• 
Ext rel products
(Ryzolt/Utram ER) are not interchangeable

• 
Do not break, crush, or chew ext rel product

• 
With antiemetic for nausea, vomiting

• 
When pain is beginning to return; determine dosage interval by patient response

• 
With or without food; ER: always give with food, or always give on empty stomach

SIDE EFFECTS

CNS:
Dizziness, CNS stimulation, somnolence, headache, anxiety, confusion, euphoria,
seizures,
hallucinations, sedation,
neuroleptic-malignant-syndrome–like reactions

CV:
Vasodilation, orthostatic hypotension, tachycardia, hypertension, abnormal ECG

EENT:
Visual disturbances

GI:
Nausea, constipation, vomiting, dry mouth, diarrhea, abdominal pain, anorexia, flatulence,
GI bleeding

GU:
Urinary retention/frequency, menopausal symptoms, dysuria, menstrual disorder

INTEG:
Pruritus, rash, urticaria, vesicles, flushing

SYST:
Anaphylaxis, Stevens-Johnson syndrome, toxic epidermal necrolysis,
serotonin syndrome

PHARMACOKINETICS

Rapidly and almost completely absorbed, steady state 2 days, peak 1.5 hr, duration 6 hr, terminal half-life 7.9-8.8 hr, may cross blood-brain barrier, extensively metabolized, 30% excreted in urine as unchanged product, protein binding 20%

INTERACTIONS

• 
Inhibition of norepinephrine and serotonin reuptake: MAOIs; use together with caution

Increase:
CNS depression—alcohol, sedatives, hypnotics, opiates

 
Increase:
serotonin syndrome—SSRIs, SNRIs, serotonin-receptor agonists

Increase:
traMADol levels—CYP3A4 inhibitors (aprepitant, antiretroviral protease inhibitors, clarithromycin, danazol, delavirdine, diltiazem, erythromycin, fluconazole, FLUoxetine, fluvoxaMINE, imatinib, ketoconazole, mibefradil, nefazodone, telithromycin, voriconazole)

Decrease:
traMADol effects—CYP3A4 inducers (barbiturates, bosentan, carBAMazepine, efavirenz, phenytoins, nevirapine, rifabutin, rifampin)

Decrease:
levels of traMADol—carBAMazepine

Drug/Herb

• 
Avoid use with St. John’s wort

Increase:
CNS depression—chamomile, hops, kava, skullcap, valerian

Drug/Lab Test

Increase:
creatinine, hepatic enzymes

Decrease:
Hgb

NURSING CONSIDERATIONS
Assess:

• 
Pain:
location, type, character, give before pain becomes extreme

• 
Respiratory depression:
withhold if respirations <12/min

• 
I&O ratio: check for decreasing output; may indicate urinary retention

• 
Need for product; dependency

• 
Bowel pattern; for constipation, increase fluids, bulk in diet

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

• 
Hypersensitivity:
usually after beginning treatment

• 
Increased side effects in renal/hepatic disease

 
Serotonin syndrome, neuroleptic malignant syndrome:
increased heart rate, shivering, sweating, dilated pupils, tremors, high B/P, hyperthermia, headache, confusion; if these occur, stop product, administer serotonin antagonist if needed

Perform/provide:

• 
Storage in cool environment, protected from sunlight

• 
Assistance with ambulation

• 
Safety measures: side rails, night-light, call bell within easy reach

Evaluate:

• 
Therapeutic response: decrease in pain

Teach patient/family:

• 
To report any symptoms of CNS changes, allergic reactions, serotonin syndrome, seizures

• 
That drowsiness, dizziness, and confusion may occur; to avoid hazardous activities

• 
To make position changes slowly because orthostatic hypotension may occur

• 
To avoid OTC medications, herbs, supplements, CNS depressants and alcohol unless approved by prescriber

• 
Not to discontinue abruptly, taper
