[66F] Experiencing dry cough and postnasal drip

Allergic rhinitis is an inflammation of the nasal passages caused by allergens such as pollen, dust, or pet dander. It is different from a common cold, which is caused by a viral infection. Allergic rhinitis typically does not cause fever, while a cold might.

Antihistamines work by blocking the action of histamine, a substance in the body that causes allergy symptoms. They can help reduce sneezing, runny nose, and itching, providing relief from allergic reactions.

Managing postnasal drip can include using nasal saline sprays to rinse the nasal passages, staying hydrated, using a humidifier, and taking medications like antihistamines or nasal corticosteroids to reduce inflammation and mucus production.

If symptoms persist despite treatment, worsen, or significantly impact daily life, it may be beneficial to see an allergist. They can perform tests to identify specific allergens and recommend more targeted treatments or therapies.
