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 prevent 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. The adverse reactions occur because the skin comes in contact with an irritating substance or chemical. Dyes and fragrances are typically the most common causes of detergent allergies. Recognizing an allergic reaction may be difficult, since the symptoms may 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 sensitive. Irritating laundry detergent, for instance, can cause a rash that may cover almost the entire body. An irritating dish detergent, on the other hand, may only affect the allergy sufferer's hands.
The rash associated with this type of allergic reaction will also usually be very itchy. Skin may also feel tight, dry, and cracked. Constant itching and cracked skin can allow bacteria to enter the body, resulting in an infection. Sneezing and itchy, watery eyes may also occur, and these symptoms are typically 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. This is typically more common in severe allergic reactions, though. The affected area may also be slightly swollen.
While it is very rare, anaphylactic shock is also possible during a severe allergic reaction to detergent. This is usually very serious, and it can result in the 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, in order to confirm his diagnosis. Treating an allergic reaction of this type is usually very simple, and it 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 typically involves removing the offending irritant. This usually means that a person who has an adverse reaction to detergent must change to a different brand or type. Hypoallergenic detergents are usually recommended.
