Opioid Side Effects: What You Need to Know About Risks and Management

When you take opioids, a class of powerful pain-relieving drugs that include oxycodone, hydrocodone, morphine, and fentanyl. Also known as narcotics, they work by binding to receptors in your brain and spinal cord to reduce pain signals.
