It looks like possibly the Light version is the one that contains that. The regular version doesn't seem to.
Light contains the following inactive ingredients: aspartame, citric acid, colloidal silicon dioxide, D&C Yellow No. 10, FD&C Red No. 40, flavor (natural and artificial Orange), maltodextrin, propylene glycol alginate and xanthan gum.
Cholestyramine for Oral Suspension USP contains the following inactive ingredients: acacia, citric acid, D&C Yellow No. 10, FD&C Yellow No. 6, flavor (natural and artificial Orange), polysorbate 80, propylene glycol alginate and sucrose.
I found that info on this page:

I would verify with your pharmacist though.
