We are offering Dhasedyl SyrupA cough medicine (or linctus, when in syrup form) is a medicinal drug used in an attempt to treat coughing and related conditions. For dry coughs, treatment with cough suppressants (antitussives) may be attempted to suppress the body's urge to cough. However, in productive coughs (coughs that produce egm), treatment is instead attempted with expectorants (typically guaifenesin, in most commercial medications) in an attempt to loosen mucus from the respiratory tract.
