Roxicodone is a brand name for generic oxycodone. It's used to treat moderate to severe pain, and it's often prescribed in combination with other drugs, like acetaminophen or hydrocodone. Roxicodone is available OTC (over-the-counter), and you can get it without a prescription from your local pharmacy. Oxycodone is also available in other forms, such as tablets or an oral solution (shots). You can buy oxycodone online without a prescription if you're 18 years old or older and don't have any health conditions that would prevent you from buying the drug. However, if you have a history of drug abuse or addiction, talk to your doctor before taking any medication at all!
