What is a common treatment for Chlamydia infection in pregnant women?

Azithromycin is a commonly used treatment for Chlamydia infection in pregnant women due to its effectiveness and safety profile. This macrolide antibiotic is preferred because it has good tissue penetration and is well-tolerated. Azithromycin achieves high cure rates and is single-dose therapy, which is particularly advantageous in managing patients who may have difficulty adhering to a multi-day treatment regimen.

In pregnant women, it is important to choose treatments that do not pose risks to the developing fetus. Azithromycin has been studied and shown to be safe in pregnancy, making it the ideal choice for treating Chlamydia and preventing potential complications such as preterm birth or transmission to the neonate during delivery.

The other options listed do not align with standard guidelines for treating Chlamydia in pregnancy. Metronidazole is primarily used for bacterial vaginosis and trichomoniasis. Ceftriaxone is generally indicated for treating gonorrhea rather than Chlamydia. Valacyclovir is an antiviral medication used for herpes simplex virus infections, which is not applicable in this context.
