Allergic Rashes

If you have allergies, allergic rashes are very common. A rash is typically not the most severe reaction you can have, but it may happen along with other things like hives and swelling. Allergic rashes may happen due to ingestion, but most allergic rashes come from direct contact with an allergen. You may not have allergies, but there are certain things that we are all allergic to. Poison ivy is one of those things. The skin seems fragile, but it is thick and tough. It protects us against bacteria and germs. When an allergen contacts the skin, your body instantly creates a reaction to it. The rash will eventually go away, but it is best to get treatment.

Allergic reactions are not always the same, and not everyone has allergies to the same thing. Your skin is the largest organ of the body. It protects the body against many things. It works in conjunction with the immune system. Allergens are either hereditary or acquired. In most cases, allergens develop early in childhood. Your body learns what is harmful and what is not. Things that are not even harmful to you may be recognized as harmful by the body. Once an allergen touches the skin, the body reacts with IgE antibodies. These antibodies create a chemical reaction that irritates the skin and causes rashes.

There are many different causes of allergic rashes. Environmental things like pollen can rest on the skin and create a rash. Certain plants like poison ivy also create rashes. Jewelry, fragrances, and makeup can react with your skin and create a chemical reaction leading to a rash. Other sources are:

  • Latex
  • Soap
  • Lotion
  • Cleaning products
  • Medication

You may not initially be allergic to something but over time, you can develop an allergy. The body may not even respond to allergens immediately. Sometimes it takes some time for a rash to appear. Once a rash appears, you will experience symptoms.

Symptoms of Allergic Rashs

When you develop a rash, it will look red and become very itchy. It may be accompanied by swelling. There are several types of rashes which all may bring about different symptoms. Sometimes allergic rashes are itchy. Other times they peel. They do not always look the same. You can develop flat raised bumps or small tiny bumps all over. Rashes are sometimes hard to diagnose yourself. Understanding the different types of rashes will allow you to know what to expect and if you need to go to the doctor.

Eczema is one type of allergic rash. Eczema is also called atopic dermatitis. It is very common, and it makes your skin sensitive to certain lotions and soaps. It is very itchy and the more you scratch it, the worse it becomes. It can bleed and become easily infected. Contact dermatitis is a result of an allergen that comes in contact with the skin directly. Contact dermatitis may result in blisters and a lot of burning. The sun tends to worsen contact dermatitis. It may even cause it. Hives are another type of rash characterized by swollen red welts on the skin. They typically last a lot longer than other types of rashes. Latex allergies tend to instantly cause rashes. Your body reacts almost like it would to poison ivy. If you have a latex allergy, you know. As soon as latex touches you, you react to it. Rashes from latex tend to go away soon after you are no longer exposed to it.


Allergic rashes are not hard to diagnose. The problem is finding the source of the rash. The doctor will do a skin test. The doctor will expose you to different things. If you are allergic to them, you will instantly develop a rash. When skin tests are not conclusive, you may have to do a blood test.


The best way to avoid allergic rashes is to stay away from the allergen. If you notice a rash, you can usually treat yourself. Calamine lotion is a great method of treatment for rashes. You can even take oral antihistamines. These drugs suppress the histamines and prevent the spread of the rash as well as treats the rash. If the rash is serious, you may need antibiotics to treat the problem. When you bathe, you should use products for sensitive skin. Maybe even medicated products. If your rash occurs along with wheezing and difficulty breathing, you may be having a severe allergic reaction. Anaphylaxis can happen in conjunction with rashes. If you feel that you are experiencing a severe reaction, you need to seek medical attention.

Allergic rashes are not always serious, but it can be, especially in conjunction with anaphylaxis. Sometimes it is hard to identify the source of the problem when you do not have a reaction immediately. If you notice you are having rashes, you should find an allergist and allow them to test you for allergens. Allergies are no fun, but if you can avoid allergens altogether, you will not have to worry about rashes or any other type of allergic reaction.
