Doc - I ve been diagnosed with renal cancer and it has spread to my lungs. My oncologist is using Votrient as a treatment. A couple to the side effects are stomach pain (like a cramp) and insomnia. My sleep pattern has been reversed. As a pain reliever and sleep air my oncologist prescribed Oxycodone and Acetaminophen (Percocet) 5mg/325mg. I was reading on-line that the pill should be taken whole, and not divided. I read this information after I cut the pill in half and took it. The article said taken the pill other than whole releases the Oxycodone faster and could result in death. Any advice?????
