From the Guidelines
The safest approach for pregnant patients is to avoid opioids whenever possible, and if necessary, use them at the lowest effective dose for the shortest duration, ideally during the second trimester, as this period is considered to have a lower risk of adverse effects on the fetus compared to the first and third trimesters. When considering opioid use in pregnant patients, it's crucial to weigh the benefits against the potential risks, including neonatal abstinence syndrome, birth defects, and developmental issues 1. The American College of Obstetricians and Gynecologists and other societies recommend that all pregnant women be screened for substance use disorder at the first prenatal visit, and those with opioid use disorder should be offered maintenance therapy with methadone or buprenorphine 1.
For pain management during pregnancy, nonsteroidal anti-inflammatory drugs (NSAIDs) and acetaminophen are recommended as first-line treatments, unless contraindicated, with opioids considered only for severe pain that is not managed effectively by nonopioid options 1. The choice between methadone and buprenorphine for opioid use disorder should be individualized, considering factors such as the patient's history of response to these medications, availability of prescribers, and potential for engagement with healthcare providers 1.
Key considerations for opioid use in pregnancy include:
- Using the lowest effective dose for the shortest duration possible
- Preferably using short-acting opioids for acute pain management
- Tapering opioid use before delivery when possible to reduce the risk of neonatal abstinence syndrome
- Monitoring patients closely for side effects
- Considering non-opioid pain management strategies first, including acetaminophen and physical therapy
- Individualizing treatment for opioid use disorder, considering the patient's specific needs and circumstances 1.
From the Research
Safer Period for Opioid Use in Pregnant Patients
There is limited information available on the safer period for pregnant patients to receive opioids. However, the following points can be considered:
- The use of opioids during pregnancy should be avoided or limited to specific cases due to the risk of addiction, overdose, and other side effects 2.
- Combination therapy using a small amount of opioid together with a nonopioid pain reliever may be effective and reduce opioid consumption 3, 4.
- The short-term use of opioids under close clinical supervision, such as in-hospital use of opioid analgesics for postoperative pain, may be appropriate, but even here, combination therapy or nonopioid therapy may be preferred 4.
- Some studies suggest that opioids like fentanyl, nalbuphine, and ketamine may be effective for controlling acute pain in certain patients, but the evidence is limited 5.
Key Considerations
- The risks and benefits of opioid use during pregnancy should be carefully evaluated, and alternative pain management options should be considered whenever possible.
- Combination therapy and nonopioid analgesics may be effective alternatives to opioids for managing pain in pregnant patients.
- Close clinical supervision and monitoring are essential when using opioids during pregnancy to minimize the risk of adverse effects.
