I have been using 15 mg of oxycodone 3 times a day for 4 years for my condition, I have a pretty complicated case of ulcerative colitis and have several flares during each month. This medication is prescribed. This month was very bad and I took more than I should and I have 10 days before I can get my script. What can I do to help in the meanwhile? I have Gabapentin, Xanax, clonanazepan,hydroxyzine Pamoate. Please let me know what I can do because I do not want to go into withdrawl, I hear it is horrible. I also do not want to end up in the hospital. Thanks to anyone that can help.
