Preventing Bladder Infections in Women

Preventing Bladder Infections in Women

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)
