Pyrethrins and piperonyl butoxide are commonly used as insecticides and are typically applied topically to treat head lice and pubic lice infestations.

Pyrethrins are natural insecticides derived from the chrysanthemum flower, which paralyze and kill lice and their eggs by disrupting their nervous system. Piperonyl butoxide enhances the effectiveness of pyrethrins by inhibiting enzymes that break down the insecticide.

When used as directed, pyrethrins and piperonyl butoxide are generally safe. However, some individuals may experience mild skin irritation or allergic reactions. It is important to avoid contact with the eyes and mouth and to follow the instructions provided by the healthcare professional or product label.

Limited data is available regarding their safety during pregnancy or breastfeeding. It is advisable to consult a healthcare professional before using these products if pregnant or breastfeeding.

Typically, the product is applied to dry hair and left on for a specific amount of time as directed (usually around 10 minutes). Afterward, it should be rinsed thoroughly with water. The process may need to be repeated after a week to ensure complete eradication of the lice and their eggs.
