Hansaplast Hornhaut-Pflaster (Salicylic Acid)

Hansaplast Hornhaut-Pflaster is indicated for the localized removal of hyperkeratotic skin lesions, such as corns and calluses, where a keratolytic action can soften the thickened tissue before gentle debridement.

• Corns on the toes or plantar foot that cause discomfort while walking.
• Calluses on the heel or ball of the foot that develop from repeated pressure.
• Small hyperkeratotic patches on the hands or fingers due to manual work.
• Localized thickening on knees or elbows where skin is exposed to friction.
• Minor callus areas from ill‑fitting shoes that can be softened before grooming.

Topical application of salicylic acid may cause local skin reactions; most are mild and reversible, while rare events can be more concerning. These effects are generally limited to the area where the patch is placed and resolve after discontinuation.

Common

• Mild redness or erythema at the site of the patch.
• Light skin peeling or flaking as the keratin breaks down.
• Temporary itching, tingling, or burning sensation during the first few hours.
• Minor swelling that subsides within a day.

Serious

• Severe irritation or contact dermatitis with intense redness.
• Allergic response such as swelling, hives, or blister formation.
• Persistent pain, ulceration, or tissue breakdown requiring medical attention.

Before using Hansaplast Hornhaut-Pflaster, consider several safety measures to minimize irritation and ensure appropriate use.

• Do not apply the patch to broken, infected, or inflamed skin.
• Avoid use on sensitive areas such as the genitals, mucous membranes, or open wounds.
• Keep the patch away from eyes and avoid contact with the eyes.
• Do not exceed the recommended duration of contact; remove the patch as instructed.
• Discontinue use and seek medical advice if severe irritation or an allergic reaction develops.
• Pregnant or breastfeeding individuals should consult a healthcare professional before use.
• Children under 12 years of age should use the product only under adult supervision.

Salicylic acid can interact with other topical agents or systemic medications; awareness of potential interactions helps avoid adverse effects.

Avoid

• Concurrent use of other keratolytic or exfoliating products (e.g., glycolic acid, urea) on the same area.
• Application together with topical retinoids or corticosteroids without professional guidance.
• Use on skin treated with chemical peels or laser therapy.

Use with caution

• Systemic salicylate‑containing drugs (e.g., aspirin) in patients with salicylate sensitivity.
• Patients with renal or hepatic impairment who may have altered salicylate metabolism.
• Individuals taking anticoagulant therapy, as salicylates can affect platelet function.
