Determine Severity of the Allergic Reaction

 
To begin with, understand the severity of your symptoms. Allergic reactions can range from mild to life-threatening. Typical symptoms include:

• Mild Symptoms: hives, redness of the skin, itchiness, or a rash
• Moderate Symptoms: swellings on the body, tightness in the chest, difficulty in breathing, wheezing and sneezing
• Severe Symptoms (Anaphylaxis): rapid pulse, dizziness, change in voice, swelling of the throat and mouth, difficulty breathing, and loss of consciousness
   

Seek Immediate Help

 
If you are experiencing moderate to severe symptoms, don't hesitate to seek immediate medical attention.
 

Take Antihistamines

 
If your symptoms are mild, antihistamines can usually help control them. You might already have these medications if you're aware of your allergy. However, they may cause drowsiness, so use caution if you're driving or operating machinery.
 

Epinephrine Autoinjector

 
If you're at risk for severe allergic reactions, you should carry an Epinephrine autoinjector (EpiPen). If you don't have one, ask a bystander for help. These devices inject a dose of medication to reduce allergic reaction symptoms until you can get to a hospital.
 

Hydrate

 
Do remember to take a considerable amount of water as hydration can help alleviate some symptoms of an allergic reaction.
 

Consult Medical Professionals

 
After such an experience, it is crucial to consult with an allergist. They can provide an exact diagnosis and create a treatment plan to manage your symptoms and help you prevent future reactions.

Consider reaching out to a leading allergy immunotherapy company. They provide tailor-made solutions for allergies, targeting specific allergens, and gradually increasing your tolerance levels over time. They have had impressive results with many patients experiencing a considerable decrease in allergic symptoms and some becoming entirely free of allergies.

Their treatment approach is unique and compatible with both kids and adults. They follow the principle of immunotherapy, a highly recommended form of treatment for allergies which involves giving gradually increasing doses of the allergen to which the person is allergic, eventually diminishing and often eliminating the symptoms.

However, please note that immunotherapy should only be initiated under the supervision of a healthcare provider. This is due to the risk of potential side effects and reactions.

Remember, being vigilant about what foods you consume and understanding their ingredients can significantly prevent allergic reactions.
