Assess for possible sexual dysfunction.Depression
Assess mental status (orientation, mood, and behavior) frequently.
» Assess for suicidal tendencies, especially during early therapy. Restrict amount of drug available to patient. Risk may be increased in children, adolescents, and adults ≤24 yr.

Assess location, duration, intensity, and characteristics of pain before and periodically during therapy. Use pain scale to assess effectiveness of medicine.Lab Test Considerations
Assess CBC and renal and hepatic function before and periodically during therapy. Slight, clinically insignificant ↓ in leukocyte and neutrophil counts may occur.
Potential Nursing Diagnoses
Ineffective coping (Indications)
Sexual dysfunction (Side Effects)
Do not confuse trazodone with tramadol.
: Administer with or immediately after meals to minimize side effects (nausea, dizziness) and allow maximum absorption of trazodone. A larger portion of the total daily dose may be given at bedtime to decrease daytime drowsiness and dizziness.
» Oleptro should be administered on an empty stomach at bedtime and swallowed whole or broken along scored lines; do not chew or crush.
Instruct patient to take medication as directed. If a dose is missed, take as soon as remembered. Do not take if within 4 hr of next scheduled dose; do not double doses. Oleptro should be taken at bedtime. Consult health care professional before discontinuing medication; gradual dose reduction is necessary to prevent aggravation of condition. Advise patient to read Medication Guide prior starting therapy and with each Rx refill in case of changes.
May cause drowsiness and blurred vision. Caution patient to avoid driving and other activities requiring alertness until response to drug is known.
Caution patient to change positions slowly to minimize orthostatic hypotension.
