💊 Adverse Effects and Precautions

Salicylic acid is a mild irritant and application of salicylic acid preparations to the skin may cause dermatitis. Preparations containing high concentrations of salicylic acid can cause skin ulceration or erosion; healthy skin surrounding warts, corns, and calluses should be protected with soft paraffin or specially designed plasters when such preparations are being used. Salicylic acid should be used with care on the extremities of patients with impaired peripheral circulation or diabetes; caution has also been suggested if caustic preparations are used in patients with significant peripheral neuropathy. The drug is readily absorbed through the skin, and symptoms of acute systemic salicylate poisoning have been reported after excessive use; deaths have occurred, mainly in children. To minimise absorption after topical application salicylic acid should not be used for prolonged periods, in high concentrations, on large areas of the body, or on inflamed or broken skin. Contact with mouth, eyes, and other mucous membranes should be avoided.

💊 Uses and Administration

Salicylic acid has keratolytic properties and is applied
topically in the treatment of hyperkeratotic and scaling skin conditions such as dandruff and seborrhoeic dermatitis, ichthyosis, psoriasis, and acne. Preparations usually contain between 2 and 6% salicylic acid, but a wider range of concentrations has been used. It is often used with other drugs, notably coal tar. Preparations containing up to 60% salicylic acid have been used as a caustic for the removal of plantar warts, corns, or calluses; surrounding healthy skin should be protected (see above). Salicylic acid also possesses fungicidal properties and is used topically in the treatment of dermatophyte skin infections; propyl salicylate and bromosalicylic acid have been used similarly. Zinc salicylate has been used similarly to salicylic acid in the treatment of seborrhoeic dermatitis and acne.
