From the Guidelines
Antibiotics are not typically recommended for minor paronychia, and treatment should focus on gentle skin care and prevention of further irritation. According to the ESMO clinical practice guidelines 1, the management of paronychia depends on the severity of the condition, and for Grade 1 treatment, topical antibiotics/corticosteroids may be used, but only if there are signs of infection. The guidelines recommend gentle skin care instructions, including wearing comfortable shoes, wearing gloves while cleaning, and avoiding biting nails or cutting nails too short, as well as the use of antimicrobial soaks and washing with cleansers and water 1.
Key Considerations
- The pathogenesis of paronychia is thought to result from inhibition of the EGFR and downstream EGFR-dependent pathways in basal and suprabasal keratinocytes, leading to altered differentiation and migration of epidermal cells 1.
- Secondary bacterial or mycological superinfections are present in up to 25% of cases, and both gram-positive and gram-negative organisms have been implicated 1.
- Prevention strategies include avoiding nail biting, finger sucking, and excessive moisture exposure, as well as proper hand hygiene and nail care.
Treatment Approach
- For mild cases, topical antibiotics like povidone iodine 2% may be used if there are signs of bacterial infection 1.
- Oral antibiotics are only indicated for severe or worsening infections, and the choice of antibiotic should cover Staphylococcus aureus and Streptococcus species, the most common causative organisms.
- The use of oral antibiotics should be guided by the severity of the infection and the presence of signs of bacterial infection, such as discharge or nail plate separation 1.

From the Research
Treatment of Minor Paronychia
- The treatment of minor paronychia typically involves warm soaks with or without Burow solution or 1% acetic acid, as well as topical antibiotics and steroids 2.
- In some cases, oral antibiotics may be necessary, especially if the patient is immunocompromised or has a severe infection 2, 3.
- The choice of antibiotic should be based on the most likely pathogens and local resistance patterns 2, 3.
Use of Topical Antibiotics
- Topical antibiotics can be effective in treating minor paronychia, especially when combined with other treatments such as warm soaks and topical steroids 2, 4.
- A study found that a combination of topical antifungals and a molecule with anti-inflammatory activity was effective in treating moderate and chronic paronychia 4.
Role of Oral Antibiotics
- Oral antibiotics are usually not needed for minor paronychia, unless the patient is immunocompromised or has a severe infection 2.
- In cases where oral antibiotics are necessary, options such as beta-lactamase-stable penicillins, macrolides, and cephalosporins may be considered 3.
- The choice of oral antibiotic should take into account the resistance profile of the target pathogen, as well as the agent's antibacterial profile and pharmacokinetic properties 3.
