Opana ER tablets are the extended-release version of Oxymorphone that belongs to the opioid medication class and approved for medical use in the United States (U.S) in 1959. Being a scheduled medication, health authorities distribute Opana ER under a restricted program known as the Opioid Analgesic REMS (Risk Evaluation and Mitigation Strategy) program. You can either get the medicine from a chemist shop near you or buy Opana ER online via a legitimate online store that’s too without stepping outside your place.
