Dry cough after a cold is caused by cold irritation and respiratory system infection during the cold. Dry cough can be treated with Cefaclor dispersible tablets, as well as Beidougen capsule, oral solution of Ambroxol hydrochloride, and powerful loquat. You can also take green olive tablets to help moisten your throat and prevent coughing. In addition, pay attention to keeping the living environment clean and hygienic, open windows and ventilate regularly, and stay away from pollen, dust, second-hand smoke and cold air that can easily cause allergies. Keep the room moist and not overly dry. You can also eat more vegetables and fruits, such as spinach, tomatoes, cucumber, bitter melon, duck pear, loquat, etc., which can help moisten the lungs and stop coughing. Doing good measures to keep warm and avoiding greasy and spicy foods will help recover from dry cough.
