            Cautions

            Volatile liquid; use appropriate vaporizer for inhalation

            Agitation/delirium may occur

            Postoperative hepatitis reported

            Closely monitor patients with anemia, hepatic impairment, myxedema, renal impairment

            Can induce malignant hyperthermia in genetically susceptible individuals

            Advise patients that performance of activities requiring mental alertness, such as driving or operating machinery, may be impaired after sevoflurane anesthesia

            Reports of QT prolongation, associated with torsade de pointes (in exceptional cases, fatalities reported); exercise caution when administering to susceptible patients (eg, congenital long QT syndrome, coadministration with drugs that prolong QT interval)

            Should not be used as a sole agent of induction in patients with ventricular dysfunction

            Risk of perioperative hyperkalemia in pediatric patients reported (rare); some resulting in cardiac arrhythmia and death

            Bradycardia in Down syndrome

            • Episodes of severe bradycardia and cardiac arrest, not related to underlying congenital heart disease, reported during anesthesia induction with sevoflurane in pediatric patients with Down syndrome
            • In most cases, bradycardia improved with decreasing concentration of sevoflurane, manipulating the airway, or administering an anticholinergic or epinephrine
            • During induction, closely monitor heart rate, and consider incrementally increasing the inspired sevoflurane concentration until a suitable level of anesthesia is achieved
            • Consider having an anticholinergic and epinephrine available when administering sevoflurane for induction in this patient population

            Perioperative hyperkalemia

            • Inhaled anesthetics associated with rare increases in serum potassium levels that have resulted in cardiac arrhythmias and death in pediatric patients postoperatively
            • Patients with latent as well as overt neuromuscular disease, particularly Duchenne muscular dystrophy, appear to be most vulnerable
            • Concomitant use of succinylcholine has been associated with most, but not all, of these cases
            • Elevated serum creatinine kinase levels and, in some cases, changes in urine consistent with myoglobinuria observed
            • Despite similar presentation to malignant hyperthermia, none of affected patients exhibited signs or symptoms of muscle rigidity or hypermetabolic state
            • Early and aggressive intervention to treat hyperkalemia and resistant arrhythmias recommended
            • Evaluation for latent neuromuscular disease recommended

            Malignant hyperthermia

            • In susceptible individuals, volatile anesthetic agents, including sevoflurane, may trigger malignant hyperthermia, a skeletal muscle hypermetabolic state leading to high oxygen demand; fatal outcomes reported
            • The risk of developing malignant hyperthermia increases with concomitant administration of succinylcholine and volatile anesthetic agents; therapy can induce malignant hyperthermia in patients with known or suspected susceptibility based on genetic factors or family history, including those with certain inherited ryanodine receptor (RYR1) or dihydropyridine receptor (CACNA1S) variants
            • Signs consistent with malignant hyperthermia may include hyperthermia, hypoxia, hypercapnia, muscle rigidity (eg, jaw muscle spasm), tachycardia (eg, particularly that unresponsive to deepening anesthesia or analgesic medication administration), tachypnea, cyanosis, arrhythmias, hypovolemia, and hemodynamic instability; skin mottling, coagulopathies, and renal failure may occur later in the course of the hypermetabolic process
            • Successful treatment of malignant hyperthermia depends on early recognition of clinical signs
            • If malignant hyperthermia is suspected, discontinue all triggering agents (eg, volatile anesthetic agents and succinylcholine), administer intravenous dantrolene sodium, and initiate supportive therapies; consult prescribing information for intravenous dantrolene sodium for additional information on patient management
            • Supportive therapies include administration of supplemental oxygen and respiratory support based on clinical need, maintenance of hemodynamic stability and adequate urinary output, management of fluid and electrolyte balance, correction of acid-base derangements, and institution of measures to control rising temperature

            General anesthetics and sedation drugs in young children and pregnant women

            • Brain development
              • Prolonged or repeated exposure may result in negative effects on fetal or young children’s brain development
              • Caution with use during surgeries or procedures in children younger than 3 yr or in pregnant women during their third trimester
              • Assess the risk:benefit ratio in these populations, especially for prolonged procedures (ie, >3 hr) or multiple procedures

            Pregnancy & Lactation

            Pregnancy

            There are no adequate and well-controlled studies in pregnant women; in animal reproduction studies, reduced fetal weights were noted following exposure to 1 MAC sevoflurane for three hours a day during organogenesis

            There are no data on pregnancy exposures in primates corresponding to periods prior to the third trimester in humans Sevoflurane has been used as part of general anesthesia for elective cesarean section in women; there were no untoward effects in mother or neonate; the safety of sevoflurane in labor and delivery has not been demonstrated

            Lactation

            The concentrations of sevoflurane in milk are probably of no clinical importance 24 hours after anesthesia; because of rapid washout, sevoflurane concentrations in milk are predicted to be below those found with many other volatile anesthetics

            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.
