Introduction
The escalating opioid crisis in the US has profoundly impacted all demographics, and pregnant women are particularly vulnerable. Substance use disorders during pregnancy are a critical concern, demanding a comprehensive and proactive approach from healthcare providers. It’s no longer sufficient to screen only women who fit stereotypical profiles or seem like “cars medication tools” cases of substance abuse. Universal screening is paramount. This article emphasizes the crucial need for routine substance use screening as part of standard obstetric care, highlighting why overlooking any woman – even those seemingly not “in testing for cars medication tools” – can lead to missed opportunities for intervention and improved maternal and infant health outcomes. Early identification through universal screening, followed by brief intervention and appropriate referral, is not just best practice; it is ethically imperative to ensure all pregnant women receive the care they and their infants deserve.
The Opioid Epidemic and Pregnancy: A Growing Crisis
Opioid use during pregnancy has mirrored the broader epidemic affecting the general population, reaching alarming rates in recent years. Prescription opioid misuse and heroin use have both seen dramatic increases. In 2012, an astounding number of opioid prescriptions were written, double the amount from 1998. Concurrently, admissions to substance use disorder treatment programs for prescription opioid misuse quadrupled between 2002 and 2012, and opioid-related deaths soared nearly 400% from 2000 to 2014. Heroin overdose deaths also surged, increasing over 300% in just five years.
Data reveals the significant impact on pregnant women specifically. In 2007, nearly a quarter of women in Medicaid programs across 46 states filled an opioid prescription during pregnancy. Hospital discharge data further confirms this trend, with antepartum maternal opioid use increasing almost fivefold between 2000 and 2009. This rise in opioid use during pregnancy has directly contributed to a dramatic increase in neonatal abstinence syndrome (NAS), from 1.5 cases per 1,000 hospital births in 1999 to 6.0 per 1,000 in 2013, resulting in billions of dollars in annual hospital charges. Tragically, maternal mortality reviews have also identified substance use as a major factor in pregnancy-associated deaths, underscoring the severity of this public health crisis.

Understanding Opioid Use Disorder
Opioid use disorder is defined as a pattern of opioid use characterized by compulsive drug-seeking behavior despite harmful consequences. It’s a chronic, treatable medical condition that can be effectively managed through a combination of medication, behavioral therapy, and ongoing recovery support. Short-term abstinence-focused programs often lead to relapse, highlighting the need for sustained, comprehensive care.
Diagnosis of opioid use disorder relies on specific criteria outlined in the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5). These criteria include unsuccessful attempts to control opioid use, social problems arising from use, and failure to meet obligations at work, school, or home. The DSM-5 uses a severity scale based on the number of symptoms experienced within a 12-month period: mild (two to three symptoms), moderate (four to five symptoms), and severe (six or more symptoms). While diagnostic terminology has evolved, older terms like “opioid abuse” and “opioid dependence” are still encountered in research and regulatory contexts.
The Crucial Role of Obstetric Care Providers
Pregnant women who use opioids represent a heterogeneous group, and it’s vital for healthcare providers to distinguish between opioid use in the context of medical treatment (for pain or addiction), opioid misuse, and untreated opioid use disorder. All healthcare providers, especially obstetrician-gynecologists and other obstetric care providers, must actively participate in combating the opioid epidemic. Responsible opioid prescribing is essential. Before initiating opioid prescriptions, providers should:
- Ensure appropriate indication: For women with opioid use disorder, opioid agonist pharmacotherapy is the recommended treatment. For chronic pain, prioritize non-opioid and nonpharmacologic approaches.
- Discuss risks and benefits: Clearly communicate the potential for physiological dependence and the risk of neonatal abstinence syndrome (NAS). However, fear of NAS alone should not prevent necessary opioid prescriptions for pregnant women.
- Obtain a thorough substance use history and utilize Prescription Drug Monitoring Programs (PDMPs): PDMPs are valuable tools to identify prior opioid prescriptions and potential misuse, guiding safer prescribing and identifying individuals who would benefit from treatment.
- Discuss family planning: Before initiating long-term opioid therapy in women of reproductive age, discuss family planning and the potential impact of opioid use on future pregnancies.
- Balance pain management with caution: Pregnancy should not be a barrier to treating acute pain. Concerns about opioid misuse or NAS should not prevent necessary pain relief during pregnancy.
Obstetric care providers must be knowledgeable about the medical, social, and legal ramifications of opioid use during pregnancy. Pregnancy offers a critical window to identify and treat women with substance use disorders. Utilizing validated screening tools, offering brief interventions (Screening, Brief Intervention, and Referral to Treatment – SBIRT), and providing referrals for specialized care are fundamental aspects of care. Advocating for this vulnerable population, improving treatment accessibility, and opposing the criminalization of pregnant women with opioid use disorder seeking prenatal care are also essential responsibilities. Furthermore, obstetric care providers have an ethical duty to discourage the separation of families solely based on suspected or confirmed substance use disorder. Punitive legislation should be retracted in favor of evidence-based strategies within the healthcare system to address the needs of women with addictions.

The Physiology and Pharmacology of Opioid Use
Opioids work by reducing the intensity of pain signals and are commonly prescribed for pain management, as well as for cough and diarrhea. They also induce euphoria, which contributes to their misuse potential. Opioid use disorder can develop with repeated use of any opioid, particularly in individuals with genetic predispositions. Heroin, a fast-acting opioid, can be injected, smoked, or snorted and requires frequent dosing due to its short half-life to prevent withdrawal. Prescription opioids such as codeine, fentanyl, morphine, methadone, oxycodone, and buprenorphine also carry misuse potential and can be taken through various routes of administration. All opioids pose a risk of respiratory depression, overdose, and death, with full agonists like fentanyl carrying a higher risk than partial agonists like buprenorphine. Injection drug use further increases risks of infections like cellulitis, hepatitis, and HIV.
Regular, long-term opioid use leads to physiological dependence and withdrawal symptoms upon cessation. Opioid withdrawal symptoms include pain, nausea, sweating, and anxiety. Withdrawal onset and duration vary depending on the opioid’s half-life, with short-acting opioids causing withdrawal within hours, peaking in days, and lasting about a week, while long-acting opioids’ withdrawal starts later and lasts longer. Unlike alcohol withdrawal, opioid withdrawal is rarely life-threatening and is manageable.
Effects of Opioid Use on Pregnancy and Pregnancy Outcomes
Observational studies have examined the safety of opioids in early pregnancy. Early reports found no increased risk of birth defects with prenatal exposure to oxycodone, propoxyphene, or meperidine. Some studies suggested a link between first-trimester codeine use and congenital abnormalities, while others did not. One study noted increased risk of certain birth defects with prescribed opioid use around conception and in the first trimester. Another study indicated a possible association between first-trimester opioid use and neural tube defects, but methodological limitations exist in these studies. A meta-analysis comparing methadone and buprenorphine found no difference in congenital malformations and reported anomaly rates similar to the general population. Overall, the small potential increased risk of birth defects associated with opioid agonist pharmacotherapy must be weighed against the significant risks of ongoing opioid misuse during pregnancy.
Untreated heroin addiction during pregnancy is linked to poor prenatal care, fetal growth restriction, placental abruption, fetal death, preterm labor, and meconium aspiration. Untreated addiction also correlates with high-risk behaviors like prostitution and criminal activity, increasing the risks of STIs, violence, legal issues, and loss of child custody.
Pregnant women with opioid use disorder frequently experience co-occurring mental health conditions like depression, trauma, PTSD, and anxiety. They are also at increased risk of using other substances like tobacco, marijuana, and cocaine. Poor nutrition and disrupted social support systems are common challenges. Identifying these issues and providing multidisciplinary care is crucial for optimal outcomes.
Universal Screening for Opioid Use and Opioid Use Disorder in Pregnancy: Why It Matters for Every Woman
Screening for substance use must be an integral part of comprehensive obstetric care, conducted at the first prenatal visit in partnership with the pregnant woman. Substance use disorders affect women across all demographics – racial, ethnic, socioeconomic, and geographic. Screening based on risk factors like poor prenatal care adherence or prior adverse pregnancy outcomes is insufficient, leading to missed cases and reinforcing stereotypes. Therefore, universal screening is essential; no woman should be assumed “not in testing for cars medication tools” and thus exempt from screening. All pregnant women should be routinely asked about alcohol and drug use, including prescription opioids and non-medical medication use. Explaining that these questions are standard for all pregnant women can facilitate open communication. A caring, non-judgmental approach and screening in private are crucial for honest disclosure. Patient autonomy, confidentiality, and the patient-physician relationship must be protected within legal boundaries. Obstetric care providers should be aware of varying state reporting mandates.
Validated screening tools like the 4Ps, NIDA Quick Screen, and CRAFFT (for women 26 and younger) are recommended for routine screening. These tools are well-validated, highly sensitive, and can be administered through interviews or computer-based approaches.
Alt text: Image displaying Box 2 from the original article, titled “Clinical Screening Tools for Prenatal Substance Use and Abuse,” listing the 4Ps, NIDA Quick Screen, and CRAFFT screening tools with their respective questions and scoring instructions.
Urine drug testing, while used, should only be performed with informed consent and in compliance with state laws. Pregnant women must be informed of potential consequences of positive results, including reporting mandates. Routine urine drug screening is controversial due to limitations: it’s not diagnostic of opioid use disorder, only detects recent use, may not detect all substances, and can produce false positives. Validated verbal screening tools are preferred for initial screening, allowing for brief intervention, education, and motivational interviewing. More severe cases require referral to specialized treatment. Obstetric care providers should be familiar with local substance use treatment resources and collaborate with social service agencies to facilitate referrals and optimize patient care.
Treatment Options for Opioid Use Disorder in Pregnancy
Opioid Agonist Pharmacotherapy: Methadone and Buprenorphine
Opioid agonist pharmacotherapy, also known as medication-assisted treatment (MAT), using methadone combined with counseling and behavioral therapy, has been the standard treatment for heroin addiction during pregnancy since the 1970s. Methadone and buprenorphine are both used to treat opioid use disorder in pregnant women.
MAT is effective because it prevents opioid withdrawal, reduces relapse risk and associated complications, and improves adherence to prenatal care and addiction treatment. It also reduces obstetric complications. Neonatal abstinence syndrome (NAS) is an expected and treatable consequence of prenatal opioid agonist exposure, requiring collaboration with pediatric care providers.
Addiction treatment providers must adhere to federal regulations regarding patient record confidentiality (42 CFR Part 2). Resources for local opioid use disorder treatment programs can be found on the Substance Abuse and Mental Health Services Administration (SAMHSA) website.
Methadone in Pregnancy
Methadone is dispensed daily through registered opioid treatment programs and should be part of a comprehensive treatment plan, including counseling, therapy, and psychosocial services. Methadone dosages are managed by addiction treatment specialists, with communication between the obstetric and addiction treatment teams being crucial. Dosage adjustments may be necessary throughout pregnancy to manage withdrawal symptoms like cravings, cramps, and insomnia. Methadone interacts with other medications and can prolong the QTc interval.
Pregnancy-related pharmacokinetic and physiological changes, especially in the third trimester, may necessitate dose adjustments for women stable on methadone before pregnancy. Split dosages may be needed due to rapid metabolism during pregnancy. Dosage adjustments should be clinically driven.
For women initiating methadone during pregnancy, dosage should be titrated to eliminate withdrawal symptoms following safe induction protocols. Inadequate methadone dosage can cause fetal stress and increase relapse risk. Research indicates that NAS severity is not directly correlated with maternal methadone dosage, so minimizing the dose is not recommended. Split methadone dosing may be associated with lower NAS rates.
Methadone induction typically starts in outpatient opioid treatment programs. Inpatient initiation is possible but requires arrangements for immediate outpatient follow-up. Prescribing methadone for opioid use disorder outside of licensed opioid treatment programs is generally illegal, except in hospital settings.
Buprenorphine in Pregnancy
Buprenorphine is a supported treatment option for opioid use disorder during pregnancy. As a partial opioid agonist, it has a lower overdose risk than methadone. Advantages include fewer drug interactions, outpatient treatment availability, less need for dosage adjustments during pregnancy, and evidence of less severe NAS. Disadvantages include rare hepatic dysfunction reports, limited long-term infant data, risk of precipitated withdrawal during induction, and diversion potential.
Buprenorphine is available as a monoproduct or combined with naloxone. The monoproduct is generally recommended during pregnancy to avoid potential naloxone exposure, although studies on the combination product have shown no adverse effects. The monoproduct has a higher misuse and diversion potential, requiring monitoring. Unlike methadone, buprenorphine can be prescribed in office-based settings by trained and DEA-approved providers, increasing treatment accessibility and reducing stigma. SAMHSA provides a directory of buprenorphine prescribers. Office-based buprenorphine treatment may be unsuitable for patients needing more intensive structure.
Transitioning from methadone to buprenorphine carries a significant risk of precipitated withdrawal and is not recommended. The long-term effects of buprenorphine use during pregnancy are still being studied. Long-acting buprenorphine implants are approved for non-pregnant individuals but lack data in pregnant women.
Medically Supervised Withdrawal: Not Typically Recommended
Opioid agonist pharmacotherapy is preferred over medically supervised withdrawal for pregnant women with opioid use disorder due to high relapse rates (59-90+%) and poorer outcomes associated with withdrawal. Relapse increases risks of infection, overdose, obstetric complications, and poor prenatal care. If opioid agonist therapy is refused or unavailable, medically supervised withdrawal may be considered with informed consent and under the care of an experienced perinatal addiction specialist. Successful withdrawal often requires prolonged inpatient care and intensive outpatient follow-up. Access to opioid agonist therapy should be prioritized.
Early reports raised concerns about fetal stress and death during opioid withdrawal in pregnancy. More recent studies haven’t clearly linked medically supervised withdrawal to fetal death or preterm delivery, but long-term data, particularly relapse rates, are lacking. Further research is needed to assess the safety, efficacy, and long-term outcomes of medically supervised withdrawal.
Naltrexone: Limited Data in Pregnancy
Naltrexone, an opioid receptor antagonist, is used for abstinence maintenance in non-pregnant individuals. Long-acting injectable naltrexone is more effective than oral forms. Data on naltrexone use in pregnancy is limited to case reports showing normal birth outcomes. Concerns exist regarding unknown fetal effects, relapse risk, and overdose risk upon return to opioid use after treatment dropout. Research on naltrexone during pregnancy is needed but ethically and logistically challenging. Some pregnant women express interest in antagonist treatment. Continuing naltrexone treatment in women already on it before pregnancy requires careful discussion of limited safety data versus relapse risks.
Naloxone: For Overdose Reversal
Naloxone is a short-acting opioid antagonist that rapidly reverses opioid effects and is life-saving in overdose situations. Despite potential fetal stress from induced withdrawal, naloxone should be used in pregnant women experiencing overdose to save the mother’s life. Naloxone can be administered intravenously, subcutaneously, or intranasally by professionals or bystanders. Naloxone kits should be available to patients at overdose risk. Many states allow third-party naloxone prescriptions.
Antepartum, Intrapartum, and Postpartum Care: A Multidisciplinary Approach
Antepartum Care Modifications
Prenatal care for women with opioid use disorder needs to be tailored and comprehensive, addressing specific needs and comorbidities. Key considerations include:
- STI and infectious disease testing: Testing for HIV, hepatitis B and C, chlamydia, gonorrhea, syphilis, and tuberculosis is crucial, with repeat testing in the third trimester for high-risk women. Hepatitis B vaccination is recommended for at-risk women.
- Depression and behavioral health screening: Routine screening for depression and other mental health conditions is essential.
- Ultrasound assessments: In addition to mid-second trimester ultrasound, consider first-trimester ultrasound for accurate dating and interval fetal weight assessment if growth concerns arise.
- Multidisciplinary consultations: Consultations with anesthesia, addiction medicine, pain management, pediatrics, maternal-fetal medicine, behavioral health, nutrition, and social services should be utilized as needed.
- Breastfeeding guidance: Provide anticipatory breastfeeding guidance during prenatal care, as breastfeeding is encouraged for stable women on opioid agonists without contraindications.
- Neonatal care coordination: Close communication between obstetric and pediatric teams before delivery is necessary for optimal neonatal management, with prenatal neonatal consultation considered.
- Substance use cessation: Address and offer cessation services for other substance use, particularly tobacco, which is common in this population.
Intrapartum Pain Management
Women on methadone or buprenorphine during labor should continue their maintenance dose and receive additional pain relief. Epidural or spinal anesthesia should be offered when appropriate. Opioid agonist-antagonist drugs like butorphanol and nalbuphine should be avoided as they can precipitate withdrawal in patients on opioid agonists. Some units have removed these drugs from formularies to prevent inadvertent withdrawal precipitation. Buprenorphine should not be given to women on methadone. Pediatric staff must be informed of all opioid-exposed infants to ensure NAS screening.
Patients on methadone or buprenorphine may require higher opioid doses for analgesia due to tolerance. Adequate pain relief can be achieved with short-acting opioids and anti-inflammatory medications. Injectable NSAIDs like ketorolac are effective for postpartum pain. Maintain daily methadone or buprenorphine doses during labor and postpartum to prevent withdrawal. Dividing the daily dose may offer partial pain relief, but additional analgesia is usually needed. Intrapartum and postpartum pain management can be challenging due to tolerance and hypersensitivity. Anesthesia consultation can be beneficial for developing individualized pain management plans using multimodal approaches including neuraxial analgesia, NSAIDs, and acetaminophen.
Postpartum Care and Relapse Prevention
Breastfeeding is encouraged for women on methadone or buprenorphine, associated with reduced NAS severity, less need for infant pharmacotherapy, and shorter hospital stays. It also promotes mother-infant bonding and immunity. Breastfeeding is recommended for stable women on opioid agonists without contraindications like HIV. Women should be counseled to stop breastfeeding upon relapse. The American Academy of Pediatrics supports breastfeeding for women on methadone and buprenorphine regardless of maternal dose due to minimal drug transfer to breast milk. However, codeine and tramadol are contraindicated during breastfeeding due to potential infant opioid overdose risk. If codeine is considered necessary, risks and benefits should be discussed.
Immediate postpartum methadone dosage reduction is generally not needed. Dosage reductions postpartum should be titrated based on sedation signs. Most women on buprenorphine can continue their pre-delivery dose. Caution should be used with other sedating medications.
Postpartum opioid agonist pharmacotherapy should continue due to increased relapse vulnerability in the postpartum period, triggered by factors like loss of treatment access, new baby demands, sleep deprivation, and custody concerns. Postpartum depression and other psychiatric disorders are common and require screening. Substance use is a major contributor to pregnancy-associated deaths. Access to postpartum psychosocial support, substance use disorder treatment, and relapse prevention programs is crucial. Overdose training and naloxone coprescribing are recommended.
Unintended pregnancy rates are high among women with substance use disorders. Contraceptive counseling, including immediate postpartum long-acting reversible contraception, should be routinely offered.
Neonatal Abstinence Syndrome (NAS): Management and Care
Neonatal abstinence syndrome (NAS) is an expected and treatable drug withdrawal syndrome in 30-80% of infants exposed to chronic maternal opioid use. Symptoms include irritability, high-pitched cry, poor sleep, and feeding difficulties. NAS onset varies depending on the opioid, with methadone-exposed infants showing symptoms within 2 weeks, typically within 72 hours, lasting days to weeks. Buprenorphine-exposed infants usually show symptoms within 12-48 hours, peaking at 72-96 hours and resolving within 7 days. Other substances like nicotine and SSRIs may increase NAS severity. Validated screening tools like the Finnegan Scale and standardized treatment protocols improve infant outcomes. Each nursery should have evidence-based NAS policies, and families should be informed about key policy components. Family involvement in infant care and breastfeeding should be encouraged. Perinatal quality initiatives offer resources for optimizing NAS diagnosis and treatment and promoting obstetric-neonatal collaboration.

Long-Term Infant Outcomes: The Importance of Support
Long-term outcomes of infants with in utero opioid exposure have been studied, but isolating opioid effects from confounding factors like polysubstance use, socioeconomic status, and poor prenatal care is challenging. Most studies show no significant cognitive development differences up to age 5 between methadone-exposed children and matched controls, although scores may be lower than population norms in both groups. Preventive interventions focused on supporting mothers and caregivers, enriching early childhood experiences, and improving the home environment are likely beneficial.
Conclusion: A Call for Universal Screening and Comprehensive Care
Early universal screening, brief intervention, and referral to treatment for pregnant women with opioid use and opioid use disorder improve maternal and infant outcomes. Contraceptive counseling and access to services are essential in substance use disorder treatment to minimize unintended pregnancies. Pregnancy in women with opioid use disorder requires co-management by obstetric and addiction medicine providers, with appropriate information sharing consents. Tailoring prenatal care to individual needs, ensuring continuous medication dosing, and prioritizing opioid agonist pharmacotherapy over medically supervised withdrawal are crucial. Infants born to women using opioids during pregnancy require monitoring for NAS. Multidisciplinary long-term follow-up, including medical, developmental, and social support, is vital. A coordinated, multidisciplinary approach without criminal sanctions offers the best chance for helping families affected by opioid use disorder during pregnancy. Obstetric care providers have an ethical responsibility to advocate against separating parents from children solely based on substance use disorder.
