Permethrin belongs to a class of synthetic pyrethroids that act as insect-killing agents. It is widely used on the skin and scalp to eliminate tiny parasites that cause uncomfortable itching and skin irritation. In the UK, permethrin is the active component of several over-the-counter and prescription products such as Elimite, Acticin and the generic preparation simply called Permethrin.
A number of UK-available treatments include permethrin as the key ingredient. Elimite is marketed as a 1 % cream for the treatment of scabies, while Acticin is a 5 % lotion aimed at head lice. The generic Permethrin cream or spray can be found in a range of strengths, often supplied by pharmacy chains or online retailers. These products come as creams, lotions, or sprays that are applied to the skin or hair and left for a short period before washing off. Both brand-named and generic versions are authorised by the Medicines and Healthcare products Regulatory Agency (MHRA) and follow the same safety standards.

When applied to the skin or hair, permethrin interferes with the nerve signals of insects and mites. It keeps the tiny organisms from moving normally, leading to rapid paralysis and death. Because the effect is local and does not rely on absorption into the bloodstream, the action begins within minutes after application and continues while the product remains on the surface.

For a complete list of possible interactions, refer to the information leaflets that accompany each specific product.
Store permethrin preparations in a cool, dry place away from direct sunlight and out of reach of children. Most treatments are intended for short-term use, either a single application for lice or a brief course for scabies. Always read the product label for details about how long to leave the cream or lotion on the skin. Remember, the exact instructions can differ between Elimite, Acticin and generic Permethrin, so follow the directions that come with the product you are using.
