Skin and subcutaneous tissue disorders:

Treatment should be discontinued if severe irritation occurs.

Symptoms

In cases of accidental ingestion, acute intoxication symptoms may be observed such as nausea, vomiting and irritation of the buccal, oesophageal and gastric mucosa. Rare cases of loss of consciousness and seizure were reported. General measures to eliminate the drug and reduce its absorption should be undertaken.

Symptomatic treatment should be administered as appropriate. Moreover although very rare, risk of methaemoglobinaemia exists in case of accidental ingestion as well as in case of excessive cutaneous absorption.

Management

The symptoms usually disappear following the discontinuation of the drug, but in severe cases treatment with methylene blue may be considered.

Pharmacotherapeutic group: other antipruritics (ATC code D04AX).

Crotamiton has a symptomatic action on pruritus and is an acaricide. As an acaricide agent, crotamiton is effective on the motor system of the mites by inducing irreversible cessation of spontaneous movements.

Cronix/Boots Dermacare Itch Relief Lotion will provide relief from irritation for 6 - 10 hours after each application.

Cronix/ Boots Dermacare Itch Relief Lotion penetrates rapidly into human skin. Low but measurable concentrations of crotamiton are found in plasma, with a maximum level after 4-10 hours, declining rapidly thereafter.

Preclinical data do not show teratogenic nor genotoxic risk for crotamiton. Cronix/Boots Dermacare Itch Relief Lotion administered dermally topically once daily under occlusive dressing for 3 months to rabbits was tolerated at doses of up to 200 mg/kg without signs of toxicity, apart from transient skin irritation.

No sensitising or photo-sensitising potential has been observed in animal studies.

None.

Medicines should be kept out of the reach and sight of children.
