Take your medication on time, every time. This helps in keeping the dopamine level steady in your brain thus avoiding sudden ups and downs, causing uncomfortable symptoms of PD or side effects from the medication. Also, a regular routine allows your specialist to decide more easily how to adjust your medications to help you.
Take your medication at least a half-hour before eating or drinking protein, or, take the medication an hour after you have had protein. Protein interacts with levodopa, negating much of its purpose.
Take your medication with a full glass of fluid. This helps to flush the tablets down to where they can get absorbed. A person with PD often has slower digestive tract muscles so medications can get stuck along the way.
Try to ensure you are never constipated. If you are 'backed up', then the medications do not get absorbed nearly as well.
