Ichtholan (Ichthammol)

Ichtholan is a topical agent employed in dermatological conditions where inflammation, infection or keratolysis are present.

• Eczema: reduces inflammation, itching and redness.
• Psoriasis: helps soften plaques and control local inflammation.
• Boils and furuncles: provides antibacterial action and promotes drainage.
• Minor skin infections: assists in controlling bacterial growth on superficial lesions.
• Insect bites: soothes irritation and diminishes swelling.

• Ichthammol exerts its effects through a combination of anti‑inflammatory, antibacterial and mild keratolytic actions. The compound penetrates the stratum corneum, where it modulates inflammatory mediators, disrupts bacterial cell membranes, and promotes desquamation of hyperkeratotic tissue, thereby reducing redness, swelling and microbial load.

Topical application of Ichtholan may be associated with local skin reactions.

Common Side Effects

• Skin irritation: mild redness or discomfort at the application site.
• Dryness: transient loss of moisture on treated skin.
• Erythema: localized reddening that usually resolves.
• Burning sensation: brief warmth or tingling after use.

Serious or Rare Side Effects

• Allergic contact dermatitis: intense itching, swelling or blistering.
• Severe skin ulceration: uncommon deep lesions requiring medical attention.
• Systemic toxicity: rare absorption leading to systemic effects.
• Anaphylaxis: extremely rare, rapid-onset allergic reaction.

When using Ichtholan, consider the following safety measures.

• Avoid application on broken skin: limit use to intact epidermis unless directed by a clinician.
• Do not use on mucous membranes: keep away from eyes, mouth and genital areas.
• Discontinue if severe irritation occurs: seek medical advice promptly.
• Pregnancy and lactation: safety not established; consult a healthcare professional before use.
• Store at room temperature: keep in the original container, protect from moisture and direct sunlight.

Ichtholan may interact with other topical agents or dressings.

Major Interactions (Avoid)

• Concurrent use with strong topical irritants (e.g., alcohol‑based cleansers): may increase skin irritation.
• Application together with potent corticosteroids: may reduce the efficacy of either product.

Moderate Interactions (Monitor Closely)

• Use with occlusive dressings: can enhance percutaneous absorption.
• Co‑application with phototherapy: may increase photosensitivity.
• Combination with other keratolytic agents (e.g., salicylic acid): monitor for excessive peeling or irritation.
