- in children under 6 years of age
- in people who have decreased lung volume or an FEV1 less than 40% of predicted
- in people who are colonized with a bacterium called Burkholderia cepacia

Instructions for Use
(tobramycin inhalation solution)
Follow the instructions below for taking BETHKIS. If you have any questions, ask your healthcare provider or pharmacist.
BETHKIS is available as a 28-day supply containing 56 ampules including 14 foil pouches and as a 14-day supply containing 28 ampules including 7 foil pouches. Each foil pouch contains 4 BETHKIS ampules.
Supplies you will need to take BETHKIS (See Figure A):
- 1 ampule of BETHKIS
- PARI LC PLUS reusable nebulizer
- PARI Vios compressor
- tubing to connect the nebulizer and compressor
- clean paper or cloth towels
- nose clips (optional)
BETHKIS is used only in a PARI LC PLUS re-usable Nebulizer connected to a PARI LC PLUS Vios air compressor. Make sure you know how to use your nebulizer machine before you use it to breathe in BETHKIS.
Do not mix BETHKIS with other medicines in your nebulizer.
BETHKIS comes in a sealed foil pouch. Do not open a sealed pouch until you are ready to use a dose of BETHKIS. After opening the pouch, unused ready-to-use ampules should be returned to, and stored in, the pouch.
- Put your PARI LC PLUS Reusable Nebulizer Top and Bottom (Nebulizer Cup) Assembly, Inspiratory Valve Cap, Mouthpiece with Valve, and Tubing on a clean and dry surface.
- Wash your hands with soap and water.
Preparing your BETHKIS dose:
Step 1: Open foil pouch. (See Figure B)
Step 2: Separate 1 ampule by gently pulling apart at the bottom tabs (See Figure C) and use it right away.
Step 3: Hold the bottom tab on the BETHKIS ampule with 1 hand (See Figure D). With your other hand, hold the top of the ampule and twist off the top of the ampule (See Figure D).
- Do not squeeze the ampule until you are ready to squeeze all the medicine into the Nebulizer Cup.
Step 4: Hold the Nebulizer Cup and twist off the Nebulizer Cup Top in a counter-clockwise direction (See Figure E). Set the Top aside on a clean, dry surface.
Step 5: Squeeze all of the medicine from the ampule into the Nebulizer Cup (See Figure F).
Step 6: Line up the semi-circle on the Nebulizer Cup Top with the Nebulizer Cup Outlet and twist on the Nebulizer Cup Top in a clock-wise direction until it is tight. (See Figure G).
Step 7: Push the mouthpiece straight onto the Nebulizer Cup Outlet (See Figure H).
Step 8: Firmly push the Inspiratory Valve Cap straight down onto the Nebulizer Cup Top (See Figure I). The Inspiratory Valve Cap should fit tightly.
Step 9: Connect 1 end of the tubing to the compressor air outlet. The tubing should fit tightly (See Figure J).
Step 10: Plug your compressor plug into an electrical outlet (See Figure K).
Step 11: Hold the Nebulizer Cup upright and firmly push the free end of the tubing straight up onto the Air Intake on the bottom of the Nebulizer Cup (See Figure L). Make sure to keep the Nebulizer Cup upright.
Giving your BETHKIS dose:
Step 12: Turn on the compressor (Figure M) and check the Mouthpiece. You should see a steady mist coming from the Mouthpiece (Figure N).
- If you do not see a steady mist coming from the mouthpiece, check all tubing connections and make sure that the compressor is working the right way.
Step 13: Sit or stand in a comfortable, upright position that will let you breathe normally. Place the Mouthpiece between your teeth and on top of your tongue and breathe normally only through your mouth (See Figure O).
- Nose clips may help you breathe only through your mouth and not through your nose.
Step 14: Keep breathing in your BETHKIS dose for at least 15 minutes. You will know that you have received your full dose of medicine when you hear a “spitting noise” coming from the Mouthpiece for at least 1 minute and the Nebulizer Cup is empty.
After your BETHKIS Dose:
Step 15: Clean and disinfect your nebulizer (see manufacturer's instructions).
