The question of how many azithromycin pills to take in 1 sitting cannot be generalized and needs to be decided specifically based on the amount of azithromycin contained in each pill. Usually for adults, taking azithromycin, a broad-spectrum antibiotic, the maximum daily dose is 0.5 grams, if 1 to 0.25 grams, for example, 1 day can take 2 azithromycin, can be taken at once, that is, 1 day to take 1 time, 1 time to take 2 pills can be treated. Children for upper respiratory tract infections, mycoplasma infections can also choose to apply azithromycin, to 0.25 grams, for example, children can take 1 day can be taken 1 time, 1 time should take 1 pill. However, for obvious cases such as mycoplasma severe infections, it can also be taken twice a day, and 2/3 pills of the normal dose should be taken at one time.
