Generally, the course of azithromycin infusion is 3-5 days, up to 5 days for children and up to 7 days for adults. Azithromycin is a macrolide antibiotic that acts as a bacterial inhibitor by inhibiting the synthesis of bacterial proteins and can be used to treat a variety of bacterial, mycoplasma or chlamydial infections. The course of treatment varies when treating different diseases and cannot be generalized. In general, infusions should be given for a maximum of 5 days for pediatric patients and no more than 7 days for adults, but should be adjusted according to the recommendations of the treating physician. If the disease is not yet controlled and the drug needs to be continued, a second course of infusion can also be continued. Because azithromycin is hepatotoxic, it should be used with caution in patients with hepatic insufficiency. If allergic or gastrointestinal adverse reactions occur during the infusion, the drug needs to be discontinued and managed by a medical professional.
