From the Guidelines
Acetaminophen (Tylenol) is generally considered the safest pain medication during pregnancy, with a recommended dose of 650-1000 mg every 6 hours, not exceeding 4000 mg daily, as supported by recent studies 1. For most pregnant women experiencing mild to moderate pain, acetaminophen should be the first choice. If acetaminophen isn't effective, consult your healthcare provider before taking any other pain medications. The following key points should be considered when managing pain during pregnancy:
- NSAIDs like ibuprofen (Advil, Motrin) and naproxen (Aleve) should be avoided, especially in the third trimester, as they can cause complications including premature closure of the ductus arteriosus in the baby and potential bleeding issues 1.
- Opioid pain medications require strict medical supervision during pregnancy due to risks of dependency for both mother and baby 1.
- Non-medication approaches like rest, gentle stretching, warm compresses, massage, and physical therapy can also help manage pain safely during pregnancy.
- Acetaminophen works by reducing pain signals in the central nervous system without the anti-inflammatory effects that make NSAIDs problematic during pregnancy.
- Always inform your healthcare provider about any persistent pain during pregnancy as it could indicate an underlying condition requiring treatment.
- For opioid-naïve women, nonsteroidal anti-inflammatory drugs (NSAIDs) and acetaminophen, unless contraindicated, should be given as first-line treatments for pain after a routine vaginal birth or cesarean delivery, with a short course of low-dose opioids considered for severe pain that is not managed effectively by nonopioid options 1.

If pregnant or breast-feeding ask a health professional before use. The FDA drug label does not answer the question.

Safe Analgesics During Pregnancy
The following analgesics are considered safe for use during pregnancy:
- Paracetamol (acetaminophen) is the agent of choice for mild to moderate pain in any stage of pregnancy 2
- Ibuprofen is the non-steroidal anti-inflammatory drug (NSAID) of choice, but its use is contraindicated after 28 weeks of gestation due to the risk of premature closure of the ductus arteriosus and impairment of fetal kidney function 2
- Opioids can be used for severe pain, but their use can lead to neonatal respiratory depression and adaptation disorders, as well as neonatal withdrawal symptoms with long-term therapy 2
- Sumatriptan can be used to treat migraines 2
- Amitriptyline, a well-studied antidepressant, can be used for chronic pain with appropriate indications 2
Precautions and Recommendations
When using analgesics during pregnancy:
- Paracetamol (acetaminophen) should be used with caution, as prenatal exposure may alter fetal development and increase the risk of neurodevelopmental, reproductive, and urogenital disorders 3, 4, 5
- The use of paracetamol (acetaminophen) should be limited to the lowest effective dose for the shortest possible time 3, 4
- Pregnant women should be cautioned against using paracetamol (acetaminophen) unless medically indicated, and should consult with a physician or pharmacist before using it on a long-term basis 3
- The use of paracetamol (acetaminophen) after the sixth month of pregnancy should be as limited as possible due to the risk of prenatal ductus arteriosus closure 6
