From the Guidelines

Azithromycin can be used to treat typhoid fever in pregnancy, as it is considered safe and effective, with a good safety profile in pregnancy and effectiveness against Salmonella Typhi, including many drug-resistant strains. The most recent and highest quality study, 1, suggests that azithromycin is safe in pregnancy, with no adverse effects reported. This is in line with other studies, such as 1 and 1, which also support the use of azithromycin in pregnancy.

Key Points to Consider

  • Azithromycin is classified as FDA pregnancy category B, meaning animal studies have not shown risk to the fetus, and there are no adequate studies in pregnant women showing adverse effects 1.
  • The typical treatment regimen is 500 mg of azithromycin once daily for 7 days, though this may vary based on severity and clinical response.
  • Treatment should be started promptly after diagnosis, as untreated typhoid fever poses significant risks to both mother and fetus, including miscarriage, preterm labor, and maternal complications.
  • Adequate hydration, rest, and fever management are also important components of treatment.
  • Any pregnant woman with suspected typhoid fever should receive immediate medical attention for proper diagnosis and treatment.

Important Considerations

  • Azithromycin is preferable to fluoroquinolones like ciprofloxacin, which are generally avoided during pregnancy due to potential risks to the fetus 1.
  • Other antibiotics, such as doxycycline, are contraindicated in pregnancy due to increased hepatotoxicity and staining of fetal teeth and bones 1.
  • Beta-lactam antibiotics and aminoglycosides may be used as needed, but with caution and careful monitoring 1.

From the Research

Azithromycin for Typhoid in Pregnancy

  • Azithromycin can be used to treat typhoid fever, but its use in pregnancy requires careful consideration of the potential risks and benefits 2.
  • There is no conclusive evidence to support that azithromycin use by pregnant women causes adverse outcomes in their offspring, but some studies have reported increased risks of spontaneous miscarriage, major congenital malformations, and preterm birth 2.
  • A study comparing the efficacy and safety of azithromycin and ofloxacin in uncomplicated typhoid fever found that azithromycin was an effective alternative, with no major adverse effects, and may be suitable for use in pregnant women 3.
  • However, other studies have highlighted the potential risks of antibiotic resistance and the need for careful selection of antibiotic therapy in pregnant women with typhoid fever 4, 5.
  • The use of azithromycin in pregnancy should be based on clinical judgment, weighing the potential benefits against the potential risks, and considering alternative treatment options 2, 3.

Treatment of Typhoid Fever in Pregnancy

  • Typhoid fever in pregnancy can be treated with various antibiotics, including chloramphenicol, ampicillin, and amoxicillin, but the choice of therapy should be guided by susceptibility testing and clinical experience 6, 5.
  • Azithromycin may be a suitable alternative for the treatment of typhoid fever in pregnancy, particularly in cases where other antibiotics are contraindicated or resistant 3.
  • The management of typhoid fever in pregnancy requires careful monitoring and follow-up to ensure the best possible outcomes for both the mother and the fetus 4, 5.
