Which of the following is a Pain Medication/Narcotics (Controlled)?

• A. Tresederm
• B. Acepromazine
• C. Trazodone
• D. Fentanyl (Sublimaze)

Answer: (D)

Narcotic analgesics are controlled substances used to manage pain, and their regulatory status is a key part of safe veterinary practice. Fentanyl is a potent opioid analgesic used to relieve severe pain and is classified as a Schedule II controlled substance in the United States. Because of its high potency and risk of respiratory depression and dependence, it requires strict handling, secure storage, and thorough recordkeeping, along with proper prescribing and inventory controls (often with DEA registration and routine audits). It can be given injectable or as a transdermal patch, making it a common option for acute or perioperative pain management in animals.

The other medications listed do not function as narcotic analgesics. Tresederm is a topical anti-inflammatory preparation, Acepromazine is a tranquilizer/sedative, and Trazodone is an antidepressant used for behavior modification or sedation. Therefore, fentanyl is the correct choice as the Pain Medication/Narcotic (Controlled).
