Cough is a sudden, forceful expulsion of air that helps clear any mucus or irritant in the throat or airways. If it happens more frequently, due to an underlying disease or an allergy, it can be bothersome. Benadryl Syrup helps to loosen thick mucus and reduces its stickiness, making it easier to cough out. This makes it easier for air to move in and out. It will also relieve allergy symptoms like watery eyes, sneezing, runny nose or throat irritation and help you carry out your daily activities more easily. Taking this medicine enables you to live your life more freely without worrying so much about things that set off your symptoms.
