If these problems appear suddenly after starting a new medication or a dose increase, contact your neurologist to have your medication adjusted temporarily.
Your neurologist may also prescribe domperidone (Motilium), a medication that blocks the dopamine receptors in the upper gastrointestinal tract. It causes the stomach muscles to contract so that food can move more easily through the gastrointestinal system.
If you have severe motor fluctuations, your neurologist might have you tested for Helicobacter pylori bacteria.
Here are a few steps you can take to mitigate your stomach problems:
- Adjust your eating habits—avoid fatty, oily foods and cream-based sauces.
- Try to avoid acidic foods, alcohol and coffee.
- Take your levodopa with food that does not contain protein (toast without butter, crackers, banana, apple sauce).
- Avoid taking your levodopa at the same time as your selegiline or rasagiline. Taking these medications together may increase the effects of the levodopa and its tendency to cause nausea.
