How to Use This Medicine:

Thin Sheet, Tablet

  • Take your medicine as directed. Your dose may need to be changed several times to find what works best for you.
  • You must let the medicine dissolve. Never swallow the film or tablet. Your body may not absorb enough of the medicine if you swallow it.
  • Your health caregiver should show you how to use the medicine. If you do not understand, ask for help. It is important to use the medicine correctly. Do not talk while the medicine is in your mouth.
  • Buccal film: Use your tongue to wet the inside of your cheek, or rinse your mouth with water. Place the side of the film with the text (BN2, BN4, or BN6) against the inside of your cheek. If your doctor told you to use more than 1 film, place the second film inside your other cheek. Do not place more than 2 films inside of 1 cheek at a time. Do not move or touch the film. Do not eat or drink anything until the film is completely dissolved.
  • Sublingual tablet: Place the tablet under your tongue. If your doctor told you to use more than 1 tablet, place all of the tablets under your tongue together. You can use 2 tablets at a time until you have taken all of the medicine, if that is easier for you. Let the tablets dissolve completely in your mouth. Do not eat or drink anything until the tablets are completely dissolved.
  • Sublingual film: Drink some water to help moisten your mouth. Place the film under your tongue. If your doctor told you to use more than 1 film, place the second film on the opposite side from the first one. Do not move the film after you place it under your tongue. If you are supposed to use more than 2 films, use them the same way, but do not start until the first 2 films are completely dissolved.
  • Do not break, crush, chew, or cut the film or tablet.
  • This medicine should come with a Medication Guide. Ask your pharmacist for a copy if you do not have one.
