What is the first line treatment for Cutaneous Larva Migrans?

The first-line treatment for cutaneous larva migrans is ivermectin. This is due to ivermectin's effectiveness against the larvae that cause this skin condition. Cutaneous larva migrans is typically caused by hookworm larvae, particularly Ancylostoma braziliense, which penetrate the skin and create a characteristic serpiginous rash. Ivermectin works by paralyzing and killing the larvae, leading to the resolution of symptoms.

While other medications listed might treat different parasitic infections, they are not effective against the specific larvae causing cutaneous larva migrans. Albendazole is used for intestinal helminth infections but is less effective for skin larvae. Chloroquine is primarily used to treat malaria and some autoimmune diseases and doesn't have any effect on cutaneous larva migrans. Amoxicillin is an antibiotic that is not indicated for parasitic infections, making it irrelevant for the treatment of this condition. Thus, ivermectin is the preferred choice for its targeted action against the causative agents of cutaneous larva migrans.
