Co-careldopa för Parkinsons sjukdom

About co-careldopa

You will have been prescribed co-careldopa to relieve symptoms of Parkinsons sjukdom. In Parkinson's disease, a number of cells in a small part of the brain called the substantia nigra become damaged and die. These brain cells pass messages down nerves in the spinal cord by producing a chemical called dopamine, and it is these messages which control the muscles of the body. As the cells in the substantia nigra are damaged, the amount of dopamine that is produced is reduced. A combination of the reduction of cells and a low level of dopamine in the cells in this part of the brain, causes nerve messages to the muscles to become slowed and abnormal. This produces the main symptoms of Parkinson's disease, which are stiffness, shaking (tremor), and slowness of movement.

Co-careldopa contains two ingredients, levodopa and carbidopa. Once in the body, levodopa is converted into dopamine which helps to restore the level of dopamine in the damaged area of the brain. The carbidopa ingredient helps to prevent the levodopa from being broken down into dopamine in parts of the body other than the brain. This means more levodopa gets into the brain to be converted into dopamine, and it also helps to reduce side-effects.

Before taking co-careldopa

Some medicines are not suitable for people with certain conditions, and sometimes a medicine may only be used if extra care is taken. For these reasons, before you start taking co-careldopa it is important that your doctor knows:

• If you have lung disease or a problem with your breathing.

• If you have ever had a stomach ulcer.

• If you have heart or blood vessel problems.

• If you have a problem with raised pressure in your eye (glaucoma).

• If you have ever had a fit (seizure).

• If you have any problems with the way your liver works, or with the way your kidneys work.

• If you have a mental health problem.

• If you have ever had skin cancer.

• If you know you have any of the following: an overactive thyroid gland, Cushing's syndrome, diabetes, weakened bones (osteomalacia), or a growth on your adrenal glands, called phaeochromocytoma.

• Om du är gravid eller ammar.

• Om du tar några andra läkemedel. Detta inkluderar alla läkemedel du tar som finns att köpa utan recept, samt växtbaserade och komplementära läkemedel.

• Om du någonsin har haft en allergisk reaktion mot en medicin.

How to take co-careldopa

• 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 co-careldopa and will provide you with a full list of the side-effects which you may experience from taking it.

• Take co-careldopa exactly as your doctor tells you to. It is usual to take a dose several times each day. Your doctor will prescribe a dose that best suits you and will tell you how much to take and when to take it. You will be started on a low dose at first, but your dose over time will most likely need to be increased to control your symptoms.

• Try to take co-careldopa at the same times of day each day, as this will help you remember to take it regularly. If you do miss a dose then take your next dose when it is due but leave out the missed dose. Do not take two doses together to make up for a forgotten dose.

• You can take the tablets either before or after a meal, although it is best not to take doses straight after large meals.

• Prolonged-release brands of co-careldopa (such as Caramet® CR, Half Sinemet® CR, and Sinemet® CR) and the combination brand called Stalevo®, are all formulated in a special way. These tablets should be swallowed whole - do not break or chew them.

• If you are using Duodopa® gel, your nurse will tell you how to use the cassette with a portable pump so that you receive the correct amount of medicine.

• Try to keep your regular appointments with your doctor. This is so your doctor can check on your progress. During the first few weeks of treatment in particular, your dose may require adjusting.

• Make sure you know exactly when to take your medication. Dose schedules and timings are important. Your pharmacist will be able to advise and help if you have difficulty in getting tablets out of blister packs, or if you have difficulty in remembering when to take your doses.

• Co-careldopa tablets are available in several different strengths. Each time you collect a fresh supply, it's a good idea to check the strength on the pack to make sure they are what you are expecting. If you are unsure, ask your pharmacist for advice.

• Co-careldopa can make your urine look a dark reddish colour. This is harmless and is nothing to worry about. It is caused by your body getting rid of the medicine.

• If you take any medicines that you have bought without a prescription, check with a pharmacist that they are suitable to take with co-careldopa. This is because some medicines, such as iron and some vitamins, may interfere with it.

• Sometimes people taking co-careldopa can fall asleep suddenly with little or no warning of being tired beforehand. Until you know how you react, take extra care if you drive, or if you operate machinery. If you do find yourself falling asleep suddenly, you should see your doctor as soon as possible for advice, and avoid driving a vehicle or using tools and machines in the meantime.

• Stay as active as possible and exercise regularly as much as you are able. You may walk more slowly than before, but a daily walk is good exercise and may help to loosen up stiff muscles.

• If you are a driver you should tell the DVLA and your insurance company that you have Parkinson's disease. Depending on the severity of symptoms and the medicines that you are taking, you may still be allowed to drive following a medical assessment.

• Treatment with medicines containing levodopa can sometimes cause problems with impulsive types of behaviour. If you notice any changes in your behaviour, such as an increased desire to gamble, binge eat, or spend excessively, or an increased sex drive, you must let your doctor know as soon as possible.

• If you are due to have an operation or dental treatment, tell the person carrying out the treatment that you are taking co-careldopa because there could be an increased risk of problems with some anaesthetics. Also, if you need to have any blood or urine tests, you must say that you are taking co-careldopa, because it can affect the result of some tests.

• There is a small increased risk of skin problems developing in people with Parkinson's disease, although the cause of this is unclear. It is a good idea to check your skin from time to time for any unusual patches, and to speak with your doctor if you are concerned.

• Continue to take co-careldopa regularly. Stopping treatment suddenly can cause serious problems. Your doctor will probably want you to reduce your dose gradually if this becomes necessary.

Can co-careldopa cause problems?

The table below contains some of the common side-effects associated with co-careldopa. You will find a full list in the manufacturer's information leaflet supplied with your medicine. Side-effects can sometimes occur when you first start taking medicines which contain levodopa, although most people have no problems with low doses. Unfortunately, most people taking levodopa over time (typically after several years) develop problems. These include muscle problems which can cause uncontrollable jerky movements, and 'on-off' effects (see below).

If you experience any other symptoms which you think may be due to co-careldopa, speak with your doctor or pharmacist for further advice.

How to store co-careldopa

• Förvara på en sval, torr plats, borta från direkt värme och ljus.

• If you are using Duodopa® gel, store the cassettes containing the gel in a refrigerator until they are required.
