Lexapro is a brand name in the United States for escitalopram oxalate, a prescription antidepressant medication that is used to treat symptoms of depression or anxiety in diagnosed individuals. This antidepressant belongs to the class of drugs known as selective serotonin reuptake inhibitors, or SSRIs. Research indicates that SSRIs may reduce symptoms of anxiety and depression by increasing the availability of the chemical messenger, or neurotransmitter, serotonin in the brain. The common side effects of Lexapro usually are mild, however, they should be considered before beginning this drug therapy.
Nausea
Nausea is a frequently reported side effect in individuals taking Lexapro. During clinical trials, RxList.com reports that 15 percent of depressed participants taking Lexapro experienced nausea compared to those in the placebo group. In clinical trials with anxiety disorder participants, nausea occurred in 18 percent of those patients compared to individuals in the placebo group. Other gastrointestinal side effects that can accompany nausea include constipation, diarrhea, indigestion, and stomach pain or discomfort. Typically, these side effects dissipate as the body gets adjusted to the medication; however, the doctor should be notified if such effects persist.
Insomnia
Lexapro may produce sleep-related problems, such as having trouble falling asleep or staying asleep throughout the night. The U.S. Food and Drug Administration states that during clinical trials, up to 14 percent of depressed participants experienced dose-dependent insomnia, and up to 6 percent of participants complained of feeling fatigued while taking Lexapro. On the other hand, 9 percent of participants reported the side effects of somnolence or drowsiness. While some side effects may be anticipated when beginning a new drug, the precise effects can be determined only after being on Lexapro in order to see how your body responds to it.
Sexual Dysfunction
A concern that many people have when they begin using antidepressant medications is that of associated sexual side effects. During placebo-controlled clinical trials, 12 percent of male participants taking Lexapro experienced ejaculatory problems, specifically, delayed ejaculation, reports RxList.com. Additionally, 6 percent of the male participants reported impotence problems. Females also experienced sexual difficulties such as decreased libido as well as an inability to reach orgasm, yet the incidence of sexual dysfunction in females was significantly lower than that seen in males. These side effects are considered to be temporary; however, the Mayo Clinic recommends consulting with a doctor if such problems persist.
Hypertension
According to the FDA, in some cases Lexapro may lead to electrocardiogram changes that are not considered to be acute or dangerous. In addition, hypertension, or high blood pressure, changes may occur as well as the experience of heart palpitations, or cardiac arrhythmias. Individuals considering this drug with a history of heart disease should discuss treatment options and side effects thoroughly with a physician to determine the best plan of treatment.
