Treatment of Axillary Rash

Initial Assessment and General Approach

The American College of Physicians recommends that the treatment of axillary rash should include topical corticosteroids, appropriate antibiotics if infection is suspected, and addressing underlying causes while maintaining good skin care practices, with a strength of evidence based on clinical guidelines 1, 2
Identify and treat predisposing conditions such as excessive moisture, friction, and skin irritants, as recommended by the Infectious Diseases Society of America 2

Apply topical low to moderate potency corticosteroids such as hydrocortisone 2.5% to reduce inflammation, as suggested by the European Society of Medical Oncology 3
Use alcohol-free moisturizers, preferably containing 5-10% urea, at least twice daily to maintain skin barrier function, with a recommendation from the American Academy of Dermatology 3, 4
If infection is suspected, obtain bacterial cultures before starting antimicrobial therapy, as advised by the European Society of Clinical Microbiology and Infectious Diseases 3, 5

For suspected bacterial infection in the axilla, topical antibiotics such as clindamycin 2% or erythromycin 1% cream may be used, with a recommendation from the Infectious Diseases Society of America 6
For more extensive infection, oral antibiotics such as metronidazole, ciprofloxacin, levofloxacin, or ceftriaxone may be necessary, as suggested by the Clinical Infectious Diseases society 1, 2, 7

Apply topical corticosteroids such as prednicarbate cream 0.02%, with a recommendation from the European Society of Medical Oncology 6
For severe cases with significant inflammation, consider short-term oral systemic corticosteroids, as advised by the Infectious Diseases Society of America 2
Avoid skin irritants such as harsh soaps, solvents, or disinfectants, with a recommendation from the European Society of Medical Oncology 3, 4

For mild to moderate acneiform rashes, use topical antibiotics such as clindamycin 2% or erythromycin 1%, with a recommendation from the European Society of Medical Oncology 6
For moderate to severe cases, add oral antibiotics such as doxycycline or minocycline for at least 2 weeks, as suggested by the European Society of Medical Oncology 4, 6

Avoid frequent washing with hot water as this can irritate and worsen axillary rashes, with a recommendation from the European Society of Medical Oncology 3, 4
Use mild, non-soap cleansers to clean the affected area, as advised by the European Society of Medical Oncology 3
Apply sunscreen (SPF 15 or higher) to exposed areas if applicable, with a recommendation from the European Society of Medical Oncology 3

If the rash does not improve after 2 weeks of appropriate treatment, consider referral to a dermatologist, as suggested by the European Society of Medical Oncology 6
For severe cases with extensive involvement or signs of systemic infection, consider referral to an infectious disease specialist, as advised by the Clinical Infectious Diseases society 1
