Managing Wearing Off And Motor Fluctuations
If you think you are starting to experience wearing off or motor fluctuations, you should discuss this with your doctor promptly so that your medication can be adjusted to minimise your symptoms. Tell him or her how long your medication is lasting and what happens when it wears off. Remember to tell them about motor and non-motor symptoms.
The Latest Treatment For Parkinsons Disease
Inbrija is the latest treatment for Parkinson’s disease. It was approved by the Food and Drug Administration in late 2018 after two decades of research and development. Inbrija is a new form of levodopa that allows systemic delivery of the medication through inhalation, allowing higher doses of medication to enter the bloodstream.
This new drug from Acorda Therapeutics will treat the intermittent symptoms of OFF episodes on demand and comes in the form of a powder capsule and inhaler. Inbrija is the first and only inhaled levodopa medication to be approved for Parkinsons disease by the FDA. It is available by prescription through your doctor.
The Michael J. Fox Foundation helped to fund the early development of this new treatment for Parkinson’s disease due to the impact OFF periods have on patients’ lives.
What Is The On/off Phenomenon In Parkinsons
The ON/OFF phenomenon in PD happens when someone experiences flares of symptoms between regularly scheduled doses of levodopa.
During an ON episode, the levodopa is working well and symptoms improve. During an OFF episode, the levodopa isnt working and symptoms return or get worse.
A 2018 review found that 25 to 50 percent of people with PD developed OFF episodes within 2 years of beginning treatment with levodopa. Within 10 years of starting treatment, most people with PD had OFF episodes.
OFF episodes can affect different people in different ways. They may follow a predictable pattern or occur unpredictably. They may set in suddenly or gradually.

What Are Off Periods
These off periods are a time when dopamine is going low in the brain, and when medicine usually levodopa, which is the gold standard oral pill is wearing off or not kicking in when it should be, Dr. Robert Hauser, director of the Parkinsons & Movement Disorder Center and a professor in the college of medicine neurology at University of South Florida, told Healthline.
Symptoms such as the loss of motor function can return during off periods. This can be dangerous, particularly if an off period strikes when a person is walking up the steps to their front door or is in a similar situation.
For those who are newly-diagnosed , off periods can present a major obstacle to overcome if they arent aware of the risks and the need to maintain a strict medication schedule.
Will New Treatments Really Help
According to multiple clinical studies, treatment with Inbrija led to significant improvement in motor function, with an onset of 10 minutes. A review of 900 patients showed a reduction in the Unified Parkinson’s Disease Rating Scale, 30 minutes post-dose, after 12 weeks of treatment. Overall, 75% of patients who took Inbrija experienced a decline of daily OFF times.
According to Robert A. Hauser, MD, professor of neurology and director of the Parkinsons Disease and Movement Disorders Center at the University of South Florida:
Inbrija helps address a significant unmet need for people with Parkinsons, and we look forward to adding this new treatment option to our armamentarium.

Change The Type Of Carbidopa/levodopa
The type of carbidopa/levodopa youre taking may be changed. Your doctor may change the form of therapy youre receiving. Some forms of carbidopa/levodopa are extended-release formulations that release the medication steadily for a longer period of time.
There are also formulations that are available as a tablet that dissolves in your mouth or a suspension that is delivered directly into your small intestine via a tube.
The Bottom Line On On/off Periods With Parkinsons Meds
Managing the cycling between on and off periods with Parkinsons medications can be incredibly frustrating, but luckily, there are a number of effective ways to help reduce the peaks and valleys of motor symptoms.
Scientists are still exploring new and improved ways to help combat off periods with Parkinsons drugs, according to the Michael J. Fox Foundation for Parkinsons Research. You may even consider participating in one of these clinical trials, which you can learn more about with the Michael J. Fox Foundations clinical trial matching tool.
Even more exciting is the fact that researchers are also working diligently to try to improve Parkinsons treatments in generalreally looking into the crux of the disease to try to slow its progression overall, which would in turn help with this on-off period struggle, says Dr. Hui.
There are a number of clinical trials going on, so I think we should also stay tuned for development of to slow progression of disease, she says.

Making The Most Of On Time
If you start to experience your medication wearing off, its important that your drug regime is managed so you can make the most of your on time.
This becomes more complicated if you also begin to have involuntary movements. You might have to decide on a compromise between more on time with involuntary movements, or more off time with other Parkinsons symptoms.
Many people tend to prefer more on time, even with the dyskinesia, but everyone is different and you should discuss your options with your specialist or Parkinsons nurse.
Parkinsons Disease Off Episodes: What Are Offs
Parkinsons disease OFF episodes refers to periods of the day when Parkinsons medication does not work well, causing the worsening of Parkinsonian symptoms. Typically, patients have higher occurrences of OFFs in the morning following a treatment-free period overnight. The medical term for this is morning akinesia.
OFF episodes are part of the Parkinsons disease ON/OFF phenomenon that affects patients in the late stages of Parkinsons. This happens when patients have been taking levodopa for 3-5 years, and the medication stops working as well as it did.
Characteristics of OFF episodes include motor fluctuations such as:
- Stiffness
- Frozen gait
- Difficulty speaking and/or slurred speech
These symptoms are caused by the Parkinsons disease medication wearing off, usually around 3 hours after a dose or overnight. By contrast, ON periods can feel like someone has turned on a light. You may suddenly feel more energetic and able to move around freely. ON periods are when you feel at your most capable because your symptoms are controlled.
Unless your doctor makes changes to your medication, you will experience more OFF episodes than ON episodes between doses. Thankfully, there are various ways to manage Parkinsons disease OFF episodes when your Parkinsons medication is not working.

Exploring The Clinical Burden Of Off Periods In Parkinson Disease
Supplements and Featured Publications
ABSTRACT
Parkinson disease, the second-most-common neurodegenerative disorder, affects approximately 1 million individuals in the United States, and this number is projected to increase to 1.2 million by 2030. Characterized pathologically by degeneration of dopaminergic neurons, with widespread pathology in nondopaminergic systems, Parkinson disease leads to an array of motor and nonmotor symptoms that can significantly impact an affected individuals quality of life. Treatments for Parkinson disease typically focus on controlling the motor symptoms of the disease, including treating OFF periods when motor symptoms return. OFF periods can occur for many individuals with Parkinson disease, especially as the disease progresses, and can pose a substantial burden to those with the disease and their caregivers. Available treatments for OFF periods may help alleviate this burden.

Introduction
Diagnosis of PD usually occurs after age 50 years, and incidence rises with increasing age.1 In most populations, incidence of PD is twice as common in men as in women.1 In a population-based study conducted in Olmsted County, Minnesota, incidence was observed to increase over a 30-year period, particularly in men 70 years or older .4

When Is The Right Time To Start Medication
If your symptoms begin to have an effect on your day-to-day life, it might be time to start thinking about taking medication. This impact might be on how well you can move, or if you are able to get out and about socially.
If you become stiffer and are losing muscle, it can be difficult to turn back the clock. It may be easier if you are younger. But the risk of delaying treatment is that your condition will progress and your symptoms will get worse. Starting on medication can mean keeping things better for longer.
How Is The On/off Treated
Many of the strategies that can be used to treat Wearing-off effects can also be tried when someone is experiencing On/Off fluctuations, such as ensuring that you are taking your medication correctly, taking them with plenty of fluid and avoiding food at tablet time.
If your On/Off fluctuations are very bothersome, your doctor or PDNS may suggest a change in medication timing, dosage or type. Your doctor may advise you to try an enzyme inhibitor, or a long acting dopamine agonist to give smoother control of your symptoms, a concept devised to achieve a continuous delivery of dopamine to the brain. This continuous delivery of dopamine could also be achieved by the use of Apomorphine or Duodopa. For more information, speak to your doctor or PDNS, and see our information sheet: Medications and Parkinsons.

Why Might Someone Choose To Delay Taking Medication
If you have mild symptoms that are not impacting your day-to-day life, you may decide not to start treatment immediately.
Your specialist will consider the impact your symptoms are having on you age is less of a factor. For example, if your symptoms are impacting your daily life, your specialist may recommend you start medication. If you have very mild symptoms, you and your specialist may agree to wait until symptoms become more difficult.
Some people may not want to start taking medication because of the potential side effects. If you take levodopa for a long time, you might start to develop side effects, such as dyskinesia . But not everyone will experience severe problems and medication can usually be adjusted to minimise them.
Sometimes starting medication immediately can be helpful. If your specialist isnt sure whether you have Parkinsons, they may suggest medication to see how your symptoms respond. Drug treatments can then help determine a diagnosis.
Parkinsons symptoms can improve with medication. This is why its important that delaying treatment should be a joint decision made between you and your specialist.
The Reality Of Managing Symptoms
Dr. Benjamin Walter, of the Center for Neuro-Restoration at Cleveland Clinic, said that the average person isnt accustomed to the strict regimen of multiple medications a day thats part of everyday life for people with Parkinsons.
Most people feel burdened just taking an antibiotic, which can be difficult to remember. Now, imagine someone who has Parkinsons the minimal dosing is usually three times a day, Walter said.
He explained that the need to frequently take medication is because it usually only lasts in a persons bloodstream for 90 minutes.
Once the medication gets into the brain, its converted to dopamine and stored in dopamine neurons, which recycles and reuses that medication over and over until it is depleted. Now, its not uncommon to have patients on meds four or five times a day, he said.
Walter stressed that when discussing Parkinsons and off periods, no two people are the same.
Parkinsons is a highly variable disease. Some people will experience different motor symptoms and tremors than others.
For example, some people freeze when they walk, while others dont.
He said the off periods can be terrifying for many people and also cause a different symptom anxiety.
Walter said that its important for those taking care of a person with Parkinsons to understand how dangerous off periods can be.
He stressed the importance of making sure patients get their medications on schedule so that everything is kept in working order.

On/off Motor Fluctuation In Parkinsons Disease
The On/Off Phenomenon in Parkinsons Disease is related to fluctuating benefit of the medications used to treat PD.
Being On describes the time when the Person with Parkinsons feels that their medication is beneficial and that their symptoms are well controlled.
Being Off describes the time when the PwP feels that their medication is not working as well as usual, and some of their symptoms may have returned .
The On/Off phenomenon can best be described as a quick, unpredictable reappearance of PD symptoms. Likewise, switching from Off to On can occur just as suddenly. The speed of this shift can be so dramatic that some people have likened this effect to a light switch being turned on and off.
On/Off fluctuations are different from the phenomenon known as Freezing, which can also affect people who have had Parkinsons for some time. Freezing is the word used to describe the experience of stopping suddenly while walking or when trying to initiating walking, and people feel as though their feet are frozen or stuck to the ground. While Freezing episodes tend to last only a few seconds, an Off period can continue for minutes, or even hours.
How Else Can I Manage My Parkinson’s
Drug treatments are the main way to manage Parkinsons symptoms but other things can help.
Exercise is good for everyone and it is especially good for you if you have Parkinsons. It can be as important as medication in managing symptoms. The type of exercise you choose depends on the way Parkinsons affects you. But there is something for everyone.
Therapies can also help by focusing on a specific issue you may have. The three main types of therapy are physiotherapy, speech and language therapy and occupational therapy.

Why Do Motor Fluctuations Happen
As Parkinsons disease progresses, it is common for more dopamine-producing brain cells to die, causing the benefits from Parkinsons medications to not last as long as they did before. The brain eventually reaches a point where it stops producing dopamine in large amounts and therefore must rely on medicine to replace dopamine. Researchers think this happens for two reasons:
- As Parkinson’s progresses, cells become less able to store dopamine. When this occurs, the cells are unable to release dopamine without medications, such as levodopa. When the dose fades, 60-90 minutes after taking it, there is no more levodopa for the cells to use, resulting in lower dopamine levels and a worsening of symptoms .
- The cells in your brain become more sensitive to both higher and lower concentrations of levodopa. There is a higher likelihood of experiencing off times when levodopa levels are too low and a higher likelihood of experiencing dyskinesis when levodopa levels are too high.
As a result, your doctor may advise you increase your medication doses to achieve optimal control of motor symptoms, such as tremor, slowness and rigidity. The goal is to maximize symptom control without increasing side effects.
Common Drugs For Parkinson’s Disease
Levodopa and carbidopa . Levodopa is the most commonly prescribed medicine for Parkinsonâs. Itâs also the best at controlling the symptoms of the condition, particularly slow movements and stiff, rigid body parts.
Levodopa works when your brain cells change it into dopamine. Thatâs a chemical the brain uses to send signals that help you move your body. People with Parkinsonâs donât have enough dopamine in their brains to control their movements.
Sinemet is a mix of levodopa and another drug called carbidopa. Carbidopa makes the levodopa work better, so you can take less of it. That prevents many common side effects of levodopa, such as nausea, vomiting, and irregular heart rhythms.
Sinemet has the fewest short-term side effects, compared with other Parkinsonâs medications. But it does raise your odds for some long-term problems, such as involuntary movements. An inhalable powder form of levodopa and the tablet istradefylline have been approved for those experiencing OFF periods, OFF periods can happen when Parkinsonâs symptoms return during periods between scheduled doses of levodopa/carbidopa.
People who take levodopa for 3-5 years may eventually have restlessness, confusion, or unusual movements within a few hours of taking the medicine. Changes in the amount or timing of your dose will usually prevent these side effects.
Dopamine agonists. These drugs act like dopamine in the brain. They include pramipexole , rotigotine , and ropinirole , .
