Oxycodone 10 mg is a prescription opioid used to treat moderate to severe pain. It can cause drowsiness, dizziness, nausea, constipation, and slowed breathing. Because it can lead to dependence, misuse, or overdose, it should only be taken exactly as prescribed. Combining oxycodone with alcohol, benzodiazepines, or other sedatives can dangerously suppress breathing and may be fatal.
