How should I use tobramycin?

Use tobramycin exactly as directed by your doctor. If you do not understand these instructions, ask your pharmacist, nurse, or doctor to explain them to you.

Tobramycin is inhaled into the lungs with the use of a nebulizer. Do not swallow the solution by mouth.

Wash your hands with soap and water before preparing each treatment.

To use tobramycin inhalation:

  • Set up the nebulizer as directed.
  • Open one ampule of tobramycin solution for inhalation and squeeze the contents of the ampule into the nebulizer cup. Replace the nebulizer top.
  • Turn on the compressor. Check for a steady mist from the mouthpiece. If there is no mist, check all tubing connections and make sure the compressor is working.
  • Sit or stand in a position that will allow you to breathe normally. Place the mouthpiece of the nebulizer between your teeth and above your tongue and breathe normally only through your mouth. A noseclip may help you to breathe only through your mouth during a treatment. Continue breathing through the mouthpiece until all of the medicine is gone and no more mist is being produced. You may hear a sputtering sound when the nebulizer cup is empty. The entire treatment should take approximately 15 minutes to complete.
  • If you are interrupted or need to cough or rest during a treatment, turn the compressor off to save the medication. Turn the compressor back on when you are ready to resume treatment.

To reduce the risk of illness, infection, or injury from contamination, you must thoroughly clean all parts of the nebulizer as directed after each treatment.

If you are using several respiratory medications, the recommended order is bronchodilator first, followed by chest physiotherapy, then other inhaled medications, followed by tobramycin.
