To use the Pressair®:

  • aclidinium comes in sealed pouch. Do not open the sealed pouch until you are ready to use a dose of aclidinium.
  • Once opened, remove the inhaler from the pouch.
  • Take the cap off the mouthpiece. Check the mouthpiece to make sure it is clear.
  • Press the green button all the way down and release it.
  • Check the control window to make sure your dose is ready for inhalation. Look if the colored control window changed from red to green.
  • To inhale aclidinium, breathe out fully and try to get as much air out of your lungs as possible. Put your lips tightly around the mouthpiece and breathe in quickly and deeply until you hear a "click" sound. Keep breathing in, even after you hear the "click" sound to be sure you get the full dose.
  • Do not hold the green button while you are breathing in.
  • Remove the inhaler from your mouth and hold your breath for as long as is comfortable, and then breathe out slowly through your nose.
  • Stop and check the colored control window if it has turned to red. This means you have inhaled full dose of aclidinium.
  • If the control window is still colored green, repeat the steps above. If you are unable to inhale correctly after several attempts, call your doctor.
  • Once the window has turned red, place the cap back by pressing it back into the mouthpiece.
  • If you want to clean the inhaler, wipe the mouthpiece with a dry tissue or towel. Do not use water to clean the inhaler, as this may damage the medicine.

Precautions While Using aclidinium

It is very important that your doctor check your progress closely while you are using aclidinium to see if it is working properly and to help reduce any unwanted effects.

Check with your doctor right away if you have any changes to your eyes, such as eye pain or discomfort, blurred vision, visual halos, or colored images with red eyes while you are using aclidinium. Your doctor may want your eyes to be checked by an eye doctor. These could be symptoms of acute narrow-angle glaucoma.

aclidinium may cause serious allergic reactions. These reactions can be life-threatening and require immediate medical attention. Call your doctor right away if you have a rash, itching, hives, hoarseness, trouble breathing, trouble swallowing, or any swelling of your hands, face, mouth, or throat while you are using aclidinium.

Call your doctor right away if you use other medicines for your lung condition and they do not seem to be working as well as usual. Do not change your doses or stop using your medicines before you talk to your doctor.

Do not take other medicines unless they have been discussed with your doctor. This includes prescription or nonprescription (over-the-counter [OTC]) medicines for appetite control, asthma, colds, cough, hay fever, or sinus problems, and herbal or vitamin supplements.
