Benzodiazepines have a high level of cardiovascular, neurologic, and respiratory adverse effects

• A. True
• B. False
• C. Not commonly associated with adverse effects
• D. Only respiratory adverse effects

Answer: (B)

Benzodiazepines are valued in hospital sedation for their anxiolytic and muscle-relaxant effects while generally sparing cardiovascular and respiratory function compared with many other sedatives. The typical adverse effects are neurologic in nature, mainly sedation and ataxia, with dogs and cats sometimes showing mild drowsiness or, less commonly, paradoxical excitement or dysphoria (notably in some cats). Respiratory depression is usually minimal and occurs mainly when benzodiazepines are combined with other central nervous system depressants or given to animals with significant respiratory disease. Cardiovascular effects are uncommon and, when they do occur, are typically mild (such as slight changes in heart rate or blood pressure at high doses or in compromised patients). Because of this relatively favorable safety profile, benzodiazepines are not associated with a high level of adverse effects across cardiovascular, neurologic, and respiratory systems. They do not provide analgesia, so they’re often used alongside analgesics when pain control is needed, and they should be dosed and monitored carefully, especially in stressed or sensitive patients.
