From the Guidelines

Most antibiotics used to treat urinary tract infections (UTIs) are safe during breastfeeding, with first-line options including nitrofurantoin, trimethoprim-sulfamethoxazole, and cephalosporins like cephalexin. These medications pass into breast milk in very small amounts that are generally considered safe for nursing infants 1. A typical regimen for uncomplicated UTIs is 3-7 days, depending on the specific antibiotic prescribed. While breastfeeding, it's essential to stay well-hydrated and continue nursing regularly, as these antibiotics don't require pumping and dumping. However, some antibiotics like fluoroquinolones (ciprofloxacin, levofloxacin) are usually avoided during breastfeeding if alternatives are available 1. Always inform your healthcare provider that you're breastfeeding so they can select the most appropriate antibiotic. Watch for potential side effects in your baby such as diarrhea, thrush, or skin rash, though these are uncommon. The benefits of treating a maternal UTI typically outweigh the minimal risks to the nursing infant, as untreated UTIs can progress to more serious kidney infections.

Some key points to consider when choosing an antibiotic for a breastfeeding mother with a UTI include:

  • Nitrofurantoin is a common first-line option, but its use should be limited to 5 days due to the risk of pulmonary toxicity 1
  • Trimethoprim-sulfamethoxazole is another first-line option, but it should be avoided in the first 8 weeks postpartum due to the risk of kernicterus in the newborn 1
  • Cephalosporins like cephalexin are generally considered safe during breastfeeding, but their use should be limited to 3-7 days due to the risk of antibiotic resistance 1
  • Fluoroquinolones like ciprofloxacin and levofloxacin should be avoided during breastfeeding if alternatives are available due to the risk of cartilage damage in the developing infant 1

It's essential to consult with a healthcare provider to determine the best course of treatment for a UTI during breastfeeding, as they can assess the individual situation and choose the most appropriate antibiotic. The healthcare provider should also monitor the mother and baby for any potential side effects or complications. By prioritizing the safety and well-being of both the mother and the baby, healthcare providers can ensure the best possible outcomes for breastfeeding mothers with UTIs.

From the FDA Drug Label

  1. 3 Nursing Mothers Penicillins have been shown to be excreted in human milk. Amoxicillin use by nursing mothers may lead to sensitization of infants. Caution should be exercised when amoxicillin is administered to a nursing woman.

Use of amoxicillin during nursing is not strictly contraindicated, but caution should be exercised due to the potential for sensitization of infants 2, 2. Monitoring of the infant for signs of sensitization or other adverse effects is recommended.

From the Research

UTI Antibiotics and Nursing

  • The use of antibiotics for urinary tract infections (UTIs) during nursing is a common practice, but it requires careful consideration of the type of antibiotic and the patient's specific needs 3, 4.
  • For nursing home patients, oral antibiotics are often sufficient for treating cystitis, while parenteral agents may be necessary for pyelonephritis 4.
  • First-generation oral cephalosporins, such as cephalexin, can be effective for uncomplicated lower urinary tract infections (uLUTIs) and may be used as a fluoroquinolone-sparing alternative 5.
  • During pregnancy, UTIs can increase the risk of maternal and neonatal morbidity and mortality, and asymptomatic bacteriuria should be treated to prevent complications 6.
  • Nurses play a crucial role in the management of UTIs, including diagnosis, treatment, and prevention, and can promote patient wellbeing and empowerment through education and support 7.

Antibiotic Options

  • Nitrofurantoin, fosfomycin, and pivmecillinam are recommended first-line empiric antibiotic therapies for acute uncomplicated bacterial cystitis in otherwise healthy adult nonpregnant females 3.
  • Second-line options include oral cephalosporins, such as cephalexin or cefixime, fluoroquinolones, and β-lactams, such as amoxicillin-clavulanate 3.
  • For UTIs caused by extended-spectrum β-lactamases (ESBLs)-producing Enterobacteriales, treatment options include nitrofurantoin, fosfomycin, pivmecillinam, amoxicillin-clavulanate, finafloxacin, and sitafloxacin 3.

Considerations for Nursing

  • Nurses should be aware of the potential for antibiotic resistance and the importance of accurate diagnosis and treatment 3, 7.
  • Patient education and support are crucial in preventing UTIs and promoting recovery 7.
  • Nurses should be familiar with the different types of antibiotics and their uses, as well as the potential side effects and interactions 3, 5.
