Also known as: Oxy, Percs, Happy Pills, Hillbilly Heroin, OC, or Vikes
Prescription opioids are medications that are chemically similar to endorphins – opioids that our body makes naturally to relieve pain – and also similar to the illegal drug heroin. In nature, opioids are found in the seed pod of the opium poppy plant. Opioid medications can be natural (made from the plant), semi-synthetic (modified in a lab from the plant), and fully synthetic (completely made by people).
Prescription opioids usually come in pill form and are given to treat severe pain—for example, pain from dental surgery, serious sports injuries, or cancer. Opioids are also commonly prescribed to treat other kinds of pain that lasts a long time (chronic pain), but it is unclear if they are effective for long term pain.
For most people, when opioids are taken as prescribed by a medical professional for a short time, they are relatively safe and can reduce pain effectively. However, dependence and addiction are still potential risks when taking prescription opioids. Dependence means you feel withdrawal symptoms when not taking the drug. Continued use can can lead to addiction, where you continue to use despite negative consequences. These risks increase when these medications are misused. Prescription medications are some of the most commonly misused drugs by teens, after tobacco, alcohol, and marijuana.
Common opioids and their medical uses are listed below.

Fentanyl has been in the news recently. It is a powerful opioid prescribed for extreme pain that is 50 to 100 times more potent than morphine. It is extremely dangerous if misused, and is sometimes added to illicit drugs sold by drug dealers. Find out more about Fentanyl.
Types of opioids:
Type of Opioid
How Are They Derived
Natural opioids (sometimes called opiates)
nitrogen-containing base chemical compounds, called alkaloids, that occur in plants such as the opium poppy
morphine, codeine, thebaine
created in labs from natural opioids
hydromorphone, hydrocodone, and oxycodone (the prescription drug OxyContin), heroin (which is made from morphine)
Fully synthetic/man-made opioids
fentanyl, pethidine, levorphanol, methadone, tramadol, dextropropoxyphene
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 legitimate medical purpose like relieving pain.
- Taking an opioid medication in a way other than prescribed—for instance, taking more than your 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 them with alcohol or certain other drugs. Your pharmacist can tell you what other drugs are safe to use with prescription pain relievers.
Opioids attach to specific proteins, called opioid receptors, on nerve cells in the brain, spinal cord, gut, and other organs. When these drugs attach to their receptors, they block pain messages sent from the body through the spinal cord to the brain. They can also reduce or stop other essential functions like breathing.
Opioid receptors are also located in the brain’s reward center, where they cause a large release of the neurotransmitter dopamine. This causes a strong feeling of relaxation and euphoria (extreme good feelings). Repeated surges of dopamine in the reward center from drug-taking can lead to addiction.

In addition to pain relief and euphoria, other effects of opioids include:
- nausea (feeling sick to the stomach)
- slowed or stopped breathing
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. Nearly 23,000 people died from an overdose of a prescription pain medication in 2015, with alarming increases among young people ages 15 to 24.1 Learn more about drug overdoses in youth.
The risk of overdose and death increase if you combine opioids with alcohol or other medications that also slow breathing, such as Benzodiazepines (e.g. Xanax).
Signs of Overdose
Signs of a possible prescription opioid overdose are:
- slow breathing
- blue lips and fingernails
- cold damp skin
- vomiting or gurgling noise
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 or autoinjector. 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 chemically closely related to heroin, and their effects, especially when misused, can be very similar. Because heroin may be cheaper to get, people who have become addicted to prescription pain medications sometimes switch to using heroin. Nearly 80 percent of people addicted to heroin started first with prescription opioids. However, the transition to heroin use from prescription opioids is still rare; only about 4 percent of people who misuse prescription opioids use heroin. Even so, because millions of people are using prescription opioids, this adds up to hundreds of thousands of heroin users.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.
Opioid withdrawal can cause:
- muscle and bone pain
- sleep problems
- vomiting (throwing up)
- cold flashes with goosebumps (“cold turkey”)
- involuntary leg movements
Carefully following the doctor’s instructions for taking a medication can make it less likely that someone will develop dependence or addiction, because the medication is prescribed in amounts and forms that are considered appropriate for that person.
Doctors should always weigh the risks of opioid dependence and addiction against the benefits of the medication, and 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.
