Previous studies have found haloperidol, loxapine, trifluoperazine, olanzapine, risperidone, quetiapine, clozapine, and aripiprazole to be associated with dysphagia . Dysphagia is a rare adverse effect, but it is potentially dangerous to the patient. Fortunately, in most cases, this condition is reversible.
I have the same problem too but it was worse when I was on 6mg. Its why I went down to 5mg, it still happens but less often. I choke more with water and my own saliva sometimes even during sleep. My dr told me to drink more water but this didnt solve the issue. I know its the risperidone but its the only med I am really stable on.
