Treatment

Medical Care

See the list below:

  • Therapy in patients with visceral larva migrans (VLM) is aimed at relieving symptoms and is intended to diminish the host inflammatory response to the parasite. Corticosteroids and antihistamines are often used for this purpose. Patients with myocarditis or CNS disease should always be treated with corticosteroids.

  • Antiparasite agents, such as mebendazole, may help reduce symptoms; however, systemic treatment with anthelminthics can result in hypersensitivity reactions. Clinical trials have raised questions about their efficacy.

  • Attempt to identify the source of infection. Infected puppies and kittens should be treated with appropriate anthelminthic agents.
