Does medication cause stuttering?

Does medication cause stuttering? I’ve recently realized that I started to develop a stutter. I would mix words that shouldn’t go together or stammer even though I had the word in my head. This has never happened to me before and if it did, it was like a one time thing. It’s been going on for a couple of months now and I’m curious whether it is because of the vitamins I’m taking. (Natures Valley B-complex) Would be great if someone could let me know.
