Dimethyl Fumarate

Tecfidera 

Tecfidera is an effective oral medication for managing relapsing forms of multiple sclerosis (MS). It modulates the immune system and reduces inflammation to protect nerve cells, which helps decrease flare-ups and slow disease progression. Starting with a dose of 120 mg twice daily, which increases to 240 mg, Tecfidera is known for its ability to reduce the frequency of MS symptoms and physical disabilities. While generally well-tolerated, it requires monitoring for potential side effects like liver damage and low white blood cell counts. Always taken under medical supervision, Tecfidera is a pivotal treatment in managing MS.

Product Overview

Tecfidera (dimethyl fumarate) is a leading oral medication for treating relapsing forms of multiple sclerosis (MS), created to modulate the immune system and lower inflammatory responses that can damage nerve cells in the brain and spinal cord. This medication is primarily used to decrease the frequency of flare-ups & slow the progression of physical disabilities associated with MS. The typical recommended dosage for adults starts with 120 mg twice daily during the first week, increasing to 240 mg daily. Patients must follow their healthcare provider’s instructions carefully and undergo regular monitoring to manage side effects and ensure effectiveness. 

Tecfidera can be taken with or without food, although consuming it with food may help mitigate some gastrointestinal side effects, such as flushing and stomach discomfort. Tecfidera works by activating the Nrf2 pathway, which helps protect nerve cells from oxidative stress & inflammation, potentially reducing flare-ups and delaying disease progression. However, it can cause multiple side effects, from flushing and gastrointestinal issues to more severe conditions like low white blood cell counts and liver damage. 

Regular blood tests are recommended for patients to monitor their health, especially liver function and lymphocyte counts. Safety precautions with Tecfidera include avoiding live vaccines and minimizing exposure to infections due to the drug’s impact on the immune system. Women should discuss pregnancy plans with their healthcare provider due to the unknown risks of taking Tecfidera during pregnancy. Patients considering Tecfidera should be aware of potential interactions with other medications and supplements, particularly those that affect the immune system or liver enzyme levels. Alternatives to Tecfidera include other oral treatments, injectable medications, and infusion therapies, which may be preferable depending on individual patient needs and medical histories.

What Are the Forms & Strengths of Tecfidera?

Tecfidera is available in the following forms and strengths:

• Oral delayed-release capsules: 120 mg and 240 mg.

What Are the Recommended Dosage of Tecfidera?

The recommended dosage of Tecfidera (dimethyl fumarate) for adults, including those newly starting the medication and those continuing treatment, generally follows this protocol:

• Initial Dose:
  • Start with 120 mg twice daily (morning and evening).
  • This initial dose is usually maintained for the first 7 days.

How to Use Tecfidera? 

• Dosage: Typically, start with a lower dose to improve gastrointestinal tolerability and gradually increase to the full dosage as directed by your healthcare provider.
• Administration: Take Tecfidera capsules orally with or without food. Swallow the tablets whole; do not crush, chew, or sprinkle on food.
• With Food: Taking Tecfidera with food, especially protein-rich food, can help minimize common side effects like flushing and stomach upset.
• Timing: It’s usually taken twice a day, roughly 12 hours apart; maintaining a consistent schedule helps maintain steady medication levels in your body.
• Flushing Management: If flushing occurs, over-the-counter aspirin (taken 30 minutes before Tecfidera) may help, but first discuss this with your healthcare provider.
• Monitoring: Routine blood tests may be required to monitor your white blood cell counts and other parameters, as Tecfidera can decrease immune cell levels, increasing infection risk.

[Note: Your healthcare specialist will decide the right amount for you as per your condition, following medicine guidelines & studies on the drug. They’ll adjust it as needed over time.]

How Does Tecfidera Work?

Tecfidera (dimethyl fumarate) modulates the immune system, although its exact mechanism in treating multiple sclerosis (MS) isn’t fully understood. It’s believed to protect nerve cells from damage and reduce inflammation, key factors in MS. Tecfidera activates the Nrf2 pathway. This protective response helps cells defend against oxidative stress, which can damage or kill cells. By decreasing inflammation and protecting against cell damage, Tecfidera helps to slow the progression of MS and decrease the frequency of flare-ups. This action makes it effective in managing both relapsing-remitting MS & other forms of the disease, helping to maintain nerve function and reduce overall disability.
