Head lice, scabies and worm infections are common and treatable. This page brings together our guides on lice, parasites and the antiparasitic medicine ivermectin.
Our lice and parasites guides

Key points
- Head lice can usually be treated at home with an over-the-counter lotion and a lice comb.
- Ivermectin tablets need a diagnosis and a prescription. The dose depends on the infection and your body weight.
- Never take ivermectin products made for animals.
See a doctor if
You think you have a worm infection or scabies, lice keep coming back after two different treatments, or the skin looks infected.
