Side Effects & Adverse Reactions
The benzoic acid can be irritant to the skin, eyes and mucous membranes. Salicylic acid is a mild irritant and application to the skin may cause dermatitis. Quick absorption of salicylic acid through the skin and slow excretion in the urine may cause acute systemic salicylate poisoning after excessive application of salicylic acid to large areas of the body.
Warnings & Precautions
It is only for external use. Care should be taken to keep the product away from contact with the mouth, the eyes and other mucous membranes to avoid irritation. It should be used with care on the extremities of patients with impaired peripheral circulation and diabetes. Skin irritation may develop. If undue skin irritation develops or increases, the patient should adjust the dosage schedule or consult their physician.
Pharmacology & Mechanism of Action
This contains Benzoic Acid and Salicylic Acid in a ratio of 2:1 (6%:3%) which is also known as Whitfield's ointment. It combines the fungistatic action of benzoic acid with the keratolytic action of salicylic acid. Since benzoic acid is only fungistatic, eradication of the infection occurs only after the infected stratum corneum is shed, and continuous medication is required for several weeks to months. The salicylic acid accelerates the desquamation.
