lead to liver failure.
A blood test that measures your liver enzyme levels is used to check for liver damage. Your doctor will order this blood test before you start treatment with Vumerity. You’ll also have this test done regularly during your treatment. If your liver enzyme levels become too high, your doctor may have you stop taking Vumerity.
Symptoms of liver damage may include fatigue, decreased appetite, right-sided abdominal pain, and jaundice (yellowing of the skin or whites of the eyes). If you have any of these symptoms during your Vumerity treatment, talk with your doctor.
Abdominal pain
Abdominal pain is a common side effect of Vumerity.
The FDA approved Vumerity based on its similarity to dimethyl fumarate (Tecfidera). Vumerity and Tecfidera have very similar side effects. However, the risk of abdominal pain (and other digestive side effects) may be different with these drugs. According to a clinical study, the risk of digestive side effects may be lower with Vumerity than with Tecfidera.
In this study, abdominal pain and digestive side effects occur most often in the first month of Vumerity treatment. For most people, these side effects become mild or go away over time.
If you experience bothersome digestive side effects during your treatment, talk with your doctor.
ALLERGIC REACTIONFor some people, Vumerity oral capsule can cause an allergic reaction.
In general, symptoms of allergic reaction can be mild or serious.
Ways to manage
For mild allergic reaction symptoms, such as a mild rash, call your doctor right away. They may recommend treatments to help manage your symptoms. They’ll also let you know whether you should keep taking the medication.
For severe allergic reaction symptoms, such as swelling or trouble breathing, call 911 or your local emergency number right away. These symptoms require immediate medical care because they can become life threatening. If you’ve had a serious allergic reaction to Vumerity oral capsule, your doctor may recommend taking a different medication instead.
As with all medications, the cost of Vumerity can vary. The actual price you’ll pay depends on your insurance plan, your location, and the pharmacy you use.
Financial and insurance assistance: If you need financial support to pay for Vumerity, or if you need help understanding your insurance coverage, help is available.
Vumerity’s manufacturer, Biogen, offers support coordinators to help with questions about cost. For more information and to find out if you’re eligible for support, call 800-456-2255 or visit the program website.
Generic version:Vumerity is not available in a generic form. A generic drug is an exact copy of the active ingredient in a brand-name medication. Generics tend to cost less than brand-name drugs.

The following information describes dosages that are commonly used or recommended. However, be sure to take the dosage your doctor prescribes for you. Your doctor will determine the best dosage to fit your needs.
Drug forms and strengths
Vumerity comes as a delayed-release oral capsule that you swallow whole. “Delayed release” means the capsule is released into your body after it passes through your stomach.
Vumerity is available in one strength: 231 milligrams (mg).
Dosage for multiple sclerosis and clinically isolated syndrome
The recommended starting dosage for Vumerity is 231 mg (one capsule) taken twice per day for 7 days.
After this, your doctor will likely increase your dosage to 462 mg (two capsules) taken twice per day. This is the recommended maintenance (long-term) dosage of Vumerity.
If you have bothersome side effects* with the maintenance dosage, your doctor may temporarily decrease your dosage back to the starting dosage. This can help your body get used to the medication. Your doctor will increase your dosage back to the maintenance dosage within 4 weeks. If you’re unable to tolerate the maintenance dosage at this stage, your doctor will likely recommend that you stop Vumerity and switch to a treatment better suited for you.
* Vumerity commonly causes flushing at the start of treatment. Flushing is likely to improve as your body adjusts to Vumerity. If you have this side effect, it may help to take Vumerity with food (see just below). If flushing continues, talk with your doctor. They may recommend taking a dose of uncoated aspirin 30 minutes before a dose of Vumerity.
About taking Vumerity
Below you’ll find information about key dosage issues.
- When to take: You should take Vumerity twice per day, once in the morning and once in the evening. Taking the medication around the same time of day helps keep a steady level of the drug in your body. This helps Vumerity work effectively.
- If you miss a dose: If you miss a dose, take it as soon as possible. But if it’s almost time for your next dose, skip the missed dose and take your next scheduled dose as usual. Do not take two doses together to make up for missing a dose.
- Taking Vumerity with food: You can take Vumerity with or without food. But if you have flushing with Vumerity, it may help to take your dose with a low calorie, low fat meal or snack. This should contain no more than 700 calories and no more than 30 grams of fat. Foods high in calories and fat can prevent your body from absorbing Vumerity, which can make the drug less effective.
- Crushing, splitting, or chewing Vumerity: You should not crush, split, or chew Vumerity. Swallow the capsule whole with a nonalcoholic drink.
- Length of use: Vumerity is meant to be used as a long-term treatment. If you and your doctor determine that Vumerity is safe and effective for you, you’ll likely take it long term.
- Length of time to work: Vumerity starts working as soon as you start taking it, but you may not notice it working. The drug helps prevent worsening symptoms of multiple sclerosis (MS) and clinically isolated syndrome (CIS), and it helps slow your condition from progressing. Talk with your doctor to learn more about how the drug works.

Overdose
Do not take more Vumerity than your doctor recommends. For some drugs, doing so may lead to unwanted side effects or overdose.
What to do in case you take too much Vumerity
If you think you’ve taken too much of this drug, call your doctor. You can also call America’s Poison Centers at 800-222-1222 or use its online tool. However, if your symptoms are severe, call 911 or your local emergency number, or go to the nearest emergency room right away.
You may wonder how Vumerity compares with other medications that are prescribed for similar uses, such as Tecfidera. The drugs have some similarities and some differences.
Vumerity and Tecfidera are FDA approved for use in certain adults to treat relapsing-remitting multiple sclerosis (RRMS), active secondary progressive MS (SPMS), and clinically isolated syndrome (CIS).
Both drugs come as a delayed-release oral capsule that is taken twice per day. (“Delayed release” means a drug is released into your body after it passes through your stomach.)
Vumerity contains the active drug diroximel fumarate. Tecfidera contains the active drug dimethyl fumarate. These drugs both belong to the Nrf2 activator drug class, so they work similarly. The active drugs are both converted by the body into an active substance called monomethyl fumarate (MMF). Then, MMF works in the body to help treat MS or CIS.
In general, Vumerity and Tecfidera are known to cause similar side effects. However, a clinical trial showed that Vumerity may be less likely to cause digestive side effects than Tecfidera.
To learn more about how Vumerity compares with Tecfidera, talk with your doctor or pharmacist. You can also refer to the prescribing information for Vumerity and Tecfidera.
The Food and Drug Administration (FDA) approves prescription drugs such as Vumerity to treat certain conditions. Vumerity may also be used off-label for other conditions. Off-label drug use is when an FDA-approved drug is prescribed for a purpose other than what it’s approved for.
Vumerity for multiple sclerosis
Vumerity is FDA approved to treat the following forms of multiple sclerosis (MS) in adults:
- Relapsing-remitting MS (RRMS): RRMS involves periods of relapse (when symptoms worsen) and periods of remission (when symptoms improve or go away).
- Active secondary progressive MS (SPMS): Active SPMS involves gradually worsening symptoms with no periods of remission.
- Clinically isolated syndrome (CIS): CIS is an episode of MS-like symptoms that lasts at least 24 hours. CIS may or may not develop to be MS.
With MS, your immune system attacks the protective layer around nerves in your brain and spinal cord. This prevents your nerves from communicating effectively with other parts of your body.
Symptoms of MS can vary from person to person, and they can range from mild to severe. Examples include:
- muscle weakness, stiffness, or spasms
- numbness or tingling feelings
- pain
- fatigue
- mobility problems
- vision changes, such as blurry vision or double vision
- problems with thinking or learning
- bladder or bowel problems
Vumerity is a type of MS treatment called a disease-modifying therapy (DMT).
Vumerity is used to help prevent MS relapses (periods when symptoms worsen) and to help slow the progression of your condition. The drug also helps prevent new or worsening brain lesions (areas of nerve damage in the brain that can be seen with an MRI scan). It also helps slow worsening physical symptoms of MS, such as mobility problems. To learn more about how effective Vumerity is for MS, talk with your doctor or see the drug’s prescribing information.
Vumerity may be prescribed by itself or with other drugs that treat symptoms of MS flare-ups. An example includes corticosteroids, such as prednisone (Rayos).
Vumerity and children
Vumerity is not FDA approved for any uses in children under 18 years old. The manufacturer has not studied the drug in this age group.
Vumerity can interact with some other medications. It may also interact with certain supplements as well as certain foods.
Before taking Vumerity, talk with your doctor and pharmacist. Tell them about all prescription, over-the-counter, and other drugs you take. Also tell them about any vitamins, herbs, and supplements you take. Sharing this information can help you avoid potential interactions.
Interactions with medications, foods, and supplements
Below is a list of medications, supplements, and foods that can interact with Vumerity. This list does not contain all drugs that may interact with Vumerity. If you have questions about drug interactions that may affect you, ask your doctor or pharmacist.
| Medications that can interact with Vumerity | dimethyl fumarate (Tecfidera) |
|---|---|
| Foods that can interact with Vumerity | high fat, high calorie foods |
Alcohol interaction
You shouldn’t consume alcohol at the same time as taking a dose of Vumerity. Alcohol can prevent your body from absorbing Vumerity correctly, which can make the drug less effective at treating your condition.
Additionally, it may not be safe to consume alcohol throughout treatment with Vumerity. Drinking alcohol during treatment may increase the risk and severity of certain side effects. Examples include flushing, nausea, and liver problems.
If you have questions about the safety of drinking alcohol while taking Vumerity, talk with your doctor or pharmacist.
Vumerity is a disease-modifying therapy (DMT) for multiple sclerosis (MS) and clinically isolated syndrome (CIS). Other DMT drugs are available that can treat your condition.

Here are answers to some frequently asked questions about Vumerity.
Can Vumerity increase the risk of cancer?
No, Vumerity is not known to increase the risk of cancer. This side effect wasn’t reported in clinical trials of Vumerity.
Other disease-modifying therapies (DMTs) that are used to treat multiple sclerosis (MS) may increase the risk of developing certain cancers. Examples include cladribine (Mavenclad), fingolimod (Gilenya), and ocrelizumab (Ocrevus). These drugs work by reducing activity in parts of your immune system, which can make it harder for your body to find and kill cancer cells.
Although Vumerity is a type of DMT, it works differently than the drugs just mentioned. To learn more about how Vumerity works, see the following section.
Talk with your doctor if you have questions or concerns about possible risks with Vumerity.
What is Vumerity’s mechanism of action? How does it work?
Doctors don’t fully understand Vumerity’s mechanism of action, or how it works to treat certain forms of multiple sclerosis (MS) or clinically isolated syndrome (CIS).
With these conditions, your immune system attacks the protective layer around the nerves in your brain and spinal cord. This causes inflammation (swelling) that can damage nerves and cause oxidative stress (an imbalance of free radicals and antioxidants). Oxidative stress can worsen nerve damage and inflammation. This process prevents your nerves from communicating effectively with other parts of your body, which leads to symptoms of MS and CIS.
It isn’t fully understood how Vumerity works. However, one way that your body reduces oxidative stress is through a communication pathway called the Nrf2 pathway. Vumerity has been shown to activate this pathway. So it may reduce the oxidative stress that helps drive the nerve damage in MS. This may help prevent MS relapses (periods when symptoms worsen) and slow the progression of your condition.
For more information about how Vumerity works to treat your condition, talk with your doctor.
Before taking Vumerity, discuss your health history with your doctor. Vumerity may not be right for you if you have certain medical conditions or other factors affecting your health. Be sure to talk with your doctor if any of the following apply to you:
- taking dimethyl fumarate (Tecfidera)
- liver problems
- kidney problems
- low white blood cell count
- infections
- previous allergic reaction to this or a similar drug
- pregnancy
- breastfeeding
