**Are auditory hallucinations a side effect of Gabapentin or Oxycodone?** 

A friend in her 30's had surgery 2 weeks ago, and so she has been prescribed some medicine to manage her pain. She took Oxycodone several times the day of and after her surgery and then Gabapentin for the following days. On the fourth day of recovery, while in her apartment where she lives alone, she heard a deep man's voice say clearly and directly (as she reports) in her ear, "Get Out!" 

She called me in tears and deeply disturbed because nothing like that has happened to her... and she was superstitious and afraid it was caused by... (well, something else). I tried to logically reassure her it was probably a side effect of her pain meds she's taking for her surgery, but I am not a doctor and have no idea so she should call her doctor if she has concerns. Yadda, yadda, yadda.

But anyway, **Would Oxycodone be in her system 2 days later? Enough to cause auditory hallucinations?** I know Gabapentin is a pain med that focuses on the brain, but from what I've [read from the FDA][1], auditory hallucinations are a very rare side effect, **but with remnant Oxycodone still in the body's system, could it cause auditory hallucination?**

So basically... **Could Oxycodone taken 2 days prior cause an auditory hallucination?** 

*(Not asking to diagnosis my friend's case -- just wondering, in general, about how long Oxycodone could be in a person's system to cause auditory hallucinations? And if Gabapentin when taken a few days following Oxycodone, can cause auditory hallucinations?)*
