What is Vumerity?
Vumerity (diroximel fumarate) is a prescription medicine used to treat relapsing forms of multiple sclerosis in adults (including clinically isolated syndrome, relapsing-remitting disease, and active secondary progressive disease).
Exactly how Vumerity works in treating multiple sclerosis is not known.
It is not known if Vumerity is safe and effective in children.
You should not use Vumerity if you have had a severe allergic reaction to diroximel fumarate, or if you also use dimethyl fumarate (Tecfidera).
Before taking this medicine
You should not use Vumerity if:
you have had a severe allergic reaction to diroximel fumarate or dimethyl fumarate (Tecfidera); or

low white blood cell (WBC) counts.

Vumerity and Tecfidera are administered in the same way and used to treat the same condition, multiple sclerosis (MS). They also have the same active metabolite, which means that they have the same therapeutic effect - work the same way - in people with MS.
However, Vumerity and Tecfidera do have different chemical structures and Vumerity is better tolerated and causes fewer gastrointestinal problems compared with Tecfidera. Continue reading
Vumerity (diroximel fumarate) is a delayed-release capsule used to treat relapsing forms of the autoimmune disorder multiple sclerosis.
Vumerity is thought to have an effect as early as 24 weeks after patients start taking it, based on the results of trials conducted using Tecfidera (dimethyl fumarate), which has the same active metabolite as Vumerity. Continue reading
It is not yet known exactly how Vumerity works - what its mechanism of action is - in the treatment of MS.
Vumerity's active metabolite, monomethyl fumarate (MMF), is thought to modulate the immune system and have anti-inflammatory and anti-oxidative properties. MMF actives Nrf2 and HCAR2. Continue reading
Vumerity (diroximel fumarate) and Mayzent (siponimod) are both small molecule drugs used for the treatment of multiple sclerosis (MS), which were approved by the US Food and Drug Administration (FDA) in 2019. Vumerity is used in patients with relapsing-remitting MS (RRMS), while Mayzent is used in patients with secondary progressive MS (SPMS), although both have been approved by the FDA for use in all the same types of MS.
Vumerity and Mayzent belong to different drug classes. Vumerity is an immunomodulator, while Mayzent is a Sphingosine 1-phosphate (S1P) receptor modulator. They also differ in a number of other ways. Continue reading
