You should get up carefully after sitting or lying down, especially if you have been doing so for long periods of time. You should use extra caution when getting up after sitting or lying down, especially during the beginning of treatment with carbidopa, entacapone and levodopa combination.
It is very important that you discuss new medications with your doctor before starting any new medications.
It is possible that you may experience hallucinations (seeing or hearing things that are not there) or an increase in dyskinesia (trouble in moving). Talk with your doctor if you have any questions about this.
It is possible that you may become nauseous, especially when you are first starting your medicine.
