Methadone is NOT Used in Abortion Procedures

Methadone is a medication for treating opioid use disorder (OUD) and has no role whatsoever in abortion procedures. The confusion likely stems from the similar-sounding name "methadione" in your question, but methadone is an opioid agonist used exclusively for addiction treatment and pain management, not for pregnancy termination.

What Methadone Actually Does

Methadone is a full mu-opioid receptor agonist used specifically for:

  • Treatment of opioid use disorder in pregnancy - It is the standard of care alongside buprenorphine for pregnant persons with OUD 1
  • Maintenance therapy - Must be administered daily at federally accredited opioid treatment programs under direct observation 1
  • Chronic pain management - Continued perioperatively in patients on chronic opioid therapy 2

Medications Actually Used in Abortion

The evidence-based medications for medical abortion are completely different 3:

  • Mifepristone - An antiprogestin that blocks progesterone receptors
  • Misoprostol - A prostaglandin that causes uterine contractions
  • Methotrexate - An antimetabolite (less commonly used)

Pain Management During Abortion

When opioids are studied for abortion-related pain, the research shows they are largely ineffective:

  • Hydrocodone-acetaminophen does not decrease pain during first-trimester surgical abortion and may increase postoperative nausea 4
  • Oxycodone does not reduce maximum pain experienced during medical abortion up to 10 weeks gestation 5
  • Standard pain management relies on NSAIDs (ibuprofen 800mg) rather than opioids 4, 5

Critical Distinction: Methadone in Pregnancy

If a pregnant person with OUD is considering abortion, methadone therapy should be continued throughout any procedure:

  • Women should remain on their daily maintenance dose during labor, delivery, or any surgical procedure to prevent acute withdrawal 1
  • Methadone continuation is associated with reduced pregnancy complications, higher birth weights, and improved prenatal care adherence when pregnancy is continued 1
  • Perioperative guidelines recommend continuing methadone on the morning of surgery and the night before to avoid withdrawal 2

The bottom line: Methadone treats addiction, not pregnancy. It plays no role in abortion procedures themselves.
