<s>[INST] I was diagnosed with the flu and bronchitis 5 days ago.  I was put on Tamiflu and Z-Pak and was told that I would be better by today.  Today, I am still very sick.  Im so tired, nauseated, severe headache and horrible cough that keeps me up most the night.  Im on my 4th day of meds out of 5 days and I just wanted to know if this is normal and how much longer should it be before I feel myself again.  I have two small kids and have been in the bed for 7 days now and have to get better soon! [/INST] Thanks for your question on Chat Doctor. I can understand your concern. You are not improving because you are not taking correct treatment for bronchitis. Best treatment for bronchitis is inhaled treatment. So better to consult pulmonologist and get done clinical examination of respiratory system and PFT (Pulmonary Function Test).PFT will tell you about severity of the disease and treatment is based on severity only. You will mostly improve with inhaled bronchodilators (formoterol or albuterol) and inhaled corticosteroid (ICS) (budesonide or fluticasone). Usual recovery time is 1-2 weeks. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks. </s>
