Later, in combination with levodopa, it can reduce levodopa requirements by 20-50%, and reduce levodopa's side effects. It may have a neuro-protective effect. One of the side-effects can be insomnia. >> For more on eldepryl, its side effects and a different form of it that seems to have greater positive effects w/ fewer side effects, try www.ceri.com for their information on PD.
