What is the active ingredient in pediculicides?

The active ingredient in pediculicides is specifically designed to target and eliminate lice infestations. Pediculicides are specialized insecticidal agents formulated to be effective against lice, which are parasitic insects that can infest human hair and lead to conditions such as head lice. These products work by either suffocating the lice, disrupting their nervous system, or outright killing them upon contact or ingestion.

In contrast, antihistamines, antibiotics, and antifungals serve different purposes. Antihistamines are primarily used to alleviate allergic reactions, antibiotics treat bacterial infections, and antifungals combat fungal infections. These substances would not effectively address a lice infestation, making the class of drugs known as insecticides for lice the appropriate choice for treatment.
