What is a common treatment for recurrent cystitis in pregnant patients?

Nitrofurantoin is commonly used to treat recurrent cystitis in pregnant patients due to its efficacy and safety profile. It specifically targets urinary tract infections (UTIs), making it effective against common uropathogens responsible for cystitis. Importantly, it has a long history of use and is generally considered safe during pregnancy, particularly in the second trimester.

While other antibiotics can also be effective in treating UTIs, they may carry risks that make them less suitable for pregnant women. For example, ciprofloxacin is a fluoroquinolone that is not typically recommended during pregnancy due to potential effects on fetal development. Trimethoprim-sulfamethoxazole is contraindicated in the first trimester and near delivery due to potential risks of neural tube defects and hyperbilirubinemia in newborns, respectively. Although amoxicillin is often considered safe, it may not be as effective as nitrofurantoin for recurrent UTIs.

Thus, nitrofurantoin stands out as a preferred option due to its targeted action, effectiveness, and safety profile in pregnant women suffering from recurrent cystitis.
