What Is the Best Medicine for Treating Head Lice?

The best medicine for removing head lice is a medicated lice treatment, such as a shampoo, lotion or cream rinse, that kills the lice and their eggs, according to KidsHealth. These types of treatments can typically be purchased at grocery stores and pharmacies.

Medicated lice treatments should not be used on children 2 years old or younger, as stated by KidsHealth. Using a fine tooth comb to remove the lice and eggs from wet hair can be done in place of using medicated treatments. After removing lice, repeat the treatment seven to 10 days later to remove any newly hatched lice.
