I have been taking tramadol and gabapentin and now got oxycodon can i take together or space them apart thanks?

You must talk carefully with the person who's prescribed these medications so that you can understand if they are safe for your medical conditions. They are strong medications and should be taken very carefully.

You do not reveal why you are taking 2 analgesics and the gabapentin. The effect of all three could be additive drowsiness and dizziness, and, if you have sleep apnea, could promote cerebral suppression nocturnally. So, there must be careful monitoring. Would advise NO driving, use of power equipment. Need to discuss all of this with the doctor who is handling, as they know you.
