Answer

Thanks for your post.

Unless you actually see pill fragments in the vomit, there's no need to redose-- this usually only happens within 10-15 minutes of swallowing the pill. Rifampin typically gives body fluids (saliva, tears, urine and yes, even vomit) a red color. This color doesn't necessarily mean that there's pill in the vomit.

I hope this is helpful. BY
