    Contra-indications, adverse effects, precautions

    • Use with caution and under medical supervision in children under 6 months.
    • May cause: scalp irritation, pruritus, skin rash and redness; rarely: oedema, hypersensitivity reactions.
    • Avoid contact with eyes. In case of accidental contact, flush immediately with plenty of water.
    • Pregnancy and breast-feeding: prefer dimeticone


    • Examine everyone in contact with a patient and only treat those with live lice and/or live nits. Preventive treatment of noninfected persons is ineffective and increases the risk of resistance.
    • Wash combs and decontaminate headwear and bedding: wash ≥ 60 °C, iron or dry in the sun or, if not feasible, seal in a plastic bag for 2 weeks. 
    • Use the lotion rather than the shampoo that is less effective as the contact time is usually shorter.
    • Permethrin 5% cream is used for the treatment of scabies in children 2 months and over and adults.
