Question 1

What is Dimethyl fumarate?

Accepted Answer

Dimethyl fumarate is a medication classified as an Nrf2 activator. It works by modulating the immune system's response and reducing inflammation within the central nervous system.

This action helps protect nerve cells from damage and helps regulate the body's response to oxidative stress. It is used to manage certain chronic conditions by limiting the immune system's impact on the brain and spinal cord.

Question 2

What is Dimethyl fumarate used for?

Accepted Answer

Dimethyl fumarate is used to treat multiple sclerosis .

Question 3

How does Dimethyl fumarate work?

Accepted Answer

Mechanism of Action

The exact way dimethyl fumarate works to treat multiple sclerosis (MS) is not fully understood. However, medical experts believe it helps manage the condition by altering the immune system's response and protecting nerve cells from oxidative stress.

Reducing Inflammation

In multiple sclerosis, the immune system mistakenly attacks the protective covering of the nerves in the brain and spinal cord. Dimethyl fumarate is thought to change the behavior of the immune system to decrease the inflammation that causes these attacks. By reducing this inflammation, the medication may help decrease the frequency of relapses and slow the progression of physical disability.

Cellular Protection

Dimethyl fumarate and its active metabolite, monomethyl fumarate, have been shown to activate a specific pathway in the body known as the Nrf2 pathway . This pathway is involved in how cells respond to oxidative stress, which is a process that can damage or kill cells. By activating this pathway, the medication may help protect the brain and spinal cord cells from damage caused by the disease.

Question 4

What are the brand names for Dimethyl fumarate?

Accepted Answer

and others

Always consult with a healthcare professional about potential side effects.

Question 7

What drug class is Dimethyl fumarate?

Accepted Answer

Dimethyl fumarate belongs to the immunomodulator drug class.

Question 8

What is the dosage of Dimethyl fumarate and how do I take it?

Accepted Answer

How to Take

Dimethyl fumarate comes as a delayed-release capsule to be taken by mouth. It is usually taken twice every day. It is important to swallow the capsules whole; do not crush, chew, or break them, and do not sprinkle the contents on food.

Taking with Food

You may take this medication with or without food. However, taking it with a meal or a high-fat, high-protein snack may help reduce skin flushing, which is a common side effect.

Missed Dose

If you miss a dose, take it as soon as you remember. If it is almost time for your next scheduled dose, skip the missed dose and continue with your regular dosing schedule. Do not take two doses at the same time to make up for a missed one.

Question 9

Is Dimethyl fumarate safe during pregnancy and breastfeeding?

Accepted Answer

Pregnancy

There is limited information regarding the safety of dimethyl fumarate in pregnant women. Animal studies have indicated that high doses of the medication may lead to fetal harm, including lower birth weight and delayed bone development. It is not yet known if these risks apply to humans.

If you are pregnant or planning to become pregnant, it is important to discuss the risks and benefits of continuing treatment with your healthcare provider. A pregnancy exposure registry may be available to collect information about the health of individuals and their babies who are exposed to the drug during pregnancy.

Breastfeeding

It is currently unknown if dimethyl fumarate passes into human breast milk or if it has any effect on a nursing infant or milk production. Because of the lack of data, patients should consult with a healthcare professional to determine the safest approach to infant feeding while taking this medication.

Question 10

What forms and strengths does Dimethyl fumarate come in?

Accepted Answer

Dimethyl fumarate is available in the following form:

Delayed-release oral capsules: These capsules are designed to be swallowed whole so that the medication is released in the intestines rather than the stomach.

Question 11

What is the FDA approval status of Dimethyl fumarate?

Accepted Answer

FDA Approval Status

Dimethyl fumarate received its initial approval from the U.S. Food and Drug Administration (FDA) in 2013. It is indicated for the treatment of relapsing forms of multiple sclerosis (MS) in adults, which includes clinically isolated syndrome, relapsing-remitting disease, and active secondary progressive disease.

Safety Communications

The FDA has issued safety communications regarding the risk of progressive multifocal leukoencephalopathy (PML), a rare and potentially fatal opportunistic viral infection of the brain. This risk is associated with a decrease in lymphocyte counts (lymphopenia) caused by the medication. The FDA required updates to the drug label to include information about these cases and to recommend monitoring of white blood cell counts before and during treatment.

Regulatory Warnings

While dimethyl fumarate does not currently require a Risk Evaluation and Mitigation Strategy (REMS) program, the FDA mandates specific warnings in the prescribing information regarding several serious risks:

Anaphylaxis and Angioedema: Serious allergic reactions can occur at any time during treatment.

Progressive Multifocal Leukoencephalopathy (PML): A rare brain infection that has occurred in patients with low lymphocyte counts.

Lymphopenia: Dimethyl fumarate may decrease lymphocyte counts; blood tests are required before starting and every 6 to 12 months during treatment.

Liver Injury: Reports of clinically significant liver injury have led to requirements for liver function testing before and during therapy.

Flushing: A common side effect that is documented in the safety profile and may require clinical management.

Question 12

What should I know about Dimethyl fumarate and withdrawal?

Accepted Answer

Discontinuing Dimethyl Fumarate

There is currently no evidence that dimethyl fumarate causes physical dependence or a specific withdrawal syndrome when a person stops taking it. However, because this medication is used to manage a chronic condition, stopping it can have significant effects on your health.

Risk of Relapse

The primary concern when stopping dimethyl fumarate is the return of multiple sclerosis (MS) disease activity. If the medication is discontinued, you may experience:

A return of previous MS symptoms.

New or worsening relapses.

Increased inflammation in the central nervous system.

Medical Supervision

You should not change your dose or stop taking this medication without talking to your healthcare provider first. If you are experiencing bothersome side effects, such as flushing or gastrointestinal issues, your doctor can help manage these symptoms or determine if a different treatment is necessary. If you must stop the medication, your doctor will monitor you for signs of MS progression.
