Finding The Right Medication
Finding the right medication to treat your Parkinsons symptoms is a process that takes time and effort from you and your doctor. Parkinsons medications work in different ways. Many are pills that you swallow, but some can be given through skin patches or intestinal infusions. It can sometimes feel like trial and error to figure out the best medication, dose and schedule to treat your symptoms. Over time, as symptoms progress or complications arise, your doctor may adjust your medications. This might mean changing your dose or how often you take a drug, or adding or switching medications. Staying in tune with your symptoms and which are most bothersome, and keeping track of how well medication is or is not working can help direct adjustments to your treatment regimen.
Here we describe the different categories of Parkinsons medications how they work, their potential benefits and common side effects. We also give examples and highlight therapies that have been approved in the last few years with an asterisk.

How Do Anticholinergics Work
The motor symptoms of PD are caused by the reduction in dopamine. This is a neurotransmitter that sends signals in the brain to produce smooth, purposeful movement. As PD damages and destroys the nerve cells that make dopamine, the motor symptoms of PD appear.1,2
The primary treatments for PD directly affect dopamine. However, anticholinergics work in a different way to treat the symptoms of PD. They block the action of acetylcholine. This is another neurotransmitter involved in messages from the brain to the muscles. Anticholinergics work on correcting an imbalance between acetylcholine and dopamine in an area of the brain. Anticholinergics are often used in along with other treatments for PD.1,2

Sinemet And Other Medications
Below are lists of medications that can interact with Sinemet. These lists dont contain all drugs that may interact with Sinemet.
Before taking Sinemet, talk with your doctor and pharmacist. Tell them about all prescription, over-the-counter, and other drugs you take. Also tell them about any vitamins, herbs, and supplements you use. Sharing this information can help you avoid potential interactions.
If you have questions about drug interactions that may affect you, ask your doctor or pharmacist.
Sinemet and blood pressure medications
If youre taking medication for high blood pressure, that medication works to decrease your blood pressure. Sinemet may also decrease your blood pressure. Because both medications can have this effect, taking them together may increase your risk of orthostatic hypotension .
With OH, you have low blood pressure thats caused by standing up. Symptoms can include dizziness, blurry vision, or fainting.
Examples of blood pressure medications include:
If youre currently taking a blood pressure medication, your doctor may decrease your dosage of the that medication when you start taking Sinemet. This can help prevent OH.
If you have symptoms of OH while youre taking Sinemet and a blood pressure medication, talk with your doctor. They may decrease your dosage of the blood pressure medication.
Sinemet and MAOIs
Examples of nonselective MAOIs include:
- tranylcypromine

How Does This Condition Affect My Body
Parkinsons disease causes a specific area of your brain, the basal ganglia, to deteriorate. As this area deteriorates, you lose the abilities those areas once controlled. Researchers have uncovered that Parkinsons disease causes a major shift in your brain chemistry.
Under normal circumstances, your brain uses chemicals known as neurotransmitters to control how your brain cells communicate with each other. When you have Parkinsons disease, you dont have enough dopamine, one of the most important neurotransmitters.
When your brain sends activation signals that tell your muscles to move, it fine-tunes your movements using cells that require dopamine. Thats why lack of dopamine causes the slowed movements and tremors symptoms of Parkinson’s disease.
As Parkinson’s disease progresses, the symptoms expand and intensify. Later stages of the disease often affect how your brain functions, causing dementia-like symptoms and depression.
Sinemet With Other Drugs In Parkinsonism Treatment
For parkinsonism treatment, your doctor may also recommend that you take other medications along with your Sinemet.
For example, encephalitis is a possible cause of parkinsonism. And encephalitis may be treated with steroid medications such as prednisone. In addition, encephalitis is sometimes caused by a viral or bacterial infection. So, in people with this type of encephalitis, antibiotics or antiviral drugs may also be needed.
If you have questions about your parkinsonism treatment plan, talk with your doctor.

Speech And Occupational Therapy
Parkinsons disease can lead to slurred speech and difficulty swallowing. A speech and language therapist can provide muscle training techniques that may help overcome some of these problems.
An occupational therapist can help identify everyday tasks that can be challenging and work with the person to find practical solutions.
This may include new strategies for dressing, preparing meals, performing household chores, and shopping. Adaptations to the home environment can also make daily living easier.
For people with Parkinsons disease, deep brain stimulation may help manage:
- an electrode inside the part of the brain that controls movement
- a pacemaker-like device, or neurostimulator, under the skin in the upper chest
- a wire under the skin connecting the neurostimulator to the electrode
The neurostimulator sends electrical impulses along the wire and into the brain via the electrode. These impulses can prevent symptoms by interfering with the electrical signals that cause them.
There is a small risk of brain hemorrhage, infection, and headaches. Some people may see no improvement, or their symptoms may worsen. There may also be discomfort during stimulation.
Nevertheless, the AAN considers this treatment safe and effective for specific people and say any adverse effects are usually mild and reversible. Anyone considering this treatment should discuss the pros and cons with a healthcare professional.

Similarly one may ask, what happens when you stop taking carbidopa levodopa?
If you suddenly stop taking levodopa and carbidopa, you could develop a serious syndrome that causes fever, rigid muscles, unusual body movements, and confusion. Your doctor will probably decrease your dose gradually.
Similarly, can you just stop taking Sinemet? Do not stop taking Sinemet, or lower the dosage, without checking with your doctor. Your doctor may want you to gradually reduce the amount of Sinemet you are using before stopping completely. This may help reduce the possibility of withdrawal symptoms such as muscle stiffness, fever, and mental changes.
Keeping this in consideration, how many years can levodopa be effective?
For some people, wearing-off can begin within one to two years of starting levodopa therapy for others, levodopa may remain effective for five years or more.
What does carbidopa levodopa do to the body?
Carbidopa and levodopa is a combination medicine used to treat symptoms of Parkinsons disease, such as muscle stiffness, tremors, spasms, and poor muscle control. Parkinsons disease may be caused by low levels of a chemical called dopamine in the brain. Levodopa is converted to dopamine in the brain.

How Do I Get An Ongoing Supply And Can I Obtain Medication If I Go To Other Countries
You will need to discuss with the doctor or specialist who prescribes your medication how you can get an ongoing supply. This will vary according to where you live and the local services available, but usually arrangements are made for repeat prescriptions to be available at a pharmacy which is convenient for you.
Your doctor will also be able to tell you how many weeks supply you can have in advance. Again this varies from country to country so you will need to ask about this.
Not all medications are licensed in every country, and some are known by different names so it is a good idea to check the local names of medications you use before you travel if you are going abroad.
For information on availability at other international destinations it is best to check with your pharmacist, or local Parkinsons association. This website contains contact details for Our members, Other Parkinsons organisations.
As some medications are difficult to obtain in certain countries, and also in some cases, the quality may not always be of the highest standards, it is best to ensure that you take with you all the medications that you will need.
Carrying a few spare with you is always a good idea in case of any delays in your return. It is also advisable to carry a spare prescription with you just in case you do run out of medication while you are away.
For more information and useful suggestions on medication and travel, see Travel and relocating.
How Should I Take Sinemet
Take Sinemet exactly as prescribed by your doctor. Follow all directions on your prescription label and read all medication guides or instruction sheets. Your doctor may occasionally change your dose.
If you already take levodopa, you must stop taking it at least 12 hours before you start taking Sinemet.
Sinemet can be taken with or without food. Take your doses at regular intervals to keep a steady amount of the drug in your body at all times.
The tablet is sometimes broken in half to give the correct dose. Always swallow a whole or half tablet without chewing or crushing.
It may take up to several weeks of using Sinemet before your symptoms improve. For best results, keep using the medication as directed. Talk with your doctor if your symptoms do not improve after a few weeks of treatment. Also tell your doctor if the effects of this medication seem to wear off quickly in between doses.
If you use Sinemet long-term, you may need frequent medical tests at your doctors office.
This medicine can affect the results of certain medical tests. Tell any doctor who treats you that you are using Sinemet.
Do not stop using Sinemet suddenly, or you could have unpleasant withdrawal symptoms. Ask your doctor how to safely stop using this medicine.
Store at room temperature away from moisture, heat, and light.

How Long Does It Take For Levodopa To Work
We have often seen some terrible shaking in some old peoples and have witnessed their hand or arm tremor or even their head moving. Many people even name such problems as shaking disease. It can be even referred to be as one of the brain diseases as it begins mainly from the brain. It is common for almost every elderly people or even to some young people.
It is a very interesting fact that our nerve cell of our brain requires a certain chemical that is named by dopamine which helps to control the entire movement mechanism of our muscle. However, if the manufacturer cell of this dopamine that is present in the brain that is destroyed or damaged then the brain are not only able to work properly but also the muscles are unable to fetch the information that they expect. However, nobody knows that is why these cells of the brain gradually get damage or cannot make dopamine.
What Medications And Treatments Are Used
Medication treatments for Parkinsons disease fall into two categories: Direct treatments and symptom treatments. Direct treatments target Parkinsons itself. Symptom treatments only treat certain effects of the disease.
Medications
Medications that treat Parkinsons disease do so in multiple ways. Because of that, drugs that do one or more of the following are most likely:
Several medications treat specific symptoms of Parkinson’s disease. Symptoms treated often include the following:
- Erectile and sexual dysfunction.
- Hallucinations and other psychosis symptoms.
Deep brain stimulation
In years past, surgery was an option to intentionally damage and scar a part of your brain that was malfunctioning because of Parkinsons disease. Today, that same effect is possible using deep-brain stimulation, which uses an implanted device to deliver a mild electrical current to those same areas.
The major advantage is that deep-brain stimulation is reversible, while intentional scarring damage is not. This treatment approach is almost always an option in later stages of Parkinson’s disease when levodopa therapy becomes less effective, and in people who have tremor that doesnt seem to respond to the usual medications.
Experimental treatments
Researchers are exploring other possible treatments that could help with Parkinsons disease. While these arent widely available, they do offer hope to people with this condition. Some of the experimental treatment approaches include:

Which Body Parts Do Parkinsons Tremors Affect
There are five main places youâll have Parkinsonâs tremors:
1. Hands. Parkinsonâs disease tremors often start in the fingers or hands with whatâs called a pill-rolling motion. Imagine holding a pill between your thumb and index finger and rolling it back and forth.
2. Foot. A Parkinsonâs foot tremor is more likely to happen while youâre sitting or lying down with your feet at rest. If the tremor moves into your thigh muscles. It could look like your whole leg is shaking.
Foot tremors disappear when you stand or walk because those are active movements. A foot or leg tremor while youâre standing may be another condition.
3. Jaw. This is common in people with Parkinsonâs. It may look like youâre shivering. It can become bothersome if the tremor makes your teeth chatter. If you wear dentures, it could make them shift or fall out.
Chewing eases the tremor, so gum might help.
4. Tongue. Itâs rare, but a tongue tremor can cause your entire head to shake.
5. Internal. Some people with Parkinsonâs say they can feel a shaking sensation in their chest or abdomen. But canât be seen from the outside.
Dealing With Side Effects Of Parkinsons Drugs
Its important to speak to your specialist or pharmacist if you notice anything unusual.
Changing or adding to your medication might help, and your specialist will be able to look into this.
For many people with advanced Parkinsons, medication may start to be reduced if side effects outweigh the benefits of taking medication.
But if some of the medication is reduced, you may find you get the benefits of the remaining ones, rather than the side effects.
If you experience side effects from your Parkinsons medication, you shouldnt stop taking it without guidance from your specialist.

What Medications Are Used To Treat Parkinson’s Symptoms
Since many of the motor symptoms of Parkinsons are the result of a lack of dopamine in the brain, most drugs used to treat Parkinsons are aimed at temporarily replenishing or imitating dopamine. The following list is a guide to medications approved by Health Canada to treat symptoms of Parkinsons1. Speak to your doctor for detailed information regarding effectiveness and side effects of a particular drug.
Levodopa
- Converted into dopamine in the brain and stored in nerve cells to replace depleted dopamine
- Combined with another drug, carbidopa or benzerazide, allows more levodopa to get to the brain and reduces side effects
- Helps improve muscle rigidity and movement
- Side effects include dyskinesias
- Over years of use, may be associated with wearing off
Dopamine Agonists
- Mimics or imitates action of dopamine
- Can be used as initial treatment or with levodopa in advanced stages
- Side effects include sleepiness, hallucinations, leg swelling and obsessions with food, sex and activities such as shopping, gambling and Internet use Amantadine
- Enhances dopamine release and blocks glutamate, a brain transmitter
- Used to treat early symptoms
- Can reduce dyskinesias and improve wearing off
Dopamine Agonist
COMT Inhibitors
Delayed Administration And Contraindicated Drugs Place Hospitalized Parkinsons Disease Patients At Risk
Problem: One-third of all patients with Parkinsons disease visit an emergency department or hospital each year, making it a surprisingly common occurrence.1 The disease affects about 1 million people and is currently the fourteenth leading cause of death in the US. Hospitalization can be risky for patients with Parkinsons disease when viewed from the perspective of pharmacological management.
Patients with Parkinsons disease require strict adherence to an individualized, timed medication regimen of antiparkinsonian agents. Dosing intervals are specific to each individual patient because of the complexity of the disease. It is not unusual for patients being treated with carbidopa/levodopa to require a dose every 1 to 2 hours. When medications are not administered on time, according to the patients unique schedule, patients may experience an immediate increase in symptoms.2,3 Delaying medications by more than 1 hour, for example, can cause patients with Parkinsons disease to experience worsening tremors, increased rigidity, loss of balance, confusion, agitation, and difficulty communicating.2 Studies show that three out of four hospitalized patients with Parkinsons disease do not receive their medications on time, or have had doses entirely omitted.4 According to the National Parkinson Foundation, 70% of neurologists report that their patients do not get the medications they need when hospitalized.2

When Should I Start Taking Medication
If you have been diagnosed with Parkinsons, you may be wondering when you should start treatment and with what medication. There is no single strategy that applies to everyone. The timing will differ from person to person. It depends on a variety of factors, such as:
- the nature of your symptom
- your overall physical health
- whether you experience balance problems with walking
- changes in intellectual abilities, and
- your own attitude toward taking medication
When to start taking medication can be decided in consultation with your neurologist or movement disorder specialist. The decision to delay taking medication requires close monitoring and evaluation for risks of falls and injuries, especially if you are older. The older you are, the more you are at risk for a fall, and Parkinsons medication, when used appropriately, may reduce this risk.
Sinemet And Herbs And Supplements
Iron supplements may decrease the amount of levodopa that your body absorbs. So taking your dose of Sinemet with a multivitamin or supplement that contains iron may cause your dose of Sinemet to be less effective than usual. This means the drug may not reduce your symptoms as well as it normally would.
If you may need to take a multivitamin or supplement that contains iron while youre taking Sinemet, talk with your doctor about the best time to take each medication. This will help make sure that your body will absorb all of your supplement and medication.
