General disorders and administration site conditions: Anaphylactic/anaphylactoid reactions
Psychiatric: Abnormal behavior, hallucination
Warnings
Contraindications
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
Cautions
Serious skin reactions reported including erythema multiforme and Stevens-Johnson syndrome; discontinue and initiate appropriate treatment
Influenza can be associated with neurologic and behavioral symptoms including hallucinations, delirium, and abnormal behavior, in some cases resulting in fatal outcomes; postmarketing surveillance has reported delirium and abnormal behavior leading to injury in patients receiving neuraminidase inhibitors
Serious bacterial infections may begin with influenza-like symptoms or may coexist with or occur as complications during the course of influenza; peramivir has not been shown to prevent such complications
Drug interaction overview
- Inactivated influenza vaccine: May administered at any time relative to use of peramivir
- Live attenuated influenza vaccine (LAIV; intranasal): Antiviral drugs may inhibit viral replication and reduce vaccine efficacy; avoid LAIV within 2 weeks before or 48 hr after peramivir unless medically indicated
Pregnancy & Lactation
Pregnancy
Limited available data with use in pregnant women are insufficient to determine a drug- associated risk of adverse developmental outcomes; there are risks to the mother and fetus associated with influenza in pregnancy
Animal studies
-
Administered during organogenesis in rats
- Dose 8 x human recommended dose
- Single IV bolus injection: No adverse effects observed
- Continuous IV infusion: Reduced renal papilla and dilated ureters were observed
-
Administered in rabits
- Administration of drug during organogenesis at exposures 8 times those in humans at recommended dose resulted in developmental toxicity (abortion or premature delivery) at a maternally toxic dose
Lactation
There are no data on presence of drug in human milk, effects on breastfed infant, or on milk production; drug is present in rat milk limited clinical data during lactation preclude a clear determination of risk of therapy to an infant during lactation; therefore, developmental and health benefits of breastfeeding should be considered along with mother’s clinical need for therapy and any potential adverse effects on breastfed child from drug or from underlying maternal condition
Pregnancy Categories
A: Generally acceptable. Controlled studies in pregnant women show no evidence of fetal risk.
B: May be acceptable. Either animal studies show no risk but human studies not available or animal studies showed minor risks and human studies done and showed no risk. C: Use with caution if benefits outweigh risks. Animal studies show risk and human studies not available or neither animal nor human studies done. D: Use in LIFE-THREATENING emergencies when no safer drug available. Positive evidence of human fetal risk. X: Do not use in pregnancy. Risks involved outweigh potential benefits. Safer alternatives exist. NA: Information not available.Pharmacology
