My husband was having alot of trouble with his voice. It had gotten high and thready. He wasnt able to talk very much. He was pretty scared it was happening so quickly. The rilutek has helped the swallowing issues/voice issues. The neuro never mentioned anything about the possible reduction in cramping,fasciculations,improvement in QOL, nothing. Only mention was of a possible gain of 2-3 months of time. For us, this gave my husband a summer with his 12 yr old son. That has been priceless.
On the cost issue, the generic gets billed at around $1500 a month to insurance company. They pay about 10%. We have a $25 copay now. The generic they sent my husband the last time was manufactured in India.
