This medicine is used to treat some of the symptoms of Parkinson’s disease which 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. Levo/Carbidopa Sandoz is most helpful in improving slow movement and muscle stiffness. It can also be helpful in treating shaking, difficulty in swallowing and drooling. It contains the active ingredients levodopa and carbidopa.

The symptoms of Parkinson’s disease are caused by a deficiency of dopamine, a natural substance produced by the brain. The brain requires dopamine to control muscle movements. When too little dopamine is produced in the brain, this results in slowness of movement. Levo/Carbidopa Sandoz contains two active ingredients, levodopa and carbidopa. Levodopa is a chemical closely related to dopamine which allows the body to make its own dopamine. Levodopa works by increasing the level of dopamine in the brain. Carbidopa makes sure that enough levodopa gets to the brain where it is needed.

Ask your doctor if you have any questions about why this medicine was prescribed for you. Your doctor may have prescribed it for another reason.

This medicine is only available with a doctor’s prescription.

Follow all directions given to you by your doctor or pharmacist carefully. They may differ from the information contained in this leaflet.

If you do not understand the instructions, ask your doctor or pharmacist for help.

How much to take

Ask your doctor or pharmacist if you are unsure of the correct dose for you. They will tell you exactly how much to take.

Follow the instructions they give you. If you take the wrong dose, Levo/Carbidopa Sandoz may not work as well and your problem may not improve.

The usual starting dose is half a tablet taken once or twice a day.

Your doctor will then adjust this dose depending on your condition, your response to this medicine and whether you are taking other medicines.

How to take it

Swallow the tablets with a full glass of water.

If you need to break Levo/Carbidopa Sandoz tablets, hold tablet with both hands and snap along break line.

How long to take Levo/Carbidopa Sandoz

Continue taking your medicine for as long as your doctor tells you. This medicine helps to control your condition, but does not cure it. It is important to keep taking your medicine even if you feel well.

Do not stop taking Levo/Carbidopa Sandoz, or change the amount you take, without checking with your doctor.

If you forget to take it

Take your dose as soon as you remember, and continue to take it as you would normally.

If it is almost time for your next dose, skip the dose you missed and take your next dose when you are meant to.

Do not take a double dose to make up for the dose that you missed. This may increase the chance of you getting an unwanted side effect.

If you are not sure what to do, ask your doctor or pharmacist.

If you have trouble remembering when to take your medicine, ask your pharmacist for some hints.

If you take too much (overdose)

Immediately telephone your doctor or the Poisons Information Centre (telephone Australia 13 11 26 or New Zealand 0800 POISON or 0800 764 766) for advice, or go to Accident and Emergency at the nearest hospital, if you think that you or anyone else may have taken too much Levo/Carbidopa Sandoz. Do this even if there are no signs of discomfort or poisoning. You may need urgent medical attention.


Things you must do

If you are about to be started on any new medicine, remind your doctor and pharmacist that you are taking Levo/Carbidopa Sandoz.

Tell any other doctors, dentists, and pharmacists who treat you that you are taking this medicine.

If you are going to have surgery, tell the surgeon or anaesthetist that you are taking this medicine. It may affect other medicines used during surgery.

If you become pregnant while taking this medicine, tell your doctor immediately.

Keep all of your doctor’s appointments so that your progress can be checked. Your doctor may do some tests from time to time to make sure the medicine is working and to prevent unwanted side effects.

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 Levo/Carbidopa Sandoz. 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.

If you experience times where Levo/Carbidopa Sandoz does not appear to be working as well as it did previously, tell your doctor. After taking this medicine for long periods of time, such as a year or more, some people suddenly lose the ability to move. This loss of movement may last from a few minutes to several hours. The person is then able to move as before. This condition may unexpectedly occur again and again. This problem is called the “on-off” effect. If this happens, your doctor may want to adjust your medication.

Things you must not do

Do not take Levo/Carbidopa Sandoz to treat any other complaints unless your doctor tells you to.

Do not give your medicine to anyone else, even if they have the same condition as you.

Do not stop taking your medicine or lower the dosage without checking with your doctor. Your doctor may want you to gradually reduce the amount you are taking before stopping completely. This may help reduce the possibility of withdrawal symptoms such as muscle stiffness, fever and mental changes.

Things to be careful of

Be careful driving or operating machinery until you know how Levo/Carbidopa Sandoz affects you. This medicine may cause dizziness, light-headedness, sudden onset of sleep or sleepiness. Very rarely it can cause extreme sleepiness and sudden onset of sleep in the middle of daytime activities, sometimes without warning. If you have any of these symptoms do not drive or do anything else that could be dangerous.

Be careful when drinking alcohol while you are taking this medicine. If you drink alcohol, dizziness or light-headedness may be worse.

Be careful not to eat a diet high in protein, as the amount of levodopa absorbed by the body may be reduced. Ask your doctor, pharmacist or dietician to check your diet.

If you are diabetic, check with your doctor or pharmacist before using urine sugar tests. Levo/Carbidopa Sandoz 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 Levo/Carbidopa Sandoz. Levo/Carbidopa Sandoz may affect the results of some tests.


Tell your doctor or pharmacist as soon as possible if you do not feel well while you are taking Levo/Carbidopa Sandoz. All medicines can have side effects. Sometimes they are serious, most of the time they are not. You may need medical attention if you get some of the side effects.

Ask your doctor or pharmacist to answer any questions you may have.

Tell your doctor or pharmacist if you notice any of the following and they worry you:
