Opioids and Opioid Use Disorder (OUD)

What are opioids?

From: MedlinePlus, National Library of Medicine

Opioids, sometimes called narcotics, are a type of drug. They include strong prescription pain relievers such as oxycodone, hydrocodone, fentanyl, and tramadol. The illegal drug heroin is also an opioid. Some opioids are made from the opium plant, and others are synthetic (man-made).

A health care provider may give you a prescription opioid to reduce pain after you have had a major injury or surgery. You may get them if you have severe pain from health conditions like cancer. Some providers prescribe them for chronic pain.

What are the side effects and risks of opioids?

From: MedlinePlus, National Library of Medicine

Opioids can cause side effects such as drowsiness, mental fog, nausea, and constipation. They may also cause slowed breathing, which can lead to overdose deaths. If someone has signs of an overdose, call the local emergency number (112 in India). These signs may include:

• Very small pupils of the eyes
• Falling asleep or loss of consciousness
• Slow, shallow breathing
• Choking or gurgling sounds
• Vomiting
• Limp body
• Pale, blue, or cold skin
• Faint heartbeat
• Purple lips and fingernails

When using opioids, there is also a risk of opioid use disorder (OUD).

What is opioid use disorder (OUD)?

From: MedlinePlus, National Library of Medicine

Opioid use disorder (OUD) means that you have a problematic pattern of using opioids. The pattern causes a lot of distress and impairment (meaning that it causes problems in and interferes with your daily life). Instead of OUD, sometimes people use the terms "opioid dependence" and "opioid addiction." Dependence means feeling withdrawal symptoms when not taking the drug. Addiction is a chronic brain disease that causes a person to compulsively seek out drugs, even though they cause harm.

The risk of OUD is higher if you misuse the medicines. Misuse can include taking more than your prescribed dose or taking it more often, using it to get high, or taking someone else's opioids.

Opioid use disorder and overdoses are serious public health problems in the United States. As more people misuse opioids, more women are misusing opioids during pregnancy. This can lead to health risks for the mother and baby. The baby may be born with neonatal abstinence syndrome (NAS). NAS is a group of withdrawal symptoms that a baby has after being exposed to drugs during pregnancy.

Another problem with increased opioid misuse is that it can also lead to more heroin use. There are some people who switch from prescription opioids to heroin because heroin may be cheaper and easier to get.

How are opioid use disorder (OUD) and opioid overdose treated?

From: MedlinePlus, National Library of Medicine

There are effective medicines to treat OUD. Using medicines to treat OUD is called medications for opioid use disorder (MOUD). MOUD can help you stop using the drug, get through withdrawal, and cope with cravings. It is often combined with behavioral therapy and counseling. Having support from family and friends can also help.

There is also a medicine called naloxone which can treat opioid overdoses. It can reverse the effects of the overdose and prevent death if it is given quickly.

How can I prevent problems when taking prescription opioids?

From: MedlinePlus, National Library of Medicine

To prevent problems with prescription opioids, be sure to follow your doctor's instructions when taking them. Do not share your medicines with anyone else. Contact your doctor if you have any concerns about taking the medicines.

Which doctor should you see?

The suggested department for discussing Opioids and Opioid Use Disorder (OUD) is Psychiatry, with a psychiatrist as the relevant type of clinician. General physician / Family Medicine; paediatrician for children. Referral depends on symptoms.

This is an editorial referral starting point. The appropriate clinic depends on the person’s age, symptoms, previous diagnosis and local services. The first clinician can decide whether another specialty or a team is needed; a department label does not confirm the diagnosis.

How to prepare for an assessment

Bring a short timeline of the main symptoms: when they first appeared, whether they are constant or episodic, what seems to change them, and how they affect daily activities. Include previous reports, discharge summaries, current medicines and supplements, allergies, and any relevant family history. A dated record is more useful than trying to match every feature in an online article.

Ask the clinician what is already established and what remains uncertain. If a test is suggested, ask what question it answers, what its limitations are and how the result would change the next step. The information here is not an instruction to arrange every possible test. In children, bring growth, developmental and school information if it is relevant to the concern.

• How are symptoms affecting safety, sleep, relationships and everyday function?
• What roles could psychological treatment, medicines or support services have?
• Who should be contacted if safety or functioning deteriorates?

Treatment discussions and follow-up

Where the source describes treatments, these are an overview of possible care, not a prescription for an individual. Ask which option applies to the confirmed diagnosis, what benefit is expected, what adverse effects to watch for and how progress will be assessed. Availability, approvals and local practice can differ from the country described in the source.

Before leaving the appointment, clarify the next review date, who will communicate results, and whom to contact if the situation changes. Discuss difficulties with sleep, work, school, mobility, eating or emotional wellbeing when these are relevant. Practical support may require coordination between the treating clinician and other services.

The collected references do not establish a complete prevention or long-term outlook section for this entry. Missing information should not be interpreted as proof that prevention is impossible or that a particular outcome is inevitable. Ask what is known for the exact subtype, stage and personal circumstances, and which uncertainties remain.

When to seek emergency help

Severe breathing difficulty, collapse, new stroke-like symptoms, a seizure that is prolonged or repeated without recovery, uncontrolled major bleeding, or an immediate risk of self-harm require emergency help. In India, call 112 or reach the nearest emergency department. This is a general, non-exhaustive warning list; it is not a condition-specific triage tool.
