Sweetners in medication

I was prescribed Carticure which is a spanish product for joints and cartilage. However, I was advised by GP not to take it because it has sorbitol (somehow our discussion didn't say which other similar medication to take). I'm looking for another similar medication but a sweetner (or without) suited for diabetics.
Which sweetners added to medications are generally safe for diabetes?I have yet to see one with Stevia or Truvia but probably the safest ( but not very tasty) are the ones without any sweetners.
Thanks

 

@EllieM I was having the gastrointestinal problems i.e. the "runs" (sorry if TMI)-to use another word-due to another medication, Probably adding sorbitol (a polyol) isn't great

Also was severely dehydrated so anything adverse, I didn't take.I don't know many grams of sorbitol there is in Carticure (had a quick look at the box).This is why I'm asking because it appears I have to take carticure or something similar.I would love to hear of any suggestions.

 

Thanks, that's good to know. Now I'll look up condroitin sulfate to see if that's okay to take.
Now just have to find something which would be the same but not adverse to diabetics.

 

Thanks,for your info . I didn't know glucosamine had an adverse reaction for insulin resistance. @Struma
All the same if it's not one thing ,it's another( can't take this medication because it interacts with another or it's not suitable for diabetes).

natural eggshell membrane ! I’m going to see if I can find it even though eggshell membranes do have glucosamine and condroitin( minimal amounts, good to know but it’s the only joint pain thing I can find).
