Allergic reaction rashes can appear alarming, but most cases are entirely harmless. If you notice a rash, though, it’s best to consult a doctor to get an accurate diagnosis and rule out severe medical conditions.
Allergic reaction rash is an intensely itchy, red welts on the skin’s surface caused by histamine, an immune chemical in the body, triggered by an allergen, such as a bee sting, food, or drug. You can treat an allergic reaction rash in three ways: a skin cream, a shot, or a pill.
Causes of Allergic Reaction Rash
Raised skin can result from many medical conditions and medications, such as allergic contact dermatitis, irritation from clothing, or exposure to chemicals. Other common triggers of allergic reaction rash include:
Bites and Stings
Insect or spider bites and stings might be uncomfortable, but they are rarely severe, even when they look terrible. They can be painful, though, and they can pack an irritating or dangerous punch of allergic reactions such as:
- Itching
- Redness
- Rashes
- Swelling
If you experience severe itching or discomfort, your doctor may recommend a product to treat rashes and other skin conditions.
Poisonous Plants
Poisonous plants such as poison oak or poison ivy are a common culprit for allergic reaction rash. These allergic rashes can spread to other parts of the body by touching the fluid-filled blisters in the affected area.
Medication
Medical science is full of surprises, and one of such is how drugs intended to treat illnesses or address several medical conditions can sometimes trigger a life-threatening allergic condition.
According to the National Institute of Health (NIH), many over-the-counter and prescription medications can cause allergic reactions in people with drug allergies. These medications include:
- Antibiotics
- Nonsteroidal anti-inflammatory drugs (NSAIDs)
- Neomycin and bacitracin
- Anti-hypertensive pills
- Birth control pills
- Contrast dye
You may experience these reaction rashes immediately you take the medication. In some cases, you may experience delayed reactions a few days or weeks after medication use.
Food
Food allergies are rising among children and adults and are estimated to affect 1 in every 13 people. This potentially life-threatening condition occurs when your immune system reacts to an allergen in some food you eat.
Most people who are allergic to some kinds of foods like eggs, nuts, seafood, and certain fruits, exhibit allergic responses, which can be any or all of the following:
- Skin rash
- Hives and itching
- Swelling.
Chemical Allergen
The potential of a chemical to trigger an allergic response depends on its irritant, sensitizing, and allergic properties. This allergic reaction is caused by exposure to latex and rubber, hair dyes, propylene glycol, and formaldehyde.
In industrial environments, triggers may include environmental tobacco smoke, perfumes, fragrances, diesel, and other chemicals and materials.
Diagnosis
Allergies are challenging to diagnose without understanding the patient’s environment and potential exposure to triggers. Your doctor will examine your medical record and ask you a few questions to aid in proper diagnosis and treatment.
Suppose your doctor is unsure about your diagnosis. In that case, he may order a few tests, such as a punch biopsy or allergy skin tests to rule out any underlying condition that may trigger an allergic attack. Your doctor may ask about recent exposure and the frequency of the attack.
Treatment
Treatment for allergic reaction rash varies depending on the severity of your condition. Your doctor may recommend the following treatment options:
- Corticosteroid creams
- Nonsteroidal creams cream in combination with an ointment
- Steroid medications, such as prednisone
- Epinephrine injection
- Cool compresses
An allergic condition can lead to a severe medical condition in rare instances. Consult your doctor for medical care if you experience recurring allergic attacks.
Conclusion
While one bout of allergic rash is harmless and can go away without specific treatment, recurrent episodes may need medical help.
