Ambien causes seizures?
Short answer - Yes. There is always an underlying condition, sometimes previously not diagnosed.
Thinking the same thing
Ambien is a drug that can alter one’s mental functioning and can cause seizures. Listen to some of the side effects of drugs advertised on television. You will be surprised at what people are willing to have a side effects to get to sleep, to have clear skin, or to “fix” another ailment. Every prescription in the USA comes with a pamphlet that lists the KNOWN side effects of the medication. Most people simply toss those pamphlets away as if they were parsley on a burger. They expect nothing bad can happen because “after all, the medication was prescribed by my doctor”. A good doctor will tell a person the side effects before prescribing a medication and will follow up by asking questions because good doctors know most patients are either illiterate or choose to be no more informed than the person who cannot read.
