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.

A cough lasting 6 months is considered chronic and may be due to conditions such as asthma, chronic bronchitis, acid reflux, post-nasal drip, or, less commonly, infections such as tuberculosis. While your current syrup provides temporary relief by suppressing coughs and reducing allergic reactions, it only masks symptoms rather than treating the underlying cause. You should consult a doctor for a proper evaluation, which may include a chest X-ray and lung function tests, to determine the cause, start appropriate treatment, and prevent any complications.
