How to treat allergies and hay fever
- Allergy shots: Allergy shots involve exposing you to small amounts of allergens and then slowly increasing the amount over time to desensitize your body to the allergen. The treatment course begins with weekly shots and gradually moves to monthly shots. Sublingual allergy shots, a tablet form of allergy shots, may also be given to treat allergies.
- Medications: Medications such as leukotriene inhibitors can be beneficial in blocking the immune cells released by the body when exposed to allergens. Inhalers may also help ease allergy symptoms.
- Epinephrine auto-injector: For life-threatening allergies, you may need to carry an epinephrine auto-injector.
Your physician may develop a treatment plan based on:
- Severity of symptoms
- Allergen triggers
- Medical needs
Avoiding the trigger is the initial step of the treatment course. Other treatment options may include:

Common Allergies: Symptoms and SignsWhat are allergies? Pollen, food, perfumes, and many more things can provoke allergy symptoms. Allergies are an overreaction of the immune system where the body's defenses react to certain allergens. Learn about common allergy triggers and how you can avoid an allergy attack.
Allergy (Allergies)An allergy refers to a misguided reaction by our immune system in response to bodily contact with certain foreign substances. When these allergens come in contact with the body, it causes the immune system to develop an allergic reaction in people who are allergic to it. It is estimated that 50 million North Americans are affected by allergic conditions. The parts of the body that are prone to react to allergies include the eyes, nose, lungs, skin, and stomach. Common allergic disorders include hay fever, asthma, allergic eyes, allergic eczema, hives, and allergic shock.

Allergy ShotsAllergy shots are given to increase your tolerance to allergens that cause allergy symptoms. At the beginning, allergy shots will be administered once or twice a week for several months. The dose is increased each time until a maintenance dose is reached. Side effects of allergy shots include itchy eyes, shortness of breath, runny nose, tight throat, redness, swelling, and irritation.
Allergy Treatment Begins at HomeAvoiding allergy triggers at home is one of the best ways to prevent allergy symptoms. Controlling temperature, humidity, and ventilation are a few ways to allergy-proof the home. Cleaning, vacuuming, and using HEPA air filters also helps control allergies.
Hay Fever (Allergic Rhinitis)Hay fever (allergic rhinitis) is an irritation of the nose caused by pollen and is associated with the following allergic symptoms: nasal congestion, runny nose, sneezing, eye and nose itching, and tearing eyes. Avoidance of known allergens is the recommended treatment, but if this is not possible, antihistamines, decongestants, and nasal sprays may help alleviate symptoms.

How to Differentiate Between the Signs and Symptoms of COVID-19, Allergies, Cold, and Flu?Coronavirus disease or COVID-19 is an infectious disease caused by a newly discovered coronavirus called SARS-CoV-2. Most people with COVID-19 will experience a mild to moderate respiratory illness and recover without the need for intensive or special treatment. Serious illness is more likely in elderly people and those with underlying medical conditions such as heart disease, diabetes, chronic respiratory disease, and cancer.
Sinus Infection vs. AllergiesBoth sinus infections and allergies (allergic rhinitis) cause symptoms such as runny or stuffy nose and fatigue. Sinus infection (known as sinusitis) is inflammation of the sinuses, caused by infection from bacteria, viruses, and/or fungi (molds). Allergic rhinitis occurs when certain allergies cause nasal symptoms. When a person with allergies breathes in an allergen, such as pollen, dust, or animal dander, symptoms such as runny or stuffy nose, itching, sneezing, and fatigue occur.
Skin Test for AllergyAn allergy skin test helps identify triggers for one's allergic reactions. Small amounts of allergy-provoking substances (allergens) are scratched into the skin. Redness and swelling develop if one is allergic to the substance. A positive allergy skin test implies that the person has an IgE antibody response to that substance. The test is rapid, simple, and relatively safe.
What Are Typical Allergy Symptoms?Allergy symptoms differ depending on the type of allergy and body part involved. For example, food allergies may cause different symptoms than nasal allergies or eye allergies. The severity of symptoms may also vary, ranging from mild irritation to a life-threatening reaction called anaphylaxis.
What Are Typical Seasonal Allergy Symptoms?Typical seasonal allergy symptoms include a stuffy or runny nose, sneezing, coughing, watery eyes, congestion, and a sore throat.
