Derbac M is an insecticide. It comes in liquid form so you can easily apply it to your scalp and deal with head lice. It’s an effective treatment for head lice, and it’s sometimes used for pubic lice and scabies infestations.
Head lice are very common, especially in young children and their families. Derbac M can effectively kill both the lice and their eggs, to stop them from coming back. Because it’s not a daily treatment and you don’t need to rinse your hair afterwards, it’s convenient too.
How does Derbac M work?
Derbac M contains 0.5% of the active ingredient malathion. Malathion is a type of insecticide medication. It’s one of a group of insecticides called acetylcholinesterase inhibitors, that work by blocking the action of the enzyme cholinesterase.
Head lice, pubic lice, scabies and other parasites need the cholinesterase enzyme to survive and reproduce. So the malathion in Derbac M quickly suffocates the insects, killing them and stopping their eggs from growing into adult lice.
What doses of Derbac M are there?
Derbac M comes as a liquid with 0.5% of malathion. You just use enough to cover your whole scalp, and you’re done. Usually, you’ll only need to apply it to your scalp once a week for two weeks, or until the lice are gone. You generally shouldn’t use Derbac M for more than three weeks.
If the head lice are still there after three weeks, go back to your clinician for advice. If you’re using our service, you can just message us through your account and we’ll help you out. Make sure to treat everyone in your household, so you don’t get another infestation after you’ve been treated.
When we present you with stats, data, opinion or a consensus, we’ll tell you where this came from. And we’ll only present data as clinically reliable if it’s come from a reputable source, such as a state or government-funded health body, a peer-reviewed medical journal, or a recognised analytics or data body.

How to use Derbac M
Follow your clinician’s advice when using Derbac M to get the best possible results. There are also some general tips for using it.
Apply Derbac M to dry hair and make sure that you cover your whole scalp with the liquid
Spread the liquid evenly from the roots to the tips of your hair
Let your hair dry naturally. Make sure the room is well ventilated, as Derbac M can have a strong smell
Wait for 12 hours, or overnight, before you shampoo your hair
Avoid open flames while the solution is in your hair, as it’s very flammable
Rinse your hair after shampooing and use a nit comb to remove all the dead lice and eggs
Repeat this process after seven days
How long does it take Derbac M to work?
Derbac M usually gets rid of head lice and their eggs in two weeks, and you only need to apply it once a week. Many of the lice and eggs should be removed with the first application of Derbac M.
But if you’ve been using it for three weeks and you still have head lice, speak to your clinician. You can also log into your account and message our clinicians if you ordered from us. We can give you advice on what to do next, and offer different solutions for head lice.
What should I do if I make a mistake when using Derbac M?
If you forget to use Derbac M when you’re supposed to, just apply it when you remember. It’s important to make sure you don’t get any in your eyes, as it may sting. You can make sure you avoid this by covering your eyes while you apply Derbac M. If you accidentally do get some in your eyes, rinse them with plenty of clean water.
Derbac M isn’t highly toxic, but to be safe you should seek immediate medical attention if you swallow some by accident. Try to avoid getting it near your mouth and nose when applying. Don’t use it if you have broken skin on your scalp.

FAQ: Derbac M
Have something specific you want to know? Search our info below, or ask our experts a question if you can’t find what you’re looking for.
How effective is Derbac M?
Answer:
Derbac M is considered an effective treatment for head lice. One study, in particular, found that Derbac M provides a 98% cure rate and a higher effectiveness rate compared to other treatments such as Nix creme rinse, which has 1% of the active ingredient permethrin.
Also, many of the people who participated in this study had their head lice disappear after one treatment, which shows Derbac M gets rid of lice fast. There was a 0% reinfestation rate among the people who were given Derbac M. So it’s a treatment for head lice that really works.
ow is Derbac M different from other treatments for head lice?
Answer:
Derbac M is a liquid that you apply to your scalp without the need to rinse it afterwards. While you leave Derbac M in your hair, there are also head lice shampoo treatments which you need to wash your hair after using them, like Lyclear. Lyclear uses a different active ingredient to Derbac M, called permethrin. It’s entirely up to you which method you prefer.
Derbac M is the only head lice treatment that contains the active ingredient malathion. If you’re sensitive to the malathion in Derbac M, Hedrin solution might also be a good option for you. It contains dimeticone, which isn’t an insecticide. It’s usually recommended for pregnant or breastfeeding women, and it works by suffocating the lice and disrupting their ability to regulate water.
Do I need a prescription for Dermac M?

You can’t buy Derbac M over the counter, but you also don’t need a prescription to get it. Derbac M is a pharmacy medicine, meaning that you will need to get it from a licensed clinician in a registered pharmacy.
