How to Use This Medicine:

Cream, Suppository

  • Your doctor will tell you how much medicine to take and how often. Wash your hands before and after using this medicine.
  • The medicine is a cream that is in a tube. You will use an applicator to put the cream into your vagina. The applicator is an empty plastic tube called a barrel that is open at one end and has a plunger at the other end.
  • Remove the cap from the end of the tube of cream. Squeeze the cream from the tube into the open end of the applicator until the barrel is filled with cream.
  • If you are using the vaginal suppository, unwrap the suppository and place it in the applicator with the pointed side up. You may wet the suppository with warm water or a water soluble lubricating gel (K-Y® Jelly). You should not use petroleum jelly (Vaseline®).
  • Put the applicator into your vagina as far as you can and push the plunger all the way in. Remove the applicator and wash it with warm, soapy water.
  • Wear only clean cotton underwear (panties) instead of nylon or rayon underwear. The medicine will come out of your vagina, so wear a minipad or sanitary napkin to protect your clothing.
