I have comprehensive information now. Here is the full treatment guide for paronychia:
Paronychia - Treatment Guide
Note: "chilo8ce" in your query appears to be a typo - likely "choice" (treatment of choice). The full treatment framework is covered below.
What Is Paronychia?
Paronychia is inflammation/infection of the nail folds (periungual tissue). It is classified as acute or chronic, and each has a different treatment approach.
ACUTE PARONYCHIA
Cause: Usually Staphylococcus aureus; also Streptococcus pyogenes, anaerobes (nail biters/finger suckers), or Pseudomonas.
Step-by-step Treatment:
| Stage | Treatment |
|---|---|
| Early / no abscess | Warm soaks 10-15 min, 3-4x daily ± topical antibiotic |
| Mild infection | Topical antibiotic (mupirocin 2-4x/day, or gentamicin ointment) ± topical corticosteroid (betamethasone) |
| Moderate / cellulitis | Oral antibiotics (see below) |
| Abscess formed | Incision and drainage (I&D) - mandatory |
| Fulminant infection | Surgical debridement |
Oral Antibiotic Choices:
-
First-line (MSSA coverage):
- Dicloxacillin/cloxacillin 250 mg QID, OR
- Cephalexin 250-500 mg TID-QID, OR
- Amoxicillin-clavulanate (also covers anaerobes - preferred for nail biters)
-
MRSA coverage (or penicillin allergy):
- Trimethoprim-sulfamethoxazole (TMP-SMX), OR
- Clindamycin 300 mg QID (also covers anaerobes), OR
- Doxycycline
-
Anaerobic coverage (finger sucking/nail biting):
- Amoxicillin-clavulanate (Augmentin), OR
- Clindamycin
From Merck Manual: Early treatment is warm compresses + oral antibiotic effective against staphylococci (dicloxacillin or cephalexin 250 mg QID). In MRSA-prevalent areas, use TMP-SMX.
CHRONIC PARONYCHIA
Cause: Primarily Candida albicans (>95% of fungal cases); may involve Gram-negative organisms or atypical mycobacteria if bacterial.
Treatment:
- Avoid the cause - keep hands dry, use rubber gloves over cotton gloves for wet work
- Topical antifungal - miconazole (first-line)
- Topical corticosteroid - betamethasone 0.1% or methylprednisolone (reduces inflammation, improves cure rate when combined with antifungal)
- Tacrolimus 0.1% ointment - may be more effective than betamethasone in some studies
- Oral antifungal (if topical fails):
- Fluconazole, OR
- Terbinafine or itraconazole (Campbell's Operative Orthopaedics 15th Ed, p. 3377)
- Surgical (if all else fails): Eponychial marsupialization (Keyser-Eaton technique) - removes a crescent of proximal nail fold
Andrews' Diseases of the Skin: Antifungal + topical corticosteroid combination in candidal chronic paronychia gives a higher cure rate than antifungals alone (cure rate ~50% with antifungals only).
SPECIAL SITUATIONS
| Situation | Treatment |
|---|---|
| Diabetic patients | Control diabetes; more aggressive antibiotic therapy; monitor for cellulitis |
| Immunocompromised | Antivirals (acyclovir, valacyclovir) if herpetic; broader antibiotic coverage |
| Herpetic whitlow (mimics paronychia) | Do NOT incise - resolves in 3-4 weeks; acyclovir for immunocompromised |
| EGFR inhibitor-related | Common side effect; treat as acute paronychia |
| Toe paronychia with diabetes/PVD | Monitor closely for cellulitis, lymphadenopathy, fever |
SURGICAL TECHNIQUE (I&D)
For abscesses, the nail fold is gently elevated away from the nail plate - pus often drains without a blade. If needed, a needle or #11 blade is used after alcohol cleansing. For recurrent or subungual extension, partial nail avulsion may be required.
Summary - Treatment of Choice:
- Acute (no abscess): Warm soaks + topical mupirocin ± betamethasone
- Acute (with abscess): I&D + oral antistaphylococcal antibiotic (cephalexin/dicloxacillin)
- Chronic: Topical miconazole + topical corticosteroid; oral fluconazole/itraconazole if refractory
- MRSA suspected: TMP-SMX or clindamycin

Is mupirocin applied on open wound or closed?

Here is a clear answer:
Mupirocin: Open Wound or Closed Skin?
Mupirocin can be applied to BOTH - but with important distinctions:
Applied to Open/Broken Skin (Primary Use)
Mupirocin is specifically indicated for superficial open or broken skin infections, including:
- Impetigo (crusted, open lesions) - its main FDA indication
- Small open wounds with secondary bacterial infection
- Burn wound surfaces (partial thickness burns, donor sites, graft sites)
- Paronychia - the inflamed, often macerated/broken nail fold skin
- Secondarily infected traumatic skin lesions
Applied to Intact Closed Skin
- Nasal decolonization of S. aureus/MRSA carriers (intranasal mupirocin) - intact mucosa
- Post-procedure/surgical wounds - applied over closed surgical incisions to reduce infection risk
- Central line exit sites - to prevent catheter-related bloodstream infections
How to Apply for Paronychia Specifically
- Clean the area first - wash hands, gently clean the nail fold
- Apply a small amount (thin layer) directly onto the inflamed nail fold skin
- Cover with a light dressing/bandage if desired
- Repeat 2-4 times daily for 5-10 days
- Do NOT apply inside deep wounds, eyes, or mucous membranes
Key Points
| Feature | Detail |
|---|---|
| Formulation | Petroleum-based ointment (polyethylene glycol base) |
| Spectrum | Gram-positive cocci - excellent S. aureus (including MRSA) and Streptococcus coverage |
| Penetration | Works on the skin surface and superficial dermis - not for deep tissue infections |
| Duration | Max 10 days - avoid prolonged use to prevent resistance |
| Avoid | Do NOT use on deep puncture wounds or mucous membranes (ointment base); use cream formulation for mucosal surfaces |
Important caveat from Drugs.com: It should only be applied to an open wound when a clinician has diagnosed a superficial bacterial skin infection. For deep or large open wounds, it is NOT appropriate - systemic antibiotics are needed instead.
In paronychia, since the infection is superficial (nail fold skin), mupirocin fits perfectly - whether the skin surface is intact but inflamed, or has small breaks/cracks from maceration.
