What is it and how is it used?

Comtess tablets contain entacapone and are used together with levodopa to treat Parkinson?s disease. Comtess aids levodopa in relieving the symptoms of Parkinson's disease. Comtess has no effect on relieving the symptoms of Parkinson´s disease unless taken with levodopa.


What do you have to consider before using it?

Do not takeComtess

  • if you are allergic (hypersensitive) to entacapone or any of the other ingredients of Comtess;
  • if you have a tumour of the adrenal gland (known as pheochromocytoma; this may increase the risk of severe high blood pressure);
  • if you are taking certain antidepressants (ask your doctor or pharmacist whether your antidepressive medicine can be taken together with Comtess);
  • if you have liver disease;
  • if you have ever suffered from a rare reaction to antipsychotic medicines called neuroleptic malignant syndrome (NMS). See section 4 Possible side effects for the characteristics of NMS;
  • if you have ever suffered from a rare muscle disorder called rhabdomyolysis which was not caused by injury.

Take special care with Comtess

Talk to your doctor if any of the following applies to you:

  • if you have ever had a heart attack or any other diseases of the heart
  • if you are taking a medicine which may cause dizziness or light-headedness (low blood pressure) when rising from a chair or bed;
  • if you experience prolonged diarrhoea consult your doctor as it may be a sign of inflammation of the colon
  • if you experience diarrhoea, monitoring of your weight is recommended in order to avoid potentially excessive weight loss;
  • if you experience excessive gambling or excessive sexual activity.
  • if you experience increasing loss of appetite, weakness, exhaustion and weight loss within a relatively short period of time, a general medical evaluation including liver function should be considered.

As Comtess tablets will be taken together with other levodopa medicines, please also read the package leaflets of these medicines carefully.
The dose of other medicines to treat Parkinson?s disease may need to be adjusted when you start taking Comtess. Follow the instructions that your doctor has given you.

Neuroleptic Malignant Syndrome (NMS) is a serious but rare reaction to certain medicines, and may occur especially when Comtess and other medicines to treat Parkinson?s disease are suddenly stopped or the dose is suddenly reduced. For the characteristics of NMS see Section 4 Possible side effects. Your doctor may advise you to slowly discontinue the treatment with Comtess and other medicines to treat Parkinson?s disease.

Comtess taken with levodopa may cause drowsiness and may cause you to sometimes suddenly fall asleep. If this happens, you should not drive or use any tools or machines (see Driving and using machines).

Taking other medicines

Please tell your doctor or pharmacist if you are taking or have recently taken other medicines, including medicines obtained without a prescription or herbal medicines. In particular please tell your doctor if you are taking any of the following:

  • rimiterole, isoprenaline, adrenaline, noradrenaline, dopamine, dobutamine, alpha-methyldopa, apomorphine;
  • antidepressants including desipramine, maprotiline, venlafaxine, paroxetine;
  • warfarin used to thin the blood;
  • iron supplements. Comtess may make it harder for you to digest iron. Therefore, do not take Comtess and iron supplements at the same time. After taking one of them, wait at least 2 to 3 hours before taking the other.

Pregnancy and breast-feeding
Do not use Comtess during pregnancy or if you are breast-feeding. Ask your doctor or pharmacist for advice before taking any medicine.

Driving and using machines
Comtess taken together with levodopa may lower your blood pressure, which may make you feel light-headed or dizzy. Be particularly careful when you drive or when you use tools or machinery.

In addition, Comtess taken with levodopa may make you feel very drowsy, or cause you to sometimes suddenly fall asleep.
Do not drive or operate machinery if you experience these side effects.

How is it used?

Always take Comtess exactly as your doctor has told you. You should check with your doctor or pharmacist if you are not sure.

Comtess is taken together with medicines containing levodopa (either levodopa/carbidopa preparations or levodopa/benserazide preparations). You may also use other medicines to treat Parkinson?s disease at the same time.

The usual dose of Comtess is one 200 mg tablet with each levodopa dose. The maximum recommended dose is 10 tablets per day, i.e. 2,000 mg of Comtess.

If you are receiving dialysis for renal insufficiency, your doctor may tell you to increase the time between doses.

Use in children

Experience with Comtess in patients under 18 years is limited. Therefore, the use of Comtess in children cannot be recommended.

If you take more Comtess than you should

In the event of an overdose, consult your doctor, pharmacist or the nearest hospital immediately.

If you forget to take Comtess
If you forget to take the Comtess tablet with your levodopa dose, you should continue the treatment by taking the next Comtesstablet with your next levodopa dose.

Do not take a double dose to make up for a forgotten tablet.

If you stop taking Comtess

Do not stop taking Comtess unless your doctor tells you to.

When stopping your doctor may need to re-adjust the dosage of your other medicines to treat Parkinson´s disease. Suddenly stopping Comtess and other medicines to treat Parkinson´s disease may result in unwanted side effects. See Section 2 Take special care.

If you have any further questions on the use of this product, ask your doctor or pharmacist.
