Derbac M Liquid - 150ml

Derbac M Liquid - Effective Head Lice Treatment Solution

 

You can rely on Derbac M liquid to treat head lice and scabies infestations effectively. This medicated lotion contains malathion, an organophosphate insecticide that works by disrupting the nervous system of lice and mites. The 150ml bottle provides sufficient treatment for most infestations, making it suitable for both children and adults when used as directed.

The aqueous formulation ensures the active ingredient penetrates effectively whilst being gentler on your scalp compared to alcohol-based alternatives. You should apply this treatment to dry hair and scalp, ensuring complete coverage of all affected areas for optimal results.

 

How Malathion Eliminates Lice and Scabies

 

Malathion works by inhibiting acetylcholinesterase, an enzyme essential for proper nerve function in insects and mites. When you apply the lotion, it penetrates the exoskeleton of lice and scabies mites, causing paralysis and death. This mechanism of action makes it effective against both adult parasites and their eggs.

The treatment requires contact time of at least 12 hours for head lice and 24 hours for scabies to ensure complete elimination. You should leave the lotion on overnight and wash it off the following morning with ordinary shampoo and warm water.

 

Who Should Use This Head Lice Treatment

 

This malathion lotion suits most people over 6 months of age who have confirmed head lice or scabies infestations. You can use it safely during pregnancy and breastfeeding when other treatments may not be suitable. The aqueous base makes it particularly appropriate if you have sensitive skin or respiratory conditions that make alcohol-based products unsuitable.

The treatment is effective for:

• Active head lice infestations in children and adults
• Scabies mites affecting any part of the body
• Cases where other treatments have failed
• Situations requiring a non-alcohol based solution

For comprehensive scalp and hair care needs, you may want to consider additional products to maintain healthy hair after treatment.

 

Why Choose Aqueous-Based Formulation

 

The water-based formulation offers several advantages over alcohol-based alternatives. You experience less scalp irritation and reduced risk of skin drying, making it more comfortable during the extended contact time required. The aqueous base also eliminates fire hazard concerns associated with alcohol-containing products.

This formulation spreads more evenly through your hair and remains stable on the scalp without evaporating quickly. The reduced odour compared to other insecticidal treatments makes it more tolerable for extended wear, particularly important given the overnight application requirement.

 

Storage and Clinical Considerations

 

You should store this medicine below 25°C and keep it away from children when not in use. The lotion remains stable for the duration of its shelf life when stored correctly. Always check the expiry date before use and dispose of any remaining product safely after treatment completion.

Clinical studies demonstrate malathion's effectiveness against organophosphate-resistant lice strains, making it a reliable second-line treatment option. You should avoid contact with eyes and mucous membranes during application, and ensure adequate ventilation in the treatment area.
