Drug interactions
|
Morphine, fentanyl, midazolam and other CNS depressants may have an additive effect with phenobarbital in causing respiratory depression. Consider starting phenobarbital at the lower end of the dose range in these patients. Blood concentrations of digoxin, metronidazole, corticosteroids (e.g. betamethasone, dexamethasone), vitamin D, and beta-blockers (e.g. propranolol, sotalol) may be reduced if administered concurrently with phenobarbital. Concurrent administration of phenytoin with phenobarbital has variable effects on serum concentrations of either drug. Serum concentrations should be monitored for both drugs.
