Is anyone taking medicine for ALS

I asked this question to Neurologist, but I’m afraid his doctor doesn’t know as he hasn’t treated many patients with ALS. Could it be possible that the drug Rilutek could be working in the opposite way? I know that this drug is suppose to slow down the progression of this diseases, nut I find it to be very odd that there was very little progression in my father’s case until he went on Rilutek. Is anyone taking this medicine for ALS?

My father was diagnosed with ALS. He sought psychiatric professional help as well as anti-depressants. Now he no longer needs the pills and has stopped seeing a psychiatrist. He has no experience with Rilutek, but those meds are tricky. Please, consult some specialist about this.
