Common and Rare Side Effects of Lexapro (Escitalopram)

Lexapro (Escitalopram) is a widely prescribed selective serotonin reuptake inhibitor (SSRI) used to treat depression and generalized anxiety disorder (GAD). It works by increasing serotonin levels in the brain, improving communication between neurons and boosting mood. While highly effective, Lexapro may cause a range of side effects, from mild to serious. Understanding these can help patients manage them safely and maintain adherence to treatment.

Common Side Effects of Lexapro

Many patients experience mild side effects during the first few weeks of treatment. These often subside as the body adjusts to the medication. Common side effects include:

• Nausea or upset stomach
• Diarrhea
• Headaches
• Dry mouth
• Increased sweating
• Insomnia or excessive sleepiness
• Fatigue or weakness
• Nervousness or restlessness
• Sexual dysfunction (e.g., decreased libido)
• Flu-like symptoms

Most common side effects resolve within 1–2 weeks. Persistent or worsening symptoms should be discussed with a healthcare provider.

Serious Side Effects and Precautions

While rare, some individuals may develop serious side effects that require immediate medical attention:

• Sudden weight loss or gain
• Increased eye pressure, which may trigger angle-closure glaucoma in susceptible patients
• Severe headaches with confusion, muscle cramps, or weakness
• Menstrual irregularities, such as spotting or unexpected bleeding
• Symptoms of serotonin syndrome, including high body temperature, agitation, twitching, or confusion
• Abnormal heart rhythms or palpitations

Boxed Warning: Lexapro carries an FDA boxed warning for increased risk of suicidal thoughts in young adults. Always consult a healthcare provider about risks and benefits.
