Based on the information provided, I found no specific recommendations for the dosing intervals of generic tigecycline. However, I was able to gather information about the general administration of tigecycline that can be helpful.

Tigecycline is an antibiotic, and the brand name for tigecycline is Tygacil. It is used to treat various bacterial infections, including complicated skin and skin structure infections, complicated intra-abdominal infections, and community-acquired bacterial pneumonia [3].

According to the sources, the recommended dosage of tigecycline for adults is 100 mg intravenously (IV) every 12 hours on the first day, followed by 50 mg IV every 12 hours [3]. The duration of therapy depends on the type and severity of the infection [3].

It is important to note that the dosing intervals should be adjusted based on the patient's renal function [1]. Specifically, for patients with creatinine clearance less than 30 mL/min, the recommended dosing interval should be extended to 24 hours [1].

In summary, while there are no specific recommendations for the dosing intervals of generic tigecycline, the recommended dosage for adults is 100 mg IV every 12 hours on the first day, followed by 50 mg IV every 12 hours. The dosing intervals should be adjusted based on the patient's renal function.
