Introduction
This article is the second in a two-part series on prenatal acetaminophen. The first article examined a new Danish study—the COPANA cohort—which found associations between fetal paracetamol exposure and altered markers of ovarian development, as well as reduced uterine volume, in infant girls.
That study did not conclude that pregnant women should avoid acetaminophen altogether. In fact, its authors and major medical organizations alike emphasize that untreated fever and pain during pregnancy pose far greater risks than appropriate medication use.
But the study did leave many readers asking a practical question: What can I do instead when symptoms are mild?
This follow-up article shifts from science to practice. It picks up where the research left off and focuses on what pregnant women can actually do—evidence-based, non-drug strategies for managing fever, back and pelvic pain, and cold symptoms. It also clarifies when self-care is enough and when medical treatment, including acetaminophen, becomes the safer choice.

Managing Mild Fever
Fever during pregnancy deserves careful attention. A temperature above 38.5°C that does not respond to physical cooling, or fever lasting more than 24–48 hours, warrants prompt medical evaluation.
For low-grade fever (below 38.5°C), physical cooling methods can be effective:
- Cool compress application: Apply a cool, damp towel to areas with rich blood flow—the neck, armpits, and groin—to help release heat from the body.
- Lukewarm sponge baths: These can help lower body temperature gradually.
- Adequate hydration: Fever increases fluid loss. Drink water, diluted fruit juice, or warm broths to support recovery.
- Rest in a cool environment: A well-ventilated room supports the body’s natural cooling mechanisms.
When fever requires medical attention: High fever, particularly in the first trimester, has been associated with neural tube defects and other complications. The American College of Obstetricians and Gynecologists states clearly that fever can be dangerous for both mother and fetus, and acetaminophen remains the recommended treatment when needed.
Managing Musculoskeletal Pain
Back pain and pelvic girdle pain are among the most common complaints during pregnancy. Up to 6 in 10 women experience low back pain, and around 2 in 10 experience pelvic girdle pain.
Exercise and Physical Therapy
The evidence for exercise as a management strategy is strong. A systematic review and meta-analysis published in the British Journal of Sports Medicine found that prenatal exercise is associated with reduced severity of low back and pelvic girdle pain.
A randomized controlled trial demonstrated that a supervised, structured exercise program—combining aerobic and resistance exercises performed biweekly, plus at least 30 minutes of brisk walking daily—significantly reduced pain intensity and disability scores by the 36th week of pregnancy compared with standard antenatal care alone.
Practical exercise approaches for pelvic girdle pain include:
- Swimming: Reduces gravitational load on the pelvis. Avoid breaststroke if it aggravates pain.
- Core stabilization exercises: Strengthening deep abdominal and pelvic floor muscles provides stability to the pelvis and lower back.
- Pelvic floor exercises: Aim for 24 “squeeze and lift” contractions daily, performed in lying, sitting, and standing positions.
- Walking: Pregnant women should aim for approximately 2.5 hours of walking per week as a baseline activity level.
Heat Therapy
Applying heat to tender areas can help relax tense muscles. Options include hot packs, hot water bottles, or warm baths. Important safety note: Heat should not be applied directly to the baby bump and is best avoided entirely during the first trimester.
Manual Therapies
A systematic review with meta-analysis published in Medicine examined complementary manual therapies for pregnancy-related back and pelvic pain, including massage, spinal manipulation, chiropractic, and osteopathy.
Massage therapy has demonstrated benefits beyond pain relief. A randomized controlled trial found that pregnant women who received twice-weekly massage from their partners from 20 weeks gestation experienced greater reductions in leg pain, back pain, depression, anxiety, and anger compared to a control group. Their partners also reported improved mood and relationship satisfaction.
Acupuncture
Evidence for acupuncture in pregnancy-related pain is mixed but generally supportive. The Cochrane Database of Systematic Reviews examined interventions to prevent and treat low back and pelvic pain during pregnancy.
A network meta-analysis published in Medicine in 2025 concluded that limited evidence indicated music-relaxation therapy may be the most effective non-pharmacologic strategy for alleviating pregnancy-related low back pain, though acupuncture also showed promise.
Safety considerations for acupuncture: Medical doctors have historically been cautious about acupuncture in pregnancy due to mostly anecdotal claims that it can promote abortion. A systematic review on acupuncture safety during pregnancy found no evidence of serious adverse events when performed by trained practitioners. However, sterile needles are essential, and certain acupuncture points (such as SP6) should be avoided.
Activity Modification and Pacing
Practical self-management strategies can make a significant difference in daily comfort:
- Pacing: Switch between sitting and standing every 5–10 minutes. Rest before pain becomes severe.
- Standing posture: Stand tall with shoulders, hips, and ankles in line. Avoid letting hips sway forward.
- Sitting: Sit with the base of the spine against the backrest, feet flat on the floor or on a footrest. Use a rolled towel for lower back support if needed.
- Sleeping: Sleep on your side with a pillow between your knees. A small pillow under the stomach can provide additional support.
- Getting out of bed: Roll onto your side, keep knees together, and push up sideways with your arms.
- Car travel: Place a plastic bag on the seat to help swivel into position; remove it before driving.
- Stairs: Use the rails for support. Lead upstairs with the stronger leg and downstairs with the weaker leg.
- Footwear: Wear shoes with gentle arch support and cushioned soles. Avoid slippers or walking barefoot, which may worsen symptoms.
Managing Colds and Respiratory Symptoms
For mild cold symptoms, supportive measures can provide relief without medication:
- Nasal congestion: Inhale steam from a hot shower or use a humidifier to maintain indoor humidity at 50–60%. Saline nasal sprays or rinses offer a safe way to clear nasal passages.
- Sore throat: Gargling warm salt water several times daily can reduce discomfort.
- Rest and hydration: Standard supportive care remains the foundation of cold management.
What to Avoid
Do Not Substitute NSAIDs
Pregnant women should not substitute ibuprofen or other non-steroidal anti-inflammatory drugs (NSAIDs) for acetaminophen. NHS guidance explicitly states that NSAIDs such as ibuprofen are generally not recommended during pregnancy.
Herbal Supplements
Many readers assume “natural” means “safe in pregnancy.” The opposite is often true. Certain herbs are contraindicated during pregnancy. Without rigorous evidence and professional guidance, herbal remedies should be avoided.
When Self-Care Is Not Enough
Non-drug methods are appropriate for mild symptoms only. Seek medical attention promptly if you experience:
- Fever above 38.5°C that does not respond to physical cooling
- Fever lasting more than 24–48 hours
- Persistent headache, which can be an early sign of preeclampsia
- Severe or worsening pain that interferes with daily activities or sleep
- Reduced fetal movement
- Difficulty breathing, chest pain, or other concerning symptoms
ACOG emphasizes that pregnant patients should not hesitate to use acetaminophen as directed by their healthcare provider when needed.
The organization states that “maternal fever, headaches as an early sign of preeclampsia, and pain are all managed with the therapeutic use of acetaminophen, making acetaminophen essential to the people who need it”.
A Balanced Approach
Non-drug strategies offer valuable tools for managing mild pregnancy discomforts. Exercise, heat, massage, acupuncture, and activity modification can all play meaningful roles in symptom management.
However, these approaches work best as complements to—not replacements for—appropriate medical care. When fever or pain becomes significant, untreated symptoms pose real risks to both mother and fetus. Acetaminophen remains the recommended first-line treatment when medication is necessary, used at the lowest effective dose for the shortest duration.
Pregnant women should consult their healthcare provider before relying solely on non-pharmacological approaches, particularly if symptoms persist, worsen, or are accompanied by warning signs.
Key Takeaways
- Non-drug methods are appropriate for mild symptoms only and should not replace medical treatment when fever or pain becomes significant.
