Ictammolo Marco Viti (Ichthammol)

• Ichthammol is a topical anti‑inflammatory and antiseptic used for various dermatologic conditions.
• Acne: reduces inflammation and helps drainage of pustules.
• Eczema: alleviates itching and erythema.
• Boils and furuncles: facilitates spontaneous drainage and limits secondary infection.
• Insect‑bite dermatitis: soothes irritation and prevents bacterial overgrowth.

• Ichthammol contains sulfur‑rich organic compounds that penetrate the stratum corneum, exerting anti‑inflammatory effects by inhibiting leukocyte migration and cytokine release. Its mild antiseptic activity derives from the presence of phenolic and sulfonic acids, which reduce bacterial colonisation and promote wound drainage without systemic absorption.

Ichthammol is generally well tolerated when applied to intact skin, but local reactions may occur.

Common Side Effects

• Mild skin irritation or burning sensation at the application site.
• Dryness or peeling of the treated area.
• Transient erythema or redness.
• Pruritus (itching) that resolves with continued use.
• Contact dermatitis in sensitised individuals.
• Minor scaling or flaking.

Serious or Rare Side Effects

• Severe allergic reaction (anaphylaxis) requiring immediate medical attention.
• Extensive ulceration or necrosis of the skin.
• Systemic toxicity if applied to large broken areas over prolonged periods.
• Persistent infection despite treatment.
• Unexplained systemic symptoms such as fever or malaise.

• Before using Ichthammol, consider the following safety measures.
• Pregnancy: safety not established; use only if potential benefit justifies the risk.
• Breastfeeding: insufficient data; exercise caution.
• Skin integrity: avoid application on extensive open wounds unless directed by a clinician.
• Allergy: discontinue immediately if signs of hypersensitivity appear.
• Concurrent topical agents: do not layer with other irritant or occlusive preparations without professional advice.
• Store at ambient temperature: keep in the original container, protect from moisture and direct sunlight.

Ichthammol may interact with other topical products or dressings.

Major Interactions (Avoid)

• Use with potent topical corticosteroids on the same area: increased risk of skin atrophy.
• Application under occlusive dressings: may enhance systemic absorption and toxicity.

Moderate Interactions (Monitor Closely)

• Combination with other antiseptic creams: potential for increased local irritation.
• Concurrent use of photosensitising agents: heightened sun sensitivity.
• Use alongside systemic antibiotics: monitor infection response, though no direct pharmacokinetic interaction is known.
