Ask a pharmacist or healthcare professional if you are unsure which treatment is suitable or how to use it. Product labels can set different age limits, precautions and repeat-treatment schedules.
Seek professional advice before treatment when
- The person is a young child or falls below the age stated on the product label.
- The person is pregnant, breastfeeding, has a known allergy or has a scalp condition.
- The product has caused a concerning reaction or the scalp is severely irritated.
- Live lice appear to remain after correct use and the label does not explain what to do next.
- You are not sure whether the specks you see are lice, nits or dandruff.
Do not combine treatments or apply a dose early without advice. Never use household pesticides, fuel, bleach or other products that are not intended for human use.
For general information see the CDC’s head-lice treatment guidance. For emergencies or severe symptoms, contact local medical services.
