Lexapro (Escitalopram): Uses, Side Effects & What to Know

Lexapro (escitalopram) is an SSRI antidepressant used to treat major depressive disorder and generalized anxiety disorder (GAD). It helps reduce symptoms such as persistent sadness, excessive worry, irritability, tension, and difficulty concentrating.

Lexapro works by increasing the availability of serotonin, a neurotransmitter involved in mood, anxiety regulation, and emotional balance. By improving serotonin signaling, Lexapro helps stabilize mood and reduce anxiety over time.

Some people notice mild improvements in sleep, appetite, or anxiety within 1–2 weeks, but full antidepressant and anti-anxiety effects usually take 4–6 weeks or longer. Consistent daily use is important.

Yes. Some people experience temporary increases in anxiety, restlessness, or jitteriness during the first couple of weeks. These effects often improve as the body adjusts to the medication.

Common side effects include nausea, headache, fatigue, dizziness, dry mouth, sweating, sleep changes, and sexual side effects. Many side effects lessen over time.

Weight changes can occur, but Lexapro is generally considered weight-neutral to mild weight gain compared with some other antidepressants. Individual response varies.

Yes. Lexapro can cause decreased libido, delayed orgasm, or difficulty reaching orgasm in some people. If this occurs, a provider can discuss management options.

Alcohol is generally not recommended while taking Lexapro. Combining alcohol with Lexapro may increase drowsiness, dizziness, and worsen mood or anxiety symptoms.

Lexapro can interact with:

• Other antidepressants

• MAO inhibitors

• Certain migraine medications (triptans)

• Blood thinners and NSAIDs (increased bleeding risk)

• Supplements like St. John’s Wort

Always tell your provider about all medications and supplements you use.

If you miss a dose, take it when you remember unless it is close to your next dose. Do not double doses. Missing doses frequently may reduce effectiveness.

Lexapro should be tapered gradually under medical guidance. Stopping suddenly can cause discontinuation symptoms such as dizziness, nausea, irritability, anxiety, or “brain zaps.”

Withdrawal symptoms can occur, especially with abrupt stopping. Gradual tapering significantly reduces the risk and severity of symptoms.

Yes. Lexapro is commonly used long-term when monitored appropriately. Regular follow-ups help assess benefits, side effects, and ongoing need for treatment.

Contact a provider if you experience severe side effects, worsening depression or anxiety, suicidal thoughts, allergic reactions, or symptoms that interfere with daily life.
