From the Halifax Daily News:
Health Canada issues warning sedative bottle may contain additional drug
Health Canada is advising consumers taking the sedative Novo-Lorazem to check their bottles for pills of a different shape and size, after being alerted that certain bottles of the drug may also contain Novo-Glyburide, an oral hypoglycemic.

Novo-Glyburide is generally prescribed to diabetics to lower blood sugar. Use of this drug by non-diabetics, or by diabetics already taking other medications for this purpose, could severely lower blood sugar and, in rare cases, result in coma or death, Health Canada warned.
