constipation
"After lower back surgery I was prescribed  Oxycodone for pain and Diazepam ( Valium) for muscle spasms. The only problem is constipation,something that I had never experienced before. The instructions say that it may take up to 72 hours and this is how long it took to work for me. I was sceptical if it was going to work at all but it did. NO pain or any problems. I went easy the only thing the smell is hard to describe. Haha!!!. I took it twice  a day on the advise of the nurse after the single dose didn't bring me any results the first day. Always ask your doctor for stuff like that even though it is an OTC  remedy . Hope you feel better."
