Derbac-M 0.5% Liquid - 150ml

Derbac-M is a medicated lotion used for the treatment of head lice (Pediculus humanus capitis) and their eggs (nits). In this comprehensive guide, we will provide you with detailed information about Derbac-M, including its description, directions for use, ingredients, potential side effects, and important warnings.

Derbac-M contains the active ingredient malathion, which is an organophosphorous compound that effectively kills head lice and their eggs. It is widely recognized as a safe and effective treatment for head lice infestations in both adults and children.

Proper application of Derbac-M is crucial for its effectiveness and safety. Follow these directions for use:
Shake the Bottle: Before use, shake the bottle well to ensure that the lotion is thoroughly mixed.
Apply to Dry Hair: Start by applying Derbac-M to dry hair. Ensure that the hair is completely dry before application.
Dispense the Lotion: Dispense a sufficient amount of lotion onto the hair, focusing on the roots and scalp. The amount needed depends on the length and thickness of the hair, so follow the instructions provided with the product.
Thoroughly Massage In: Gently and thoroughly massage the lotion into the hair and scalp. Pay special attention to the areas behind the ears and at the nape of the neck, as lice and nits often cluster in these regions.
Leave for Recommended Time: Leave the lotion on the hair and scalp for the duration specified in the product instructions. This typically ranges from 12 to 24 hours, but it can vary depending on the product.
Rinse and Comb: After the recommended time has passed, wash the hair with a mild shampoo and rinse thoroughly. While the hair is still wet, use a fine-toothed comb to remove any dead lice and nits. This step is crucial for ensuring the removal of lice and their eggs.
Repeat if Necessary: In some cases, a second application of Derbac-M may be required after 7 days to ensure complete elimination of lice and nits. Follow the instructions provided with the product for guidance.
Wash Bedding and Clothing: Wash or dry-clean all bedding, clothing, and personal items that may have come into contact with the infested person's hair. This helps prevent reinfestation.
