Most Lexapro side effects, like nausea, headache, fatigue, and sleep changes, are mild and improve within the first one to two weeks as your body adjusts. Serious side effects, including suicidal thoughts, severe allergic reactions, or symptoms of serotonin syndrome, are rare but require immediate medical attention. If side effects feel severe, worsen, or don’t improve after a few weeks, contact your psychiatric provider to discuss adjusting your dose or trying another option. Lexapro treatment at KIND includes close monitoring so any side effects get caught and addressed early.
- Common Lexapro side effects like nausea, drowsiness, and headaches usually fade within one to two weeks.
- Sexual side effects and weight changes can persist longer and are worth discussing with your provider.
- Serotonin syndrome and severe allergic reactions are rare but medical emergencies.
- Never stop Lexapro abruptly, as this can cause withdrawal-like discontinuation symptoms.
- A telehealth psychiatry provider can help you track side effects and adjust treatment quickly.
What Are the Most Common Lexapro Side Effects?
Lexapro (escitalopram) is a selective serotonin reuptake inhibitor (SSRI) commonly prescribed to treat depression and generalized anxiety disorder. Like most SSRIs, it comes with a set of common side effects that show up early in treatment.
- Nausea, often the most reported side effect in the first few days
- Headache, usually mild and temporary
- Fatigue or drowsiness, especially if taken in the morning
- Dry mouth
- Sleep changes, including trouble falling asleep or vivid dreams
These symptoms typically appear in the first one to two weeks and lessen as your body adjusts to the medication. Taking Lexapro with food or at the same time each day can reduce stomach discomfort and help you stay consistent. If you’re managing anxiety alongside depression, learn more about mood disorder treatment options that work alongside medication.
Which Side Effects Are Less Common but Still Considered Normal?
Some Lexapro side effects show up later or stick around longer than the initial adjustment period. They’re still considered normal, but they’re worth flagging to your provider.
- Reduced libido or delayed orgasm
- Weight changes, either gain or loss
- Increased sweating
- Vivid or unusual dreams
Unlike nausea or headaches, these effects may persist throughout treatment rather than fading after a couple of weeks. If sexual side effects or weight changes are affecting your quality of life, a follow-up conversation with your provider can help you weigh the benefits of staying on Lexapro against trying a different medication or adjusting your dose.
What Side Effects Mean You Should Call Your Provider Right Away?
A small number of Lexapro side effects are medical emergencies. Serotonin syndrome is a potentially life-threatening condition caused by excess serotonin activity in the body, marked by agitation, rapid heartbeat, and high body temperature. Knowing the warning signs can help you act fast.
- Signs of serotonin syndrome: agitation, rapid heart rate, high fever, and muscle twitching or rigidity
- Suicidal thoughts or worsening depression: especially important to watch for in patients under 25, particularly in the first few weeks of treatment
- Severe allergic reaction: rash, swelling of the face or throat, or difficulty breathing
- Unusual bleeding or bruising: SSRIs can affect platelet function, so unexplained bruising deserves attention
If you or someone you know experiences any of these symptoms, seek emergency care immediately or call 911. These reactions are rare, but they require fast action rather than waiting for a scheduled appointment.
Normal vs. Not Normal: Lexapro Side Effects Comparison
Here’s a side-by-side look at expected symptoms versus warning signs that need urgent attention.
| Symptom | Category | Typical Timeframe | Recommended Action |
|---|---|---|---|
| Nausea, headache, fatigue | Normal, mild | 1-2 weeks | Monitor at home; take with food |
| Sexual side effects, weight changes | Normal, longer-lasting | Can persist through treatment | Discuss at next follow-up |
| Suicidal thoughts, worsening mood | Emergency | Can occur anytime, especially early weeks | Seek emergency care immediately |
| Serotonin syndrome (fever, rigidity, rapid heart rate) | Emergency | Sudden onset, often within hours | Call 911 or go to the ER |
| Severe allergic reaction (rash, swelling, trouble breathing) | Emergency | Can occur anytime | Call 911 or go to the ER |
Tracking your side effects is much easier with a provider who checks in regularly and adjusts your treatment plan as needed. Schedule an appointment with Kind or call us at (469) 817-5554.
How Long Do Lexapro Side Effects Last?
Most Lexapro side effects fade within two to four weeks as your body builds tolerance to the medication. Nausea, headaches, and fatigue usually resolve first, often within the first two weeks. Sleep changes may take a bit longer to settle.
Sexual side effects and weight changes are the exception. These can last throughout the course of treatment for some people, which is why ongoing communication with your provider matters. It’s also important to remember that the full therapeutic effect of Lexapro for mood and anxiety symptoms may take four to six weeks to kick in, even after the initial side effects have faded.
If you’re unsure whether what you’re experiencing is a normal adjustment period or something that needs a treatment change, you can take a free self-assessment to get a clearer picture before your next appointment.
Can Residents Work in Telepsychiatry?
Yes, psychiatric residents can practice telepsychiatry as part of their training, but always under the supervision of a licensed clinician. This supervision requirement exists to make sure patients receive safe, accurate care even when a resident is involved in a visit. At KIND, providers are licensed, supervising clinicians who personally monitor medication side effects and adjust treatment plans as needed.
This matters to patients because it directly affects continuity of care. Knowing that a fully licensed provider is overseeing your treatment, rather than relying solely on a trainee, gives you confidence that side effects will be caught early and dosing decisions are clinically sound. It also means you won’t lose consistency in your care plan as your treatment progresses.
What Should You Do If You’re Having Side Effects on Lexapro?
Never stop taking Lexapro cold turkey, even if side effects feel uncomfortable. Discontinuation syndrome is a cluster of symptoms, such as dizziness, irritability, and flu-like feelings, that can occur when SSRIs like Lexapro are stopped too quickly. Instead, talk to your provider about a gradual taper if you need to stop or switch medications.
- Track your symptoms: Use a journal or app to note when side effects happen, how severe they are, and whether they’re improving.
- Bring your notes to your next visit: Detailed tracking helps your provider make an accurate, informed decision about your dose.
- Discuss alternatives if needed: Medications like Zoloft or Wellbutrin may be better options if Lexapro’s side effects don’t improve.
Schedule a telehealth follow-up to review your side effects with a provider who can help you decide whether to stay the course, adjust your dose, or try something new.
