Derbac-M Liquid kills head lice, crab (pubic) lice, and scabies mite.

Derbac-M Liquid is a gentle treatment ideal for use where asthma or sensitive skin is a problem.

The active ingredient of Derbac-M is malathion 0.5% w/w, an insecticide that kills parasites by effecting their metabolic processes.

Derbac-M Liquid is suitable for adults, the elderly and children aged 6 months and above. Infants under six months should only be treated with Derbac-M Liquid under medical supervision.

Directions:

• Treating head lice
  Apply sufficient Derbac-M liquid to dry hair to ensure that no part of the scalp is left uncovered. Work the liquid into the hair spreading the it evenly 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).
  • Treating crab lice (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 for best results it should be left on overnight. Wash off in the usual manner.
  
  
  • Treating scabies
    Apply Derbac-M Liquid to the entire skin surface. In adults it may not be necessary to apply 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 treatment must be reapplied to those areas immediately.
    Family members and close contacts should also be treated simultaneously.
