In women who experience three or more bladder infections in a year, these measures may help:
Increasing the intake of fluids
Urinating often
Urinating within a short time after sexual intercourse
Avoiding the use of spermicides (used with a diaphragm and/or condom for birth control)
Taking antibiotics continually in low doses
Applying estrogen cream to the vulva or inserting estrogen suppositories into the vagina (postcoital prophylaxis for postmenopausal women who have atrophic vaginitis or atrophic urethritis, if cystitis is frequently related to sexual intercourse)
