What treatment is typically prescribed for cystitis?

Cystitis, which is an inflammation of the bladder often caused by a urinary tract infection (UTI), is commonly treated with antibiotics to effectively target the underlying infection. Nitrofurantoin is a specific antibiotic frequently prescribed for uncomplicated UTIs, including cases of cystitis.

This medication works by interfering with bacterial cell wall synthesis and functions well against many common pathogens associated with urinary tract infections. It's particularly effective due to its ability to be concentrated in the urine, directly targeting the bacteria within the bladder.

Other options provided do not address the bacterial infection that causes cystitis. Diphenhydramine is an antihistamine that may be used to relieve allergy symptoms but does not treat infections. Proton pump inhibitors are used to reduce gastric acid production and are not relevant to urinary tract infections. Antipsychotics serve to manage psychiatric disorders and have no therapeutic effect on cystitis. Therefore, nitrofurantoin is the most appropriate and effective treatment for this condition.
