The dose of cephalosporin per capsule per day should not be generalized, but should be analyzed according to the specific conditions of the patient. For patients with mild disease, such as adults and children weighing 30kg or more, 0.1g can be taken twice/day, which is 0.2g for the whole day. In addition, for patients with severe illness, 0.2g can be taken orally twice/day, which is the daily dose of 0.4g for the whole day for patients with severe illness. However, for children weighing less than 30kg, the dose can be calculated and given according to the kilogram weight, that is, 1.5-3.0mg per kilogram weight, and can be given twice a day.
