Methadone Treatment: Uses, Benefits, and What to Expect

Disclaimer: This article is for educational purposes only and does not replace expert medical or mental health advice. Opioid use disorder or severe/chronic pain requires a comprehensive psychiatric and physical evaluation by a qualified clinician. So, always refer to a licensed mental health specialist for diagnosis and treatment.

Methadone is a U.S. Food and Drug Administration (FDA)-approved opioid medication used to treat opioid use disorder. It is also used to treat severe and chronic pain. It is classified as a Schedule II substance under the Controlled Substances Act in the U.S., so it is only available under a doctor’s prescription and must be taken under medical supervision.

Methadone is a synthetic opioid agonist. The National Institute on Drug Abuse (NIDA) notes that it has been used for over 50 years now to treat opioid use disorder.

Methadone binds to mu-opioid receptors, similar to other powerful opioids, like morphine, heroin, or even fentanyl. However, the difference here is that methadone slowly activates the mu-opioid receptors and produces a reduced sense of euphoria, which serves to control cravings and opioid withdrawal symptoms.

Methadone comes as a liquid, powder, and tablet. It is only provided under a doctor’s prescription. If prescribed for pain, then the dosage and frequency will be as per the doctor’s instructions.

If it is prescribed for opioid use disorder, then it is prescribed as per the standards cited in 42 Code of Federal Regulations (CFR). It will be integral to medication-assisted treatment (MAT), which also combines behavioral therapies and counseling for a lasting recovery.

Your doctor may begin with a lower dosage of 20 mg per day with a maximum dosage of 40 mg per day, initially. However, it must be noted dosage and frequency of methadone will vary as per the unique needs and circumstances of each person. As it comes with both benefits and side effects, close medical supervision and medication management become very integral to methadone use in opioid use disorder.

Methadone leaves the body far more slowly than its effects wear off. Its effect on pain and cravings can fade within hours, while the drug itself stays in the body for a day or longer and builds up over the first several days of treatment. This is why the starting dose is kept low and raised slowly under medical supervision.

The main danger is taking an extra dose because the effect seems to have faded while the level in the body is still rising. Fatalities during methadone treatment are most likely to occur during this induction period, especially the first two weeks.

In the first weeks, never take extra doses or take doses closer together, even if the medication feels like it is not working. Call your doctor or clinic instead.

The benefits of methadone are as follows:

• Reduces or stops opioid misuse
• Reduces the risk of opioid-related overdose deaths
• Reduces the risk of relapse
• Reduces the risk of infections
• Reduces the risk of illegal behaviors
• Helps manage severe or chronic pain where other opioid medications have failed.

The Substance Abuse and Mental Health Services Administration (SAMHSA) cautions regarding the following side effects of methadone:

• Restlessness
• Itchy Skin
• Sweating
• Vomiting
• Constipation
• Sexual problems
• Slowed breathing
• Feeling faint
• Hives or rash
• Chest pain
• Racing heartbeat
• Psychosis.

If you or someone you know is experiencing these side effects, call your doctor immediately.

SAMHSA advises the following precautions you need to take if you have been prescribed methadone:

• Only use methadone as prescribed by your doctor. If you miss a dose, do not take an additional dose on your own. Contact your doctor. If you feel it is not effective, do not stop the medication. Contact your doctor.
• Do not use methadone with alcohol or other drugs, as it can increase the risk and severity of side effects.
• Methadone may lead to slowed reaction times and lightheadedness, so do not drive or operate heavy machinery.
• Store methadone securely and keep it out of the reach of children.
• Dispose of unused or expired methadone safely.
• Methadone can prolong the QT (QTc) interval - a heart rhythm change that can lead to dangerous irregular heartbeats. Your clinician may take an ECG before or during treatment. Tell them about every medication and supplement you take, since many drugs interact with methadone or add to QT risk. Fainting, dizziness, or a racing or irregular heartbeat needs prompt medical attention.
• If you are pregnant or breastfeeding, be open with your doctor about this, as methadone can lead to neonatal abstinence syndrome (NAS) among children, which is when children experience withdrawal symptoms after birth.

Methadone Overdose and Naloxone

Signs of overdose include extreme sleepiness or being unable to wake the person, slow or shallow breathing or no breathing, blue or gray lips or fingertips, pinpoint pupils, a limp body, and gurgling sounds. Call 9-1-1 immediately.

If naloxone (Narcan) is available, give it. Because methadone lasts so long, overdose signs can appear hours after a dose and can return after naloxone wears off, so the person still needs emergency care even if they wake up, and may need more than one dose. Ask your doctor/prescriber or pharmacist about a naloxone prescription, keep it where you can reach it, and make sure the people you live with know how to use it.
