It sounds frustrating to have a persistent cough despite completing two courses of antibiotics and Bro-Zedex syrup. Since your cough returns after stopping treatment, it may indicate an underlying issue that needs further evaluation rather than just symptomatic treatment.

• Your current medicines include Azithromycin (an antibiotic) and Bro-Zedex syrup, which contains expectorants and bronchodilators to help clear mucus and ease breathing.
• Persistent cough after antibiotics could suggest causes like unresolved infection, inflammation, asthma, or other lung conditions.
• I recommend seeing a pulmonologist (lung specialist) for a thorough assessment. They may suggest tests such as a chest X-ray, sputum culture, or lung function tests to identify the cause.
• Avoid self-medicating further antibiotics without a doctor’s advice, as inappropriate use can lead to resistance or side effects.
• Meanwhile, keep hydrated, avoid irritants like smoke, and monitor for any worsening symptoms such as fever, breathlessness, or chest pain.

Please consult a pulmonologist promptly to get a precise diagnosis and appropriate treatment tailored to your condition. If you experience severe symptoms like difficulty breathing or high fever, seek emergency care immediately.To narrow down potential causes, we will need some more information.Please tell me your age and gender.
