What You'll Learn
Methadone withdrawal symptoms
Abruptly discontinuing methadone can lead to severe and distressing withdrawal symptoms, both physical and psychological. The severity of these symptoms can increase the longer a person has been taking methadone, and the higher the dosage.
- Intense cravings for methadone
- Muscle pain and aches
- Abdominal cramps and gastrointestinal discomfort
- Nausea and vomiting
- Diarrhea
- Insomnia or disturbed sleep patterns
- Anxiety, irritability, and mood swings
- Depression and other psychological distress
- Runny nose and watery eyes
- Sweating and chills
- Widened pupils
- Backache and joint pain
- Weakness and fatigue
- Headaches
In rare cases, psychosis has been reported as a symptom of methadone withdrawal. This is when a person experiences hallucinations, delusions, or a loss of contact with reality.
It is important to seek professional assistance when considering discontinuing methadone, as the withdrawal symptoms can be extremely distressing and difficult to manage alone. A supervised medical detox is recommended, as it guarantees a safer and more comfortable withdrawal process under professional supervision.

Methadone overdose
Methadone is a strong painkiller and a long-acting synthetic opiate used for analgesia and opioid addiction detoxification and maintenance. It is typically used to treat moderate to severe pain and opioid addiction. However, it is associated with a risk of overdose, which can have serious and life-threatening consequences.
A methadone overdose occurs when someone accidentally or intentionally takes more than the recommended amount of the drug. This can happen by taking a larger dose than prescribed or by combining methadone with certain painkillers, such as oxycodone, hydrocodone, hydromorphone, or morphine. The risk of overdose is also increased when methadone is misused or abused, particularly by individuals who are not prescribed the medication or are not under medical supervision.
The signs and symptoms of a methadone overdose can vary but typically involve the central nervous system and respiratory function. The classic triad of symptoms includes central nervous system depression, respiratory depression, and myopic pupils. Other symptoms may include coma, seizures, and a decreased level of consciousness. In severe cases, an overdose can lead to permanent complications, such as pneumonia, muscle damage, brain damage, or even death.
If you suspect someone is experiencing a methadone overdose, it is crucial to seek immediate medical assistance. Do not induce vomiting unless instructed by a healthcare professional or poison control centre. Naloxone, a life-saving medication, can be administered to reverse the effects of an opioid overdose, including methadone. It is often available without a prescription, and following its administration, medical attention should still be sought immediately.
To prevent methadone overdose, it is essential to follow the prescribed dosage instructions and not take extra or early doses, even if experiencing pain. Additionally, it is crucial to be honest with your doctor about your methadone use and any other medications you are taking to ensure safe and effective treatment.

Methadone and serotonin syndrome
Methadone is a drug that is used to treat moderate to severe pain and is typically administered when around-the-clock pain relief is required for a long period of time. It is also used to treat opioid use disorder, such as addiction to heroin or other morphine-like drugs. Methadone is an opioid that acts on the central nervous system (CNS) to relieve pain.
Serotonin syndrome is an adverse event triggered by the use of molecules such as selective serotonin reuptake inhibitors and serotonin-norepinephrine reuptake inhibitors. It causes symptoms such as excessive perspiration, clonus, and tremors due to excessive serotonin in the central nervous system. Serotonin syndrome may be provoked by the addition or increase of serotonergic agents, and some narcotics, including methadone, have been associated with the development of serotonin syndrome when used in conjunction with other agents.
In 2016, the United States Food and Drug Administration (FDA) released a Drug Safety Communication to warn the medical community about the risk of serotonin syndrome secondary to opioid use. There have been reported cases of serotonin syndrome developing immediately after the initiation of low-dose methadone therapy, with symptoms including excessive perspiration, chills, and tremors. In one case, a patient experienced alleviation of symptoms upon discontinuation of methadone, with the symptoms disappearing completely within 3 days.
It is important to note that most cases of serotonin toxicity are provoked by therapeutic doses of a combination of two or more serotonergic drugs. Methadone can cause serious unwanted effects if taken by adults who are not used to strong opioid pain medications. Therefore, it is crucial to discuss any concerns with a healthcare provider and follow their guidance regarding dosage and treatment plans.

Methadone and pregnancy
Opioid addiction during pregnancy can be incredibly dangerous, and it is imperative that expectant mothers seek treatment. Methadone is a common medication used to treat opioid addiction and chronic pain management. It is an opioid agonist, meaning it binds to the same receptors as opioids like heroin, but it does not produce the same euphoric effect. This makes it safer for pregnant women with opioid addiction, as it can prevent withdrawal symptoms and reduce the risks associated with opioid use during pregnancy.
However, methadone use during pregnancy is not without risks. A study showed that there is a higher risk of birth defects when methadone is used during the first trimester. Additionally, pharmacokinetic and physiologic changes during pregnancy may require dose adjustments, especially in the third trimester. Untreated opioid addiction during pregnancy can lead to complications such as preterm birth, increased risk of infectious diseases, and neonatal abstinence syndrome (NAS). NAS can cause severe malnutrition and cognitive issues in newborns, and in severe cases, the baby may die before birth.
Methadone maintenance treatment is a time-tested tool with minimal risks compared to opioid use. It is crucial to start with the right dose of methadone to effectively fight addiction, and this should be done under careful medical supervision. Alongside methadone treatment, individual behavioural therapies such as cognitive-behavioural therapy (CBT) and contingency management can be effective in addressing the underlying causes of addiction and providing coping strategies.
While on methadone, it is important to discuss any side effects with a healthcare provider. Some common side effects include anxiety, restlessness, a fast heartbeat, fever, sweating, muscle spasms, twitching, nausea, vomiting, and diarrhea. In rare cases, methadone may cause QT prolongation, a rare heart problem that can lead to irregular heartbeat, fainting, or sudden death. It is important to be transparent with your doctor about your medical history and any medications you are taking to ensure the safe use of methadone.

Methadone and addiction
Methadone is a synthetic opioid used to treat moderate to severe pain. It is also used as a treatment medication for opioid addictions, such as heroin. Methadone acts on the same opioid receptors as morphine and heroin to stabilise patients and minimise withdrawal symptoms.
Methadone is a powerful opioid with potentially addictive qualities. It is a federally designated Schedule II drug, meaning it has a legitimate use but also a high likelihood of its users developing a dependence. This also means that it is illegal to use methadone to get high, and abuse can lead to severe mental impairment and physical dependence. As with any opiate, addiction is a common side effect. An addiction to methadone can develop because the drug eases a user's pain. Over time, a user may need to take more of the drug to feel the same effects, which is called tolerance. The body can become dependent on methadone, and withdrawal symptoms can occur if a user stops taking it suddenly.
Methadone is a heavily regulated drug. Patients who are prescribed methadone in an outpatient setting have to go to a methadone clinic every day to be administered their dose. This is because methadone can cause an overdose when taken in high doses, and it is important for doctors to monitor patients for this. Methadone is the "most effective medication for addiction ever developed", according to LDI Associate Fellow Ashish Thakrar. It reduces mortality, overdoses, illicit opioid use, and the spread of infectious diseases.
To treat opioid addiction, methadone is used alongside medical supervision and counselling. Experts say that people who take methadone to treat an addiction should use it for at least a year while they work on recovery. It is important to be honest with your doctor about your methadone use and how you are feeling during your treatment.
