Opana ER is an FDA-approved prescription medication used to manage severe, around-the-clock pain in patients requiring long-term opioid treatment. It contains oxymorphone, a potent opioid analgesic that works by altering the way the brain and nervous system respond to pain. Due to its strength and extended-release formulation, patients often seek to buy Opana ER online or order Opana ER online from licensed, reputable pharmacies. Some may look to purchase Opana ER online overnight for fast and discreet delivery. However, Opana ER should only be used under strict medical supervision and with a valid prescription due to its high risk for misuse and addiction.
