Finding the pill's shell in your stool
The drug seeps out of a hard shell that doesn't dissolve. The label says not to worry if you see it.
“Advise patients not to be concerned if they occasionally notice a tablet-appearing substance in their stool.”
Swallow it whole with liquid, and don't chew or crush it. Tell your doctor about chest pain, fainting or fingers that turn cold or blue.
45 reports to the FDA's adverse event system mention residue of the tablet shell. A report is not proof the drug caused it. See the query
