Linola Sept (Clioquinol)

Clioquinol is used topically to manage fungal and protozoal skin conditions.

• Tinea (ringworm) infections: reduces fungal growth and promotes resolution of skin lesions.
• Cutaneous fungal infections: treats dermatophyte‑induced dermatitis and improves skin appearance.
• Skin infections caused by susceptible organisms: eliminates susceptible yeasts and protozoa from affected areas.

• Clioquinol exerts its antifungal and antiprotozoal activity by chelating essential metal ions such as iron and zinc. This chelation disrupts metal‑dependent enzymes and compromises microbial cell membrane integrity, leading to inhibition of growth and cell death of susceptible fungi and protozoa. The resulting impairment of metabolic pathways prevents replication and facilitates clearance by the host immune system. Topical application concentrates the effect at the site of infection while minimizing systemic exposure.

Clioquinol may cause local skin reactions and, rarely, systemic adverse events.

Common Side Effects

• Skin irritation: mild redness or discomfort at the application site.
• Itching: transient pruritus following use.
• Burning sensation: brief warmth or stinging.
• Erythema: localized redness.
• Contact dermatitis: allergic skin response.
• Dryness: flaking or scaling of treated skin.

Serious or Rare Side Effects

• Allergic reaction: angioedema or severe swelling.
• Severe dermatitis: extensive skin inflammation.
• Systemic neurotoxicity: rare neurologic symptoms.
• Agranulocytosis: profound reduction in white blood cells.
• Photosensitivity: heightened skin reaction to sunlight.

When using Linola Sept, observe the following precautions to ensure safe and effective treatment.

• Avoid application on broken or inflamed skin: may increase irritation.
• Do not use on mucous membranes or ocular surfaces: product not intended for these areas.
• Discontinue use if severe irritation or allergic reaction occurs: seek medical advice.
• Use with caution in children under 2 years: limited safety data.
• Limit continuous use to recommended duration: prolonged exposure may cause sensitisation.
• Store at room temperature: keep in original container, protect from moisture and light.

Clioquinol can interact with other agents applied to the skin or affecting metal ion balance.

Major Interactions (Avoid)

• Concurrent use with other topical metal‑chelating agents may reduce efficacy.
• Use with systemic metal chelators (e.g., deferoxamine) may diminish activity.
• Co‑application with strong irritants may increase skin damage.

Moderate Interactions (Monitor Closely)

• Combined use with topical corticosteroids may mask irritation signs.
• Use with other antifungal creams may alter absorption.
• Concurrent use with phototoxic agents may increase risk of photosensitivity.
