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.Â;AnÂ;inhalable powder form of levodopa and the tablet istradefylline haveÂ;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.
Parkinsons Disease Medications To Avoid
Doctors avoid prescribing certain medications to Parkinsons disease patients for various reasons. Before deciding on a treatment plan, your doctor will assess your general health and consider any allergies or intolerances you might have. He or she will judge the best course of treatment based on your age, health status, medical history and existing medications. However, there are some drugs which most doctors will avoid. These include:
- Trihexyphenidyl and benztropine
People with Parkinsons disease have lower levels of dopamine. This is the chemical that, among other things, controls movement through electrical signals in the brain. Most medications, therefore, work to increase the levels of dopamine in the brain or mimic its effects so that patients experience fewer symptoms.
Unlike dopamine agonists, trihexyphenidyl and benztropine work by restoring the balance of dopamine and acetylcholine in the brain, which can be helpful for controlling tremors and involuntary movements. However, the long-term side-effects of these medications can be severe, particularly in older patients. Doctors rarely prescribe trihexyphenidyl and benztropine today, so these are Parkinson’s disease medications to avoid.
- Some cold remedies, such as decongestants
Some over-the-counter cold and flu medications can interact with Parkinsons disease medications. You should always check with your doctor or pharmacist about which OTC medications are safe to use.
- Anti-nausea medications
Visit Your Doctor More Often
The last and the most important advice we could give is to see your doctor often. Talk to your doctor about your conditions and figure out whether you need to make some changes in your diet to improve your symptoms.

Impact Of Diet On Parkinsons Medications
Taking certain foods may interfere with the efficacy of drugs used in Parkinsons disease. This is especially true for high-protein foods. Their consumption may affect the bodys ability to absorb levodopa, which is the most prescribed drug in Parkinsons disease. Its therefore good to take levodopa 30 60 minutes before eating the high-protein foods.
However, for some patients it causes nausea, and taking levodopa on an empty stomach might not be a good idea. In that case, taking levodopa with a small snack can enhance the absorption of the drug in the blood.
Remember: Your Doctor Knows Best
It is worth noting that, when it comes to treating Parkinson’s disease, your doctor always knows best. He or she may decide that the risk of side-effects is minimal or that the benefits of the medication will outweigh the negatives. If you disagree with your doctor’s decision, or you think there are Parkinson’s disease medications you’d like to avoid, don’t be afraid to get a second opinion. Parkinson’s is a progressive illness, so it’s important that you find a medical provider you can trust who will provide care and support for the long-haul.
Many patients have to try several Parkinson’s disease medications before they find a combination that works for them. However, your doctor will always start you on the medication with the least side-effects to see if it can control your Parkinson’s symptoms. Your medicine will be increased gradually over time, and other drug combinations will be tried if your symptoms progress or a medication stops working.

Activities Of Daily Living
There are many things a person does every day without even thinking about it such as bathing, brushing teeth, walking, turning in bed, signing checks, cutting food. When a person is diagnosed with Parkinson’s, it can eventually make all of these things more difficult. The following tips are meant to be helpful and raise awareness of adjusting to some of the difficulties with PD.
- Remove throw rugs and low-lying obstacles from pathways inside and outside your home.
- Use a cane when necessary.
- Avoid using stepladders or stools to reach high objects.
- Stop walking or sit down if you feel dizzy.
- Install handrails, especially along stairways.
- Slow down when you feel yourself in a hurry.
- Before rising from your bed or bath, pause for a moment in a sitting position.
- Stretch every day, especially before exercising.
- Exercise daily to build stamina.
- Warm baths and regular massage will help relax tired muscles.
- When your hands or feet get cold, wear gloves or warm socks.
- Don’t overdo physical activities; know your limits and stay within them.
Turning in bed
- Perform difficult tasks when you feel well and when your medication is working effectively.
- Relax. Sit down from time to time, relax your arms and shoulders, and take deep breaths.
- Get a regular massage.
- Ask your physical therapist or doctor to recommend a stretching and exercise program.
- Avoid caffeine and alcohol.
- Get plenty of rest.
Not All Drugs In These Classes Will Cause Symptoms Of Parkinsonism
Whats the difference?
Drug-induced parkinsonism usually develops on both sides of the body, while typical Parkinsons disease does not. Also, drug-induced parkinsonism usually does not progress like typical Parkinsons.
Unlike Parkinsons, drug-induced symptoms usually go away after the drug is stopped. It may take several months, though, for the symptoms to completely stop. If the symptoms remain, then it is possible that the drug may have unmaskedunderlying Parkinsons disease.
Who is at risk?
- Female: Women are twice as much at risk as men.
- Elderly: Older people are more likely to be on multiple medications or to have underlying Parkinsons disease.
- Those with a family history of Parkinsons disease.
- People with AIDS.

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.
Side Effects And Problems With Dopamine Agonists
Common side effects of dopamine agonists include:
- Nausea and vomiting
- Hallucinations or delusions and confusion
- Existing dyskinesias becoming more troublesome initially
If you are taking Cabergoline , Pergolide or Bromocriptine your neurologist or GP will have to arrange a chest CT scan or ultrasound of your heart yearly as over time these medications may effect heart or lung tissue.
This precaution does not apply to the other dopamine agonists available in Australia.

What To Do To Prevent Drug
The most common drugs linked to this condition are two used to treat schizophrenia or psychotic symptoms of dementia. They are haloperidol and perphenazine . Ask your doctor about parkinsonism if you or a loved one is concerned about a drug, especially these two drugs.
* Make sure you or a loved one are on the lowest effective dose.* If you already have Parkinsons disease, then tell your doctor if the symptoms appear to be getting worse since starting the drug.* Never stop taking a drug on your own. Talk to your doctor about any concerns.

Build A Unique Schedule
Establish a method and process to create and communicate the patients individualized medication schedule in order to control symptoms throughout the day. This requires clear communication between the patient-care unit and the pharmacy so patient-specific schedules are not overridden with standard dosing schedules.
Managing Medication Interactions And Side Effects
All prescribed medications can have potential side effects, including those used to treat Parkinsons. Some things you think are symptoms of Parkinsons may actually be side effects of medication. Some peoples side effects will have a big impact on their lives and have to be kept under control along with the symptoms.
Advantages Of Comt Inhibitors
When used with levodopa, COMT inhibitors can reduce the daily off time and increase the on time.
In many cases, the dose and frequency of levodopa can also be reduced.
The terms on/off or motor fluctuations refer to the period when people can no longer rely on the smooth and even symptom control that their drugs once gave them.

Other Medication Safety Concerns
Even with correct administration timing based on the patients home medication schedule, dosing errors have been reported with carbidopa/levodopa. The drug is available in many different strengths and forms, from an orally disintegrating tablet to extended- and immediate-release formulations. Levodopa, which converts to dopamine in the brain, can cause episodes of acute psychosis and dyskinesia when given in large doses, which can unnecessarily extend hospitalization. Also, patients may take different strengths of carbidopa/levodopa each time throughout the day, increasing the risk for errors. Documenting a complex scheduleeven if well understoodmay be difficult and even more challenging in some electronic health records.
Dysphagia is another manifestation of Parkinsons disease and can affect the patients ability to swallow medications. The symptoms include frequent coughing while drinking and taking medications and a gurgling voice.
Parkinsons Disease Medication And Alcohol
Little is known about the effects of alcohol on Parkinson’s disease itself. However, most doctors will tell you to avoid alcohol if you’re taking medications for PD. Here, we’ll look at some of the most common Parkinson’s disease medications and their interactions with alcohol.
Many Parkinsons disease medications contain levodopa, also known as L-dopa. Levodopa is essentially a chemical building block that your body converts into dopamine to control the symptoms of Parkinsons disease. Alcohol can increase the nervous system effects of levodopa such as drowsiness, dizziness and thinking impairment. Therefore, most guidelines state that you should avoid or limit alcohol consumption when taking this drug.
Dopamine agonists are often used to treat Parkinsons disease in place of levodopa. They can cause significant side-effects such as hallucinations, euphoria, psychosis and compulsive behavior. However, they do have the advantage of causing fewer long-term motor symptoms than other PD medications. Dopamine agonists are administered in small doses at first to check how you respond. Therefore a glass of wine is unlikely to affect you much. However, you should always consult your doctor before drinking alcohol with this medication.
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.
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 .
Do not let anyone else take your medication. Ask your pharmacist any questions you have about refilling your prescription
It is important for you to keep a written list of all of the prescription and nonprescription medicines you are taking, as well as any products such as vitamins, minerals, or other dietary supplements. You should bring this list with you each time you visit a doctor or if you are admitted to a hospital. It is also important information to carry with you in case of emergencies.

Combine Exercise With Diet
Dr. Gostkowski says if you want to feel your best, combine a healthy diet with exercise. Research has shown that regular exercise can improve PD symptoms.
Do exercise that raises your heart rate, Dr. Gostkowski says. Aim for about 30 minutes a day, five days a week. Dont worry about specific exercises. Do an activity you enjoy, as long as it gets your heart rate up. Try brisk walking or biking or more advanced exercise for veteran athletes. I recommend seeing an occupational therapist. They can tailor an exercise program to your needs.
Impulsive And Compulsive Behavior
Some people taking dopamine agonists may experience problems with impulsive or compulsive behaviours. For example an increased desire to gamble or engage in sexual activity. These behaviours often develop slowly so may not seem to be a problem immediately. It is important for both the person living with Parkinsons and their family to be aware of this side effect. If affected by this side effect, a reduction in dose or stopping the medication will stop the behaviour.
Help From Your Pharmacist
Your pharmacist is well placed to help you in your community when you need them. Its useful to go to the same pharmacist each time so they get to know you and your condition. If you have trouble taking your medication, your pharmacist can arrange an assessment to see how they can help. For example, they can offer large-print labels, non-click top bottles or a medication reminder chart.
They may also be able to put your medication into a blister pack. This means that each tablet has its own compartment linked to the correct time of day to remind you of your dose and when to take it.
A Critical Reappraisal Of The Worst Drugs In Parkinsons Disease
What are the worst drugs for Parkinsons disease patients?; Couldnt a simple list be assembled and disseminated to the Parkinson community?; Recently Ed Steinmetz, an experienced neurologist in Ft. Meyers, FL pointed out to me, a list approach published in the Public Citizen Newsletter . ;The approach was to list every drug associated with a single confirmed or unconfirmed symptom of Parkinsons disease or parkinsonism.; Parkinsons disease is defined as a neurodegenerative syndrome , whereas parkinsonism encompasses a wider net of drug induced and other potential causes. In parkinsonism symptoms are similar to Parkinsons disease, but patients do not have Parkinsons disease.; Patients and family members confronted with a simple drug list approach may falsely conclude that most medicines are bad for Parkinsons disease, and that any medicine may cause parkinsonism.; This concept is in general, incorrect. ;Although the approach is well-meaning, it is in need of a major revision, as Parkinsons disease and parkinsonism are too complex to summarize by simple lists. In this months column I will try to summarize the key information that patients and family members need to know about the worst pills, for Parkinsons disease and parkinsonism.

What Should I Know About Storage And Disposal Of This Medication
Keep this medication in the container it came in, tightly closed, and out of reach of children. Store it at room temperature and away from excess heat and moisture .
Store cassettes containing levodopa and carbidopa enteral suspension in the refrigerator in their original carton, protected from light. Do not freeze the suspension.
Unneeded medications should be disposed of in special ways to ensure that pets, children, and other people cannot consume them. However, you should not flush this medication down the toilet. Instead, the best way to dispose of your medication is through a medicine take-back program. Talk to your pharmacist or contact your local garbage/recycling department to learn about take-back programs in your community. See the FDA’s Safe Disposal of Medicines website for more information if you do not have access to a take-back program.
It is important to keep all medication out of sight and reach of children as many containers are not child-resistant and young children can open them easily. To protect young children from poisoning, always lock safety caps and immediately place the medication in a safe location â one that is up and away and out of their sight and reach.
