MS Medicine Glatiramer Acetate (Copaxone, Glatopa) Poses Risk of Rare but Serious Allergic Reaction, Says FDA

In a release issued January 22, 2025, the FDA warned multiple sclerosis patients, caregivers, and healthcare professionals of a rare but serious risk associated with the medicine glatiramer acetate, also known on the market as Copaxone and Glatopa.

An FDA-approved medicine used in the treatment of “relapsing forms of MS,” glatiramer acetate–under the brand name Copaxone, branded generic name Glatopa, and other generic products–is injected daily or three times per week, as required by a given dosage.

Officials have identified anaphylaxis as a serious allergic reaction that may occur at any time in patients taking the medicine for the treatment of multiple sclerosis (MS). The reaction can unfold soon after the first dose(s) is administered, or even months and years after a patient has started the treatment. In most cases in which MS patients undergo anaphylaxis on glatiramer acetate, symptoms are exhibited an hour after injection. However, anaphylaxis has also been known to require hospitalization or lead to death.

Patients and caregivers are also advised that early symptoms of anaphylaxis can often appear as symptoms of a temporary, post-injection reaction, which is common. Vigilance is important in order to determine whether a patient is displaying symptoms of anaphylaxis, which is rare, but which can require treatment as symptoms become more severe over a duration. As such, patients who experience a sustained reaction following an injection should contact their medical provider right away.

In response to the FDA’s finding, the agency will be introducing a new Boxed Warning explaining the risk of glatiramer acetate.
