Interaction Details
Oritavancin Diphosphate is classified as belonging to the following category: Antibiotic Drugs
Theoretically, antibiotics might interfere with the metabolism of flaxseed constituents, which could potentially alter the effects of flaxseed.
Some potential benefits of flaxseed are thought to be due to its lignan content. Secoisolariciresinol diglucoside (SDG), a major lignan precursor, is found in high concentrations in flaxseed. SDG is converted by bacteria in the colon to the lignans enterolactone and enterodiol. Antibiotics alter the flora of the colon, which could theoretically alter the metabolism of flaxseed.

Oritavancin Diphosphate Overview
-
Oritavancin injection is used to treat skin infections caused by certain types of bacteria. Oritavancin is in a class of medications called lipoglycopeptide antibiotics. It works by killing bacteria.

Antibiotics such as oritavancin will not work for colds, flu, and other viral infections. Using antibiotics when they are not needed increases your risk of getting an infection later that resists antibiotic treatment.
