You can buy OxyContin (oxycodone ER) online from a licensed pharmacy, as long as you have a legitimate prescription. Trying to buy this narcotic drug without a prescription is illegal. Some Web sites may allow OxyContin to be ordered without a prescription. However, in addition to being illegal, these "pharmacies" may also be dangerous (no legitimate pharmacy would sell this product without a prescription).
It is not legal to simply "order" Oxycontin® (oxycodone ER) without a legitimate prescription from a legitimate prescriber (who should only prescribe Oxycontin for a legitimate medical need).
OxyContin is a narcotic opioid (morphine-like) medication. It is classified as a Schedule II controlled substance (the strictest classification for legal medications) in the United States. As such, it is subject to regulation by the Drug Enforcement Administration (DEA). There are strict rules for obtaining OxyContin, and there are strict fines and penalties for selling, using, or trying to buy OxyContin (online or otherwise) without a prescription.
As long as you have a legitimate prescription, OxyContin can be ordered from any licensed pharmacy, including legitimate internet pharmacies that choose to sell controlled substances (some do not). If the pharmacy does not require a prescription, this is a huge warning flag that the pharmacy is not legitimate. The best way to know if an internet pharmacy is legitimate is to make sure it is one of the Verified Internet Pharmacy Practice Sites™ (VIPPS®).
In order to get a legitimate OxyContin prescription, you must have face-to-face contact and a legitimate medical relationship with your prescriber.
Of course, you can also buy OxyContin at your local pharmacy. Either way, make sure your pharmacist (including your online pharmacist) has a complete list of all the medications you take and any medical conditions you may have.
