Introduction
A cough is a common symptom of various respiratory illnesses, ranging from the common cold to more severe conditions. While some coughs are mild and self-limiting, others can be persistent and debilitating. Understanding the different types of coughs and their underlying causes is crucial for selecting the appropriate treatment. Dhasedyl, a popular over-the-counter cough suppressant, is effective for specific types of coughs.
Types of Coughs
Coughing can be classified into two main categories:
Productive Cough: This type of cough produces mucus or phlegm, which is expelled from the airways. Productive coughs are generally beneficial as they help clear out irritants and infections from the respiratory tract.
Non-Productive Cough: Also known as a dry cough, this type of cough does not produce any mucus. It is often caused by irritation of the throat or airways and can be triggered by allergies, asthma, or smoking.
Dhasedyl for Which Type of Cough?
Dhasedyl is a cough suppressant that contains dextromethorphan, an ingredient that acts on the cough center in the brain, reducing the urge to cough. It is effective for non-productive coughs but should not be used for productive coughs as it can suppress the beneficial expulsion of mucus.
Key Features of Dhasedyl

Dosing
