13 Things to Know About Medication During Pregnancy — From a Medical Perspective
9. Antibiotics and Infection Management During Pregnancy
Antibiotic selection during pregnancy requires careful consideration of both maternal infection treatment needs and fetal safety, as untreated infections can pose significant risks to pregnancy outcomes while certain antibiotics carry specific contraindications or concerns. Penicillins and cephalosporins are generally considered first-line antibiotics during pregnancy due to extensive safety data and lack of teratogenic effects, making them preferred choices for common infections including urinary tract infections, respiratory tract infections, and group B streptococcus prophylaxis. Macrolides, particularly erythromycin and azithromycin, are generally safe alternatives for patients with penicillin allergies, though clarithromycin has raised some concerns about cardiovascular malformations and is typically avoided. Clindamycin is considered safe and effective for anaerobic infections and as an alternative for group B streptococcus prophylaxis in penicillin-allergic patients. However, several antibiotic classes are contraindicated during pregnancy due to specific fetal risks: tetracyclines cause tooth discoloration and bone growth inhibition, fluoroquinolones may affect cartilage development, and aminoglycosides carry risks of eighth cranial nerve damage and nephrotoxicity. Sulfonamides are generally avoided near term due to risks of kernicterus from bilirubin displacement. Nitrofurantoin is commonly used for urinary tract infections but is avoided near term due to potential hemolytic anemia in glucose-6-phosphate dehydrogenase-deficient newborns. The management of specific infections during pregnancy often requires specialized considerations: urinary tract infections require prompt treatment to prevent pyelonephritis and preterm labor, while bacterial vaginosis treatment may help reduce preterm birth risks. The principle guiding antibiotic use in pregnancy is that untreated bacterial infections pose greater risks to maternal and fetal health than appropriate antibiotic therapy, making prompt, appropriate treatment essential while avoiding unnecessary or prolonged antibiotic exposure.
10. Pain Management Strategies and Analgesic Safety
Pain management during pregnancy requires a multifaceted approach that balances effective maternal symptom relief with fetal safety considerations, incorporating both pharmacological and non-pharmacological interventions tailored to the specific type and severity of pain. Acetaminophen remains the first-line analgesic for mild to moderate pain during pregnancy, with extensive safety data supporting its use at recommended doses throughout all trimesters, though recent studies suggesting potential associations with neurodevelopmental outcomes warrant continued research and judicious use. Nonsteroidal anti-inflammatory drugs (NSAIDs) present timing-specific considerations, with ibuprofen and naproxen generally avoided in the first trimester due to potential cardiovascular malformation risks and contraindicated after 30 weeks gestation due to effects on fetal ductus arteriosus closure, decreased amniotic fluid, and potential complications during labor and delivery. Topical analgesics and anti-inflammatory preparations may offer localized relief with minimal systemic absorption, though even topical preparations require consideration of their active ingredients and potential for systemic effects. Opioid medications present complex considerations during pregnancy, as while they may be necessary for severe pain conditions, they carry risks of neonatal abstinence syndrome with chronic use and require careful monitoring and tapering strategies
