Jaxteran

Dimethyl fumarate, the active ingredient in Jaxteran, is an immunomodulating agent presented as an oral tablet for oral use. It is indicated for the treatment of multiple sclerosis and psoriasis in adult patients.

GNH USA supplies Jaxteran as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide.

Dimethyl fumarate is employed in conditions where modulation of immune activity and oxidative stress provides clinical benefit.

Multiple sclerosis: reduces relapse frequency and slows progression of disability. Relapsing‑remitting multiple sclerosis: improves disease activity markers and patient outcomes. Psoriasis: decreases skin lesion severity and improves quality of life.

Dimethyl fumarate may cause a range of adverse reactions, which are categorized by frequency and severity.

Common Side Effects: - Flushing: transient redness and warmth, often mild. - Gastrointestinal upset: nausea, abdominal pain, or diarrhea. - Lymphopenia: reduced lymphocyte count, usually mild. - Headache: occasional mild to moderate pain.

Serious or Rare Side Effects: - Progressive multifocal leukoencephalopathy (PML): rare but potentially fatal brain infection. - Severe liver injury: marked elevation of liver enzymes. - Anaphylaxis: acute severe allergic reaction requiring immediate medical attention. - Severe infections: increased susceptibility due to immune modulation. - Hematologic abnormalities: rare cases of severe lymphopenia or neutropenia.

Prior to initiating therapy, clinicians should evaluate patient-specific risk factors and monitor relevant parameters.

Monitor lymphocyte counts: perform baseline and periodic blood tests. Assess liver function: check hepatic enzymes before and during treatment. Avoid in active infection: defer initiation until infection resolves. Counsel about flushing: advise taking with food and avoiding hot environments. Store at ambient temperature: keep in original packaging, protect from moisture and direct sunlight.

Dimethyl fumarate can interact with other medicines, influencing safety or efficacy.

Major Interactions (Avoid): - Live vaccines: increased risk of infection; avoid concurrent use. - Potent immunosuppressants: may amplify immunosuppression and infection risk.

Moderate Interactions (Monitor Closely): - Antiepileptic drugs: possible reduction in dimethyl fumarate exposure. - Statins: may raise risk of myopathy. - NSAIDs: can exacerbate gastrointestinal irritation.
