• if you have a tumor of the adrenal gland (known as pheochromocytoma, this may increase the risk of severe hypertension);

• if you have a liver disease;
• if you have ever had a rare reaction to antipsychotic medications called Neuroleptic Malignant Syndrome (NMS). See section 4 “Possible side effects” for NMS characteristics;

• if you have ever had a heart attack or any other heart disease;
• if you are taking any medication that may cause dizziness or lightheadedness (low blood pressure) when standing up from a chair or bed;
• if you experience prolonged diarrhea. Consult your doctor as it may be a sign of colon inflammation;
• if you experience diarrhea, it is recommended to control your weight to avoid excessive weight loss;
• if you experience increasing loss of appetite, weakness, fatigue, and weight loss over a relatively short period of time, a general medical evaluation including liver function should be considered.

Inform your doctor if you or your family/caregiver notice that you are developing unusual desires or tendencies to behave in an unusual way in you or that you cannot resist the impulse, determination, or temptation to perform certain activities that may harm you or others. These behaviors are called impulse control disorders and may include excessive gaming, eating, or spending, and an abnormally elevated or excessive sexual impulse or concern about increased sexual thoughts or feelings.Your doctor may need to review your treatment.

As Comtan must be taken together with other medications containing levodopa, read also carefully the leaflet of these medications.

It may be necessary to adjust the dose of other medications to treat Parkinson's disease when starting to take Comtan. Follow the instructions as indicated by your doctor.

Neuroleptic Malignant Syndrome (NMS) is a rare but severe reaction to certain medications, and may appear especially when Comtan and other Parkinson's disease medications are suddenly stopped or reduced. For NMS characteristics, see section 4 “Possible side effects”. Your doctor may advise you to gradually discontinue treatment with Comtan and other Parkinson's disease medications.
