Dizziness, lightheadedness, or fainting may occur, especially when you get up from a lying or sitting position . Getting up slowly may help. If this problem continues or gets worse, check with your doctor .

Maprotiline may cause dryness of the mouth . For temporary relief, use sugarless gum or candy, melt bits of ice in your mouth, or use a saliva substitute.
