Using amantadine together with paliperidone may increase side effects such as dry mouth, constipation, difficulty urinating, heat intolerance, confusion, and blurred vision.

Side effects may be more likely to occur in the elderly or those with a debilitating condition. Talk to your doctor if you have any questions or concerns. Your doctor may be able to prescribe alternatives that do not interact, or you may need a dose adjustment or more frequent monitoring to safely use both medications. You should avoid or limit the use of alcohol while being treated with these medications. Also avoid activities requiring mental alertness such as driving or operating hazardous machinery until you know how the medications affect you. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.
