What databases are available to visually identify oral medication found without packaging? Are there different databases for US, European, Far East, etc?
There are several "pill identifiers" available online:
You enter the shape and color of a pill and any imprints and you get the pictures with drug names.
There are apps for mobile phones:
You take a photo of a pill and you get the info.
Or you go to a search engine and type "recognize my pill" in or so.
ResourcePharm.com has a page: "Identify Foreign Medicines" with links to lists of drugs in various countries.
