Which of the following is a disadvantage of benzodiazepines?

• A. Sedative effects are not as reliable as the other drugs in high FAS or aggressive patients
• B. They provide no sedation at all
• C. They are never used with alpha-2 agonists
• D. They provide reliable sedation in all cases

Answer: (A)

Benzodiazepines are strong anxiolytics and can help calm many patients, but in animals with high fear–aggression scores they don’t provide predictable, reliable sedation. The sedative effect can be variable: some patients respond with only mild calming, others may remain agitated, or even become paradoxically excited. That inconsistency is the key drawback in stressful, aggressive patients, making benzodiazepines less reliable as a sole sedative in Fear Free protocols. Because of this, they’re typically used as adjuncts to other sedatives (often in combination with alpha-2 agonists or dissociatives) to achieve adequate calm and handling, rather than as the only agent. Additionally, they do not provide analgesia, which further supports using them in multimodal plans rather than relying on them alone.
