Possible, but unlike: Not likely. This is a pure h2 blocker with little to no anti-cholinergic side-effects. Is he on other meds? Is he a mouth breather at night? Does he snore? I would elsewhere. Plus, not close to the maximal dose. My bet is sometrhing else!

Yes: Dry mouth is a common side effect of this medication. So it is important to treat the dry mouth in order to prevent cavities. First regular dental exams and cleaning are essential. Avoid sugary foods and drinks. Chew xylitol or sugar free gum to stimulat saliva. Avoid alcohol mouth rinses. Perscription Fluoride toothpaste or mi paste will help prevent decay. Talk to dentist for more.
