If you’re considering Lexapro, adjusting your dose, or thinking about stopping it, it’s normal to have questions about what you might experience along the way.

Lexapro (escitalopram) is a commonly prescribed antidepressant used to support people managing anxiety and depression. Like many medications, it can come with side effects, especially during the first few weeks, during dose changes, or when discontinuing treatment.

With ReKlame Health, you can learn about the side effects of Lexapro. They may show up differently depending on your body, your dose, and whether you’re starting or stopping the medication.

How is Lexapro used?

Lexapro is a commonly prescribed medication used to support people experiencing a range of mental health conditions. It is most often used to treat depression and generalized anxiety disorder, but it may also be recommended for other concerns, such as panic disorder, social anxiety or obsessive-compulsive symptoms.

People living with depression may feel persistent sadness, low energy or a loss of interest in activities they once enjoyed. Anxiety-related conditions can show up as constant worry, restlessness, irritability or physical symptoms like a racing heart.

When these experiences begin to interfere with daily life, work or relationships, medication may be part of a care plan.

Lexapro works by helping balance serotonin, a brain chemical linked to mood and emotional regulation. It is often used alongside other forms of mental health care, such as lifestyle changes or supportive care, to help individuals feel more stable, focused and able to engage in everyday life.

What to know before starting or changing Lexapro

Before diving into specific symptoms, here are a few key things to keep in mind:

• Side effects may be temporary or reduce over time
• Your experience may vary based on your dose, metabolism, and overall health
• Changes (starting, increasing, or stopping) are when side effects may be most noticeable
• Working with a licensed provider is necessary for safer adjustments

Lexapro is a selective serotonin reuptake inhibitor (SSRI). This class of medication is thought to work by assisting serotonin absorption in the brain, which may improve mood. The medication can also affect other systems in the body, potentially leading to side effects. It can take time to create a noticeable effect.

1. Nausea and digestive changes

Lexapro may cause nausea, especially in the early stages of treatment.

You may notice:

• Upset stomach
• Mild nausea
• Changes in appetite
• Occasional diarrhea or constipation

These symptoms may improve as your body adjusts.

Tip: Taking Lexapro with food or at the same time each day may help reduce stomach discomfort.

2. Sleep disturbances

Lexapro may affect your sleep patterns in different ways.

Some people experience:

• Difficulty falling asleep
• Restlessness at night
• Vivid dreams

Others may feel:

• Increased drowsiness
• Daytime fatigue

Because of this, your provider may recommend taking Lexapro in the morning or evening, depending on how your body responds. If you miss a dose, take it when you can, unless you’re close to your next dose. Don’t take two doses close together.

3. Sexual side effects

Changes in sexual health are another commonly reported side effect of SSRIs, including Lexapro.

These may include:

• Reduced libido
• Difficulty achieving orgasm
• Erectile dysfunction in men

Are sexual side effects different for women?

Side effects of Lexapro in women can sometimes include more noticeable changes. Hormonal fluctuations may also play a role in how these symptoms are experienced.

If this side effect is impacting your quality of life, it’s important to speak with a provider. Adjustments to your dose or medication plan can often help.

4. Emotional blunting or feeling “flat”

Some people describe feeling emotionally numb or less reactive while taking Lexapro.

This may look like:

• Reduced emotional highs and lows
• Feeling “muted” or disconnected
• Less motivation or excitement

While this can make the negative feelings associated with anxiety and depression less sharp, it may feel uncomfortable if it dulls positive emotions as well.

A provider may help determine whether this is part of your adjustment period or a sign that your treatment plan needs to be refined.

5. Headaches and physical tension

Headaches are another potential side effect, particularly during:

• The first few weeks of starting Lexapro
• Dose increases
• Medication changes

You may also notice:

• Muscle tension
• Jaw clenching
• Mild body aches

These symptoms may be temporary and they could improve as your body adapts.

6. Weight changes and appetite shifts

Lexapro can affect appetite, which may lead to weight changes over time.

Some people experience:

• Increased appetite
• Cravings for certain foods
• Gradual weight gain

Others may notice:

• Reduced appetite
• Mild weight loss

Differences between men and women

While both men and women can experience weight changes, side effects of Lexapro in women may sometimes be influenced by additional factors, including menstrual cycle changes and metabolism differences.

Tracking your eating habits and discussing changes with a provider can help you stay aligned with your health goals.

7. Side effects of stopping Lexapro

If you’re thinking about discontinuing Lexapro, it’s important to understand that stopping suddenly can lead to withdrawal-like symptoms.

These are often referred to as side effects of stopping Lexapro or discontinuation symptoms.

Common experiences include:

• Dizziness or lightheadedness
• “Brain zaps” (brief electric sensations in the head)
• Irritability or mood swings
• Anxiety or restlessness
• Flu-like symptoms
• Sleep disturbances

These symptoms can vary in intensity. They typically appear within a few days of stopping or reducing your dose quickly.

Tapering may help

Gradually reducing your dose under medical supervision can help minimize these effects.

A tapering plan may:

• Allow your brain to adjust slowly
• Reduce the severity of symptoms
• Support a smoother transition off medication

When side effects are most likely to happen

Side effects of Lexapro may surface during:

• The first weeks of treatment
• Dose increases
• Dose decreases
• Discontinuation

In many cases, side effects improve within a few weeks. However, if they persist or interfere with your daily life, it’s worth checking in with a provider.

When to talk to a provider

You don’t have to manage side effects on your own.

Consider reaching out if you experience:

• Side effects that last longer than a few weeks
• Symptoms that worsen over time
• Significant changes in mood or functioning
• Difficulty sleeping, eating, or focusing

A provider can help you:

• Adjust your dose
• Switch medications if needed
• Build a plan that fits your goals and lifestyle
