Treatment of Intertriginous Rash (Intertrigo) Under the Breasts

Managing Pruritus

The American Academy of Dermatology recommends applying topical low-potency corticosteroids, such as hydrocortisone 2.5% or alclometasone 0.05%, to reduce inflammation and itching, applied 3-4 times daily for up to 2 weeks, with a strength of evidence based on expert opinion 1
Oral antihistamines, such as cetirizine or loratadine 10 mg daily, or hydroxyzine 10-25 mg four times daily, can provide additional relief from itching in patients with intertrigo, according to the Journal for ImmunoTherapy of Cancer 1

The European Academy of Dermatology and Venereology suggests using absorbent materials, such as clean cotton cloth or gauze, between skin folds to reduce moisture accumulation, and applying alcohol-free moisturizers with urea (5-10%) to surrounding non-inflamed skin to maintain barrier function, with a moderate strength of evidence 2, 3
Avoiding frequent washing with hot water and harsh soaps, which disrupt the skin barrier, is recommended by the Annals of Oncology, with a high strength of evidence 3, 4

The Infectious Diseases Society of America recommends watching for warning signs that indicate bacterial involvement, such as yellow crusting or discharge from the rash, painful skin lesions that worsen despite antifungal treatment, and failure to respond to oral antibiotics covering gram-positive organisms after 48-72 hours, with a high strength of evidence 3
Administering antibiotics for at least 14 days based on culture sensitivities is recommended by the Annals of Oncology, with a moderate strength of evidence 3

The American Academy of Dermatology advises against using high-potency topical steroids in intertriginous areas, as they can cause skin atrophy and worsen fungal infections, with a high strength of evidence 1
The European Academy of Dermatology and Venereology recommends avoiding combining topical steroids with antifungals for more than 2 weeks without reassessment, as prolonged steroid use can mask infection, with a moderate strength of evidence 2

For uncomplicated candidal intertrigo, apply topical azoles to the affected skin folds and keep the area dry; if bacterial superinfection is present, add topical mupirocin for streptococcal infections or oral erythromycin for Corynebacterium, as recommended by the Infectious Diseases Society of America 5, 6

Topical azoles, such as clotrimazole, miconazole, ketoconazole, oxiconazole, or econazole, are effective for candidal intertrigo and should be applied to affected areas, according to the Clinical Infectious Diseases guidelines 5, 6
Topical nystatin is equally effective as an alternative for candidal intertrigo, as stated by the Clinical Infectious Diseases guidelines 5, 6
For resistant candidal cases, oral fluconazole 100 mg daily for 7-14 days can be used if topical therapy fails, as recommended by the Clinical Infectious Diseases guidelines 5

For suspected infection with unclear pathogen, obtain bacterial culture before initiating therapy, as recommended by the Clinical Infectious Diseases guidelines 5
Do not use alcohol-containing preparations in skin folds, as they can worsen dryness and irritation, according to the Annals of Oncology guidelines 7

Obese and diabetic patients are particularly susceptible to intertrigo in skin folds and require more aggressive moisture control measures and regular monitoring for secondary infections, as stated by the Clinical Infectious Diseases guidelines 5, 6
Drainage is the most important intervention for paronychia or abscess formation to prevent progression to sepsis, according to the Clinical Infectious Diseases guidelines 5, 6
