Which medication is commonly prescribed for allergic rhinitis?

Antihistamines are commonly prescribed for allergic rhinitis because they directly target the symptoms associated with this condition. Allergic rhinitis, often caused by allergens such as pollen, dust mites, or animal dander, leads to the release of histamine in the body. Histamine is a chemical that contributes to inflammation and symptoms such as sneezing, itching, runny nose, and congestion. Antihistamines work by blocking the action of histamine at its receptor sites, thereby alleviating these symptoms effectively.

In addition to providing symptom relief, antihistamines can be found in various formulations, including non-drowsy options, which make them suitable for use during daytime activities. This versatility and effectiveness in managing allergy symptoms are why they are a common choice for treating allergic rhinitis.
