The major hazards of hydromorphone include dose-related respiratory depression and sometimes circulatory depression. More common side effects include light-headedness, dizziness, sedation, itching, constipation, nausea, vomiting, and sweating.
1 Combined use of muscle relaxants or benzodiazepines and oxycodone may lead to increased respiratory depression.  Since oxycodone causes constipation, the use of antidiarrheals, for example, diphenoxylate (Lomotil) and loperamide (Imodium), in persons taking oxycodone, can lead to severe constipation.
