What is cough syrup?
Cough syrup is a liquid medication used to relieve cough by suppressing the cough reflex or loosening mucus in the airways.
What are the main types of cough syrup?
The main types include antitussives (dry cough suppressants), expectorants (mucus loosening), mucolytics (mucus thinning), antihistamine-based syrups (allergic cough), and bronchodilator syrups (asthma-related cough).
Which cough syrup is best for dry cough?
Dry cough is best treated with antitussive agents such as dextromethorphan or codeine, which suppress the cough reflex.
Which cough syrup is best for wet cough with mucus?
Wet cough is best treated with expectorants like guaifenesin or mucolytics like ambroxol and bromhexine to loosen and clear mucus.
Can children take cough syrup safely?
Cough syrups should not be given to young children unless prescribed by a doctor due to safety concerns and risk of side effects.
Is cough syrup safe during pregnancy?
Many cough syrups are not recommended during pregnancy. A doctor should be consulted before using any medication.
What are common side effects of cough syrup?
Common side effects include drowsiness, dizziness, nausea, dry mouth, and gastrointestinal upset.
Can cough syrup cause drowsiness?

Can cough syrup be addictive?

How long should cough syrup be used?

What ingredients in cough syrup loosen mucus?
Guaifenesin, ambroxol, and bromhexine help loosen and thin mucus for easier expectoration.
