Therapy recommendations

  • Mild course: symptomatic therapy (analgesics/pain relievers, antiemetics/anti-nausea drugs, antitussives/cough suppressants, if necessary).
  • Severe course with myocarditis (heart muscle inflammation)/myositis (muscle inflammation), fever: combination therapy of glucocorticoids and mebendazole (high dosage) or albendazole (benzimidazoles)Caution! Anthelmintics (drugs against worm diseases); uncertain efficacy against encystosed larvae.
  • In case of relevant exposure (e.g., consumption of meat products that have a high probability of containing live trichinella)
    • Within the past 7 days, without symptomatology (see below).
    • 8-30 days ago without symptomatology: initiate laboratory diagnostics: if negative, no further action (observation regarding development of symptoms).
    • > 30 days without symptomatology: no further diagnostics (observation regarding development of symptoms).

Exposure within the past 7 days without symptomatology

  • After relevant exposure (e.g., consumption of meat products highly likely to contain live trichinella):Drug prophylaxis: mebendazole 2 x 5 mg/kg body weight for 5 days. Contraindication: children under 2 years and during pregnancy.
