I'm sorry to hear that your cough and congestion have persisted for 15 days despite taking Novamox CV 625 (an antibiotic) for 5 days. Prolonged cough and congestion can have various causes, including viral infections, bacterial infections not responsive to the antibiotic used, or other respiratory conditions.

Here are some important points to consider:

• Antibiotic Use: Novamox CV 625 contains amoxicillin and clavulanic acid, which target certain bacterial infections. If your symptoms have not improved, it might indicate that the cause is not bacterial or that a different treatment is needed.
• Duration of Symptoms: A cough lasting more than two weeks warrants further evaluation to rule out other causes such as bronchitis, sinusitis, allergies, or less commonly, more serious conditions.
• Next Steps: It is important to see a respiratory specialist or your primary care doctor for a thorough examination. They may recommend further tests such as a chest X-ray or sputum analysis to identify the cause and guide appropriate treatment.

Please seek medical attention promptly to ensure proper diagnosis and management. If you experience worsening symptoms like difficulty breathing, high fever, or chest pain, seek emergency care immediately.To narrow down potential causes, we will need some more information.Please tell me your age and gender. I understand you've been dealing with congestion and a cough for the past 15 days, and Novamox CV 625 didn't help.
