Parkinson’s Medicine Side Effects

How To Take Entacapone

What are the most common side effects of Parkinson’s disease medications?
  • Before you start the treatment, read the manufacturer’s printed information leaflet from inside the pack and any additional information your doctor has given to you. These will give you more information about entacapone, and will also provide you with a full list of side-effects which you could experience from taking it.
  • Take the tablets exactly as your doctor tells you to. If you are prescribed Comtess®, take one 200 mg tablet at the same time as your co-careldopa or co-beneldopa tablet or capsule. If you are prescribed Stanek®, Stalevo® or Sastravi® tablets, these are available in different strengths. You will be prescribed the strength of tablet that best suits your condition. Your doctor will tell you how to take the tablets, and the directions will also be on the label of the pack to remind you about what the doctor said to you.
  • You can take entacapone either before or after meals.
  • When you first start taking entacapone, your doctor may need to adjust the doses of your other medicines. This is to help reduce any side-effects caused by these tablets increasing the effectiveness of your usual dose of levodopa.

Controlled Release Madopar And Sinemet

Controlled release preparations have the letters CR or HBS after the drug name.

These let the levodopa enter your body slowly instead of all at once. They can increase the time between doses.

They may be used when the dose of standard levodopa starts to wear off and the person taking it no longer feels the treatment is effective.

Controlled release options can sometimes reduce involuntary movements .

Keep A Medicine And Symptoms Diary

Keeping a diary is a helpful way of monitoring your condition and keeping track of your medicines. A diary can be a useful way of letting your doctor know what problems youre experiencing, any changes in your condition from day to day or over a period of time, and how well your medicine is controlling your symptoms. It can also help remind you of things you want to discuss during your appointment that you may otherwise forget. You can also use it to record any embarrassing issues that you want help with but find difficult to ask about. Examples of diaries:

Some Disadvantages Of Comt Inhibitors

These drugs can increase the side effects caused by levodopa, notably dyskinesias , nausea and vomiting.

If these side effects increase after starting the drug, people should raise the issue with their healthcare professional, as reducing the levodopa dose can often help.

COMT inhibtors will discolour urine making it a reddish-brown colour. Some people also experience diarrhoea which may occur some months after commencing the medication.

Be aware that other drugs for Parkinsons or other conditions can affect the action of COMT inhibitors. The combination of apomorphine and entacapone needs careful supervision.

How Is Parkinsons Treated In The Early Stages

Three main groups of medication are used to treat Parkinsons in the early stages:

  • Levodopa : is converted into dopamine in the brain.
  • Dopamine agonists: stimulate the nerve receptors responsible for the uptake of dopamine.
  • MAO-B inhibitors : block the breakdown of dopamine in the brain.

The medications are usually taken in tablet form. Some dopamine agonists are also available as patches.

In the early stages, some people with mild symptoms cope just fine without medication. If at some stage the symptoms become too much of a problem, levodopa and dopamine agonists are the main medication options. They work slightly differently to each other, and some products may cause side effects more often or have worse side effects than others. But both are very effective in the early stages of the illness. That helps many people with Parkinsons to live a fairly symptom-free life for at least a few years.

Why Is This Medication Prescribed

The combination of levodopa and carbidopa is used to treat the symptoms of Parkinson’s disease and Parkinson’s-like symptoms that may develop after encephalitis or injury to the nervous system caused by carbon monoxide poisoning or manganese poisoning. Parkinson’s symptoms, including tremors , stiffness, and slowness of movement, are caused by a lack of dopamine, a natural substance usually found in the brain. Levodopa is in a class of medications called central nervous system agents. It works by being converted to dopamine in the brain. Carbidopa is in a class of medications called decarboxylase inhibitors. It works by preventing levodopa from being broken down before it reaches the brain. This allows for a lower dose of levodopa, which causes less nausea and vomiting.

Stay Safe With Your Medicines

Read all labels carefully.

  • Tell all your health care providers about all the medicines and supplements you take.
  • Know all the medicines and foods youâre allergic to.
  • Review any side effects your medicines can cause. Most reactions will happen when you start taking something, but thatâs not always the case. Some reactions may be delayed or may happen when you add a drug to your treatment. Call your doctor right away about anything unusual.
  • Use one pharmacy if possible. Try to fill all your prescriptions at the same location, so the pharmacist can watch for drugs that might interact with each other.
  • You can use online tools to see if any of your medicines wonât work well together.

You have the right and responsibility to know what medications your doctor prescribes. The more you know about them and how they work, the easier it will be for you to control your symptoms. You and your doctor can work together to create and change a medication plan. Make sure that you understand and share the same treatment goals. Talk about what you should expect from medications so that you can know if your treatment plan is working.

What Are The Surgical Treatments For Parkinsons Disease

Most patients with Parkinsons disease can maintain a good quality of life with medications. However, as the disease worsens, medications may no longer be effective in some patients. In these patients, the effectiveness of medications becomes unpredictable reducing symptoms during on periods and no longer controlling symptoms during off periods, which usually occur when the medication is wearing off and just before the next dose is to be taken. Sometimes these variations can be managed with changes in medications. However, sometimes they cant. Based on the type and severity of your symptoms, the failure of adjustments in your medications, the decline in your quality of life and your overall health, your doctor may discuss some of the available surgical options.

Parkinsons And Urinary Problems

Just as your digestive tract may become weaker, so can the muscles of your urinary tract system.

Parkinsons disease and medications prescribed for treatment can cause your autonomic nervous system to stop functioning properly. When that happens, you may begin experiencing urinary incontinence or difficulty urinating.

What Other Information Should I Know

Keep all appointments with your doctor and the laboratory. Your doctor will order certain lab tests to check your response to levodopa and carbidopa.

Before having any laboratory test, tell your doctor and the laboratory personnel that you are taking levodopa and carbidopa.

Levodopa and carbidopa can lose its effect completely over time or only at certain times during the day. Call your doctor if your Parkinson’s disease symptoms worsen or vary in severity.

As your condition improves and it is easier for you to move, be careful not to overdo physical activities. Increase your activity gradually to avoid falls and injuries.

Levodopa and carbidopa can cause false results in urine tests for sugar and ketones .

What Causes Parkinsons Disease

Parkinsons disease occurs when nerve cells in an area of the brain called the substantia nigra become impaired or die. These cells normally produce dopamine, a chemical that helps the cells of the brain communicate . When these nerve cells become impaired or die, they produce less dopamine. Dopamine is especially important for the operation of another area of the brain called the basal ganglia. This area of the brain is responsible for organizing the brains commands for body movement. The loss of dopamine causes the movement symptoms seen in people with Parkinsons disease.

People with Parkinsons disease also lose another neurotransmitter called norepinephrine. This chemical is needed for proper functioning of the sympathetic nervous system. This system controls some of the bodys autonomic functions such as digestion, heart rate, blood pressure and breathing. Loss of norepinephrine causes some of the non-movement-related symptoms of Parkinsons disease.

Scientists arent sure what causes the neurons that produce these neurotransmitter chemicals to die.

How Do I Prevent Falls From Common Hazards

Are there any side-effects with Parkinsons disease medications? (Karen Blindauer, MD)
  • Floors: Remove all loose wires, cords, and throw rugs. Minimize clutter. Make sure rugs are anchored and smooth. Keep furniture in its usual place.
  • Bathroom: Install grab bars and non-skid tape in the tub or shower. Use non-skid bath mats on the floor or install wall-to-wall carpeting.
  • Lighting: Make sure halls, stairways, and entrances are well-lit. Install a night light in your bathroom or hallway and staircase. Turn lights on if you get up in the middle of the night. Make sure lamps or light switches are within reach of the bed if you have to get up during the night.
  • Kitchen: Install non-skid rubber mats near the sink and stove. Clean spills immediately.
  • Stairs: Make sure treads, rails, and rugs are secure. Install a rail on both sides of the stairs. If stairs are a threat, it might be helpful to arrange most of your activities on the lower level to reduce the number of times you must climb the stairs.
  • Entrances and doorways: Install metal handles on the walls adjacent to the doorknobs of all doors to make it more secure as you travel through the doorway.

Dopaminergic Features And Their Treatment

Patients with PD usually present with features indicative of degeneration of nigrostriatal pathways. A useful clinical definition for PD is asymmetric onset of an akinetic rigid syndrome with resting tremor and a good response to levodopa. When applied by neurologists with an interest in movement disorders, this definition has a pathological correlation exceeding 98%. When treatment is considered appropriate, and this is a topic discussed in detail below, a variety of options is available. The use of dopaminergic drugs improves motor function, significantly reduces both the morbidity and mortality of PD, and improves quality of life.

Levodopa remains the drug most commonly used in PD. It is very effective in improving bradykinesia and rigidity, and in practice remains the gold standard against which other drugs are judged. Some studies, predominantly in vitro, have suggested that levodopa may be toxic. However, such data are conflicting, and some laboratory studies have suggested a growth factor-like effect for levodopa. Overall, the pre-clinical evidence for levodopa toxicity is not convincing and there are no data to indicate that any toxic action is of clinical relevance.

General Advice On Taking Oral Antiparkinsonian Drugs

  • Drugs improve most patients quality of life and the activities of daily living, even though they cannot cure Parkinsons disease nor prevent disease progression.
  • Long-term use of antiparkinsonian drugs is usually necessary and abrupt withdrawal of the medication without medical supervision should be avoided.
  • Good self-care can benefit patients enormously. Self-care includes things that you do to maintain good physical and mental health, prevent illness or accidents, and effectively deal with minor ailments and long-term conditions like having a balanced diet with regular exercise and adequate rest.
  • Be familiar with the name and dosage of the antiparkinsonian drugs you are taking. Be cautious of their possible side effects.

Moral Competence And Personality

These are the issues with the most confounding ethical impact. While hypomania subsides and depression may respond to treatment, rarely measurements are taken to exclude less obvious changes in behavior and personality. Fundamental changes in personality have been relatively seldom been studied although basic research documents the role of the STN in decision making . Relatives however report reckless and risk seeking behavior that lasts well beyond the postoperative phase. Again, these types of behavioral change may occur gradually in the natural course of the disease or as side effect of drugsbut the sudden and seemingly irreversible alteration of personally after DBS comes as a shock for families. Probably the most profound, albeit at first sight easily overlooked effects are changes in moral competences of the patients. Such changes may result in taking risks for oneself and ignoring the rights of others, exemplified by car accidents or marital conflicts . Seminars for management of such conflicts after DBS are therefore already offered with patients and spouses reporting their experiences.

Dopamine Agonist Withdrawal Syndrome

Parkinsonâs disease

If you suddenly stop taking dopamine agonists, this can lead to dopamine agonist withdrawal syndrome, which can cause symptoms such as depression, anxiety or pain.

Any withdrawal from Parkinsons drugs needs to be done in a tapered way, under the supervision of a health professional.

Deep Brain Stimulation For Parkinsons Disease

Deep brain stimulation is a surgical intervention used to treat movement disorders such as Parkinsons disease when the regimen of existing medications and the various rehabilitation strategies become less effective in managing symptoms. This surgical procedure received approval from the Food and Drug Administration to treat tremor in Parkinsons disease in July 1997 and for advanced motor symptoms of Parkinsons disease in January 2002.

For people with Parkinsons disease, deep brain stimulation surgery may be helpful if the individual is experiencing motor fluctuations including dyskinesias or off episodes.

The subthalamic nucleus and the globus pallidus are two locations in the brain that are targeted in the DBS procedure for Parkinsons. Certain symptoms of Parkinsons disease can be reduced when these two areas are turned off by the stimulator. These include tremor, rigidity, slowness of movement, difficulty walking, and freezing, as well as extra movements or dyskinesia that are medication side effects. The amount of daily on time during which the Parkinsons symptoms are better controlled can be increased as well.

The best marker of whether or not people with Parkinsons disease will benefit from DBS is how well they respond to levodopa, an active ingredient in the drug SinemetTM or carbidopa/levodopa. Patients who benefit most from surgery have had a good response to levodopa. For many, this good response becomes less and less as the disease progresses.
