Updated: Feb 16, 2016

Medical Care

Chemotherapy is the treatment of choice in most patients with liver, lung, or eye involvement. Occasionally, ocular involvement requires ocular surgery.

Treatment includes mebendazole, thiabendazole, corticosteroids, and specific organ treatment. The prognosis of toxocariasis is generally favorable.


Surgical Care

For liver or lung involvement, no surgical care is required.

For ocular involvement with retinal detachment, laser treatment may be considered.



A consultation with an ophthalmologist is indicated in cases of ocular larva migrans.

Consultation with a neurologist is indicated in cases of brain involvement with neurologic symptoms or seizures.

Consultation with an infectious disease specialist may be indicated when questions exist regarding the indications for and selection of treatment for visceral larva migrans.



No diet restrictions are required.



No activity restriction is required.
