Effects of Methadone Use

Although Methadone is used to aid in the recovery from opioid addiction, the drug can still be abused and cause a variety of debilitating side effects, including: respiratory depression, insomnia, and depression.

Understanding Methadone Use and Its Effects

Each year, hundreds of thousands of people take Methadone to aid in the recovery from Opioid addiction. Methadone is an Opiate agonist that is used in medication-assisted treatment (MAT) to help people reduce or quit their use of Heroin or other Opioids. Methadone is a Schedule II narcotic and works by changing how the brain and nervous system respond to pain. The intended effects of Methadone are to lessen the painful symptoms of Opioid withdrawal and block the euphoric effects of Opioid drugs such as Heroin and Morphine, as well as semi-synthetic Opioids like Hydrocodone. Methadone is available as either a pill, liquid, or wafer form that is taken once daily. Pain relief from a dose of Methadone typically lasts anywhere from four to eight hours.

Like other Opioids, Methadone binds to opioid receptors in the brain and activates them, leading to pain relief. However, unlike other Opioids, Methadone’s effects are much more gradual and milder. The drug absorbs into the body slowly, offering pain relief while preventing the euphoric high that’s experienced with other Opioids. While Methadone is effective at managing cravings for Opioid drugs and reducing withdrawal symptoms, it can still be abused and cause dependence in consumers when misused. As a result, patients who are prescribed Methadone for MAT are often strictly supervised and required to visit a clinic daily to get their dose of the medication.

What Are the Effects of Methadone Use?

As with most medications, there are many benefits to using Methadone, particularly for those in recovery for Opioid addiction. However, there is also a variety of potentially harmful effects that comes with the drug as well. Even if someone only uses Methadone briefly, they may notice some unpleasant physical side effects, such as:

  • Sedation
  • Dry mouth
  • Vision problems
  • Drowsiness
  • Shallow breathing
  • Tremor
  • Lightheadedness
  • Headache
  • Nausea
  • Trouble sleeping
  • Dizziness
  • Loss of appetite
  • Restlessness
  • Decreased heart rate

In addition to these physical side effects, Methadone can also induce some troubling psychological effects, including:

  • Confusion
  • Hallucinations
  • Insomnia
  • Mood swings
  • Decreased sex drive
  • Anxiety
  • Depression
  • Paranoia
  • Delusions
  • Suicidal ideations

In instances that the side effects are too debilitating, the dosage of Methadone will be lowered, or the person may be switched to a different medication, such as Buprenorphine. If someone is abusing Methadone, these symptoms will often worsen and can lead to overdose, resulting in a coma or possibly even death.

Symptoms of a Methadone Overdose

Methadone Use Causes Many Short and Long-Term EffectsA Methadone overdose often occurs because the drug remains in the body for an incredibly long period of time. Methadone has a long half-life and stays in bodily systems much longer than other Opioids. The rate at which the drug is released from the liver and other tissues into the bloodstream is extremely slow, and this can result in a buildup of toxicity in the blood. If toxic levels are reached, both respiratory depression and central nervous system (CNS) depression can occur due to low levels of oxygen in the brain. Even after several hours have passed and the pain relief from the drug has subsided, Methadone is not clear from the body.

Symptoms of overdose may develop slowly so it’s important to know what to look for. Side effects should be taken seriously, as some may indicate an emergency. Patients should stop taking Methadone and contact emergency services right away if any of the following occur:

  • Extreme chest pain or tightness
  • Difficulty breathing
  • Low blood pressure
  • Swelling of the face, lips, tongue, or throat
  • Seizures
  • Unconsciousness
  • Fast or pounding heartbeat
  • Hallucinations
  • Cold or clammy skin
  • Constricted or pinpoint pupils

A Methadone overdose can also occur if a person combines the drug with other CNS depressants and painkillers. Unlike most other Opioid-related deaths, two-thirds of all Methadone deaths involve the use of multiple drugs, such as Oxycodone and alcohol.

The Long-Term Consequences of Methadone Use

Despite the fact that Methadone is relatively milder Opioid drug, it’s important to realize that it is still a narcotic with a high risk of abuse and addiction. When a person takes Methadone in any form, they run the risk of developing a physical dependence on the drug. Methadone addiction can develop through both illicit use, which is any use without a prescription, and intentional misuse of the drug, (i.e., taking more than is prescribed or combining the drug with other substances of abuse). An addiction to any substance can have incredibly dangerous effects on a person, and an addiction to Methadone is no different. Long-term use of the drug can cause irreversible damage to a person’s nerves, liver, and even brain.

The long-term consequences of Methadone use are much like those of other Opioids, including:

  • Cardiovascular issues such as collapsed veins
  • Menstrual cycle changes in women and sexual dysfunction in men
  • Impaired memory and cognitive function
  • Respiratory issues like reduced breathing rates
  • Re-occurring insomnia and hypersomnia
  • Issues with judgment and a tendency to engage in risky behaviors
