What is Tecfidera?

Dimethyl fumarate which is marketed under the brand name, Tecfidera is a prescription medication used to treat adults with various relapsing forms of multiple sclerosis, including clinically isolated syndrome, relapsing-remitting disease, and active secondary progressive disease.

It can decrease the risk of MS relapse in a patient by up to 49 percent over the course of 2 years, as well as lessen the risk of further regression of physical disability by approximately 38 percent.

If you or someone you know is suffering from a relapsing form of multiple sclerosis, the prescription medication Tecfidera may be able to help. Read on to learn everything you need to know about this medication.

How Does Tecfidera Work?

Multiple sclerosis is a disease in which the immune system attacks the myelin sheath of nerve cells causing dysfunctioning of the nerves. Tecfidera is a medication that belongs to a class of medications known as Nrf2 activators. Dimethyl fumarate, the active ingredient in Tecfidera, works by helping reduce inflammation in the body and prevent further damage to the nerve cells caused by the immune system attacking the myelin sheath. By protecting the nerve cells from damage, Tecfidera may help reduce symptoms of multiple sclerosis as well as lessen the risk of relapse or frequency of episodes of the disease.

How is Tecfidera Taken?

It is vital that you take your prescription Tecfidera as per the recommendations of your doctor and the instructions on the prescription label. Your doctor will determine the best dosage of the medication for you based on a variety of factors including your tolerance level, and any other medications you are currently taking, etc.

Tecfidera is taken orally with or without food usually twice a day. It is common that your doctor will advise that you start taking the medication at a lower dose and up your dosage after 7 days. Taking the drug in combination with food or taking a plain aspirin (non-enteric coated) 30 minutes before taking the medication may help reduce a possible side effect of flushing.

Tecfidera capsules are to be swallowed whole; avoid opening, crushing, or chewing the capsule which can release the whole drug at once, elevating the risk of its side effects. It is important to take the medication as regularly as possible, around the same time of day to ensure the highest efficacy.
