Contents
Permethrin.
Description
An off white lotion containing Permethrin 5.0% w/v with Methyl Paraben 0.08% w/v and Propyl Paraben 0.02% w/v as preservatives.
Action
Permethrin acts on the sodium channel current that regulates the polarization of the nerve cell membrane of the louse or mite. This leads to delayed repolarization and subsequent paralysis of the louse or mite.
Pharmacology: Permethrin is a synthetic pyrethroid, which is active against a broad range of pests including lice, ticks, fleas, mites and other arthropods. Absorption studies indicants that 2% or less of the amount applied is absorbed systemically. Permethrin is detectable in residual amounts on the hair for at least 10 days following a treatment. Permethrin is rapidly metabolized by ester hydrolysis to inactive metabolites. It is primarily eliminated in the urine.
Indications/Uses
For the treatment of scabies.
Dosage/Direction for Use
Ensure that the skin is clean, dry and cool prior to treatment.
Adults & children: apply thoroughly to all body parts from the head to the soles of the feet, paying particular attention to all the folds and creases. Scabies rarely infests the scalp of adults, although the hairline, neck, temple and forehead may be infested in infants and geriatric patients. Leave medication on for 8 - 14 hours, and then wash off completely. Usually a 30 ml bottle is sufficient for any adult.
Infants under 2 months: not recommended.
One application is generally curative.
Persistent pruritus may be experienced after treatment. This is rarely a sign of treatment failure and is not an indication for re-treatment. Itching usually persists for a few days or even weeks after treatment even though the mite has been killed. This is because it takes time for the allergic reaction to subside.
Overdosage
No instance of accidental ingestion has been reported. If ingested, gastric lavage and general supportive measures should be employed.
Contraindications
Hypersensitivity to permethrin, any of its compounds, other synthetic pyrethrins.
