Pedemy All toolsChoose the problem and the child's age to get the right treatment, how to repeat it, who else to treat, and school advice.
This tool covers four common pediatric infestations and fungal infections in one place: head lice, scabies, pinworm, and tinea (ringworm) of the scalp and body. The first question picks the problem, and the next picks the age or type, because age limits drive most treatment choices.
Each result gives the first-choice treatment, alternatives for resistance or failure, how and when to repeat the dose, and which household members to treat. Weight-based doses such as oral ivermectin, pyrantel and griseofulvin are calculated when a weight is entered.
School guidance follows the Red Book and AAP: no exclusion for head lice or pinworm and no-nit policies discouraged, return after the first scabies treatment, and school attendance once tinea treatment has started.
No. The AAP advises that the child can stay until the end of the day and start treatment that evening. No-nit policies are discouraged.

The child and all household and close contacts, at the same time, even if they have no symptoms. Itching can last 2 to 4 weeks after successful treatment.
No. Scalp ringworm needs oral therapy, usually griseofulvin or terbinafine for at least 6 weeks. Medicated shampoo is an add-on that lowers spread.
