What is Ciclopirox?
Ciclopirox, the active ingredient in Mycoster, is an antifungal presented as a topical formulation for cutaneous use. Available over‑the‑counter in the EU, it treats superficial fungal infections of the skin and nails in both adults and children, addressing conditions such as athlete’s foot, ringworm, and seborrheic dermatitis.
GNH USA supplies Mycoster as a licensed, GDP‑compliant international pharmaceutical supplier, delivering the product to hospitals, pharmacies and clinics worldwide under stringent quality and regulatory standards.
What is Ciclopirox used for?
Mycoster (ciclopirox) is used to treat fungal skin conditions by targeting dermatophytes, yeasts and moulds. - Superficial dermatophyte infections (e.g., tinea pedis, tinea corporis): reduces fungal growth and relieves itching and scaling. - Cutaneous candidiasis: controls yeast proliferation and improves lesion appearance. - Seborrheic dermatitis: diminishes Malassezia‑related inflammation and flaking. - Onychomycosis (when formulated for nail use): penetrates the nail plate to inhibit fungal metabolism and promote clearer nail growth.
What are the side effects of Ciclopirox?
Topical ciclopirox may cause local skin reactions, most of which are mild and reversible.
Common Side Effects: - Burning sensation - Itching - Stinging - Redness or mild irritation
Serious or Rare Side Effects: - Severe allergic reaction (e.g., angioedema, anaphylaxis) - Stevens‑Johnson syndrome or toxic epidermal necrolysis - Extensive skin blistering or ulceration
What precautions apply to Ciclopirox?
When using Mycoster, observe the following precautions to ensure safe and effective treatment. - Avoid application on broken or inflamed skin: limit use to intact areas. - Do not apply near eyes, mouth or mucous membranes: prevent accidental irritation. - Keep out of reach of children: store securely to avoid misuse. - Discontinue if severe irritation or allergic reaction occurs: seek medical advice. - Store at room temperature: keep in original packaging, protect from moisture and direct sunlight.
What does Ciclopirox interact with?
Ciclopirox has a low potential for systemic drug interactions, but certain topical combinations may affect safety or efficacy.
Major Interactions (Avoid): - Concurrent use with other topical irritants (e.g., chemical peels): may increase skin irritation. - Simultaneous application with systemic antifungal therapy: may raise risk of systemic absorption, though rare.
Moderate Interactions (Monitor Closely): - Use with topical corticosteroids: may reduce antifungal effectiveness. - Combination with alcohol‑based hand sanitizers: can compromise skin barrier and increase irritation. - Phototherapy or UV exposure: may heighten photosensitivity of treated skin.
