Our underarm is one of the most sensitive skins in our body. This area is prone to rubbing, and on top of it, it doesn’t get much light and air. These factors, on top of it being thin, can be a huge dilemma for some. By just using inappropriate products, shaving, or waxing, and not paying TLC on your underarm, you can irritate or dry out the area.  

Having rashes on your armpit is uncomfortable and embarrassing for some. Read on to see how to treat and prevent underarm rash.

Treatment for Underarm Rash 

Many things can cause an underarm rash. It would be best to determine the cause and proceed with the most suitable course of treatment. A medical provider or a doctor may advise you one of the following options:

  • Over-the-counter medicine and anesthetic medicine to numb the area or soothing medicine and antihistamine to lessen discomfort and itchiness
  • Ointments, cream, topic steroids like hydrocortisone to relieve inflammation
  • Calamine lotions or creams to provide relief
  • Antifungal medications, creams, gels, or sprays if it’s candida rash or yeast infection. 

Home Remedies

  • A warm bath with skin-calming products such as oatmeal, apple cider vinegar, salt, and baking soda
  • Cold compress for relief.
  • Applying oils like coconut and sunflower oil.

You can try OTC medicine and home remedies. If the symptoms persist, you might need prescription medicines and treatment.

If you already see or feel any symptoms avoid scratching on using something to prevent further irritation and infection.

You can see changes in your overall health if you follow all of these. If your underarm rash is still there after these suggested treatments and preventative measures, you should seek help from your doctor.
