Nursing implications

Nursing assessment

• During initial therapy, assess patient at least weekly during first month and frequently thereafter for compliance, effectiveness of treatment plan, and overall patient progress. Once a stable dose is achieved, monthly assessment may be used. Determine absence of medication toxicity, medical, or behavioral adverse effect; responsible handling of medications by patient; compliance with treatment plan including recovery-oriented activities and psychotherapy or other modalities; abstinence from illicit drug use.
• Lab Test Considerations: Monitor liver function test prior to beginning therapy and periodically during treatment.

Potential Nursing Diagnoses

Implementation

• Buprenorphine/naloxone sublingual film and sublingual tablets are not appropriate as an analgesic.
• Can only be prescribed by clinicians who meet qualifying requirements, and who have notified the Secretary of Health and Human Services of their intent to prescribe this product for the treatment of opioid dependence and have been assigned a unique identification number that must be included on every prescription.
• Induction of therapy begins with patient being in a moderate state of opioid withdrawal and receiving buprenorphine for 2–3 days. Once the induction phase is completed, maintenance begins with buprenorphine/naloxone titration.
• Patients receiving buprenorphine/naloxone sublingual tablets may be switched to sublingual film of same dose. Dose adjustments may be required. A Zubsolv 1.4/0.36 tablet is equivalent in terms of buprenorphine content to a Suboxone 2/0.5 sublingual tablet. A Zubsolv 5.7/1.4 tablet is equivalent in terms of buprenorphine content to a Suboxone 8/2 sublingual tablet
• Sublingual: Film: Place film under tongue. If additional film is required for dose, place on opposite side of tongue from first film, minimizing overlap. Keep film under tongue until dissolved (5–7 min); do not chew, swallow, or move after placement.
  • Tablets:Place under tongue until dissolves, about 5 min. Do not cut, chew, or swallow. Do not eat or drink anything until tablet is dissolved.

Patient/Family Teaching

• Instruct patient to take medication as directed. Take missed doses as soon as remembered unless almost time for next dose; do not double doses. Do not take more often than prescribed and consult health care professional before stopping; dose should be ↓ gradually to prevent withdrawal syndrome. Instruct patient to read Medication Guide before starting therapy and with each Rx refill in case of changes. Advise patient to keep medication in a safe place, out of reach of children and protected from being stolen and do not share with others, even if they have the same symptoms. Explain that buprenorphine/naloxone sublingual film may be fatal to children and individuals not tolerant to opioids. Advise patient that selling or giving medication away is against the law.
• To dispose of unused films, remove from foil pouch and drop each film into toilet and flush.
• Caution patient of the danger of taking non-prescribed benzodiazepines or other CNS depressants, including alcohol, during therapy.
• May cause dizziness. Caution patient to avoid driving and other activities requiring alertness until response to medication is known.
• Advise patient to make position changes slowly to prevent orthostatic hypotension.
• Advise female patients to notify health care professional if pregnancy is planned or suspected, or if breastfeeding.
• Instruct patient to inform family that, in the event of an emergency, treating health care professionals should be informed that patient is physically dependent on an opioid and being treated with buprenorphine/naloxone sublingual film.

Evaluation/Desired Outcomes

• Maintenance treatment of opioid dependency.
