Side Effects of Escitalopram

Headache, ejaculation problems, increased sweating, and extreme tiredness are a few common side effects of escitalopram. Among the drug's uncommon side effects are asthma, shakiness (tremor), and liver problems. There are also some serious escitalopram side effects that you should report to your healthcare provider. These side effects can include hallucinations, a fast heart rate, and restlessness or an inability to sit still.

Side Effects of Escitalopram: An Introduction

As with any medicine, there are possible side effects with escitalopram oxalate (Lexapro®). Yet, not everyone who takes escitalopram will experience side effects. In fact, most people tolerate escitalopram well. When side effects of escitalopram do occur, in most cases they are minor and either require no treatment or can be easily treated by you or your healthcare provider.
(The side effects of escitalopram discussed below are not a complete list of side effects reported with escitalopram. Your healthcare provider can discuss a more complete list of side effects with you.)

Common Side Effects of Escitalopram

Escitalopram has been studied thoroughly in clinical trials. In these studies, side effects occurring in a group of people taking the drug are documented and compared to those that occur in another group not taking the medicine. This way, it is possible to see what side effects occur, how often they appear, and how they compare to the group not taking the medicine.
Based on these studies, the most common side effects of escitalopram include:
  • Headache -- up to 24 percent of people
  • Nausea -- up to 18 percent of people
  • Ejaculation problems -- up to 14 percent of people (see Lexapro Sexual Side Effects)
  • Extreme tiredness -- up to 13 percent of people
  • Insomnia -- up to 12 percent of people (see Lexapro and Insomnia)
  • Dry mouth -- up to 9 percent of people (see Lexapro and Dry Mouth)
  • Fatigue -- up to 8 percent of people
  • Increased sweating -- up to 8 percent of people
  • Diarrhea -- up to 8 percent of people
  • A decreased sex drive -- up to 7 percent of people
  • Orgasm Problems -- up to 6 percent of people
  • Constipation -- up to 6 percent of people
  • Dizziness -- up to 5 percent of people.


Some of these side effects, such as dizziness and nausea, might go away as your body adjusts to escitalopram. Others, such as sexual problems and dry mouth, are less likely to go away.
