Why Would I See A Ghost Tablet? 

Some pills are broken down after you swallow them and as they travel through your gut. This is the way your gut handles most foods. However, some pills are not broken down in your gut. Similar to the way you can sometimes see corn in your stool, these pills leave ghost tablets.


If I See A Ghost Tablet, Does This Mean The Pill Didn’t Work?

If you see a ghost tablet, it doesn’t mean the pill didn’t work. Think of ghost tablets like sponges that have been wrung out. The medicine has been “wrung out” of the pill by your body. But the ghost tablet, like a sponge, stays intact.
