DetailsDerbac M Liquid is used for the eradication of head lice, pubic lice, and their eggs and also treats scabies. Malathion has been used to treat head lice since the 1960's. It acts by disrupting the metabolic processes of the lice and killing them. It is suitable for children from the age of 6 months as well as sufferers of asthma and those with sensitive skin.
Active ingredient: Malathion 0.5% w/w Derbac-M Liquid also contains the following inactive ingredients: Methyl Hydroxybenzoate, Propyl Hydroxybenzoate, Lanette Wax SX, Potassium Citrate, Citric Acid, Perfume HT 52, Water.
UsageTreatment of Head Lice: Apply sufficient Derbac-M liquid to dry hair to ensure that no part of the scalp is left uncovered. Work Derbac-M into the hair spreading the liquid from the roots to the tips. Leave the hair to dry naturally in a warm but well-ventilated room. After 12 hours, or the next day, if preferred, shampoo hair in the normal way. Rinse the hair and comb whilst wet to remove dead lice and eggs (nits).
Treatment of Crab (Pubic) Lice: Apply Derbac-M Liquid to the entire skin surface. Pay particular attention to all hairy areas including beards and moustaches. Avoid any other areas above the neck. Leave on for at least one hour before washing but preferably Derbac-M Liquid should be left on overnight. Wash off in the usual way.
Treatment of Scabies: Apply Derbac-M Liquid to the entire skin surface. In adults it may not be necessary to apply Derbac-M Liquid above the neck but children under the age of 2 years should have a thin film of Derbac-M Liquid applied to the scalp, face and ears, avoiding the eyes and mouth.
Do not wash Derbac-M Liquid off, or bathe for 24 hours. If hands or any other parts must be washed during this period, the Derbac-M Liquid treatment must be reapplied to those areas immediately.
Family members and close contacts should also be treated with Derbac-M Liquid simultaneously.
WarningsNot to be used on infants less than 6 months except on medical advice. Avoid contact with the eyes. Keep out of the reach of children. Continued prolonged treatment with this product should be avoided. It should be used not more than once a week and for not more than 3 consecutive weeks.
