Benzoic Acid + Salicylic Acid: Brands, Price & Uses in Bangladesh

Benzoic Acid + Salicylic Acid is a topical antifungal-keratolytic combination indicated for the treatment of superficial fungal (dermatophyte) infections of the skin.

Established/traditional uses

• Tinea pedis (athlete's foot)
• Tinea corporis (ringworm of the body)
• Tinea cruris (jock itch)
• Other superficial dermatophytoses with associated scaling/hyperkeratosis where a combined keratolytic-antifungal action is appropriate

Benzoic Acid + Salicylic Acid works by combining a mild topical antifungal (benzoic acid) with a keratolytic agent (salicylic acid) that helps soften and remove thickened, scaly skin, improving penetration of the antifungal component. Evidence for this combination comes from long-standing clinical and pharmacopoeial use (classically known as Whitfield's ointment) rather than large modern randomized trials, so it is generally regarded as a low-cost, first-line option for mild, uncomplicated superficial fungal skin infections rather than a substitute for prescription antifungals in extensive, resistant, or nail/scalp infections.

Adults and adolescents

Pediatric use

Use in infants and young children only under medical supervision, applied sparingly to a limited area, due to an increased risk of salicylate absorption (see Use in Special Populations).

Renal/hepatic impairment

No specific dose adjustment is established for topical use as directed; however, patients with renal or hepatic impairment should avoid extensive or prolonged application because of a theoretically increased risk of systemic salicylate accumulation.

General directions

• For external use on the skin only.
• Clean and dry the affected area before application.
• Continue treatment for the duration advised by the physician, typically 2–4 weeks, and for a few days after visible symptoms resolve to reduce the chance of recurrence.
• If no improvement is seen within 2–4 weeks, or if the condition worsens, consult a physician.

Most side effects of Benzoic Acid + Salicylic Acid are local and mild:

• Transient burning or stinging sensation on application
• Local skin irritation, redness, or dryness
• Peeling or scaling of treated skin (an expected keratolytic effect)
• Contact dermatitis or allergic skin reaction (uncommon)

Rare/serious: With excessive application, use over large body surface areas, prolonged use, or use under occlusion — particularly in infants and children — systemic absorption of salicylate can occur, leading to salicylism (salicylate toxicity), with symptoms such as tinnitus, hyperventilation, nausea, vomiting, dizziness, confusion, or, rarely, metabolic disturbances. Discontinue use and seek medical attention if such symptoms occur (see Overdose Effects).
