Hi, Thanks for posting in HCM. I understand your concern. Azee 500 contains azithromycin , which is used to treat a wide variety of bacterial infections. It is a macrolide-type antibiotic. Common side effects associated with its intake include: stomach upset, loose stools, nausea, vomiting and/or abdominal pain. So what you are experiencing could be side effect of the intake of the antibiotic. Kindly take Lactobacillus in the form of tablet or powder. You can also consume probiotics. Along with it take B-complex vitamin once a day for 15 days. Keep yourself well hydrated by consuming enough quantity of liquids. Gradually, your symptoms should subside and you should be back to normal. Hope the information provided would be helpful. All the best.
