Key takeaways
Diroximel fumarate (Vumerity) and glatiramer (Copaxone, Glatopa) are both medications used to treat relapsing forms of multiple sclerosis (MS). However, they belong to different medication classes. Diroximel fumarate is a fumaric acid derivative taken orally, while glatiramer is a disease-modifying therapy injected under the skin. Diroximel fumarate comes as a capsule taken twice daily, whereas glatiramer can be injected either daily or three times a week, depending on the dose. Diroximel fumarate does not have a generic version, but glatiramer is available as a generic. Common side effects of diroximel fumarate include stomach upset and flushing, while glatiramer often causes injection site reactions like redness and pain. Diroximel fumarate may suppress your immune system and increase the risk of infection. Glatiramer hasn't been shown to weaken your immune system. Both medications can potentially cause liver damage.
