Pyrethrin and piperonyl butoxide shampoo is utilized for the treatment of lice infestations in adults and children aged 2 years and older. Lice are small insects that attach themselves to the skin on the head, body, or pubic area. Pyrethrin and piperonyl butoxide belong to a class of medications known as pediculicides. They function by effectively killing lice.

Uses and Dosage

Pyrethrin and piperonyl butoxide are available in shampoo form for application to the skin and hair. Typically, it is applied to the skin and hair in two or three treatments, with the second treatment administered 7-10 days after the first one. In some cases, a third treatment may be necessary, as advised by your doctor.

Use pyrethrin and piperonyl butoxide shampoo precisely as directed. Do not exceed or reduce the dosage, or use it more frequently than directed on the package label or prescribed by your doctor.

The package label provides an estimate of the amount of shampoo required based on your hair length. Ensure you apply enough shampoo to cover your entire scalp area and hair.

Pyrethrin and piperonyl butoxide shampoo should only be used on the skin, hair, and scalp. Avoid contact with the eyes, nose, mouth, or vagina. Refrain from using it on your eyebrows or eyelashes.
