It needs to be monitored, checked it on the Interactions Checker and this was found:
clonazepam ↔ butalbital
Applies to: clonazepam, Fioricet (acetaminophen/butalbital/caffeine)
MONITOR: Barbiturates may increase the plasma clearance of clonazepam and thereby reduce its clinical effectiveness. Phenobarbital is the only barbiturate specifically implicated in this interaction. However, other barbiturates may behave in a similar fashion. Also, clonazepam may increase the effectiveness of barbiturates. A case of respiratory depression and coma has been reported in a patient receiving high doses of both clonazepam and amobarbital.
MANAGEMENT: If these drugs are used together, close observation for altered clonazepam and barbiturate effects is indicated.
You need to talk to your doc/pharmacist who prescribed the meds, hope this helps?
