Allergies can be annoying, disruptive and potentially life-threatening. Unfortunately, there is no single perfect medicine that is guaranteed to work for everyone. Depending on the severity of the allergy, different treatments may be necessary. Antihistamines are commonly used to reduce the symptoms of allergies such as sneezing, itching, and runny nose. Other treatments may include anti-inflammatory medications, immunotherapy, or allergen avoidance. A combination of treatments may be recommended depending on the person's individual needs.
