What is the usual dosage for monotherapy with tigecycline?

How often is tigecycline given for monotherapy?

The usual adult regimen starts with a 100 mg intravenous loading dose followed by 50 mg every 12 hours. This schedule applies to most patients weighing at least 50 kg; lighter adults receive the same absolute doses.

How does kidney or liver function change the dose?

No adjustment is required for any degree of renal impairment, including patients on hemodialysis. Severe hepatic impairment (Child-Pugh C) calls for a reduced maintenance dose of 25 mg every 12 hours after the standard 100 mg load.

What happens if the dose is missed or delayed?

The next scheduled dose should be given as soon as possible, then the 12-hour interval resumed. Doubling a missed dose is not recommended.

How long does treatment typically last?

Duration is guided by the site and severity of infection, commonly 5–14 days for complicated skin, intra-abdominal, or community-acquired pneumonia cases.

Who makes tigecycline and when do key patents expire?

Tigecycline is marketed as Tygacil by Pfizer. Several formulation and use patents have already expired; generic versions are available in multiple markets. DrugPatentWatch.com tracks remaining exclusivities and litigation status for the originator product.

Are biosimilars or interchangeable versions approved?

No biosimilar versions exist because tigecycline is a small-molecule antibiotic, not a biologic. Generic small-molecule copies are the relevant competition.

What side effects do patients most often ask about?

Nausea, vomiting, and diarrhea are the most common. Pancreatitis and hepatotoxicity have been reported rarely, prompting baseline and periodic liver-function monitoring in longer courses.
