Many types of detergents, including laundry detergent and dish detergent, can cause an allergic reaction. An itchy rash is a common sign of an allergic reaction to detergent. Other allergy symptoms, such as sneezing, may also occur. In more severe cases, the affected area may also be hot to the touch and blisters may form. To avoid an allergic reaction, the person will usually need to switch to a different detergent.
An allergic reaction to detergent is often classified as contact dermatitis. Adverse reactions occur because the skin comes into contact with an irritating substance or chemical. Dyes and fragrances are usually the most common causes of allergies to detergents. Recognizing an allergic reaction can be difficult, as the symptoms can be similar to other skin disorders.
A rash is one of the most common signs of an allergic reaction to detergent. The skin, usually where it was exposed to the detergent, will usually be red and tender. Irritating laundry detergent, for example, can cause a rash that can cover almost the entire body. An irritating dish detergent, on the other hand, can only affect the allergic person's hands.
The rash associated with this type of allergic reaction is also often very itchy. The skin may also feel tight, dry, and cracked. Constant itching and cracked skin can allow bacteria to enter the body, resulting in infection. Sneezing and itchy, watery eyes may also occur, and these symptoms are usually caused by an allergy to a particular fragrance.
Some people who have an allergic reaction to detergent may also notice that their skin feels warm or even hot. Small blisters may also form. However, this is usually more common in severe allergic reactions. The affected area may also be slightly swollen.
Although very rare, anaphylactic shock is also possible during a severe allergic reaction to detergent. This is usually very serious and can lead to swelling of the face, including the eyes and mouth. Throat swelling during an allergic reaction can lead to breathing difficulties and possibly death.
A medical professional will usually want to do a skin patch test before treatment, to confirm their diagnosis. Treating such an allergic reaction is usually very simple and can be done at home. A topical antihistamine can be applied to an itchy rash, and oral antihistamines can be taken to help relieve severe symptoms.
Preventing an allergic reaction to detergent usually involves removing the offending irritant. This usually means that a person who has an adverse reaction to detergent should switch to a different brand or type. Hypoallergenic detergents are generally recommended.
