If too much drowsiness occurs, it may be necessary to use less medicine, use it less often, or stop using it completely. However, check with your doctor first before lessening your dose or stopping use of this medicine.
This medicine may cause dryness of the mouth. For temporary relief, use sugarless gum or candy, or melt bits of ice in your mouth, or use a saliva substitute. However, if your mouth continues to feel dry for more than 2 weeks, check with your medical doctor or dentist. Continuing dryness of the mouth may increase the chance of dental disease, including tooth decay, gum disease, and fungus infections.
