  • Hepatotoxicity: Severe, and sometimes fatal, hepatoxicity has been reported. Discontinue immediately if signs and symptoms of hepatitis occur.
  • Central nervous system effects, including convulsions, anxiety, confusion, depression, and insomnia may occur after the first dose. Use with caution in patients with known or suspected disorders that may predispose them to seizures or lower the seizure threshold.
  • Clostridium difficile-associated colitis: evaluate if diarrhea occurs.
  • Peripheral neuropathy: discontinue if symptoms occur in order to prevent irreversibility.
