Lexapro (escitalopram) — what it does and what to watch for

Lexapro is a common SSRI antidepressant used for depression and anxiety. It can help mood, sleep, and daily function, but it doesn’t work overnight. Most people notice changes in 2–4 weeks, and the full effect may take 6–8 weeks. If you or someone you care about is starting Lexapro, here’s a clear, no-fluff look at how to use it safely.

How to take Lexapro safely

Doctors usually start adults on 10 mg once a day. Some people begin at 5 mg to reduce early side effects, and some need 20 mg later if symptoms persist. Take it at the same time every day — morning or evening, whichever fits your routine. You can take it with or without food. Don’t change the dose or stop suddenly; gradual tapering is safer to avoid withdrawal symptoms.

If you miss a dose and it’s close to your next one, skip the missed pill — don’t double up. Keep a list of every medicine, supplement, or herbal product you use; Lexapro interacts with several things. Always show that list to your prescriber and pharmacist.

Side effects, interactions, and red flags

Common side effects are nausea, tiredness, dry mouth, sweating, and sexual problems (lower libido or difficulty orgasming). These often settle after a few weeks. More serious but rare issues include severe mood changes, suicidal thoughts (especially in young people), serotonin syndrome (high body temperature, fast heartbeat, confusion), and severe allergic reactions.

Don’t combine Lexapro with MAO inhibitors, and be careful with triptans, tramadol, or herbal St. John's wort — mixing can cause serotonin syndrome. Also watch for increased bleeding risk if you take aspirin, NSAIDs, or blood thinners. If you drink alcohol, keep it minimal and talk to your doctor — alcohol can make side effects worse.

Call your doctor or get urgent care if you experience suicidal thoughts, sudden severe mood swings, chest pain, fainting, very fast heartbeat, or signs of serotonin syndrome like high fever, tremor, or extreme agitation.

Pregnant or breastfeeding? Talk to your clinician. Some studies link SSRIs to risks in pregnancy or newborn adaptation issues, so the doctor will balance those risks against the benefit of treating depression or anxiety.

Want to buy Lexapro online? Always use a licensed pharmacy and expect to show a valid prescription. Avoid unverified overseas sites that sell without prescription — they can send wrong or counterfeit pills. Many legitimate pharmacies offer telehealth visits and pharmacist help if you need an easier route to care.

Follow up with your prescriber about 4 weeks after starting or changing dose. Track mood, sleep, side effects, and any new symptoms. That simple check-in helps fine-tune treatment and keeps you safe while you get better.
