Prescription Pain Medications (Opioids)

When opioids enter the brain, they attach to molecules on cells known as opioid receptors. These receptors are located in many areas of the brain and body, especially areas involved in feelings of pain and pleasure, as well as a part of the brain that regulates breathing.

Opioids affect the brain's "reward circuit," causing euphoria (the “high”) and flooding the brain with the chemical messenger dopamine. Surges of dopamine in the reward circuit encourage you to continue pleasurable but unhealthy behaviors like taking drugs, leading you to repeat the behavior again and again. Repeated surges from drug-taking can lead to addiction.

Yes, you can overdose and die from prescription opioid misuse. In fact, taking just one large dose could cause the body to stop breathing.

Deaths from overdoses of prescription drugs have been increasing since the early 1990s, largely due to the increase in misuse of prescription opioid pain relievers. More than 17,000 people died from an overdose of a prescription pain medication in 2017. The risk of overdose and death increases if you combine opioids with alcohol or other medications that also slow breathing, such as benzodiazepines (e.g. Xanax^®). Among all age groups, males are more likely to overdose from prescription pain medicines than are females.¹ Learn more about drug overdoses in youth.

Signs of Overdose

Signs of a possible prescription opioid overdose are:

• slow breathing
• blue lips and fingernails
• cold damp skin
• shaking
• vomiting or gurgling noise
• looking like you have passed out---or with a nodding head going in and out of consciousness

People who are showing symptoms of overdose need urgent medical help (call 911 immediately). A drug called naloxone can be given to reverse the effects of an opioid overdose and prevent death—but only if it is given in time.

Naloxone is available as an easy-to-use nasal spray called Nasal Narcan^® or autoinjector with the brand name Ezvio^®. It is often carried by emergency first responders, including police officers and emergency medical services. In some states, doctors can now prescribe naloxone in advance to people who use prescription opioids or to their family members, so that in the event of an overdose, it can be given right away without waiting for emergency personnel (who may not arrive in time).

Yes, prescription opioids can be addictive. People who misuse prescription opioids are at greater risk of becoming addicted to opioids than people who take them as prescribed by a doctor. They often continue to take the drug simply to avoid painful withdrawal symptoms.

Opioid withdrawal can cause:

• restlessness
• muscle and bone pain
• sleep problems
• diarrhea
• vomiting (throwing up)
• cold flashes with goosebumps (“cold turkey”)
• leg movements

Doctors, dentists and other health care providers who prescribe opioids know how to weigh the risks of opioid dependence and addiction against the benefits of the medication.  Patients should communicate any issues or concerns to their doctor as soon as they arise. The earlier a problem is identified, the better the chances are for long term recovery. Learn more about dentists and prescription opioid medications.

If you, or a friend, are in crisis and need to speak with someone now: 

• Call the National Suicide Prevention Lifeline at 1-800-273-TALK (they don't just talk about suicide—they cover a lot of issues and will help put you in touch with someone close by)

If you want to help a friend, you can:

• Share resources from this site, including this page.
• Point your friend to NIDA's Step by Step Guide for Teens and Young Adults. 
• Encourage your friend to speak with a trusted adult.

If a friend is using drugs, you might have to step away from the friendship for a while. It is important to protect your own mental health and not put yourself in situations where drugs are being used.
