Ivermectin is used to treat onchocerciasis (river blindness), strongyloidiasis (threadworm infection), scabies (particularly when topical treatment has failed), and head lice infestations. Healthcare providers may also prescribe it for other parasitic infections.
Ivermectin binds to and activates glutamate-gated chloride channels in invertebrate nerve and muscle cells, causing paralysis and death of susceptible parasites.
Ivermectin is typically administered as a single oral dose. Common side effects may include headache, dizziness, muscle pain, or rash. It should be used with caution in patients with compromised blood-brain barrier function and is generally avoided during pregnancy unless the benefits outweigh the risks.
