Head Lice Medication - Additional Information

What if the medication comes into contact with my child’s eyes?

Immediately wash the child’s eyes under a running tap for at least 15 minutes. If irritation, pain, swelling or tearing of the eyes persists, consult a doctor.

Do I need to clean the house?

Head lice do not survive long if they fall off a person and cannot feed, however to prevent re-infestation by lice, it is very important to wash in hot water all bedsheets, pillowcases, underwear, pyjamas and recently worn clothing (in the past 2 days before treatment) after completing the treatment and dry under direct sunlight or in a hot cycle dryer. Items that cannot be washed, e.g. large blankets, stuffed animals or dolls, should be put away in sealed plastic bags (away from contact) for 2 weeks. Combs and brushes are recommended to be soaked in hot water for 5 – 10 minutes. Vacuum the floor and furniture, particularly where the infested person sat or lay.​

Why is it still itch​ing after treatment?

Itching may occasionally worsen 1 to 2 days after treatment. It may also persist for 2 to 3 weeks after successful treatment which is normal and possibly due to the allergic reaction to the dead lice or nits. Your doctor may give you some medication to relieve the itch in the meantime.​

You may also visit a pharmacist to obtain some antihistamines for the itch. If the skin appears to be dry, consult your pharmacist for a moisturiser and milder soap.

If the itch does not go away by the fourth week after treatment, consult your doctor.
