Not relevant to cutaneous use

Pregnancy:

There is no data on the use of topical salicylic acid in pregnant women. Therefore the use of this product during pregnancy is contraindicated.

Breast feeding:

Salicylates should be given with caution to breast-feeding mothers because of the possible risk of Reye's syndrome in nursing infants and there is no data on the use of topical salicylic acid in breast feeding women. Therefore the use of this product during pregnancy is contraindicated.

Fertility:

There is no information on the effects of topical salicylic acid and fertility.

None stated

Local irritation or dermatitis may occur if applied to normal healthy skin surrounding the wart. This may be controlled by temporarily discontinuing use and by carefully applying only to the wart when the treatment is resumed.

Salicylic acid is readily absorbed through the skin, and symptoms of acute systemic salicylate poisoning have been reported after excessive use. Symptoms include dizziness, tinnitus, deafness, sweating, nausea and vomiting, headache, and confusion, and may be controlled by reducing the dosage.

Keratolytics

Mechanism of Action

The mechanism of action of salicylic acid has not been established.

Pharmacodynamics Effects

Salicylates have analgesic, anti-inflammatory and antipyretic properties, much of which is ascribed to an inhibition of prostaglandin synthesis. However, the relevant pharmacodynamic effect of salicylic acid for this product is its “keratolytic” action. The mechanism of this effect has been investigated in animals and in man, and appears to be due to a reduction of intercellular cohesion and/or increasing endogenous hydration. The exact mechanism of action however has not yet been elucidated.

Salicylic acid can be absorbed following topical application. Plasma salicylate is largely protein-bound and is metabolised by oxidation and conjugation with some excreted unchanged. The elimination of salicylate follows first order kinetics with a half-life of about four hours except with high systemic doses which result in saturation of the elimination mechanism.

Salicylic acid has a low acute toxicity with oral LD₅₀ values of 480mg/kg in the mouse and 891 mg/kg in the rat. It is a dermal irritant but systemic toxicity from application of Scholl Verruca Removal System is extremely unlikely because of the small quantities applied.
