Yes you can Dr., I have had this nagging non-stop cough since 06-15-12 and I went in to the walk in clinic today and the PA of my regular doctor prescribe Benzonatate 100mg Capsules for the cough, what happenes if the pills runs and I still have the cough, what do I do?
Thanks for your question on Chat Doctor. I can understand your concern. If you are still coughing after 15 days of benzoate then consult pulmonologist and get done 1. Clinical examination of respiratory system 2. Chest x-ray 3.  PUT (Pulmonary Function Test). PFT is needed to rule out bronchitis. Chest x-ray is needed to rule out lung infection. You may need antibiotic, Inhaled bronchodilators and inhaled corticosteroid (ICS) according to the diagnosis. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
