Oritavancin and Pregnancy

Tell your doctor if you are pregnant or plan to become pregnant.

The FDA categorizes medications based on safety for use during pregnancy. Five categories - A, B, C, D, and X, are used to classify the possible risks to an unborn baby when a medication is taken during pregnancy.

Oritavancin falls into category C. There are no well-controlled studies that have been done in pregnant women. Oritavancin should be used during pregnancy only if the possible benefit outweighs the possible risk to the unborn baby.

Oritavancin and Lactation

Tell your doctor if you are breastfeeding or plan to breastfeed.

It is not known if oritavancin crosses into human milk. Because many medications can cross into human milk and because of the possibility for serious adverse reactions in nursing infants with use of this medication, a choice should be made whether to stop nursing or stop the use of this medication. Your doctor and you will decide if the benefits outweigh the risk of using oritavancin.

Oritavancin Overdose

If you take too much oritavancin, call your healthcare provider or local Poison Control Center, or seek emergency medical attention right away.

If oritavancin is administered by a healthcare provider in a medical setting, it is unlikely that an overdose will occur. However, if overdose is suspected, seek emergency medical attention.

How is oritavancin given?

Oritavancin is injected into a vein through an IV, and is usually given only one time in a single dose. A healthcare provider will give you this injection.

Oritavancin must be given slowly, and the IV infusion can take at least 3 hours to complete.

This medicine can cause unusual results with certain medical tests for up to 120 hours (5 days) after your injection. Tell any doctor who treats you that you have been treated with oritavancin.

Call your doctor promptly if your symptoms do not improve after receiving oritavancin.
