Opioid Use Can Lead to Pregnancy Loss, Decrease Chance of Conception

Opioid usage could lower the chance of conceiving. And, use in early pregnancy may be associated with a greater chance of pregnancy loss, according to the study in Epidemiology.

"Our findings indicate that women who are pregnant or planning a pregnancy should, along with their physicians, consider the potential effects opioids may have on their ability to conceive or sustain a pregnancy," said Kerry Flannagan, Ph.D., the primary author of the study and a postdoctoral researcher in the Division of Intramural Population Health Research at NIH's Eunice Kennedy Shriver National Institute of Child Health and Human Development.

According to the authors, much of the research on prescription opioid use has focused on the effects of drug dependency. Little information exists on non-habitual, periodic opioid use around the time of conception and early in pregnancy.

The researchers analyzed data from the Effects of Aspirin in Gestation and Reproduction (EAGeR) trial, which investigated low-dose aspirin as a treatment to prevent pregnancy loss. Participants were women from 18 to 40 years old with a history of one or two pregnancy losses.

Women were followed for six monthly cycles if they did not get pregnant and throughout pregnancy if they did. The women provided urine samples, which were analyzed for various prescription opioids.

Of the 1,228 women in the study, 226 (18%) had used opioids while trying to conceive and 33 (5%) of 685 women who became pregnant had used opioids in early pregnancy. None tested positive for methadone or buprenorphine, typically used to treat opioid dependence.

Opioid use before conception was associated with a 29% lower chance of achieving pregnancy during a given monthly cycle, compared to women who had not used opioids. Among the women who became pregnant, those who used opioids around the time of conception were 1.5 times as likely to have a miscarriage as women who had not.

Prescription Drug Abuse
Prescription drug abuse is consuming prescription medications in a way different from that as prescribed by the doctor. It is becoming a colossal health problem which can lead to addiction and even death.

Women who used opioids in the first four weeks of pregnancy were more than twice as likely to have a miscarriage. Women who used opioids in weeks four through eight of pregnancy were 2.5 times as likely to have a miscarriage.

The authors called for additional research on how opioid use affects fertility and early pregnancy. They added that until more is known, patients and physicians should evaluate the potential risks and benefits of opioids for pain management among women who are pregnant or may become pregnant, including those undergoing assisted reproduction procedures that may involve opioid treatment to manage pain.
