NURSING CONSIDERATIONS
Assess:

• 
Pain:
intensity, type, location, other characteristics before, 1 hr after giving product; titrate upward by 25% until pain reduced by half; need for pain medication, physical dependence, opioid is more effective before pain is severe

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

• 
B/P, pulse, respirations before, periodically; if respirations <10/min, dose may need to be reduced, oversedation may occur

• 
Bowel status: constipation; provide fluids, fiber in diet, may need stimulate laxatives

• 
Allergic reactions:
rash, urticaria

• 
Cough and respiratory dysfunction: respiratory depression, character, rate, rhythm

• 
History of ulcers if using ibuprofen combination product

Perform/provide:

• 
Storage in light-resistant area at room temp

• 
Safety measures: night-light, call bell within easy reach; assistance with ambulation

Evaluate:

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

• 
To avoid driving, other hazardous activities because drowsiness occurs

• 
To avoid other CNS depressants; they will enhance sedating properties of this product
