Meperidine Addiction Risk
Meperidine, the generic form of Demerol, is a synthetic opioid drug used to treat severe acute pain. Meperidine works by binding to opioid receptors located through a person’s brain, body and spinal cord. This can change how pain signals are sent from the body to the brain, which is why opioids are such powerful pain relievers. When opioids bind to receptor sites, however, they can also create pleasurable or euphoric effects because an artificially high amount of dopamine is released into the brain and body. This can create a reward and reinforcement response, which can then lead to addiction.
When someone takes meperidine as prescribed and only for a short time, the risk of addiction is somewhat low. However, opioid misuse can increase the likelihood of an addiction forming and cause other dangerous side effects. Meperidine also has a black box warning that states the drug may be habit-forming, especially with long-term use. This risk can be especially high in people with a personal or family history of excessive drug or alcohol use.
Meperidine addiction can be both psychological and physical in nature. Additionally, if someone takes meperidine for more than a few weeks, they may experience withdrawal symptoms if they suddenly stop using it.
Symptoms of Meperidine Abuse
Meperidine is a controlled substance in the U.S. As a result, misusing it not only increases the risk of negative side effects — it can also be illegal.
Symptoms of meperidine misuse occur when you take doses more frequently or in higher amounts than prescribed. There are various signs that point towards the possibility of meperidine abuse, including long pauses between breaths, slowed breathing and abnormally constricted pupils. Other symptoms include:
- Constant itching
- Changes in mood or behavior
- Drug-seeking behaviors
- Anxiety or depression
- Developing a tolerance
- Keeping stashes of meperidine
- Irritability or agitation
- Lying about how much meperidine is being used
Meperidine Long-Term Effects
Over time, meperidine use can lead to serious side effects. When the brain is repeatedly exposed to an opioid like meperidine, the drug changes the brain’s structure, wiring and function. People who have been taking opioids for a long time can have imbalances in their neurons and hormones. Some studies have also shown a decline in the brain’s white matter due to long-term opioid use. This can lead to problems with thinking, behavior and decision-making.
Damage to organs and systems throughout the body can start to occur, especially when they don’t receive the oxygen they need due to slowdowns in the central nervous system. Complications from chronic constipation can occur, and the longer someone uses meperidine, the more likely they are to develop a physical dependence.
What Are Common Meperidine Withdrawal Symptoms?
Opioids can also lead to the formation of dependence. Due to how opioids interact with the brain and certain chemicals, a person may become dependent on the drug’s effects. This is because the brain alters its own functionality in response to the effects of the opioid drug.
If someone is dependent on meperidine and stops using it suddenly, they’re likely to experience withdrawal symptoms. Withdrawal symptoms can occur even if someone is using this medication exactly as prescribed.
Common meperidine withdrawal symptoms can include:
- Nausea and vomiting
- Runny nose
- Aches and pains
- Flu-like symptoms
- Changes in blood pressure
- Strong drug cravings
Meperidine Withdrawal Timeline and Symptom Duration
Opioid withdrawal isn’t typically deadly, but it is uncomfortable and can be difficult to manage. The meperidine withdrawal timeline can vary depending on certain factors, including:
- Length of drug use
- The dosages that were regularly used
- Use of other substances
Generally, symptoms will start anywhere from 12 hours to two days after the last meperidine dose. During the first one to two days after stopping meperidine, a person may experience nausea, vomiting, restlessness and some tremors. Withdrawal symptoms will usually continue during days three to four and then peak within the first week. For most people, symptoms will subside after one to two weeks. However, some people may experience ongoing symptoms, particularly psychological symptoms like anxiety and depression.
Managing Symptoms of Meperidine Withdrawal
Before stopping meperidine, it’s important to seek guidance from a medical professional to make the withdrawal process more comfortable and reduce the risk of complications. To help ease withdrawal symptoms, most physicians will recommend that patients gradually taper down their drug dosage instead of stopping suddenly, which is known as going “cold turkey.” It’s important not to taper a dose without medical guidance, as doing so can lead to severe symptoms.
Certain prescription or over-the-counter medications may be taken to help relieve withdrawal symptoms. For people who have been taking opioids for a long time or who are more likely to have severe withdrawal symptoms, a medically supervised detox may be the best option. A medically supervised detox provides around-the-clock care and supervision. This kind of setting increases a person’s chances of successfully detoxing from meperidine, allowing them to begin addiction treatment afterward.
With some drugs, there are FDA-approved medications that can be provided during detox. Opioid withdrawal drugs include methadone, buprenorphine and naltrexone. Methadone and buprenorphine can help reduce withdrawal symptoms and cravings because they act as milder opioids. However, there is still some risk of addiction and dependence with these drugs. Naltrexone is an opiate antagonist, meaning it blocks the effects of opioids and can reduce cravings. Along with FDA-approved opioid withdrawal drugs, other medicines may be given as needed. Clonidine is a drug often used to ease a variety of withdrawal symptoms during detox, and others are available as well.
Treatment Options for Meperidine Addiction Symptoms
Certain symptoms can be used to diagnose addiction, and addictions can be characterized as mild, moderate or severe. If someone is addicted to meperidine, they will likely require professional treatment.
Treatment options can vary based on the type of program, how long it lasts and the specific therapies and approaches used. The ultimate goal of any meperidine addiction treatment program is to help people stop using drugs and productively return to their daily lives. General addiction treatment options include medical detox followed by inpatient or outpatient treatment.
Choosing a Meperidine Rehab Center
When choosing a meperidine rehab center, everyone is going to have their own preferences and priorities. Some things to think about that can guide the decision include:
- Does the program have a medical detox?
- How severe is the addiction? Did it just begin or is it a long-term, ongoing addiction?
- Has the person tried other types of treatment previously?
- Can the person take time away from school or work to attend treatment?
- How comfortable is the person with leaving their home and potentially their state?
- Would a supportive, supervised environment work well for the person?
- What kind of support system does the person have at home?
- Is dual diagnosis treatment available for mental health disorders that occur alongside the addiction?

FAQs About Meperidine
Meperidine is a generic opioid drug, most commonly known by the brand name Demerol. It is a synthetic opioid that is similar to morphine, and it was first synthesized in the late 1930s. Meperidine is used for the treatment of moderate-to-severe pain, and it’s sometimes used to put people to sleep before a procedure or for pain relief following childbirth. As an opioid analgesic, meperidine binds to certain opioid receptor sites throughout the body of the patient. This changes how the brain and the nervous system send pain signals and respond to pain. Meperidine is available as a tablet and a syrup, and it’s taken as needed. Some of the side effects of meperidine can include nausea, vomiting, constipation, dry mouth, sweating and changes in vision. Severe side effects may occur as well, including slow or labored breathing.
Meperidine is the active ingredient in the brand-name drug Demerol, which is frequently given in tablet form. A Demerol tablet is usually small, white and scored. Depending on the dosage and the manufacturer, it may have different markings and logo imprints. It’s usually given as either a 50 mg or 100 mg dosage. There are also meperidine injection solutions available in dosages of 25 mg, 50 mg, 75 mg and 100 mg per mL of solution. A meperidine syrup is available as well, which can be taken orally.
Mixing alcohol with meperidine or any other opioid can be dangerous because alcohol changes how the body metabolizes substances. Taking alcohol and meperidine together can cause higher concentrations of the drug in the body of the patient. The side effects can range from uncomfortable symptoms, such as nausea or vomiting, to life-threatening symptoms, such as respiratory depression. The severe risks of mixing alcohol and meperidine are even greater if someone is misusing the drug by taking large doses or by crushing it to snort or inject it. If someone is regularly mixing alcohol and meperidine, they may have a polysubstance addiction. Simultaneous addictions aren’t uncommon, but they require specialized detox and in-depth addiction treatment.
