What is the standard tigecycline dosage for infection treatment?

What is the usual tigecycline dose for treating infections?

For infection treatment, the standard tigecycline regimen is a higher loading dose followed by a lower maintenance dose. The typical approach used in practice is:

- 100 mg intravenously as an initial loading dose (often given as 50 mg every 12 hours for the first two doses), then
- 50 mg intravenously every 12 hours thereafter.

This dosing pattern is used to start therapy quickly and then maintain drug levels with the standard twice-daily schedule.

Does the dose change for different types of infections?

Dose changes are not usually based on “infection type” alone; instead, dosing adjustments depend more on patient factors and prescribing guidance for the specific product label. When clinicians adjust tigecycline dosing, they typically consider:
- severity of illness,
- organ function (especially hepatic impairment),
- tolerability (since tigecycline can cause significant adverse effects for some patients).

How is tigecycline given (IV schedule)?

Tigecycline is administered by intravenous infusion on the every-12-hours schedule described above, with the initial loading dose used to reach therapeutic exposure faster.

Important safety note

Tigecycline is associated with clinically important safety considerations, so the exact dosing should follow the prescribing information and the clinician’s judgment for the patient’s condition and risk profile.

If you share the infection being treated (or the tigecycline product/indication you mean), I can help narrow to the most relevant labeled regimen.
