What Kinson is used for
Kinson is used to treat some of the symptoms of Parkinson's disease. This is a disease of the nervous system that mainly affects body movement. The three main symptoms are shaking (tremor), muscle stiffness and slow and unsteady movement.
People with Parkinson's disease often walk with a shuffle as they have difficulty in initiating movement. If untreated, Parkinson's disease can cause difficulty in performing normal daily activities.
Kinson is most helpful in improving slow movement and muscle stiffness. It can also be helpful in treating shaking, difficulty in swallowing, drooling and unstable posture.
The symptoms of Parkinson's disease are caused by a lack of dopamine, a naturally occurring chemical produced by certain brain cells. Dopamine sends messages in the part of the brain that controls muscle movement.
When too little dopamine is produced, slowness of movement results.
Kinson contains two active ingredients, levodopa and carbidopa. Levodopa is a chemical closely related to dopamine which allows the body to make its own dopamine. Carbidopa makes sure that enough levodopa gets to the brain where it is needed. In many patients, Kinson reduces some of the symptoms of Parkinson's disease.
Your doctor may have prescribed Kinson for another reason.
Ask your doctor if you have any questions about why Kinson has been prescribed for you. Kinson is available only with a doctor's prescription.
Kinson is available only with a doctor’s prescription.
Before you take Kinson
When you must not take it
Do not take Kinson if you are allergic to medicines containing levodopa, carbidopa or any of the ingredients listed at the end of this leaflet.
Some of the symptoms of an allergic reaction may include:
- wheezing or shortness of breath.
- skin rash, itching or hives;
- swelling of the face, lips or tongue which may cause difficulty in swallowing or breathing;
Do not take Kinson if you have:
- any unusual skin lumps or moles which have not been checked by your doctor

Do not take Kinson if you have a type of glaucoma called narrow-angle glaucoma.
Do not take Kinson if you are taking another medicine for depression called a monoamine oxidase inhibitor (MAOI), or you have previously taken a MAOI within the last 14 days. Some examples of MAOIs are phenelzine (Nardil) and tranylcypromine (Parnate).
Do not take Kinson if you are breastfeeding or plan to breastfeed. It has been shown that one of the active ingredients of Kinson passes into breast milk. Therefore, because of the potential harm to the baby, Kinson should not be used during breastfeeding.
Do not give Kinson to a child or teenager below 18 years old, unless advised by the child's doctor. The safety and effectiveness of Kinson in children and teenagers under 18 years old has not been established.

These behaviours are called impulse control disorders. Your doctor may need to review your treatments.

How to take Kinson
Follow all directions given to you by your doctor and pharmacist carefully. They may differ from the information contained in this leaflet.
If you do not understand the instructions on the pack, ask your doctor or pharmacist.
How much to take
Your doctor will tell you how many tablets to take each day. The dose varies considerably from patient to patient.
The usual starting dose is one Kinson 100/25 mg tablet three times a day. Your doctor may adjust this dose depending on how you respond to this medicine whether or not you are taking any other medicines.
How to take it
Swallow the tablets whole with a glass of water.
When to take it
Take your medicine at about the same time each day. Taking it at the same time each day will have the best effect. It will also help you remember when to take it.
How long to take it for
Keep taking Kinson for as long as your doctor recommends.
Kinson helps control some of the symptoms of Parkinson's disease, but does not cure your condition. It is important that you take Kinson every day on a regular basis.
Continue taking Kinson for as long as your doctor prescribed.
Do not stop taking Kinson, or lower the
sage, without checking with your doctor. Your doctor may want you to gradually reduce the amount of Kinson you are using before stopping completely. This may help reduce the possibility of withdrawal symptoms such as muscle stiffness, fever or mental changes.
If you forget to take it
If it is almost time for your next dose, skip the dose you missed and take your next dose when you are meant to.
Otherwise, take the missed dose as soon as you remember, and then go back to taking your tablets as you would normally.
Do not take a double dose to make up for the dose you missed.
If you are not sure what to do or have any questions, ask your doctor or pharmacist.
If you have trouble remembering to take your tablets, ask your pharmacist for some hints.
If you take too much (overdose)
Immediately telephone your doctor or the Poisons Information Centre (telephone 13 11 26) for advice, or go to Accident and Emergency at the nearest hospital, if you think you or anyone else may have taken too much Kinson. Do this even if there are no signs of discomfort or poisoning. You may need urgent medical attention.
While you are taking Kinson
Things you must do
If you feel light-headed, dizzy or faint get up slowly when getting out of bed or standing up. You may feel light-headed or dizzy while taking KINSON. This is because your blood pressure is falling suddenly. Standing up slowly, especially when you get up from bed or chairs, will help your body get used to the change in position and blood pressure. If this problem continues or gets worse, tell your doctor.
Before starting any new medicine, tell your doctor or pharmacist that you are taking Kinson.
Tell all the doctors, dentists and pharmacists who are treating you that you are taking Kinson.
If you become pregnant while taking Kinson, tell your doctor.
If you plan to have surgery, including dental surgery, that needs a general anaesthetic, tell your doctor or dentist that you are taking Kinson.
If you are diabetic, check with your doctor or pharmacist before using urine sugar tests. Kinson may cause false test results with some urine sugar tests.
If you need to have any other blood or urine tests, tell your doctor that you are taking Kinson. Kinson may affect the results of some tests.
Visit your doctor regularly so they can check on your progress. You may need to have tests to make sure that Kinson is not affecting your blood, liver, kidneys and heart.
Tell your doctor if you feel Kinson is not working as well as it did previously. In some people who have been taking Kinson for long periods of time, such as a year or more, sudden and unexpected losses of movement may occur. These may last from a few minutes to several hours. Afterwards, the person can move as before. This may unexpectedly occur again and again. This is called the "on-off" effect. If this happens, your doctor may want to adjust your medicine.
Things you must not do
Do not stop taking Kinson, or lower the dose, without checking with your doctor. Stopping Kinson suddenly may cause muscle stiffness, fever and mental changes. Your doctor may want you to gradually reduce the amount of Kinson you are taking before stopping completely.
Do not use Kinson to treat any other conditions unless your doctor tells you to.
Do not give Kinson to anyone else, even if they have the same condition as you.
Things to be careful of
Be careful when driving or operating machinery until you know how Kinson affects you. Kinson may cause dizziness or lightheadedness in some people. If this occurs, do not drive, operate machinery or do anything else that could be dangerous if you are dizzy or lightheaded. Drinking alcohol can makes dizziness and lightheadedness worse.
In addition, in very rare cases, Kinson may cause excessive sleepiness and sudden onset of sleep.
If you experience these effects, do not drive or operate machinery until these effects are resolved.
Be careful getting up from a sitting or lying position. Dizziness, lightheadedness or fainting may occur, especially when you get up quickly. This is because your blood pressure is suddenly falling. Getting up slowly may help. If this problem continues or gets worse, tell your doctor.
Be careful not to eat a diet high in protein. The amount of levodopa absorbed by your body may be reduced if your diet is high in protein. Ask your doctor, pharmacist or dietician to check your diet.
Tell your doctor or pharmacist as soon as possible if you do not feel well while you are taking Kinson.
