Thanks for following up. I've been taking cevimeline since mid-October. I found the same Mayo Clinic warning you did. So I reached out to my rheumatologist. Long story short, doctor said nausea is uncomfortable, vomiting I should be concerned about ;. to rule out concern, I would probably need to go to an ER. Nausea began middle of night i think and continued till evening today. I've stopped taking it for today. I guess I can start tomorrow again (based on the doctor's brief posts to my questions).
In terms of what yo are reading - that it's our saliva.], that's great news --assuming you have a reliable source. Where did you find this research? - I just googled information about the medication etc.. and found some information I probably did not save ;and don't know if it's reliable. The info suggested that the saliva produced is not adequate to protect my teeth- as did my dentist. I was hoping to look over research at some point. Thanks again!
