Opioid Side Effects: What You Need to Know Before Taking These Medications

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

They can lead to dependence, breathing problems, and even life-threatening overdose if not used carefully.

And if you’ve been taking them for more than a few weeks, quitting cold turkey isn’t safe. You need medical help. opioid addiction, a chronic condition where someone keeps using opioids despite harm to their health, relationships, or job doesn’t mean you’re weak.

Even over-the-counter cough syrups with codeine can cause these issues if used too long. And mixing opioids with alcohol, sleep aids, or anxiety meds? That’s how accidental overdoses happen. The CDC says most opioid deaths involve more than one drug. You don’t need to be a heavy user to be at risk.
