Countess – Entacapone uses, dose and side effects


200 mg film-coated tablets 

1. What Comtess is and what it is used for

Comtess tablets contain entacapone and are used with levodopa in the treatment of Parkinson’s disease. Comtess helps levodopa reduce the symptoms of Parkinson’s disease. Comtess has no relieving effect on Parkinson’s symptoms without concomitant treatment with levodopa.

2. What you need to know before taking Comtess

Do not take Comtess

  • if you are allergic to entacapone or to peanuts or soy or any of the other ingredients of this medicine (listed in section 6);
  • if you have a tumor in the adrenal gland ( pheochromocytoma ), as it may increase the risk of severe high blood pressure;
  • if you are taking certain antidepressants (ask your doctor or pharmacist if your antidepressant can be taken with Comtess);
  • if you have liver disease;
  • if you have previously had a rare reaction to antipsychotics called neuroleptic malignant syndrome (NMS). See section 4 Possible side effects, for a description of NMS;
  • if you have previously had the rare muscle disease rhabdomyolysis that was not caused by the injury.

Warnings and cautions

Talk to your doctor or pharmacist before taking Comtess:

  • if you have had a heart attack or any other heart disease;
  • if you are taking medicines that may cause dizziness or dizziness (low blood pressure ) when you get up from a chair or bed;
  • if you experience prolonged diarrhea, consult a doctor as this may be a sign of colitis;
  • if you get diarrhea, recurrent weight control is recommended to avoid any excessive weight loss;
  • If you experience an increased appetite, weakness, fatigue, and weight loss in a relatively short time, you should undergo a general medical examination, including an examination of liver function.

Tell your doctor if you or your family/caregiver discovers that you are developing impulses or wanting to behave in ways that are unusual for you, or that you cannot resist the impulse, the drive, or the temptation to engage in a certain activity that may harm yourself or others. This behavior is called impulse control disorder and may include compulsive gambling, excessive food intake or spending, an abnormally high sex drive, or a preoccupation with an increase in sexual thoughts or feelings. Your doctor may need to review your treatment.

Because Comtess tablets are taken with other levodopa medicines, also read the package leaflet for these other medicines carefully.

When you start taking Comtess, you may need to adjust the dose of one of your other medicines for Parkinson’s disease. Follow the instructions given to you by your doctor.

Neuroleptic malignant syndrome (NMS) is a severe but unusual reaction to certain medicines and can occur especially when you suddenly stop taking Comtess and other medicines for Parkinson’s disease or when the dose is suddenly reduced. For a description of NMS see section 4 Possible side effects. Your doctor may ask you to slowly stop treatment with Comtess and other medicines for Parkinson’s disease.

Concomitant use of Comtess and levodopa may cause drowsiness and may at some point cause you to suddenly fall asleep. If this happens, do not drive or use machines (see “Driving and using machines”).

Other medicines and Comtess

Tell your doctor or pharmacist if you are taking, have recently taken, or might take any other medicines. Tell your doctor especially if you are taking any of the following:

  • rimiterol, isoprenaline, adrenaline, noradrenaline, dopamine, dobutamine, alpha methyldopa, apomorphine;
  • antidepressants such as desipramine, maprotiline, venlafaxine, paroxetine;
  • warfarin (blood-thinning drug);
  • iron supplements. Comtess can make it harder to absorb iron. Therefore, do not take Comtess and iron supplements at the same time. After taking one medicine, wait at least 2-3 hours before taking the other.

Pregnancy, breastfeeding, and fertility

Do not use Comtess during pregnancy or breast-feeding. If you are pregnant or breast-feeding, think you may be pregnant, or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine.

Driving and using machines

Comtess together with levodopa can cause low blood pressure and dizziness. Be extra careful when driving and when using machines.

In addition, Comtess with levodopa may cause severe drowsiness or you may suddenly fall asleep.

Do not drive or use machines if you experience these side effects.

If you forget to take Comtess

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

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

If you stop taking Comtess

Do not stop using Comtess without consulting your doctor.

When you stop, your doctor may need to change the dose of one of your other medicines for Parkinson’s disease. Abrupt discontinuation of Comtess and other Parkinson’s medicines may result in unwanted side effects. See section 2 Warnings and Precautions.

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