Aerodil LS Expectorant 100 ml is a combination medicine used mainly for the treatment of wet (productive) cough. It is commonly prescribed in conditions like bronchitis, asthma, COPD, and respiratory infections, where there is thick mucus, chest congestion, wheezing, or breathing difficulty. It helps in clearing the airways and improving breathing comfort.

This syrup contains Ambroxol, Guaifenesin, and Levosalbutamol. Ambroxol helps thin and loosen thick mucus, making it easier to cough out. Guaifenesin reduces the stickiness of phlegm and increases fluid in the airways to help mucus removal. Levosalbutamol works as a bronchodilator that relaxes airway muscles and opens the air passages, improving airflow and easing breathing.

Together, these actions provide triple benefit—mucus thinning, mucus expulsion, and airway relaxation. This makes cough more productive and reduces symptoms like chest tightness, congestion, and breathlessness, helping patients recover more comfortably during respiratory illness.

Common side effects may include nausea, vomiting, stomach discomfort, dizziness, headache, tremors, and increased heart rate, which are usually mild and temporary. It should be used only under medical supervision, especially in children, and is not suitable for dry cough.
