Medications for allergy

Medications for allergies help manage symptoms caused by immune reactions to substances like pollen, dust, or pet dander. Antihistamines, such as loratadine or cetirizine, block histamine — a chemical released during allergic responses — reducing sneezing, itching, and runny nose. Nasal sprays can decrease inflammation inside the nasal passages, providing relief. Decongestants help reduce nasal swelling and congestion but should be used cautiously. For severe allergies, doctors may prescribe corticosteroids or allergy immunotherapy (allergy shots) to decrease sensitivity over time. These medications improve quality of life by alleviating discomfort and controlling symptoms effectively.
