Hello, If you are having severe side-effects of Oxycodone then you should you consult your physician regarding substituting it with some other analgesic. Since it is an opioid, it is not advisable to stop it suddenly as it may cause severe withdrawal symptoms. Your physician will taper it slowly so that you have fewer symptoms. Hope I have answered your query. Let me know if I can assist you further. Regards, Dr. Nazma Amman
