Dosage adjustment

• Renal impairment (especially in dialysis patients)


• Hypersensitivity to drug or its components


Use cautiously in:

• renal, hepatic, or cardiac impairment

• psychosis

• pregnant or breastfeeding patients

• Give oral form with or without food.

• Know that patients weighing 44 lb (20 kg) or less should be given oral solution.

• Be aware that injection form is intended for temporary use when oral route isn't feasible.

Be aware that injection form is for I.V. use only and must be diluted before administering.

• Dilute 500 mg/ml in 100 ml 0.9% normal saline injection, lactated Ringer's injection, or dextrose 5% injection. Withdraw 5 ml, 10 ml, or 15 ml for 500-mg, 1,000-mg, or 1,500-mg dose, respectively.

Patient monitoring

• Measure temperature and watch for signs and symptoms of infection.

Monitor neurologic status. Report signs that patient is dangerous to himself or others.

• Instruct patient to swallow extended-release tablets whole and not to chew, break, or crush them.

Advise family to contact prescriber if patient poses a danger to himself or others.

Caution patient not to stop taking drug abruptly, because doing so may increase seizure activity.

• Teach patient and family about adverse CNS reactions, and tell them to report these promptly. Urge them to take safety measures to prevent injury.

• Instruct patient to avoid activities that require mental alertness until CNS reactions are known.

• Inform patient that he'll undergo periodic blood testing during therapy.

• As appropriate, review all other significant and life-threatening adverse reactions and interactions, especially those related to the herbs mentioned above.
