Compliance
Issues

Noncompliance can be an issue1

As you know, many patients fail to comply with the full course of a prescribed medication, and studies show this holds true for influenza therapies as well.2,3 With Rapivab® (peramivir injection), you can be assured that a full course of influenza therapy is delivered to patients in your care.4

Uncomplicated influenza

Rapivab provides the assurance of a full course of flu treatment in the hospital emergency department (ED), urgent care center, or clinic.4

Did You Know...

Almost one-third of patients stop taking their medicine earlier than instructed.2

Medication adherence is also a challenge in children. Some barriers to adherence in children include inaccurate dose measurements of an oral suspension, misunderstanding of administration instructions, or forgetfulness of the parent or caregiver. The use of non-oral routes of medication administration can add to possible barriers to adherence. For example, inhaled medications pose additional issues such as inadequate technique or difficult administration.5

Comorbidities

Rapivab’s single IV dose guarantees compliance.

Did You Know...

Nonadherence may be due to psychological problems, cognitive impairment, inadequate follow-up or discharge planning, or lack of belief in treatment.2

65+ compliance concerns

Rapivab may help ensure treatment compliance despite forgetfulness, dementia, Alzheimer’s, or polypharmacy.

Instead of a trip to the pharmacy and multicourse or multiday therapy, patients may prefer a single 15- to 30-minute intravenous (IV) infusion.4

Important Safety Information  

RAPIVAB® (peramivir injection) Important Safety Information

Indication

RAPIVAB is indicated for the treatment of acute uncomplicated influenza in patients 2 years and older who have been symptomatic for no more than 2 days.

Limitations of Use

  • Efficacy of RAPIVAB is based on clinical trials of naturally occurring influenza in which the predominant influenza infections were influenza A virus; a limited number of subjects infected with influenza B virus were enrolled.

  • Influenza viruses change over time. Emergence of resistance substitutions could decrease drug effectiveness. Other factors (for example, changes in viral virulence) might also diminish clinical benefit of antiviral drugs. Prescribers should consider available information on influenza drug susceptibility patterns and treatment effects when deciding whether to use RAPIVAB.

  • The efficacy of RAPIVAB could not be established in patients with serious influenza requiring hospitalization.

Contraindications

RAPIVAB is contraindicated in patients with known serious hypersensitivity or anaphylaxis to peramivir or any component of the product. Severe allergic reactions have included anaphylaxis, erythema multiforme and Stevens-Johnson Syndrome.

Warnings and Precautions

  • Rare cases of serious skin reactions, including erythema multiforme, have been reported with RAPIVAB in clinical studies and in postmarketing experience. Cases of anaphylaxis and Stevens-Johnson Syndrome have been reported in postmarketing experience with RAPIVAB. Discontinue RAPIVAB and institute appropriate treatment if anaphylaxis or a serious skin reaction occurs or is suspected. The use of RAPIVAB is contraindicated in patients with known serious hypersensitivity or anaphylaxis to RAPIVAB.

  • Influenza can be associated with a variety of neurologic and behavioral symptoms that can include events such as hallucinations, delirium, and abnormal behavior, in some cases resulting in fatal outcomes. There have been postmarketing reports (from Japan) of delirium and abnormal behavior leading to injury in patients with influenza who were receiving neuraminidase inhibitors, including Rapivab. Because these events were reported voluntarily during clinical practice, estimates of frequency cannot be made, but they appear to be uncommon. These events were reported primarily among pediatric patients. The contribution of Rapivab to these events has not been established. Patients with influenza should be closely monitored for signs of abnormal behavior.

  • Serious bacterial infections may begin with influenza-like symptoms or may coexist with or occur as complications during the course of influenza. Rapivab has not been shown to prevent such complications.

Adverse Reactions

The most common adverse reaction in adults (18 years of age and older) was diarrhea (8% Rapivab vs 7% placebo). Lab abnormalities (incidence ≥2%) occurring more commonly with Rapivab than placebo were elevated ALT 2.5 times the upper limit of normal (3% vs 2%), elevated serum glucose >160 mg/dL (5% vs 3%), elevated CPK at least 6 times the upper limit of normal (4% vs 2%), and neutrophils <1.0 x 109/L (8% vs 6%). In a subset of subjects with serious influenza requiring hospitalization treated with RAPIVAB 600 mg as monotherapy (N=101), the following adverse reactions were also reported more frequently with RAPIVAB as compared to placebo: constipation (4% versus 2%), insomnia (3% versus 0%), AST increased (3% versus 2%), and hypertension (2% versus 0%).

The safety profile of RAPIVAB in subjects 2 to 17 years of age was generally similar to that observed in adults. Specific adverse reactions reported in pediatric subjects treated with RAPIVAB (occurring in ≥2% of subjects) and not reported in adults included vomiting (3% versus 9% for oseltamivir), fever and tympanic membrane erythema (2% versus 0%, respectively, for each of these events). The only clinically significant laboratory abnormality (DAIDS Grade 2) occurring in ≥2% of pediatric subjects treated with RAPIVAB was proteinuria by dipstick analysis (3% versus 0% for oseltamivir).

Concurrent Use with Live Attenuated Influenza Vaccine

Antiviral drugs may inhibit viral replication of a live attenuated influenza vaccine (LAIV) and thus may reduce vaccine efficacy). The concurrent use of Rapivab with LAIV intranasal has not been evaluated. Because of the potential for interference between these two products, avoid use of Rapivab within 2 weeks after or 48 hours before administration of LAIV unless medically indicated.
