INTERACTIONS

 
Increase:
Severe, fatal reactions: MAOIs

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

NURSING CONSIDERATIONS
Assess:

• 
For decreasing output; may indicate urinary retention

 
For withdrawal symptoms in opioid-dependent patients; PE, vascular occlusion, abscesses, ulcerations

• 
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

• 
Need for pain medication, physical dependence

Perform/provide:

• 
Storage in light-resistant container at room temp

• 
Safety measures: night-light, call bell within easy reach, assistance with ambulation, especially for geriatric patients

Evaluate:

• 
Therapeutic response: decrease in pain

Teach patient/family:

• 
To report any symptoms of CNS changes, allergic reactions

• 
That physical dependency may result when used for extended periods

• 
That withdrawal symptoms may occur: nausea, vomiting, cramps, fever, faintness, anorexia

• 
How to use nasal product

• 
To avoid hazardous activities

TREATMENT OF OVERDOSE:

Naloxone HCl (Narcan) 0.2-0.8 mg IV, O
2
, IV fluids, vasopressors
