Frequently Asked Questions (FAQs)

^

Q: What is an expectorant? Is Guaifenesin an effective expectorant?

  • An ‘expectorant’ is any medicine that expels the sputum (phlegm or mucus) from your airways to outside by way of cough
  • Productive or chesty cough (cough with sputum) results when secretions of the airways are increased due to viral or bacterial infections or dust, pollen, or other allergies. The secretions will mix with other cells and substances in the airways and congest the airways causing tightness in chest, problematic breathing, and cough. The body wants to expel these secretions by way of cough. Guaifenesin thins down the secretions and increases cough by way of which it will relieve the congestion of the airways
