    May cause CNS depression; may impair physical or mental abilities; patients should use caution when performing tasks requiring mental alertness, including operating heavy machinery or driving

    Use should be accompanied by appropriate fluid and electrolyte therapy, when indicated; if severe dehydration or electrolyte imbalance present, drug should be withheld until appropriate corrective therapy initiated; drug-induced inhibition of peristalsis may result in fluid retention in intestine, which may further aggravate dehydration and electrolyte imbalance

    Use with extreme caution in patients with advanced hepatorenal disease and in all patients with abnormal liver function; hepatic coma may be precipitated

    There are no adequate and well-controlled studies in pregnant women; drug should be used during pregnancy only if anticipated benefit justifies potential risk to fetus

    Exercise caution when drug is administered to nursing woman, since physicochemical characteristics of major metabolite, diphenoxylic acid, are such that it may be excreted in breast milk and since it is known that atropine is excreted in breast milk
