Reduced Allergic Symptoms: Reduced or eliminated symptoms such as sneezing, runny nose, congestion, and itchy eyes. Over time, the injections can help desensitise the immune system to specific allergens, leading to a decrease in the severity of symptoms.

Long-Term Relief: Unlike some other allergy medications, hay fever injections provide long-term benefits. They may be recommended for individuals with persistent or severe allergic symptoms and have not responded well to other treatments.

Prevention of Asthma Development: Allergen immunotherapy has been shown to reduce the risk of developing asthma.

Decreased Reliance on Medications: People undergoing hay fever injections may experience a decrease in the need for allergy medications over time. This can lead to a reduced reliance on antihistamines, nasal corticosteroids, and other allergy drugs.

Improvement in Quality of Life: By reducing the frequency and severity of allergic symptoms, hay fever injections can contribute to better sleep, increased productivity, and a greater ability to participate in outdoor activities without discomfort.

Preventive Effects: Hay fever injections may have a preventive effect, meaning they can prevent the development of new allergies or sensitivities.
