Synthetic opioids, such as methadone, are made from chemicals without using a naturally occurring opioid as starting material. Prescription opioids come in various forms, including as tablets, capsules, syrups, solutions and suppositories. Opioids are prescribed by licensed medical practitioners to people with acute or chronic pain. Opioids are also prescribed to people with moderate to severe coughs and diarrhea.
The opioids methadone and buprenorphine are prescribed to treat addiction to other opioids. Using prescription opioids for reasons other than their medical purpose is considered abuse. Much attention is given to the abuse of illegal opioid drugs, such as heroin. However, some of the most commonly abused opioids are prescription drugs, such as codeine-containing Tylenol, hydromorphone, oxycodone, morphine and others.
Low doses of opioids suppress the sensation of pain and the emotional response to pain. They may also produce euphoria, drowsiness, relaxation, difficulty concentrating, constricted pupils, a slight decrease in respiratory rate, nausea, vomiting, constipation, loss of appetite and sweating.
With higher doses, these effects are more intense and last longer. The onset and intensity of the effects of opioids vary depending on how the drugs are taken. When taken orally, the effects come on gradually and are usually felt in about 10 to 20 minutes. When injected into a vein, the effects are most intense and are felt within one minute.
When opioids are taken to relieve pain, the duration of the effect varies depending on the type of opioid taken. For many opioids, a single dose can provide pain relief for four to five hours. When opioids are used as directed under medical supervision, there is little risk of addiction.
However, the risk appears to be higher in people with a history of abuse or addiction. Anyone who takes opioids regularly will develop physical dependence. Physical dependence is the result of the body adapting to the presence of the drug, and is not the same as addiction. A person who is physically dependent will experience withdrawal symptoms about six to 12 hours after last taking a short-acting opioid, such as hydromorphone, and about one to three days after last taking a long-acting opioid, such as methadone.
Fentanyl is a powerful synthetic opioid that is similar to morphine but is 50 to times more potent. Like morphine, it is a medicine that is typically used to treat patients with severe pain, especially after surgery. Synthetic opioids, including fentanyl, are now the most common drugs involved in drug overdose deaths in the United States.
In , Opioids are a class of drugs naturally found in the opium poppy plant. Some opioids are made from the plant directly, and others, like fentanyl, are made by scientists in labs using the same chemical structure semi-synthetic or synthetic.
The illegally used fentanyl most often associated with recent overdoses is made in labs. This synthetic fentanyl is sold illegally as a powder, dropped onto blotter paper, put in eye droppers and nasal sprays, or made into pills that look like other prescription opioids.
Some drug dealers are mixing fentanyl with other drugs, such as heroin, cocaine, methamphetamine, and MDMA. This is because it takes very little to produce a high with fentanyl, making it a cheaper option. They might be taking stronger opioids than their bodies are used to and can be more likely to overdose. Like heroin, morphine, and other opioid drugs, fentanyl works by binding to the body's opioid receptors, which are found in areas of the brain that control pain and emotions. When people become addicted, drug seeking and drug use take over their lives.
Yes, a person can overdose on fentanyl. An overdose occurs when a drug produces serious adverse effects and life-threatening symptoms. When people overdose on fentanyl, their breathing can slow or stop. This can decrease the amount of oxygen that reaches the brain, a condition called hypoxia. If you suspect someone has overdosed, the most important step to take is to call so he or she can receive immediate medical attention.
Once medical personnel arrive, they will administer naloxone. Naloxone is a medicine that can treat an opioid overdose when given right away. It works by rapidly binding to opioid receptors and blocking the effects of opioid drugs. Some states have passed laws that allow pharmacists to dispense naloxone without a personal prescription.
Friends, family, and others in the community can use the nasal spray versions of naloxone to save someone who is overdosing. Yes, repeated misuse of prescription opioids can lead to a substance use disorder SUD , a medical illness which ranges from mild to severe and from temporary to chronic.
Addiction is the most severe form of an SUD. An SUD develops when continued misuse of the drug changes the brain and causes health problems and failure to meet responsibilities at work, school, or home. People addicted to an opioid medication who stop using the drug can have severe withdrawal symptoms that begin as early as a few hours after the drug was last taken. These symptoms include:. These symptoms can be extremely uncomfortable and are the reason many people find it so difficult to stop using opioids.
There are medicines being developed to help with the withdrawal process, including lofexidine , a non-opioid medicine designed to reduce opioid withdrawal symptoms that was approved by the U.
A range of treatments including medicines and behavioral therapies are effective in helping people with opioid addiction. Two medicines, buprenorphine and methadone, work by binding to the same opioid receptors in the brain as the opioid medicines, reducing cravings and withdrawal symptoms. Another medicine, naltrexone, blocks opioid receptors and prevents opioid drugs from having an effect. Behavioral therapies for addiction to prescription opioids help people modify their attitudes and behaviors related to drug use, increase healthy life skills, and persist with other forms of treatment, such as medication.
Some examples include, cognitive behavioral therapy which helps modify the patient's drug use expectations and behaviors, and also effectively manage triggers and stress.
Multidimensional family therapy, developed for adolescents with drug use problems, addresses a range of personal and family influences on one's drug use patterns and is designed to improve overall functioning.
These behavioral treatment approaches have proven effective, especially when used along with medicines. This publication is available for your use and may be reproduced in its entirety without permission from NIDA.
