Could mixing gabapentin, xanax, (alprazolam)zoloft,ketoralac,oxycodone, together cause death? my daughter was prescribed these and died the next morning.

Sorry for your loss: Only post mortem toxicology can answer this question for sure, but too much of any of these could be fatal, especially Xanax (alprazolam) and oxycodone as both can suppress breathing in high doses. If they were taken only as prescribed, it would be safe, but something added like alcohol could also be fatal. Again, my deepest condolences.

Drug interactions: I am so sorry for your loss. The drugs you describe can have significant interactions which may result in excessive sedation and depression of the respiratory system. Overdose of narcotic ( oxycodone) by itself could cause respiratory depression that could be fatal.

I am so sorry that: you have lost a child. This combination of medications would have to be managed very carefully & one would need to be mindful of possible drug interactions. Using Xanax with Oxycodone may cause central nervous system depression. Depending on the amounts that she ingested this could cause respiratory distress, coma,or death. Overdoses of just one of specific medications she took could lead to
