I'd like to share anectdotal reports of my use of amantadine in children. Amantadine is a medication that is not used much in child psychiatry. It was originally developed for the treatment of flu symptoms. It was later found to be helpful in Parkinson's. I ran across an article about using it for the treatment of ADHD in the late 80"s. I have always kept it "in my back pocket" in case I needed an alternative to traditional ADHD medication when there was a history of tics, bipolar or an intolerance to stimulants. I have had some very good results in the treatment of ADHD with amantadine with very few side effects. The most common side effects are a decrease in appetite, weight loss and upset stomach. Dizziness can also occur.
It can be a a good option that shouldn't be overlooked.
Amantadine comes in liquid and 100mg capsules. The maximal dose is 100mg three times a day.
