About Prolopa

What Prolopa is used for

PROLOPA belongs to a group of medicines called antiparkinson agents which are used to treat the signs and symptoms of Parkinson's disease. Signs and symptoms of Parkinson's disease include: shaking (tremor), slowness in performing activities of daily living (bradykinesia), muscle stiffness (rigidity) and mood changes (depression).

What Prolopa does

The symptoms of Parkinson's disease are caused by a deficiency of a natural substance (dopamine) in the part of the brain affected by Parkinson's disease. PROLOPA helps to replace this substance.

Warnings and Precautions

Some people feel sleepy, drowsy, or, rarely, may suddenly fall asleep without warning (i.e. without feeling sleepy or drowsy) when taking PROLOPA. During treatment with PROLOPA take special care when you drive or operate a machine. If you experience excessive drowsiness or a sudden sleep onset episode, refrain from driving and operating machines, and contact your physician.

Studies of people with Parkinson's disease show that they may be at an increased risk of developing melanoma, a form of skin cancer, when compared to people without Parkinson's disease. It is not known if this problem is associated with Parkinson's disease or the drugs used to treat Parkinson's disease. Therefore, your doctor should perform periodic skin examinations.

BEFORE you use PROLOPA talk to your doctor or pharmacist if you:

  • have or have had any other health problems including: convulsions, diabetes, stomach ulcers, depression or other psychological disorders, osteoporosis, clots in your veins, irregular heart rhythm or history of heart attack, glaucoma, skin cancer or suspicious skin cancer

  • drive or operate machinery

  • are pregnant or plan to become pregnant

  • are breast-feeding or wish to breast-feed

  • are allergic to any other medicines, foods, dyes or preservatives

  • are going to have an operation that requires general anesthesia (see Interactions with This Medication:)

Interactions with Prolopa

Drugs that may interact with PROLOPA include:

  • sympathomimetic drugs, such as cough and cold medications containing epinephrine, isoproterenol or amphetamine

  • blood pressure lowering medications

  • other antiparkinsonian medications

  • some medications used to treat mental problems

  • general anesthetics with halothane. If you know you are going to have an operation, that requires this type of anesthesia, you should stop PROLOPA 12-48 hours beforehand.

  • iron tablets or multivitamin tablets containing iron

Protein-rich diets (for example, a lot of meat, poultry or fish) may reduce the beneficial effects of PROLOPA.

Proper Use of Prolopa

Usual dose

Your doctor will decide how many PROLOPA capsules you will need to take each day.

You should always follow your doctor's instructions about how many PROLOPA capsules to take each day and when you should take them.

You should swallow the capsules whole, with water. Do not open capsules or dissolve in liquid.

The amount of PROLOPA your doctor prescribes will depend on your individual symptoms and your response to treatment. When you first start taking PROLOPA the amount you take will be increased gradually. The amount has to be carefully adjusted for each person as your Parkinson's symptoms will not be controlled if you take too little PROLOPA and if you take too much PROLOPA, you may experience unwanted side effects. It may be several weeks before the best dose for you is reached.

Keep taking your medication, as instructed, until your doctor tells you to stop.

Do not stop taking this medication abruptly.


If you take more than the scheduled dose, contact your doctor or pharmacist immediately to find out what needs to be done.

Missed dose

If you have missed a dose, take it as soon as you remember. If it is almost time to take your next capsule, do not take the missed capsule, but carry on with your regular schedule.

Side Effects for Prolopa and What to Do About Them
