What are the effects of rifampin on stool color?

Rifampin can cause stool to appear orange or reddish in color. This change occurs because rifampin is excreted in bile and can alter the color of bodily fluids. While this discoloration is usually harmless, it can sometimes cause concern for patients if they are unaware of this side effect. It's important to inform healthcare providers of any unusual changes in stool color while taking rifampin.
