Witty

Witty Uses, Dosage, Side Effects, Food Interaction and all others data.

Witty induces electrochemical abnormalities across the membranes of excitable cells, leading to sensory hyperexcitability, in coordination and prostration. Witty is rapidly metabolized in mammals by ester hydrolysis to inactive metabolites which are excreted primarily in the urine. The principal metabolites of Witty are detectable in the urine within hours of a whole body application of the cream to healthy volunteers or scabies patients. The highest levels of excretion are detectable within the first 48 hours, but very low levels of metabolites are still detectable in the urine of some individuals 28 days after treatment.

Witty, a pyrethroid, is active against a broad range of pests including lice, ticks, fleas, mites, and other arthropods.

Side Effects

In scabies patients, skin discomfort, usually described as burning, stinging or tingling occurs in a few individuals soon after the cream is applied. Other transient signs and symptoms of irritation including erythema, edema, eczema, rash and pruritus which may follow the treatment of scabies with Witty are generally considered to be the part of the natural history of scabies. In patients treated for scabies, itching may persist for up to 4 weeks post-treatment. This is generally regarded as due to an allergic reaction to the dead mites under the skin and is not necessarily indicative of a treatment failure.

Toxicity

Oral, rat LD50: 430 - 4000 mg/kg; skin, rabbit LD50: 2000 mg/kg.

Precaution

Witty is not an eye-irritant, but the cream itself may cause marked irritation. Nursing staff who routinely apply Witty, may wear gloves to avoid any possible irritation to the hands.

Interaction

The treatment of eczematous-like reactions with corticosteroids should be withheld prior to treatment with Witty, as there is a risk of exacerbating the scabies infestation by reducing the immune response to the mite.

Food Interaction

No interactions found.

Elimination Route

Poorly absorbed through the skin.

Elimination Route

Witty is rapidly metabolized by ester hydrolysis to inactive metabolites which are excreted primarily in the urine.

Pregnancy & Breastfeeding use

There are limited data on the use of Witty in pregnancy which provide no indication of any risk to the foetus. Furthermore, the amount of Witty absorbed systemically following a whole body application is extremely low. The negative mutagenicity tests and the very low mammalian toxicity would suggest that any risk to the foetus following treatment with Witty is minimal. Inspite of these, Witty is suggested not to useduring pregnancy.
