From the Research
For treating axillary heat rash, I recommend using over-the-counter topical corticosteroid creams like 1% hydrocortisone or calamine lotion, as they are effective in reducing inflammation and itching associated with heat rash, as supported by the most recent evidence from 2. When choosing a topical corticosteroid, it's essential to consider the potency and potential adverse effects, as discussed in 2. Some key points to consider when using topical corticosteroids for axillary heat rash include:
- Apply a thin layer to clean, dry underarm skin 1-2 times daily for up to 7 days
- Antifungal creams containing clotrimazole or miconazole may also help if the rash has a fungal component
- For immediate relief, try cooling the area with a cold compress before applying medication
- Keep the underarm area clean and dry, wear loose-fitting clothing made of breathable fabrics, and avoid harsh soaps or deodorants until the rash resolves It's also important to note that if the rash doesn't improve within a week, shows signs of infection (increased redness, warmth, pus), or if you develop fever, seek medical attention as prescription-strength treatments may be necessary, as suggested by the general principles of treating skin infections discussed in 3, 4, 5, and 6.
