Can Allergies Cause a Fever?

Regardless of the season, you can have allergic reactions to various things. Allergic reaction occurs when the immune system reacts negatively towards a foreign substance that does not cause a reaction in other people, such as a bee sting, pet fur and pollen grains. During such a reaction, the immune system will produce antibodies to fight against the foreign substances, which are basically harmless to the body. An allergic reaction can manifest in various ways, including inflammation of the digestive system, sinuses or the skin.

The misconception of allergies causing fever may be because some of the symptoms associated with allergic reactions are similar to those of some viral respiratory infections. Such symptoms include Nasal Congestion, cough, watery eyes and runny nose.

However, if the fever persists or is accompanied by other symptoms, it is advisable that you see a physician. Additionally, you may also need to keep a log of youractual temperatures. The doctor will use such information to rule out any other underlying medical condition and prescribe the appropriate cure.

Treatment for Allergies
With the answer to "Can allergies cause a fever?" being a no, you should also know the proper treatment for allergies symptoms. There are various treatment options that may be used to treat allergic reactions, some of which are mentioned below:


1. Staying Away From the Allergen
As long as you are in contact with the allergen, your body will continue to manifest symptoms of an allergic reaction. With the help of your doctor, you should identify the allergen that is causing a reaction in your body, hence stay away from it. This is the initial step in curing the symptoms and preventing their recurrence.


2. Immunotherapy
When other remedies fail, your doctor may recommend immunotherapy to combat allergic reactions. This is particularly the case with severe allergic reactions. The therapy may involve injection of a purified form of the allergen over a span of time, usually a couple of years. Alternatively, allergen immunotherapy may be administered in the form of a tablet, which is placed beneath the tongue and allowed to dissolve. In other cases, sublingual drugs may be used to remedy pollen-related allergies.


3. Medications to Combat Symptoms
Depending on the causal agent, there are various medications that may be administered to alleviate symptoms of the allergic reaction. In this case, you may use either prescription drugs or over the counter drugs in the form of eye drops, oral medications or nasal sprays.


4. Emergency Epinephrine
If your allergic reactions to a certain allergen are always severe, the doctor may give you an emergency epinephrine shot to be carrying along with you every time. The shot should be administered the moment you are exposed to the allergen. The shot is meant to ease the symptoms until you get to the hospital for emergency treatment.
