A dry throat can be quite the uncomfortable thing to deal with. Many affected individuals also experience coughing and difficulty swallowing, and depending on the cause of their dry throat, potentially fever, nausea, vomiting, headaches, and body aches as well. For the most part, the most common causes of a dry throat include mouth breathing, snoring, and the common cold or similar illness. Some may also experience this condition due to allergies, exposure to irritants like air pollution or smoke, sleep apnea, as well as dry air.
As stated, allergies are a very common cause of dry throat and are usually accompanied by other symptoms such as a stuffy nose, sneezing, itchy and watery eyes, and a cough. These symptoms are generally caused by an immune system reaction to certain elements in the air, such as pollen or pet dander. Antihistamines block the allergic reaction caused by these elements and are a great way to combat dry throat and other symptoms due to allergies. Antihistamines can be purchased over-the-counter but if dry throat and other allergy symptoms are severe a prescription may be obtained from a physician.
