Get to know your Opana® ER tablets

Since its approval in 2006, Opana® ER has been used to treat patients with moderate to severe chronic pain from conditions such as chronic lower back pain and osteoarthritis.

The Opana ER tablet has gone through some changes. In 2011, Opana ER was available in a tablet shape that was “biconvex,” or raised and rounded on both sides. There may be limited quantities of both the biconvex tablets of Opana ER and the octagonal original formulation tablets available through your local pharmacy.

Moving forward, the tablet shape will be "biconcave," or indented on both sides. While the tablet may look different, it’s still the same medicine.

The Opana ER tablets are in the chart below. You can also print this information.
