An allergic rash is the body's response to a substance that is seen as invading toxin. The result are raised blisters or bumps that cause itchiness and pain. Common allergies include foods, molds and chemicals. It is important to treat a rash as soon as it appears to avoid serious complications.
When your body is exposed to allergens, your immune system releases histamines. These histamines attach themselves to receptors, which makes blood vessels enlarge. Other histamines when attached to receptors will bind and promote redness, itchiness and secretion changes. Antihistamines such as Benadryl, Tavist and Claritin will prevent or lesson the symptoms of allergies. Scratching your rash will actually release more histamines and worsen the itch. Avoid driving after taking antihistamines. These medications are known to cause drowsiness and brain fogginess.
To cool down an itchy rash, apply a moisturizer. Be sure to use one that you've used in the past and know you're not allergic to. Inexpensive lotions can be found at your local drug store. Neutrogena, Cetaphil and Lubriderm use little fragrances and work best on allergic reactions. Hydrocortisone is a steroid cream that is useful for a rash caused by poison ivy. Though it easily relieves skin rashes, it does not affect the internal allergy reaction. Popular creams on the market are Cortizone 10, Cortaid and Aveeno. Hot baths are greatly discouraged during an allergic reaction. Take a quick shower when hives break out in case they are caused by cosmetics, laundry detergent or other chemicals. As an additional precaution, air dry your body or use a hair dryer. Apply cream or lotion and allow to absorb before putting clothes back on.
If you have no prior history of allergic rashes, make a list of possible allergens. Has their been any changes to your diet, cosmetic choice, detergent, cleaning products or physical routine? Sweating opens pores, making it even easier for you to get a rash. Cleaning solvents on gym equipment can give you a reaction. Also, if you have switched detergent, your pores can soak up foreign chemicals. Make a food journal, chronicling your meals and snacks. It is not uncommon to develop a food allergy in adulthood. Schedule an appointment with your physician for an allergy skin test. These tests are able to pinpoint your allergy culprits. Always contact a doctor if symptoms do not improve or get worse. There are many prescription steroid creams that may help like Elocon, Locoid and Westcort. Allergic reactions generally last anywhere from a couple of hours to a few days. It is critical to take them seriously to avoid further damage to your immune system.
