Armpit allergy: what it can be, symptoms and treatment

Armpit allergy can be noticed through the appearance of some symptoms such as intense itching, blisters, red spots, redness or a burning sensation, for example. This inflammatory reaction can happen due to the use of deodorants with irritating substances, such as fragrances and alcohol, for example, or due to skin friction with synthetic fabrics or shaving with a razor or depilatory creams, for example.

So, when the first symptoms of allergy appear, the most recommended thing is to wash the armpits with plenty of water and neutral pH soap, to avoid aggravation of the reaction, then apply a little soothing cream, with aloe, for example, to moisturize and soothe the skin. If symptoms do not improve or worsening is noted, it is recommended to consult a dermatologist so that the most appropriate treatment is indicated.

Causes of armpit allergy

Axilla allergy can be triggered by several factors, the main ones being:

  • Use of deodorants with irritating substances such as parabens, alcohol and fragrances, for example;
  • Axilla friction with own skin;
  • Axilla friction with synthetic fabrics such as lycra, polyester or nylon;
  • Excessive heat, being more common in summer;
  • Excessive sweating, which may be related to heat or physical activity;
  • Dryness of the region, which makes the skin rougher and favors friction;
  • Shaving with a razor or depilatory creams;

Thus, it is important to identify the factor responsible for the allergy so that it is possible to avoid or adopt strategies that help alleviate and prevent the onset of symptoms.

Main symptoms

Symptoms of armpit allergy can be noticed as soon as an irritating product is used on the site, after shaving or over time, the main ones being:

  • Burning sensation and irritated skin;
  • Blisters or red spots on the skin;
  • Axilla lump;
  • Very intense itching;
  • Redness;
  • Local peeling in some cases.

For people with greater sensitivity, it is possible to notice more serious allergy symptoms, such as swelling of the face, eyes or tongue, feeling of something stuck in the throat or difficulty breathing. In these cases, it is advisable to go immediately to the hospital to take an antihistamine and a corticosteroid directly into the vein, avoiding serious complications, such as respiratory arrest.

Also check that other problems can cause red spots on the skin.

How to confirm armpit allergy

To confirm an allergy in the armpit, it is recommended that a dermatologist be consulted so that the signs and symptoms presented are observed and it is possible to indicate the possible cause of the symptoms. An allergy test can also be performed to confirm the diagnosis and more accurately identify the component that could be causing the allergy. Learn how the allergy test is done.

What to do

When allergy symptoms appear in the allergy, it is important to take action quickly, if necessary:

  1. Wash the armpit area with plenty of water and soap of neutral pH;
  2. Applying hypoallergenic or soothing products on the skin, such as creams or lotions with aloe, chamomile or lavender for example, which soothe and moisturize the skin;
  3. Applying cold water compresses to the armpits to reduce symptoms of irritation and burning sensation.

After washing and moisturizing the skin, it is expected that after 2 hours the symptoms will disappear completely, but if this does not happen or if the symptoms worsen, it is recommended that you consult a dermatologist as soon as possible. Also, if the symptoms progress to difficulty breathing or a feeling of something stuck in the throat, it is recommended to go quickly to the hospital or emergency room, as these are signs of an anaphylactic reaction, which is a medical emergency.

After evaluating the symptoms, the dermatologist may recommend the use of antihistamine drugs, such as loratadine or fexofenadine hydrochloride (Allegra), or corticosteroids to promote symptom relief. In cases where there is a lot of redness or itching in the armpits, ointments with antihistamine properties may also be recommended, which help to relieve these symptoms.
