A dry cough, especially after travelling to a polluted environment like Delhi, is commonly caused by viral infections or environmental allergies. Olfi-Pod 200/200 is a very potent combination of two strong antibiotics (Cefpodoxime and Ofloxacin). Antibiotics do not cure viral infections or allergic coughs. Unless your doctor has diagnosed a specific, severe bacterial infection (often indicated by fever or thick sputum), this high-strength medication is likely unnecessary and inappropriate for a simple dry cough. I recommend consulting your doctor to re-evaluate your prescription and discuss safer, symptomatic treatments like cough suppressants, anti-allergics, or steam inhalation.
