ZIS DS 100 ml is a cough and cold syrup designed to provide effective relief from symptoms associated with common cold, flu, and allergic rhinitis. This formulation typically combines dextromethorphan (a cough suppressant), paracetamol (for fever and pain relief), and chlorpheniramine (an antihistamine for relieving allergic symptoms such as sneezing and runny nose). It helps alleviate cough, nasal congestion, and fever, making it an ideal solution for managing the discomfort caused by colds and upper respiratory infections.
