Underarm rash Treatment
The treatment used for underarm rash depends on what the cause of the rash is. Some treatments that may be used include:
- If the underarm rash is caused by an allergic reaction to soaps, shaving cream, detergents, deodorant, perfume, etc, change what you are using until you find one that does not cause underarm rash.
- If it is due to folliculitis you will need to see your physician for a prescription of a topical cream to help reduce your discomfort and help calm down the inflamed follicle.
- If it is due to a fungal infection you will need to apply antifungal creams to the area and also decrease the amount of milk-products and milk you are consuming. If over-the-counter fungal creams do not take care of the problem you will need to talk to your physician about a prescription for a stronger antifungal medication.
- If you develop a heat rash you need to try and keep the area aired out, dry, and cool. You can also apply cool compresses to the area to help with the itching. Try not to scratch the area as this can only aggravate the situation and make it worse. You can also apply ice cubes to help cool down the heat rash.
- If the cause is shaving, make sure that you are using a new blade or razor and try a shaving cream or gel for sensitive skin.
- Do not wear tight clothing, especially in the heat, as this can cause friction under your arms. Try to wear light, loose fitting clothes.
- Make sure that you are keeping your underarms dry and clean by washing under the area at least two times a day. You can also apply aloe Vera gel on the rash.
- Before going to bed apply a light moisturizer under your arms.
If your underarm rash is caused by a medical condition talk to your physician to see which treatment would work best for your condition.
