My child found a small round yellowish/tanish circular tablet on the floor of his bedroom and we don't know what it is or where it came from? My in laws stayed in the room a few months ago and they take some medications, but I have vacuumed the room several times since then and never saw it.
It has no imprint or number or markings on it, so I am hoping it is something else. It is not candy, has no flavor and didn't dissolve in water.
Any feedback is appreciated.
No, all pills don't have an imprint, but all OTC and Rx drugs by law are required to have a unique imprint for identification purpose. Vitamins, herbal supps, some diet supps, etc. do not have imprints.
do all pills have an imprint or number on them?
