Clonazepam
Neuro/Psych-Increased risk of cognitive impairment, delirium, falls, fractures, and motor vehicle crashes. Long half-life benzodiazepines are generally not preferred in the elderly. Limit dose to 1.5mg/day. Pulmonary- Use caution in patient with compromised respiratory function. General-May be appropriate for select indications including severe generalized anxiety disorder and seizure disorder.

- Taking clonazepam with opioid medications (such as codeine, hydrocodone) may increase your risk of very serious side effects, including death. To lower your risk, your doctor should have you take the smallest dose of clonazepam that works, and take it for the shortest possible time. Get medical help right away if any of these very serious side effects occur: slow/shallow breathing, unusual lightheadedness, severe drowsiness/dizziness, difficulty waking up.
