1. What Inbrija is and what it is used for

The active substance in Inbrija is levodopa. Inbrija is a medicine used by inhalation for treating the worsening of your symptoms during the “off periods” of Parkinson’s disease.

Parkinson’s disease affects your movement and it is treated with a medicine that you take regularly. During off periods your usual medicine does not control the condition well enough and movement is likely to be more difficult.

You should continue taking your main medicine for Parkinson’s disease and use Inbrija to control worsening of symptoms (such as inability to move) during off periods.

2. What you need to know before you use Inbrija
Do not use Inbrija:
  • if you are allergic to levodopa or any of the other ingredients of this medicine (listed in section 6).
  • if you get blurred vision, red eyes, severe eye and head pain, halos around lights, pupils of your eyes that are larger than normal size and feel sick. If you have any of these symptoms, you may have a eye condition called narrow angle glaucoma, which occurs suddenly: do not take Inbrija and get urgent medical attention.
  • if you have a rare tumour of the adrenal gland called phaeochromocytoma.
  • if you are taking certain antidepressant medicines called non-selective MAO inhibitors (e.g. isocarboxazid and phenelzine). You must stop taking these medicines at least 14 days before starting treatment with Inbrija. See also under “Other medicines and Inbrija”.
  • if you have previously suffered from neuroleptic malignant syndrome, a life-threatening reaction to certain medicines used to treat severe mental disorders or if you have suffered from non-traumatic rhabdomyolysis, a rare muscle disorder in which damaged muscle breaks down rapidly.

Warnings and precautions

Get urgent medical help if you have tremors, agitation, confusion, fever, rapid pulse, or dizziness and fainting upon standing up, or you notice that your muscles get very rigid or jerk violently. These may be symptoms of “withdrawal-emergent hyperpyrexia”. For more information see section 4.

Talk to your doctor or pharmacist before using Inbrija if you have, or have ever had, or you develop:

  • asthma, breathing difficulties like chronic obstructive pulmonary disease (COPD) or other long-term lung diseases or breathing problems;
  • any form of severe mental disorder like psychosis;
  • a heart attack, or heart beat problems. Your doctor will monitor you closely during start of treatment;
  • an ulcer in your stomach or intestines;

This leaflet was last revised in November 2025.

Instructions for use:
Read these instructions before you start using Inbrija.

Overview

  • Make sure your hands are clean and dry when using the inhaler and capsules.
  • Only remove the capsules from the blister immediately before use.
  • A complete dose is 2 capsules used one after the other.
  • Load 1 capsule into the Inbrija inhaler, close your lips firmly around the mouthpiece, then breathe in (inhale) and hold that breath for 5 seconds. You should hear the capsule “whirl”. Then, remove the used capsule and load a second capsule into the inhaler. Close your lips firmly around the mouthpiece and breathe in, again holding your breath for 5 seconds.
  • You should inhale the contents of the second capsule within 10 minutes of the first one.
  • Do not load 2 capsules at the same time.
  • Dispose of all used capsules immediately after use.
  • Dispose of the inhaler after you are finished all of the capsules in the carton.

Prepare your dose

Step 1: Gather supplies

  • Find a clean and dry surface.
  • Make sure your hands are clean and dry.
  • Get inhaler and strip of capsules.
  • Tear off package of 2 capsules.

A full dose is 2 capsules.

Step 2: Remove blue cap from inhaler

  • Pull the cap straight off.
  • Place the cap to the side. You will need it later to store the inhaler.

Step 3: Twist and pull off white mouthpiece

  • Twist and pull off the mouthpiece to separate it from the handle.
  • Place the mouthpiece and inhaler on a clean and dry surface.

Step 4: Remove 1 capsule from package

  • Carefully peel back the foil and take out 1 capsule.
  • Only remove 1 capsule at a time, and just before use.
  • Do not use any capsule that looks crushed, damaged or wet. Dispose of it and get a new capsule.

Step 5: Load capsule

  • Hold the inhaler upright using the handle.
  • Drop 1 capsule into the opening of the capsule chamber.
  • Do not load 2 capsules at the same time.

Step 6: Attach white mouthpiece

Align arrows on mouthpiece and handle

  • Line up the white arrows on the handle and mouthpiece.

Compress mouthpiece only once

  • Firmly push the mouthpiece and handle together until you hear a click. This punctures the capsule.
  • Do not push the handle and mouthpiece together more than once.

Release mouthpiece

  • Release the mouthpiece. The mouthpiece will spring back and stay attached.

Your inhaler is now ready to use.

Do not push the handle and mouthpiece together more than once. This may damage the capsule, and you may not get your full dose. If this happens start again at Step 4 using a new capsule.

Make sure the mouthpiece is securely attached and will not fall off before moving to Step 7.

Take your dose

Step 7: Hold inhaler away and breathe out

  • Stand or sit with your head and chest upright.
  • Hold the inhaler level and away from your mouth.
  • Breathe out completely.
  • Do not breathe into mouthpiece.

Step 8: Breathe in deeply to inhale powder

  • While keeping the inhaler level, close your lips firmly around the mouthpiece.

Take in a deep, comfortable breath until your lungs feel full. This normally takes several seconds.

As you breathe in, you will hear and feel the capsule “whirl” (spin). The whirl means the inhaler is working and you are getting your medicine.

If you cough or stop your dose, start again from the beginning of Step 7 using the same capsule.

Important: If you did not hear or feel the capsule “whirl” while inhaling you may need to take a deeper, longer breath or may need to clean the mouthpiece (Do not rinse the mouthpiece or get the inhaler wet). Refer to Step 13 – Clean Mouthpiece. Start again from the beginning of Step 7 using the same capsule.

Step 9: Hold breath for 5 seconds, then breathe out

  • Take the inhaler out of your mouth and hold your breath for 5 seconds.
  • Then breathe out.

Step 10: Remove capsule from inhaler

Twist and pull off the mouthpiece

  • Twist and pull off the mouthpiece.

Remove used capsule

  • Take out the used capsule.

Step 11: Dose with 2nd capsule

  • Repeat Steps 4 to 10 with the second capsule to finish the full dose.
  • You should inhale the contents of the second capsule within 10 minutes of the first one.

Dispose and store

Step 12: Dispose of used capsules

  • Dispose of used capsules in accordance with local requirements.

Step 13: Clean Mouthpiece

It is normal for some powder to remain in or on the inhaler. To avoid powder buildup, clean the powder off of the mouthpiece holes using a circular motion with a new dry cotton swab as needed.

Clean holes from the top end of mouthpiece

  • Clean the holes from the top end of the mouthpiece.

Clean holes from bottom end of mouthpiece

  • Clean the holes from the bottom end of the mouthpiece.

You can also use a dry tissue to wipe the outside of the mouthpiece, as needed.

Do not clean any other parts of the inhaler.

Do not rinse the mouthpiece or get the inhaler wet.

Step 14: Store inhaler

Make sure there are no capsules in the inhaler

  • Make sure there are no capsules in the inhaler before you store it.

Attach mouthpiece

  • Attach the mouthpiece to the handle by pushing until you hear a click.

Attach cap

  • Attach the cap over the mouthpiece.

Ready for storage

  • Your inhaler is now ready to store.

Cleaning the inhaler

  • It is normal for some powder to remain in or on the inhaler.
  • To avoid powder buildup, clean the powder off of the mouthpiece holes using a circular motion with a new dry cotton swab as needed.
