INTERACTIONS

 
Avoid use with MAOIs; unpredictable reactions may occur

Increase:
effects with other CNS depressants—alcohol, opiates, sedative/hypnotics, antipsychotics, skeletal muscle relaxants

NURSING CONSIDERATIONS
Assess:

• 
Pain:
type, location, intensity before and 30-60 min after administration; titrate upward with 25%-50% until 50% of pain reduced; need for pain medication by pain sedation scoring, physical dependency

• 
Bowel status; constipation is common, may need laxative or stool softener

 
Withdrawal reactions
in opiate-dependent individuals: PE, vascular occlusion; abscesses, ulcerations, nausea, vomiting, seizures; low potential for dependence

• 
CNS changes:
dizziness, drowsiness, hallucinations, euphoria, LOC, pupil reaction

• 
Allergic reactions: rash, urticaria

• 
Respiratory dysfunction: respiratory depression,
character, rate,
rhythm; notify prescriber if respirations are <10/min

Perform/provide:

• 
Storage in light-resistant area at room temp

Evaluate:

• 
Therapeutic response: decrease in pain without respiratory depression

Teach patient/family:

• 
To report any symptoms of CNS changes, allergic reactions

• 
That physical dependency may result from long-term use; low potential for dependency

• That withdrawal symptoms may occur: nausea, vomiting, cramps, fever, faintness, anorexia, profuse sweating, twitching; without treatment symptoms resolve in 5-14 days, chronic abstinence syndrome may last 2-6 mo

• 
To avoid CNS depressants, alcohol

• 
To avoid driving, operating machinery if drowsiness occurs

TREATMENT OF OVERDOSE:

Naloxone (Narcan) 0.2-0.8 mg IV, O

, IV fluids, vasopressors
