trimethoprim tablets for cystitis

Cystitis is an infection or inflammation of the bladder that follows a bacterial infection in the urine. It is the most common type of urinary tract infection (UTI), particularly in women. The bladder is a muscular bag that stores urine from the kidneys before the urine leaves the body through a tube called the urethra. Cystitis can occur when urine and the bladder lining become infected after bacteria enters the urethra.
