Sideeffects A medicine is only made available to the public if the clinical trials have shown that the benefits of taking the medicine outweigh the risks. Once a medicine has been licensed, information on the medicine's effects, both intended and unintended, is continuously recorded and updated. Some sideeffects may be serious while others may only be a mild inconvenience. Everyone's reaction to a medicine is different. It is difficult to predict which sideeffects you will have from taking a particular medicine, or whether you will have any sideeffects at all. The important thing is to tell your prescriber or pharmacist if you are having problems with your medicine. As part of treatment, this medicine may be used in combination with other medicines. There is no information available about the sideeffects of
Tolcapone when it is taken on its own. The information included here relates to the sideeffects caused by the combination of this medicine with other medicines that it is usually given with. There may be more information on the sideeffects of Tolcapone in the Patient Information Leaflet for Tolcapone.
