Thanks for your question on Healthcare Magic. I can understand your concern. Yes, you can give her Azithromycin. No harm in it.. Most common cause for bronchitis is infection. Azithromycin being a broad antibiotic, helps in infection. So you can give her Azithromycin. About homeopathic syrup you are talking about, in my opinion, you should avoid it. Better to give her allopathic syrupy for bronchitis. These homeopathic drugs are not tested under clinical trials so their safety is always in doubt. So better not to try them in children. Instead of this, you can safely give allopathic syrup as these drugs are time tested and proven safe in various clinical studies. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
