What is Natroba (spinosad) used for?
Natroba is a prescription medicine used to treat head lice (pediculosis capitis) in patients who meet the product’s approved age criteria. It contains spinosad, which kills lice.
How is Natroba applied?
Natroba is typically applied to dry hair and the scalp, then left on for the time specified in the prescribing information. After the treatment time, it is rinsed out. A second treatment may be needed based on how the product label directs retreatment for persistent lice.
What side effects do people report with Natroba?
Common side effects can include scalp and skin irritation (such as redness, burning, or itching). If symptoms worsen or a patient develops a severe allergic reaction, medical care is needed.
Is Natroba different from other head lice treatments?
Yes. Natroba (spinosad) is different from older options such as permethrin or pyrethrins, which work through different mechanisms and may be affected by lice resistance patterns. Choice of product can depend on prior treatments, local resistance, and patient factors.
How does spinosad work against lice?
Spinosad targets the nervous system of lice, leading to their death. This differs from pediculicides that primarily affect other biological pathways.

What should I do if Natroba doesn’t work?
If live lice are still present after treatment, patients usually need to follow the label’s instructions for retreatment and check for proper application. Persistent treatment failure may require switching to another approved therapy and confirming the diagnosis (for example, distinguishing live lice from nits/hair debris).
