While no single treatment guarantees 100% permanent lice eradication with a single application for everyone, certain medications are highly effective at killing lice and their eggs, often requiring just one or two treatments when used correctly.
Here's a breakdown of medications known to be effective against lice:
-
Ivermectin (Sklice): This lotion is often effective in a single application, killing both live lice and newly hatched lice.
-
Malathion (Ovide): A stronger lotion that paralyzes and kills lice, as well as some lice eggs. Due to its strength, follow instructions carefully.
-
Spinosad (Natroba): Another effective topical medication for killing lice and their eggs.
Important Considerations:
- Resistance: Lice can develop resistance to certain medications. If a treatment doesn't work, consult with a doctor or pharmacist about alternative options.
- Application: Follow the product instructions exactly for optimal effectiveness. This includes applying the medication thoroughly to the scalp and hair, and leaving it on for the recommended time.
- Nit Removal: While some medications kill lice eggs (nits), manual removal of nits can help prevent re-infestation. Use a fine-toothed comb designed for nit removal.
- Environmental Treatment: While less critical than treating the infested individual, washing bedding, clothing, and hats in hot water and drying on high heat can help eliminate any lice or nits that may have fallen off. Items that can't be washed can be dry-cleaned or sealed in a plastic bag for two weeks.
- Retreatment: Depending on the medication and the severity of the infestation, a second treatment may be necessary 7-10 days after the first to kill any newly hatched lice.
