Why Do Withdrawal Effects Occur?

Methadone works by mimicking your body’s natural endorphins, the chemicals that reduce the perception of pain.  The longer you take methadone, the less your endorphins your body produces naturally. When you suddenly quit, you will experience intense pain in places that don’t normally hurt.

What Are The Symptoms of Methadone Withdrawal?

Because methadone stays longer in the body system, detox can be a long and painful process. A study from the Journal of Psychoactive Drugs indicates that methadone withdrawal can be more severe than heroin withdrawal. Common withdrawal symptoms include

  • Intense muscle, bone and joint pain
  • Fever, chills and cold sweats
  • Nausea, vomiting, diarrhea and stomach pain
  • Muscle tremors
  • Insomnia
  • Restlessness and agitation
  • Anxiety
  • Depression and thoughts of suicide

How Long Does Methadone Withdrawal Last?

Withdrawal symptoms typically peak in intensity two to four days after the last dose of methadone, although people who take very high doses of methadone typically experience a peak in four to six days. In both groups, symptoms may persist for 10 to 12 days. For chronic users however, symptoms may last up to weeks or even months.

Why Is Professional Detox for Methadone Important?

The intensity of methadone withdrawal symptoms can make it challenging to successfully detox alone. Under the watchful care of competent and caring medical personnel, a professional detoxification program allows for the safest and most efficient detox process possible.

Is Detox Enough?

Many people mistakenly believe that the process of withdrawal is the hardest part of recovery. In reality, the physical effects of methadone addiction are just the symptoms of a deeper and more serious problem. Rehab will help you explore the psychological aspect of your addiction and provide you with the tools for achieving long-term sobriety. Detox is the first step that makes recovery possible, not the end goal.
