As the influence of barbiturates about the metabolism of phenytoin is just not predictable, phenytoin and barbiturate blood stages really should be monitored additional usually if these medications are provided concurrently.
If inducer is discontinued, think about oliceridine dosage reduction and check for signs of respiratory despair.
