Since your cough has continued for two weeks despite taking cough syrup, antibiotics, and painkillers, it would be wise to stop self-medication and consult a doctor for a proper examination. A dry cough is often caused by viral infections, allergies, or acid reflux, so antibiotics like ciprofloxacin may not help if there is no bacterial cause. A doctor can assess your symptoms and suggest more appropriate treatment, such as an inhaler or a different type of cough suppressant, once the underlying cause is identified. In the meantime, staying well hydrated and using honey or steam inhalation may help to soothe the irritation.
