I have not taken any of those medications but I would suggest not taking anything that was not prescribed for you without your doctor's order.
Prozac (fluoxetine) and Lyrica (pregabalin) (Moderate Drug-Drug)
MONITOR: Central nervous system- and/or respiratory-depressant effects may be additively or synergistically increased in patients taking multiple drugs that cause these effects, especially in elderly or debilitated patients.
MANAGEMENT: During concomitant use of these drugs, patients should be monitored for potentially excessive or prolonged CNS and respiratory depression. Ambulatory patients should be counseled to avoid hazardous activities requiring complete mental alertness and motor coordination until they know how these agents affect them, and to notify their physician if they experience excessive or prolonged CNS effects that interfere with their normal activities.
Dilaudid (hydromorphone) and Lyrica (pregabalin) (Moderate Drug-Drug)

Here is some information pertaining to the possible reactions...though I don't advocate taking any one elses prescription medication. You should speak with a pharmacist or your physician about the safety concerns.
Take care.
