When This Medicine Should Not Be Used:

How to Use This Medicine:

Powder Under Pressure

  • Your doctor will tell you how much medicine to use. Do not use more than directed.
  • You will use the medicine with an inhaler device called Pressair®. The inhaler holds the powder medicine. Your doctor will show you how to use your inhaler. Make sure you understand all instructions.
  • Read and follow the patient instructions that come with this medicine. Talk to your doctor or pharmacist if you have any questions.
  • After you use a dose, check the colored control window to make sure it has changed back to red. If the control window is still green, you did not get the full dose. Try to use another dose. If you cannot get the full dose of medicine after you have tried several times, call your doctor.
  • Do not use water to clean your inhaler. This will damage the medicine.
  • Missed dose: Skip the missed dose and take your next dose at the regular time. Do not use 2 doses to make up for a missed dose.
  • Keep the medicine in the foil pouch until you are ready to use it. Store at room temperature, away from heat and direct light. Do not freeze.
  • Ask your pharmacist, doctor, or health caregiver about the best way to dispose of the used medicine container and any leftover medicine. You will also need to throw away old medicine after the expiration date has passed. Throw away the inhaler 45 days after you open the pouch, when there is a "0" with a red background on the dose counter, or when the device locks and you cannot press the green button.

Drugs and Foods to Avoid:

Ask your doctor or pharmacist before using any other medicine, including over-the-counter medicines, vitamins, and herbal products.
