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;
