It could be brought on by a cold, the flu, allergies, or throat irritants and cause a tickling or itchy feeling in the throat. Delodryl syrup relieves an itchy throat and suppresses a strong dry cough. In addition, it lessens allergy symptoms like runny nose, sneezing, and watery eyes. You can manage your dry cough in addition to taking Delodryl Syrup by gargling with warm salt water and consuming ginger or honey.
