Skin hives in infants lead to some nasty rashes all over the body. The baby feels itchy while parents feel helpless, worrying as to what caused the condition. There are several reasons behind skin hives in infants. Read this post by MomJunction to learn all about the cause, symptoms, and ways to treat skin hives in babies.
What Are Hives?
Hives are a skin reaction characterized by tiny, red bumps localized to a body part or spread across the body. It is also called urticaria or skin hives. Hives can appear and then completely disappear in a few hours. They could also switch places by randomly disappearing on one part of the body and appearing on another (1).
Several conditions and situations can trigger hives in infants.
What Causes Hives In Babies?
Hives form when blood plasma leaks out of the blood vessels and flows into the skin. The leakage is caused by the chemical histamine, which is secreted by the immune system cells called mast cells that are present in the bloodstream. Mast cells release histamine to cause hives in the following conditions:
- Sweat-induced hives come due to playing, heat, or even thick clothing. This condition is called cholinergic urticaria. The reasons for this skin hives, too, is unknown, but it is believed that it happens due to skin’s hypersensitivity towards its own sweat (11).
- Friction-induced hives are a result of the skin brushing against clothes. Due to this, some babies may develop raised bump-like hives at the spots where the skin is scratched, rubbed, or comes under frequent friction. This type of condition is called dermatographism or dermatographism urticaria. It is not known why this friction causes skin hives (9).
- Viral and bacterial infections are another leading cause of hives and are quite likely to be seen all over the body. As the immune system fights a virus, the body may display hives. This type of condition is called viral urticaria. Viral respiratory illness also commonly causes viral skin hives in babies since body produces immunoglobulins that fight the pathogen, but also induce hives (7). Among bacterial hives, Streptococcus bacteria-induced hives are most notable. Some parasites may also result in the formation of skin hives.
- Food allergies are the leading cause of hives in babies (2). Experts state that foods such as nuts (including peanuts), fish, shellfish, and eggs are most likely to cause hives induced by an allergic reaction (3). Infants, who are exclusively breastfed, could have allergies if the mother consumes an allergenic food (4). However, only about 3% of breastfed infants display such allergies (5). Babies older than 12 months can be allergic to cow milk (6). Hives can appear within a few minutes to a couple of hours after consumption of the allergic food.
- Insect bites and airborne substances can also lead to hives. Allergens commonly found in the air include pollen, the fur of animals, dust, and dust mites. Hives occur as a symptom of the body’s allergic reaction to foreign substances.
- Drug reactions caused due to certain medicines induce an allergic reaction, thus causing skin hives. Examples of such medications are penicillin, phenobarbital, and sulfonamide (8). According to the American Academy of Pediatrics (AAP), only 10% cases of skin hives are caused by a drug reaction.
- Cold-induced hives are a result of low temperatures. Hives may appear on the part of the body that has been exposed to cold wind, snow, or ice-cold water. Older infants may develop hives around lips after eating an ice cream. The reasons for the condition are not known (10).
- Sunlight-induced hives can develop on every part of the body that was exposed to direct sunlight. Such hives are called solar urticaria. It is speculated that the condition is caused by the skin’s reaction to the ultraviolet light (12).
According to the AAP, reasons are unknown for about 30% cases of skin hives caused in infants (13). However, skin hives can be easily identified at home.
What Do Hives Look Like In A Baby?
When looking for skin hives, check for the following symptoms on the baby’s skin.
- Presence of welts: Welts are small mosquito-like bite bumps in different parts of the body. It is the classic symptom of hives; most associated with the condition.
- Display of wheals: The skin develops wheals, a broad raised bump of pink or reddish tone. The skin is blotched with these patches that are predominantly concentrated around the back, leg, neck, and face.
- Wheals and welts change shape: Patches caused by hives would change shape randomly, from a few millimeters to several centimeters. Some hives may be elongated, shaped like a worm.
- Change in locations: The rashes would appear and disappear over a short period.
- Itchiness and fussiness: The hives rash would often itch, causing irritation and discomfort to the baby and making him fussy.
Take your baby to the doctor even on the slightest signs of hives as it is good to get a medical opinion.
How Are Skin Hives Diagnosed?
A doctor would diagnose hives by looking for physical signs, and learning more about baby’s medical history, allergies, and general lifestyle. A blood test could be done to rule out pathogens in the blood. An accurate diagnosis is made after analyzing the report. Treatment follows diagnosis.
How To Treat Hives In Babies?
Hives usually cure on their own without any treatment (14). Nevertheless, a doctor may prescribe a medication to control the symptoms and treat the underlying cause of the condition:
- Antihistamines are a standard prescription medicine administered to bring down the itching and redness caused by hives, and not cure the condition. These medicines are effective, baby-safe, and do not make the little one drowsy. Although they are available over-the-counter (OTC), it is best to consult a doctor before using them.
- Steroids are only prescribed in severe cases, as they have side-effects (15). They are used only in case of chronic hives or when the baby shows no response to antihistamines. Steroids are administered for shorter durations (five days to two weeks) to prevent side-effects.
- Antibiotics and anti-viral medicines do not treat hives, but cure the underlying bacterial or viral infection that has led to hives.
The treatment methods for hives are efficient, but what also works great is the use of home remedies to treat hives in infants.
Are There Home Remedies For Hives In Babies?
Parents can manage hives at home along with the suggested medication. Here are some home remedies to try:
- Cool water baths: Keep the water cool enough to be comfortable, but not cold. Experts recommend the water temperature for baby baths to not be lower than 85°F (29°C) as it may give chills (16). Giving cool baths help wash away potential allergens on the skin (such as pollen) while also relieving itching (17). Use a fragrance-free bath soap or body-wash for the infant. After bath, pat-dry the baby with a towel and use a baby moisturizing lotion for sensitive skin.
- Use cool compresses: Dip sponge or cloth in cool water and apply wherever the baby has itchy skin hives. It provides instant relief from skin irritation caused by itching.
- Dress in loose clothes: Loose clothes help reduce the intensity of friction-induced hives. They prevent sweat-induced hives by facilitating sweat evaporation through air ventilation. Prefer 100% cotton infant clothes over other fabrics.
- Use anti-itch creams: Dermatologists also recommend the use of OTC anti-itch lotion (18). You can also apply calamine lotion that soothes skin irritation. Remember to always use the product as per the manufacturer’s instructions. When in doubt about the usage or unsure of its safety for the infant, consult a pediatrician about the product before using it.
- Trim baby’s nails: Hives can be itchy and repeated itching might exacerbate the condition. Keeping the baby’s nails short as that will reduce the intensity of itching.
Home remedies for hives are simple, but parents can also prevent hives easily.
How To Prevent Hives In Babies?
The risk of hives can be significantly mitigated by observing the following steps:
- Protect the baby from allergens. Keep the baby away from any substance that you know can trigger an allergic reaction. Babies who are allergic to pollen should stay indoors to prevent inhalation of pollen. In the case of sweat-induced hives, keep the baby in a cool environment. Maintain a log of baby’s allergies so that you and other family members are aware of the potential triggers.
- Clean the baby and change his clothes when you come from outside as skin and clothes could trap microscopic pollen and dust that may cause allergy-induced skin hives.
- Maintain favorable temperature and humidity. If it is too hot, then use an air conditioner to control the baby’s sweating. In winters when the weather gets too dry, use a humidifier as it will keep the baby’s skin hydrated. The AAP recommends the use of only cool-mist humidifiers for infants (19).
- Protect the baby from pathogenic infections. Virus and bacteria can induce skin hives. Shield the baby from pathogens by maintaining good hygiene and feeding the baby well for strong immunity.
- Use baby laundry detergent: Potential allergens from regular detergents can linger on the clothes even after a wash. To prevent this, use only baby laundry detergents to wash an infant’s clothes. These detergents are formulated using chemicals that are soft and harmless on a baby’s delicate skin.
Hives in infants may seem tough to manage, but timely treatment and appropriate home remedies help tackle the condition effectively. Prevention is vital and simple. Taking the right steps is the key to keeping the baby’s skin healthy and hives-free.
