Contra Indications

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

Precautions

Serious skin reactions reported including erythema multiforme and Stevens-Johnson syndrome; discontinue and initiate appropriate treatment (see Contraindications) Influenza can be associated with neurologic and behavioral symptoms including hallucinations, delirium, and abnormal behavior, in some cases resulting in fatal outcomes

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

Interactions

Adverse Effects
