Is it safe to take oxycodone during pregnancy?

Written by Brandon Okey. Mina Draskovic, B.Psy., reviewed this content for accuracy.

You should avoid oxycodone during pregnancy. Oxycodone is an opioid that crosses the placenta and causes serious complications, including birth defects, preterm labor, and neonatal withdrawal syndrome in newborns.

A 2017 study shows that oxycodone use during the first trimester raises the risk of heart defects and neural tube defects in babies. Even brief exposure can cause respiratory depression in newborns and developmental challenges later in childhood.

Why do pregnant women use oxycodone?

Oxycodone is a powerful prescription opioid that treats moderate to severe acute pain and chronic pain conditions. The Food and Drug Administration classifies it as a Schedule II controlled substance due to its high potential for abuse and addiction. This semi-synthetic opioid analgesic binds to mu-opioid receptors in the brain and spinal cord, blocking pain signals while creating euphoric effects.

Despite its risks, pregnant women may use oxycodone for:

  • Pre-existing chronic pain conditions.
  • Acute pain during pregnancy.
  • Pregnancy-related complications.
  • Existing opioid dependence.
  • Coping with trauma.
  • Treating mental health conditions
  • Quitting another addiction.

The stress and physical changes of pregnancy can trigger the misuse of opioids, creating complex problems for mother and baby.

How oxycodone affects fetal development and babies

Oxycodone crosses the placenta and accumulates in fetal tissues, where it disrupts development throughout pregnancy. When it attaches to receptors in the baby’s developing brain and nervous system, oxycodone interferes with growth processes.

Birth defects and physical development

According to a CDC systematic review of 68 studies, taking oxycodone during your first trimester raises the risk of birth defects, especially heart problems and spinal cord defects. This early pregnancy period is when your baby’s organs form, so they are particularly vulnerable to opioid medications.

The review also shows that opioid exposure during pregnancy causes babies to weigh less at birth, about 200–300 grams below normal. Growth problems worsen when mothers continue using oxycodone throughout pregnancy, particularly during the final three months when the baby’s brain develops rapidly.

Neonatal opioid withdrawal syndrome

Babies exposed to oxycodone during pregnancy can develop neonatal withdrawal symptoms. A 2023 study found that 8.8% of babies with third-trimester oxycodone exposure developed neonatal abstinence syndrome, while other studies report rates that go up to 29.5%.

These newborns may experience tremors, excessive crying, feeding difficulties, and breathing problems. Symptoms typically begin within three days after birth and can persist for weeks.

Brain development and long-term effects

Your baby’s developing brain is especially vulnerable to opioid exposure. A 2015 research review found that chronic opioid exposure during pregnancy can lead to cognitive and behavioral problems in infants and preschool-aged children. Studies show impairments in cognitive development, motor skills, and behavioral outcomes. 

A 2020 animal study found that oxycodone exposure altered brain genes involved in synaptic function and led to anxiety-like behaviors and social problems that persisted across generations.

These studies are just a portion of the potential risks. The most important step is addressing oxycodone dependence before it impacts your family. At Ardu, we help individuals overcome oxycodone and other substance use disorders (SUDs) through evidence-based treatment and personalized care.

How oxycodone affects pregnant mothers

Pregnant women on oxycodone face serious health complications beyond normal opioid addiction risks. A 2021 study looked at over 9,800 pregnant women and found that the most serious effects of oxycodone use on expectant mothers are:

  • Increased surgical delivery risks: Oxycodone use increases your risk of C-section delivery and operative vaginal delivery complications.
  • Severe bleeding after delivery: Women using oxycodone face higher rates of postpartum hemorrhage, creating dangerous blood loss situations.
  • Depression during pregnancy: Opioid use during pregnancy is associated with an increased risk of developing depression. The higher the oxycodone dose, the stronger the connection to depression.
  • Dangerous heart complications: Pregnant women on oxycodone face an increased risk of serious cardiac events that can threaten mother and baby.
  • Increased need for anesthesia during labor: Women using higher doses of opioids more frequently require epidural or spinal anesthesia during delivery.

Many women who take oxycodone when pregnant find themselves needing higher doses as their bodies build tolerance, which can lead to addiction. The drug can also slow down your breathing, especially when mixed with other medications during labor, putting both of you at risk.

If you try to stop taking oxycodone, withdrawal symptoms can be dangerous for you and your baby. Our specialized detox program helps you safely withdraw from oxycodone while protecting your health and your baby’s development.

Can oxycodone cause a miscarriage?

Opioid use during early pregnancy may cause a miscarriage. Studies reveal higher pregnancy loss rates in women using opioids during the first trimester than in unexposed pregnancies. Giovannini, et. al. found that “opioid abuse exposes the fetus to multiple episodes of intoxication and withdrawal,” potentially leading to intrauterine fetal death.

Oxycodone activates opioid receptors throughout your reproductive system, which disrupts placental development and cuts off fetal blood flow. The drug also disrupts embryo implantation. Giovannini, et. al. also show that opioids “increase the risk of placental abruption” and cause “chronic placental insufficiency.”

The drug disrupts reproductive hormones, damaging egg quality and early embryo development. While first-trimester oxycodone exposure doesn’t increase birth defects, a 2023 study found that second-trimester use doubled mortality rates compared to unexposed pregnancies.

Women who use opioids typically struggle with poor nutrition and skip prenatal care appointments, and many use additional substances that compound pregnancy risks. The most dangerous period occurs during the 6–12 day implantation window when the embryo attaches to the uterine wall. Second-trimester exposure multiplies the risk of very preterm birth by five, creating life-threatening situations for newborns. 

We address these complex challenges through medically supervised care and help women break free from opioid dependence while protecting their health and their baby’s future.

Can you breastfeed while taking oxycodone?

Breastfeeding while taking oxycodone isn’t recommended. The drug passes into breast milk at concentrations three times higher than what’s in your blood, which means your baby gets a concentrated dose every time they nurse.

A 2024 Finnish study found that oxycodone appears in every breast milk sample tested, with the highest concentrations occurring within the first 24 hours after taking the medication. The drug stays detectable in breast milk for up to 40 hours after your last dose. In most cases, babies receive less than 10% of the maternal dose through nursing, but some infants can be more sensitive than others.

A Canadian study found that 20% of breastfed babies whose mothers used oxycodone showed signs of drowsiness and feeding difficulties. 

Your doctor will likely suggest safer pain relief options first that will have the least effect on your baby.

Which painkillers are safe during pregnancy?

Most prescription opioids are unsafe during pregnancy. Some pain management options pose fewer dangers to your developing baby. These include:

  • Acetaminophen.
  • Ibuprofen (limited use).
  • Non-drug approaches (e.g., physical therapy, prenatal massage, acupuncture, and heat therapy).

If you’re dealing with severe pain that requires opioid therapy, your doctor may choose short-term, low-dose alternatives under close supervision.

Oxycodone and pregnancy FAQ

Can I take codeine in early pregnancy?

Avoid codeine during early pregnancy. Like oxycodone, codeine crosses the placenta and can cause congenital anomalies, congenital heart defects, and affect fetal growth. Early pregnancy is when your baby’s organs form, making them most vulnerable to opioids.

Your doctor can recommend safer options, like acetaminophen or physical therapy. If you’re taking codeine and discover you’re pregnant, contact your healthcare provider immediately for risk assessment.

What shouldn’t be mixed with oxycodone?

Never mix oxycodone with alcohol, benzodiazepines, or other CNS depressants. These combinations increase opioid overdose risk and perinatal mortality. Avoid muscle relaxers, sleep aids, and nonsteroidal anti-inflammatory drugs unless your doctor approves. During pregnancy, these drug interactions can cause respiratory depression and maternal toxicity, affecting you and your baby’s neurodevelopmental outcomes.

Always tell your healthcare provider about all opioid medications and supplements you’re taking.

Is oxycodone stronger than morphine?

Oxycodone is about 1.5 times stronger than morphine when taken orally. Both are powerful opioids that bind to receptors in your brain and affect fetal development. During pregnancy, both pose risks, including congenital heart defects, fetal growth restriction, and neonatal withdrawal. 

Does oxycodone make you sleepy?

Oxycodone causes drowsiness and sedation by affecting your central nervous system and blood-brain barrier. This sleepiness increases fall risk during pregnancy and indicates the drug is crossing the placenta at levels that could cause fetal effects.

If you experience significant drowsiness, contact your doctor immediately. They may need to adjust your opioid treatment program or find safer pain management alternatives to prevent maternal and infant health complications.

Does oxycodone affect getting pregnant?

Oxycodone can interfere with fertility by disrupting the reproductive hormones that impact ovulation and egg quality. It may affect your menstrual cycle and interfere with implantation when the fertilized egg attaches to the uterine wall. Maternal drug use can also impact fetal-placental development and cause feeding problems later. If you’re trying to conceive, discuss alternatives with your doctor.
