Important: How To Use This Information
This is a summary and does NOT have all possible information about this product. This information does not assure that this product is safe, effective, or appropriate for you.

Always ask your health care professional for complete information about this product and your specific health needs.
This medication is used when needed to treat the return of Parkinson's symptoms (known as OFF episodes) in people with Parkinson's disease who are treated with carbidopa/levodopa medicines. Parkinson's disease tends to worsen over time, and you may need extra levodopa from time to time to keep symptoms (such as shakiness, stiffness, difficulty moving) from returning. This medication does not replace your regular carbidopa/levodopa medicine. Keep taking your carbidopa/levodopa medicine regularly as directed by your doctor.
Parkinson's disease is thought to be caused by too little of a naturally occurring substance (dopamine) in the brain. Levodopa changes into dopamine in the brain, helping to control movement.
How To Use
Read the Patient Information Leaflet and Instructions for Use provided by your pharmacist before you start using levodopa inhalation powder and each time you get a refill. Learn how to use the inhaler properly. If you have any questions, ask your doctor or pharmacist.
Do not swallow the capsules. Use the special inhaler to inhale the powder in the capsules. Inhale this medication by mouth as directed by your doctor, when symptoms of an OFF period start. Each dose is 2 of the 42-milligram capsules. Make sure your hands are clean and dry before preparing your dose. Load one capsule in the inhaler and breathe out completely, holding the inhaler level and away from your mouth. While keeping the inhaler level, close your lips firmly around the mouthpiece and take a deep, comfortable breath. You should hear and feel the capsule "whirl" (spin) as you breathe in. Take the inhaler out of your mouth and hold your breath for 5 seconds, then breathe out. Remove the used capsule from the inhaler. Repeat with a second capsule to finish a full dose. Take used capsules out of the inhaler before storing the inhaler. Do not store unused capsules in the inhaler for a future dose.
The dosage is based on your medical condition and response to treatment. Do not use more than 1 dose per OFF period. Do not use more than 5 doses in one day.
Tell your doctor if your condition does not get better or if it gets worse.
Cough during or after using a dose may occur. Dizziness, lightheadedness, nausea, trouble sleeping, unusual dreams, stuffy/runny nose, sore throat, or fever may also occur. If any of these effects last or get worse, tell your doctor or pharmacist promptly.
This medication may cause saliva or nasal discharge to turn a dark color. This effect is harmless, but your clothes may be stained.
To reduce the risk of dizziness and lightheadedness, get up slowly when rising from a sitting or lying position.
Remember that your doctor has prescribed this medication because he or she has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.
Some people using this medication have fallen asleep suddenly during their usual daily activities (such as talking on the phone, driving). In some cases, sleep occurred without any feelings of drowsiness beforehand. This sleep effect may occur anytime during treatment with levodopa even if you have used this medication for a long time. If you experience increased sleepiness or fall asleep during the day, do not drive or do other possibly dangerous activities until you have discussed this effect with your doctor. Your risk of this sleep effect is increased by using alcohol or other medications that can make you drowsy. See also Precautions section.
Tell your doctor right away if you have any serious side effects, including:
- new/worsening movements you can't control/spasms
- greatly increased eye blinking/twitching
- vision changes (such as blurred vision, double vision)
