ETHEX and FDA notified heathcare professionals of a nationwide recall of a single lot of Hydromorphone HCl 2 mg Tablets due to potential for oversized tablets. Hydromorphone is a drug used for pain management. If someone were to take a higher than expected dose of Hydromorphone, the risk of adverse effects known to be associated with the drug may be increased, including respiratory depression (difficulty or lack of breathing), low blood pressure, and sedation. The recalled tablets are a blue, round tablet with a script "E" on one side and a "2" on the other side.
