# Amorolfine 5% Nail Lacquer
*The supplied name appears to be repeatedly URL-encoded and likely refers to **amorolfine 5% nail lacquer**. Verify the actual product and concentration locally.*
## Overview
Topical antifungal lacquer containing amorolfine, used for selected fungal nail infections. It has prolonged activity in the nail plate and is minimally absorbed systemically.
## Primary Indications
- Mild-to-moderate **onychomycosis** caused by dermatophytes, yeasts, or molds.
- Generally suitable when infection involves:
- A limited number of nails, and
- The distal/lateral nail rather than the nail matrix.
- Confirm diagnosis, preferably by microscopy and/or culture, because dystrophic nails are not always fungal.
## Adult Dosing
- **Apply amorolfine 5% lacquer once or twice weekly** to each affected nail.
- Before each application:
1. File down affected nail areas.
2. Clean and degrease the nail.
3. Apply lacquer over the entire nail surface and under the free nail edge when possible.
4. Allow to dry according to product instructions.
- Remove residual lacquer and file the nail approximately **weekly**, according to the product instructions.
- Continue until clinical and mycological cure:
- **Fingernails:** usually about **6 months**
- **Toenails:** usually **9–12 months**
- There is no established universal maximum duration; treatment should be reassessed if there is no meaningful improvement after approximately **3–6 months**.
## Pediatric Dosing
- **Children and adolescents:** Safety and efficacy are not well established; routine use is generally **not recommended in patients younger than 18 years** unless directed by a specialist.
- No established pediatric dose or maximum dose.
## Dose Adjustments
- **Renal impairment:** No adjustment expected because systemic absorption is minimal.
- **Hepatic impairment:** No adjustment expected; clinical experience is limited.
- **Older adults:** No routine adjustment.
- Extensive disease, matrix involvement, or failure of topical therapy may require specialist evaluation and consideration of systemic antifungal treatment.
## Contraindications
- Known hypersensitivity to amorolfine or any excipient.
- Do not apply to skin, eyes, or mucous membranes.
- Avoid use during **pregnancy or breastfeeding** unless the expected benefit clearly outweighs potential risk; human data are limited.
- Avoid self-treatment without medical assessment when there is:
- Diabetes, significant peripheral vascular disease, neuropathy, or immunosuppression
- Pain, cellulitis, marked inflammation, or extensive nail involvement
## Adverse Effects
Usually localized and mild:
- Nail discoloration or brittleness
- Burning, stinging, irritation, redness, itching, or contact dermatitis around the nail
- Rare: blistering, severe hypersensitivity, or allergic reaction
Stop treatment and seek medical attention for facial swelling, breathing difficulty, widespread rash, or severe blistering.
## Key Drug Interactions
- Clinically important systemic drug interactions are unlikely because absorption is minimal.
- Avoid or minimize:
- Cosmetic nail polish
- Artificial nails
- Other medicated nail products unless specifically advised
- Some formulations permit cosmetic nail polish after application; follow the specific product labeling.
- Do not share files, applicators, or nail-care equipment.
## Monitoring
- Confirm fungal infection when feasible before treatment.
- Inspect affected nails periodically for:
- Proximal clear nail growth
- Reduced discoloration, thickening, and subungual debris
- Irritation or allergic reactions
- Assess adherence and technique.
- Consider repeat mycological testing if treatment fails or the diagnosis is uncertain.
- Refer for evaluation if there is no improvement after **3–6 months**, infection involves the nail matrix, or multiple nails are affected.
## Clinical Pearls
- Treatment must continue until the infected nail has grown out; improvement may take several months.
- Regular filing and cleaning are important for penetration and effectiveness.
- Topical therapy is less effective for extensive disease, matrix involvement, or markedly thickened nails.
- Keep feet dry, change socks regularly, use breathable footwear, and treat coexisting athlete’s foot to reduce recurrence.
- Do not use the same nail file on unaffected nails.
- Amorolfine 5% lacquer products and labeling vary by country; application frequency, removal instructions, and age restrictions may differ.
