What is Derbac M

Effective treatment of head lice is necessary to prevent their spread, and there are several products available to eradicate them. One such product is Derbac M Liquid which has an active ingredient proven to kill the lice and their eggs when used as directed. It is also an effective treatment for pubic lice and scabies.

Head lice and their eggs are also known as nits and are most commonly found in young children who catch them due to being in close proximity to someone else who has them. They can easily jump from head to head, making the problem very difficult to avoid and easy to spread when mixing with other children. The lice are tiny insects which will cling to the hair and lay their eggs in it and on the scalp. 

How effective is Derbac M liquid?

Derbac M Liquid is exceptionally effective at entirely eradicating head lice with a single treatment thanks to its active ingredient, malathion. This product will ensure all head lice, eggs, pubic lice and scabies mites are killed within 12 hours so that they can be removed from the hair and scalp.

Malathion has been clinically proven as an active ingredient to treat these conditions and is safe enough to use in children as young as 6 months old.

Always follow the instructions for use, which will be provided within the product packaging.

How to use Derbac M liquid?

Derbac M Liquid can be used to treat head lice, pubic lice and scabies. Application of the product varies slightly depending on the infestation being treated:

Derbac M liquid to treat head lice

Apply the product all over the hair and scalp to ensure no part is uncovered. Hair must be dry before application. To make the process easier (and particularly with long hair), part the hair into small sections and apply the product to the scalp and from the root of the hair right to the ends.

Work the product fully into the scalp and hair to cover it completely.

Leave the hair to dry naturally (do not use a hairdryer) in a warm but well-ventilated room. The next day, or after 12 hours, shampoo the hair as you would normally, rinse it with plenty of clean water and comb it with a fine-toothed comb to remove the dead lice and their eggs.

Derbac M liquid to treat pubic lice

Apply the product over the entire surface of the skin, paying particular attention to any hairy areas, including beards and moustaches but on no other areas above the neck. Keep the product on for a minimum of one hour but preferably overnight before washing off, as you would normally cleanse yourself.

Derbac M liquid to treat scabies

Again, apply the product to the entire surface of the skin, including the areas above the neck, scalp, face and ears in children under 2 years old. In older children and adults, this might not be necessary. Always avoid the eyes and mouth.

Leave the Derbac M Liquid in place for 24 hours – do not wash it off. If you do need to wash any body parts within this timeframe, such as the hands, reapply more product immediately after. Once the 24-hour period is over, wash off as normal.

All members of the same family and close contacts should be treated with Derbac M Liquid simultaneously.

Warnings and cautions

As with any medicated skin treatment, there can be certain cases of side effects, and these are often as a result of an allergy or hypersensitivity to one of the ingredients. Although they are rare, they include:

  • Skin irritation
  • Severe allergic reactions (which could include difficulty breathing, dizziness and swelling of the face, throat and eyes)
  • Chemical burns

If any such side effects occur, discontinue use of the product immediately.

Derbac M Liquid is suitable for use on all children over the age of 6 months old and adults. Seek medical advice for the treatment of lice and scabies for children under 6 months.

Do not use if you are allergic to the ingredients which are:

  • Malathion 0.5% w/w
  • Methyl Hydroxybenzoate
  • Propyl Hydroxybenzoate
  • Lanette Wax SX
  • Potassium Citrate
  • Citric Acid
  • Perfume HT 52
