Which med causes irregular heartbeat; lyrica, (pregabalin) acutane, valium or zolpidem ? (pvcs)

Zolpidem: I like to use www.Drugs.Com & www.Epocrates.Com to search for drug information. Both are free although latter does require registration. It turns out that palpitations have been associated w/zolpidem so talk to your doc about your concerns. In fact, it's always a good idea to report side effects to your pharmacist & prescribing physician. And reconsider diazepam as it can be addicting.
