Paronychia Treatment Guidelines

Initial Assessment and Treatment

The American College of Physicians recommends evaluating the severity of paronychia based on redness, edema, discharge, and presence of granulation tissue, and checking for presence of pus or abscess formation, which mandates drainage rather than conservative management alone 1, 2
Predisposing factors, including ingrown toenail, occupational exposures, or medication-induced causes, should be identified 1, 2
For acute paronychia, treatment with warm water or white vinegar soaks, topical 2% povidone-iodine, and mid-to-high potency topical steroid ointment to the nail folds is recommended 1, 2, 3

For Grade 1 (Mild) Paronychia, antiseptic soaks, topical 2% povidone-iodine, and mid-to-high potency topical steroid ointment are recommended 1, 2, 3
For Grade 2 (Moderate) Paronychia, oral antibiotics, such as cephalexin or amoxicillin-clavulanate, and topical very potent steroids, antifungals, antibiotics, and/or antiseptics are recommended 1, 2, 3, 4
For Grade 3 (Severe) Paronychia, swabbing for culture, prescribing appropriate antibiotics, and performing surgical drainage are recommended 1, 3

High-potency topical corticosteroids are more effective than antifungals for chronic paronychia and should be first-line treatment 1, 2
Regular application of emollients to cuticles and periungual tissues, and identification and elimination of irritants are also recommended 1, 2

Keeping hands and feet dry, avoiding nail trauma, moisturizing hands and feet regularly, wearing protective gloves, and wearing comfortable well-fitting shoes are recommended to prevent recurrence 1, 2, 4

Reassessing after 2 weeks of treatment and referring to dermatology or podiatry if no improvement is seen are recommended 1, 2, 3
