Prescription opioids are medications that are chemically similar to endorphins – opioids that our body makes naturally to relieve pain. They are also similar to the illegal drug heroin. In nature, opioids are found in the seed pod of the opium poppy plant. Prescription opioids usually come in pill or liquid form, and are given to treat severe pain—for example, pain from dental surgery (read more about drug use and your mouth), serious sports injuries, or cancer. If you are in the hospital, they can be given through an IV (needle and tube) in your arm. Opioids are sometimes prescribed to treat pain that lasts a long time (chronic pain), but it is unclear if they are effective for long term pain.
When opioids are taken as prescribed by a medical professional for a short time, they can be relatively safe and can reduce pain effectively. However, taking prescription opioids, puts you at risk for dependence and addiction. Dependence means you feel withdrawal symptoms when you stop taking the drug. Continued use can lead to addiction, where you continue to seek out the drug and use it despite negative consequences. These risks increase when the medications are misused. Prescription medications are some of the most commonly misused drugs by teens, after tobacco, alcohol, and marijuana.
Opioid medications can be natural, created in labs from natural opioids, or synthetic (human-made). Common opioids and their medical uses are listed below.

Fentanyl has been in the news recently. It is a powerful synthetic (human-made) opioid that is 50 to 100 times stronger than morphine, and is prescribed for extreme pain. It is extremely dangerous if misused, and is sometimes added to illicit drugs sold by drug dealers. Find out more about Fentanyl.
How Prescription Opioids Are Misused
People misuse prescription opioid medications by taking them in a way that is not intended, such as:
- Taking someone else’s prescription, even if it is for a medical reason like relieving pain.
- Taking an opioid medication in a way other than prescribed—for instance, taking more than the prescribed dose or taking it more often, or crushing pills into powder to snort or inject the drug.
- Taking the opioid prescription to get "high."
- Mixing it with alcohol or certain other drugs. Your pharmacist can tell you what other drugs are safe to use with prescription pain relievers.
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.

Short-Term Effects
In addition to pain relief, other effects of opioids include:
- sleepiness
- confusion
- nausea (feeling sick to the stomach)
- constipation
- slowed or stopped breathing
Mixing prescription opioid medications with alcohol can cause a dangerous slowing of the heart rate and breathing. This can lead to a coma or death.
Long-Term Effects
People who use prescription opioid medicines for a long period of time increase their risk of addiction and overdose.
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).

Prescription opioids are closely related to heroin chemically, and their effects can be very similar, especially when misused. Nearly 80 percent of people addicted to heroin started first with prescription opioids. Heroin can be cheaper to get, so about 4% of people who misuse prescription pain medications switch to heroin. This adds up to hundreds of thousands of heroin users, because millions of people are misusing prescription opioids.2

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.

Misuse of prescription opioid medications among teens has declined steadily since 2009. In fact, past-year use of Vicodin® and OxyContin® among 12th graders has dropped dramatically in the last 15 years, from 10.5 percent in 2003 to 1.7 percent in 2018 for Vicodin®, and from 4.5 percent in 2003 to 2.3 percent in 2018 for OxyContin®.
Below is a chart showing the latest percentage of teens who misuse prescription opioid pain medicines. The latest numbers are promising—for example, suggesting that in 2018 more than 97% of 8th, 10th, and 12th graders did not misuse Vicodin.
