Hello lobstahguy,It is a normal occurrence for anti-anxiety drugs such as Ativan to cause dry mouth in patients as well as some patients experience the sore throat problems.
In some instances, there may be no drugs suitable for substitution of the lorazepam. Nevertheless, it is possible for individuals prescribed Ativan to acclimate themselves to the condition. There are also many oral moisturizers or saliva substitutes that can provide relief for cottonmouth.
I would take a chance on salagen as well as consider using a product similar to THAYERS® Sugar-Free Dry Mouth Sprays and Lozenges deliver soothing, natural, instant moisture and relief from dry mouth and sore throats.
Another product that you may want to keep on your radar is MuGard which is a Rx prescription product that I have for dry mouth, sores in my throat and mouth from Chemotherapy.
I wish you well and do keep talking with us.
Kindly,
Kitt
