Dry mouth is a common side effect of many antidepressants.
Blurred vision is a common side effect, but it usually goes away on its own within a couple of weeks of starting an antidepressant. With certain antidepressants, such as tricyclic antidepressants, it may be an ongoing issue.
Constipation is often associated with tricyclic antidepressants because they disrupt normal functioning of the digestive tract and other organ systems. Other antidepressants sometimes cause constipation as well.
Dizziness is more common with tricyclic antidepressants and monoamine oxidase inhibitors (MAOIs) than with other antidepressants. These medications can cause low blood pressure, resulting in dizziness.
Agitation, restlessness or anxiety can result from the stimulating effect of certain antidepressants. Although having more energy can be a good thing, it may mean you can't relax or sit still even if you want to. Be alert for racing or impulsive thoughts along with high energy. If these develop, talk to your doctor right away because they may be signs of bipolar disorder or another serious disorder.
