Yes, I believe some medications gave me slurred speech. Which one(s), I don't completely recall. My gut feeling tells me that it was just an issue when first starting a medication (like Geodon) or if I was in the hospital and they loaded me up with a huge dose of something when I was manic w/psychosis (and surely severely agitated), like Haldol.

I do remember that when I first started taking Geodon I found it very sedating. I recall when first put on it that my husband and I had our neighbor over for dessert or something and I started falling asleep sitting up. I ended up having to excuse myself. It was OK since my neighbor prefers my husband over me anyway. Eventually I got used to Geodon and it wasn't that sedating at all.

Also, one time my careless husband accidentally took MY evening medications in the morning instead of his morning medications. The two pill boxes looked similar. I knew the difference, but it was one morning when I didn't give it to him, which is our usual custom. The poor dude made it to work alright, but then he apparently started to slur his words and fall asleep, almost falling off his chair. He managed to call me and asked me to check what pills he took. Sure enough, they were mine. I had to drive to his workplace and take him home. At home he slept around 12 hours straight. Probably if I had taken my evening meds in the morning I would have just been very tired but manage, because I'm used to them. But he wasn't used to my large doses of Geodon and Seroquel XR.

Once I took my morning medications twice one morning. They didn't sedate me or make me slur words, but I felt very strange. I had to reduce some of my evening meds that night as a result.
