VS after parenteral route; note muscle rigidity, drug history, hepatic/renal function tests

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

• 
Allergic reactions: rash, urticaria

 

Black Box Warning:

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

 

Black Box Warning:

Headache/migraine:
ABSTRAL, Actiq, Fentora, Lazanda, Onsolis not to be used for this condition; ABSTRAL, Lazanda not to be used in ER; Duragesic TD not to be used for outpatient surgery patients

 

Black Box Warning:

Apnea, respiratory arrest in opioid-naive patients:
do not use ABSTRAL, Actiq, Duragesic, Fentora, Lazanda, Onsolis; opioid-tolerant patients are those using ≥60 mg/day oral morphine, ≥30 mg/day oxyCODONE PO, 8 mg/day HYDROmorphone, 25 mcg TD fentaNYL/hr

Evaluate:

• 
Therapeutic response: induction of anesthesia, relief of breakthrough cancer pain, general pain relief

• 
Cancer pain, general pain relief

Teach patient/family:

• 
About CNS changes: physical dependence; not to use with alcohol, other CNS depressants

 

Black Box Warning:

Accidental exposure:
Discuss the dangers of children or pets ingesting or coming in contact with product

Transdermal route

 

Black Box Warning:

Ambient temperature:
that excessive heat may increase absorption; do not use with heating pads, electric blankets, heat/tanning lamps, saunas, hot tubs, heated waterbeds, when sunbathing

• 
That excessive perspiration may alter adhesiveness

• 
To dispose of patch by placing sticky sides together and flushing down toilet

• 
That patient may need to clip hair before applying to ensure adhesion

• 
May add first aid tape around the edges if there is a problem with adhesion
