Adult Dosing Guidelines

  • For treatment of lice infestation, wash hair with mild shampoo and dry. Apply Rid to hair until it is thoroughly wet and wait at least 10 minutes, preferably 15-20 minutes. Add sufficient amount of warm water to the hair to make a lather and then rinse. Use a nit comb to remove dead lice and nits. Retreat after 7-10 days since no product is ovicidal.

 Pediatric Dosing Guidelines

Topical absorption is poor, so there is no specific age cut off but the general guideline of 2 years of age applies. Due to the large surface area of the head of a child or infant, a physician should be consulted.
