What is the name of lice shampoo in a pharmacy? - in detail
Lice treatment shampoos sold in pharmacies are commonly identified by their active ingredient and brand name. The most widely available products contain permethrin (1 % concentration) and are marketed under names such as «Nix» and «Rid». Another popular option uses pyrethrins combined with piperonyl butoxide, found in «Rid» 2‑step kits. Dimethicone‑based shampoos, which act by coating and immobilising lice, appear under the label «LiceMD» and «LiceFreee». Malathion (0.5 %) is a prescription‑only preparation, distributed as «Ovide» in many regions.
Key characteristics to consider:
- Active ingredient – Determines efficacy against resistant lice strains; permethrin and dimethicone are first‑line choices, while malathion is reserved for resistant cases.
- Formulation – Shampoos may be liquid, foam, or spray; liquid forms require thorough scalp coverage, foam offers easier application, and spray facilitates targeting hard‑to‑reach areas.
- Dosage instructions – Typically applied to wet hair, left for 10 minutes, then rinsed; some products require a second application after 7‑10 days to eliminate newly hatched nits.
- Age restrictions – Permethrin shampoos are approved for children aged 2 months and older; dimethicone products often allow use from birth, but label specifications must be followed.
- Safety profile – Most over‑the‑counter options have minimal systemic absorption; adverse reactions may include scalp irritation or mild itching. Prescription malathion may cause skin irritation and should be used under medical supervision.
When selecting a pharmacy‑available lice shampoo, verify the active ingredient, review the age‑specific labeling, and follow the manufacturer’s timing schedule to achieve complete eradication.
