Hi I am concerned about a family member who is on a lot of medications. She has copd and other health problems. My concern is the meds...a few that she is on are ambien, Lyrica, Zantex, and Valium, and now some pain meds. She is diabetic, had a hip replacement in February, and brusied ribs from a recent fall. My question is this, Is it safe to take these medications together? Ambien, Lyrica, Zantex, and Valium?
