How to get rid of eyelash louse? - briefly
Treat the infestation with a 1 % permethrin or pyrethrin lotion applied to the eyelashes, leave for the recommended period, then rinse and clean the area; repeat after 7–10 days to eliminate newly hatched nits. Remove any visible eggs with fine tweezers and launder bedding, towels, and personal items to prevent re‑infestation.
How to get rid of eyelash louse? - in detail
Eyelash lice (Phthiriasis palpebrarum) are tiny parasitic insects that attach to the base of the eyelashes, causing irritation, itching, and possible secondary infection. Effective eradication requires accurate identification, prompt mechanical removal, appropriate topical medication, and strict hygiene measures.
The first step is confirmation of infestation. Visual inspection with a magnifying lens reveals live nits attached to the hair shaft and adult lice moving among the lashes. If uncertainty remains, a dermatologist or ophthalmologist can perform a slit‑lamp examination and collect specimens for microscopic analysis.
Mechanical removal eliminates the majority of parasites. Use fine‑point tweezers or a disposable eyelash comb to grasp each louse and pull it outward from the root. Perform the procedure in a well‑lit area, repeat the process for both eyes, and dispose of extracted insects in sealed containers. Follow with a thorough cleaning of the comb or tweezers in 70 % isopropyl alcohol.
Topical agents complement manual extraction. Apply one of the following, according to severity and tolerance:
- 1 % permethrin cream: apply to the lid margin, leave for 10 minutes, then rinse with sterile saline. Repeat after 24 hours.
- 0.5 % malathion lotion: apply with a cotton swab, avoid direct contact with the globe, leave for 8 hours, then wash off. Use only under medical supervision.
- 1 % ivermectin ophthalmic solution (prescription): instill one drop in each eye twice daily for three days.
Systemic oral ivermectin (200 µg/kg) may be prescribed for extensive infestations or when topical therapy fails. Monitor for adverse reactions and ensure the patient is not pregnant or lactating.
Hygienic measures prevent reinfestation:
- Wash all bedding, towels, and clothing in hot water (>60 °C) and dry on high heat.
- Disinfect personal items such as makeup brushes, eyelash extensions, and contact lenses with appropriate antiseptics.
- Avoid sharing cosmetics or eye-care tools.
- Maintain regular eyelid hygiene using a mild, non‑oil cleanser twice daily for one week after treatment.
Follow‑up examination 7–10 days after the final treatment confirms eradication. Persistent nits or recurrent symptoms warrant repeat mechanical removal and a second course of topical medication. Early and comprehensive intervention eliminates the parasite, alleviates discomfort, and reduces the risk of secondary complications.
