Permethrin Medical Grade 5% w/w (cis:trans isomer 25:75) For excipients, see 6.1.
Cream for topical application.
Permethrin 5% w/w Cream is indicated for the treatment of scabies.
Permethrin 5% w/w Cream is suitable for adults, children of 2 months of age and above, and the elderly. Permethrin 5% w/w Cream is for external use only and should not be applied to broken skin, mucous membranes or near the eyes. Permethrin 5% w/w Cream should be applied to skin which is clean dry and cool. It should not be used immediately after a hot bath. Permethrin 5% w/w Cream is a vanishing cream and when rubbed gently into the skin it will disappear. Therefore, there is no need to continue to apply cream to the skin until it remains detectable on the surface. Reapply the cream to the hands if they are washed within 8 hours of treatment. The whole body should be washed thoroughly 8-12 hours after application. Children under 2 years should only be treated under medical supervision. Older children should be supervised when applying the cream to ensure that a thorough treatment is administered. In view of the great variability in body area and skin types, precise dosage recommendations are not possible. In cases where the head, neck, scalp and ears are treated (see below), the dosage may be increased to ensure total body coverage.
Adults & children over 2 years: Apply the cream over the whole body but NOT the head and face. Pay particular attention to the areas between fingers and toes, under nails, wrists, armpits, external genitalia, breasts and buttocks. The elderly: Apply the cream over the whole body INCLUDING the neck, face, ears and scalp. Pay particular attention to the areas between fingers and toes, under nails, wrists, armpits, external genitalia, breasts and buttocks. Avoid the area close to the eyes. Children under 2 years: Apply the cream over the whole body INCLUDING the neck, face, ears and scalp. Pay particular attention to the areas between fingers and toes, under nails, wrists, armpits, palms of hands and soles of feet, external genitals and buttocks. Avoid the area around the mouth where the cream could be licked off and the area around the eyes. Children should be kept from licking the cream from the hands. If necessary, children should wear gloves. Approximately 90% of individuals are cured after a single application. If there are no signs of the original lesions healing or if new lesions have appeared, a second application can be made not less than 7 days after the first application.
Permethrin 5% w/w Cream is contra-indicated in subjects with known hypersensitivity to the product, its components, other pyrethroids or pyrethrins.
Permethrin 5% w/w Cream should be kept out of the sight and reach of children. Permethrin 5% w/w Cream is for external use only. Nursing staff who routinely apply Permethrin 5% w/w Cream may wish to wear gloves to avoid any possible irritation to the hands. Carers who apply permethrin are advised to wear gloves. Permethrin is not an eye irritant but contact of Permethrin 5% w/w Cream with the eyes should be avoided because the cream itself may cause marked irritation. In the event of inadvertent eye contamination, the affected area should be rinsed immediately with plenty of water or, if readily available, normal saline. In the case of hypersensitivity to chrysanthemums or other compositae, treatment should only be given if strictly indicated. In such cases treatment should be switched to a chemically different agent. There is an increasing body of data specifically relating to the use of Permethrin 5% w/w Cream for the treatment of scabies in the elderly and in view of these data it is considered that there is no need for any special precautions for use in this age group. Healthcare professionals should be aware that if this product comes into contact with dressings, clothing and bedding, the fabric can be easily ignited with a naked flame. Patients should be warned of this risk and advised to keep away from fire when using this product. Paediatric population Only limited experience is available with Permethrin 5% w/w Cream in children aged 2 months to 23 months. Therefore treatment must be given only under close medical supervision in this age group. Excipients Permethrin creams contains 0.45g benzyl alcohol per tube. Benzyl alcohol may cause allergic reactions.
No interactions are known. The treatment of eczematous-like reactions with corticosteroids should be withheld prior to treatment with Permethrin 5% w/w Cream, as there is a risk of exacerbating the scabies infestation by reducing the immune response to the mite. The likelihood of interactions between the two treatments leading to potentiated adverse reactions or reduced efficacy is, however small.
The limited data available on the use of Permethrin 5% w/w Cream in pregnancy which provide no indication of any risk to the foetus. The amount of permethrin absorbed systemically following a whole body application is extremely low. However, some permethrin may pass the placental barrier. The negative mutagenicity tests and the very low mammalian toxicity suggest that there is minimal risk to the foetus following treatment with permethrin. It has been shown that very low concentrations of permethrin are excreted in milk following oral administration of permethrin in cattle. It is not known whether permethrin is excreted in human breast milk. However, because only extremely small amounts of permethrin are absorbed systemically and in theory only a very small percentage of this will pass into the breast milk, it is unlikely that the concentrations of permethrin in the milk will present any risk to the neonate/infant. Reproduction studies in mice, rats and rabbits given oral dosage of 200 to 400 mg/kg bodyweight/day revealed no evidence of impaired fertility. In addition permethrin did not show any adverse effects on the reproductive function of rats given an oral dosage of 180 mg/kg bodyweight/day in a three generation study. There was no evidence of teratogenicity in reproduction studies in mice, rats and rabbits.
In scabies patients, skin discomfort (paraesthesias), usually described as burning, stinging or tingling, occurs in a few individuals soon after Permethrin 5% w/w Cream is applied. This occurs more frequently in patients with severe scabies and is usually mild and transient. Other transient signs and symptoms of irritation, including erythema, oedema, eczema, rash and pruritus which may follow treatment of scabies with Permethrin 5% w/w Cream are generally considered to be part of the natural history of scabies. In patients treated for scabies, itching may persist for up to 4 weeks post-treatment. This is generally regarded as due to an allergic reaction to the dead mites under the skin and is not necessarily indicative of a treatment failure. Reporting of side effects If you get any side effects, talk to your doctor, pharmacist or nurse. This includes any possible side effects not listed in this leaflet. You can also report side effects directly via the Yellow Card Scheme at: www.mhra.gov.uk/yellowcard or search for MHRA Yellow Card in the Google Play or Apple App Store. By reporting side effects you can help provide more information on the safety of this medicine.
There are no reports of overdosage of Permethrin 5% w/w Cream. Application of a full tube (30 g) of cream to a 2-month old would result in a dose of approximately 350 mg/kg bodyweight. Even if 100% of the permethrin absorbed, this dose would be unlikely to cause overt signs of systemic toxicity. It is possible that excessive application of Permethrin 5% w/w Cream to the skin might result in localised adverse reactions or more severe skin reactions. Treatment of hypersensitivity-type reactions should be symptomatic. Symptoms of overdose may include nausea, headache, vomiting, dizziness and convulsion. In the event of accidental ingestion of the contents of a tube of Permethrin 5% w/w Cream by a child, gastric lavage should be considered if consultation is within 2 hours of ingestion.
The principal physiological action in susceptible parasites exposed to permethrin is induction of electrochemical abnormalities across the membranes of excitable cells, leading to sensory hyper-excitability, inco-ordination and prostration. It is assumed that the mode of action against arachnids (mites) is similar.
Permethrin is rapidly metabolised in mammals by ester hydrolysis to inactive metabolites which are excreted principally in the urine. The principal metabolites of permethrin are detectable in the urine within 7 hours of whole body application of the cream to healthy volunteers or scabies patients. The highest levels of excretion are detectable within 48 hours but very low levels of metabolite are still detectable in the urine of some individuals 28 days after treatment. The overall pattern of excretion indicates a mean of approximately 0.5% of applied permethrin is absorbed during the first 48 hours.
In vitro and in vivo genetic toxicity studies were all negative, revealing no potential for permethrin to induce mutagenic changes. In repeated long-term bioassays for carcinogenic potential performed in rats, no evidence of oncogenicity was observed. Similar studies in mice have shown species specific increases in pulmonary adenomas, a common benign tumour of mice of high spontaneous background incidence. In one of these studies, there was an increased incidence of benign liver adenomas and of pulmonary alveolar cell carcinomas only in female mice when permethrin was given in their food at 1:5000 parts per million (approximately 750 mg/kg bodyweight/day) for two years. It is considered that these findings do not indicate a significant oncogenic potential for permethrin in humans.
