I recently discovered that there's a connection between azelastine and throat infections. As an antihistamine, azelastine is often used to treat allergy symptoms like sneezing, itching, and runny nose. However, some people may experience side effects like a sore throat or throat infection due to the use of this medication. It's important to monitor your symptoms and consult with your healthcare provider if you suspect a throat infection. Overall, while azelastine can provide relief for allergy sufferers, it's essential to be aware of potential side effects and address them appropriately.
