Post-Marketing Adverse Events
The following adverse events have been identified during post-approval use of Ultane (sevoflurane USP). Due to the spontaneous nature of these reports, the actual incidence and relationship of Ultane to these events cannot be established with certainty.
- Seizures - Post-marketing reports indicate that sevoflurane use has been associated with seizures. The majority of cases were in children and young adults, most of whom had no medical history of seizures. Several cases reported no concomitant medications, and at least one case was confirmed by EEG. Although many cases were single seizures that resolved spontaneously or after treatment, cases of multiple seizures have also been reported. Seizures have occurred during, or soon after sevoflurane induction, during emergence, and during post-operative recovery up to a day following anesthesia.
- Cardiac arrest
- Cases of mild, moderate and severe post-operative hepatic dysfunction or hepatitis with or without jaundice have been reported. Histological evidence was not provided for any of the reported hepatitis cases. In most of these cases, patients had underlying hepatic conditions or were under treatment with drugs known to cause hepatic dysfunction. Most of the reported events were transient and resolved spontaneously.
- Hepatic necrosis
- Hepatic failure
- Malignant hyperthermia
- Allergic reactions, such as rash, urticaria, pruritus, bronchospasm, anaphylactic or anaphylactoid reactions
- Transient elevations in glucose, liver function tests, and white blood cell count may occur as with use of other anesthetic agents.
