For Parkinson's Disease "I was taking Pramipexole for a few years and got pulled into a gambling addiction. I went off of Pramipexole in 02/2025 and the doctor prescribed Amantadine. The first few days were amazing. It felt like I didn’t have Parkinson’s at all. Then the side effects started. I started seeing my ankles swelling, was having severe insomnia, noticed dysarthria as I started to stutter and struggle to pronounce words. This was during the second week on Amantadine. I started to have problems with my bladder and it was taking over 3 minutes to empty my bladder. I was going to the bathroom a lot. I should mention that I was taking Rytary, in addition to the Amantadine. I was depressed a lot and started to lose my balance and became wobbly. My tremors were going away, so I was pushing through the first few months living with the side effects. These side effects were getting worse in May of 2025 and I had 3 falls. I got off of Amantadine in June and I have seen improvements in all of my side effects."

For Parkinson's Disease "Started Amantadine 4 weeks ago, 200 mg per day. Noticed immediately occasional dizziness and diarrhea after every 100 mg capsule, lost any desire to get up and do anything. Midway through the third week, I cut my dosage down to 100 mg capsule per day, taken every evening at 8 pm before bedtime, and that helped me sleep better and as well increased movement in arms and right leg and foot. Happy to say I am very pleased with the results!"

Amantadine for Parkinson's Disease "I've only been on Amantadine for six weeks for dystonia/dystonic tremors/probable early onset of Parkinson's, and the Symmetrel has helped the tremors tremendously. There are side effects, i.e., dizziness, imbalance, strange dreams, dry mouth."

For Parkinson's Disease "I started taking it 2 weeks ago and noticed my tremors calmed down immediately. The side effects, however, are becoming unbearable. Insomnia and dizziness have been the main symptoms. I’ll give it a few more weeks before I call the doctor."

For Parkinson's Disease "I have to say I noticed the wiggles disappeared after the first dose - I hope this continues to work. I did get a brief dizzy spell after the second dose, but it quickly passed."
