An allergic reaction to soap will often result in a red itchy rash, or hives. The affected skin will also usually be dry, and the area may swell. When the fumes of a particular soap are inhaled, they can possibly cause mild respiratory and eye problems. To pinpoint the cause of a soap allergy, a person should take note of where the symptoms have occurred. If the symptoms of a soap allergy are present on areas of the body that come in contact with clothing, for example, the most likely cause would be laundry soap.
Skin irritation is typically the most common sign of an allergic reaction to soap. This irritation will typically be present on areas of the skin that came in contact with the soap. In some cases, however, a person may break out in hives all over his body.
A red, itchy rash is typically the most common sign of an allergy to soap. This rash will also usually be dry and flaky. In more serious cases, small blisters may also appear on the rash. Swelling can also occur, and this can cause the skin to feel tight. Rashes associated with soap allergies may also feel very warm to the touch.
Sometimes, an allergic reaction to soap may be so severe that it can cause symptoms when the fumes are inhaled. These symptoms may include a runny nose and sneezing. Headaches, dizziness, and watery eyes may also be symptoms of a soap allergy.
Laundry soap is one of the most common causes of an allergic reaction. Symptoms of this type of allergic reaction will usually occur on areas of the body covered by clothing. A red, itchy rash will often appear on or near the torso, groin, and legs, for example. Unless it is a severe allergy, symptoms will not usually occur on unclothed areas of the body, such as the face or hands.
Other types of soaps can also cause allergic reactions. Hand soap and dish soap, for instance, will often cause skin irritation just on the hands. If a person believes he is allergic to a particular type of soap, he should immediately stop using the soap.
An allergic reaction to soap can usually be treated with over-the-counter medications. Topical antihistamines or corticosteroids can be applied to the affected area to relieve the external symptoms. Oral antihistamines may also help relieve these symptoms. Any soap that causes an allergic reaction should also be avoided.
