Lexapro (Escitalopram) Tablets

Lexapro is the brand name under which escitalopram, a selective serotonin reuptake inhibitor (SSRI), is sold as an oral tablet. We offer it in 5 mg, 10 mg, and 20 mg strengths, with packages of 10, 20, 30, 60, 90, 120, 180, 270, or 360 pills. Escitalopram is one of the most widely prescribed antidepressants worldwide, valued for its relatively clean side-effect profile and predictable dosing. The sections below explain what Lexapro is, how it works, how it is generally used, and what to know about safety, interactions, and alternatives.

What Is Lexapro?

Lexapro's active ingredient, escitalopram, is the S-enantiomer of citalopram and the enantiomer responsible for most of citalopram's serotonin reuptake inhibition. It belongs to the SSRI class, a group of medicines that increase the availability of serotonin in the brain by blocking its reabsorption at nerve terminals. Each Lexapro tablet is taken orally, once daily, and is manufactured as an immediate-release formulation rather than an extended-release product. Because escitalopram is a mature, extensively studied molecule, its pharmacological behaviour, dosing pathways, and safety profile are well established in clinical practice.

Depression and Anxiety: Why Treatment Matters

Major depressive disorder and generalized anxiety disorder are common, treatable conditions that affect mood, energy, sleep, concentration, and day-to-day functioning. Left unaddressed, they can persist for months or years and increase the risk of complications, including impaired work or family life and, in more severe cases, thoughts of self-harm. Pharmacological treatment with an SSRI such as escitalopram is one of the standard first-line approaches, often used alongside psychotherapy, lifestyle changes, or both. Readers wanting a broader view of related treatment categories may find it useful to browse our AntiDepressants and Anxiety sections while comparing options.

How Escitalopram Works

Escitalopram selectively inhibits the serotonin transporter (SERT), the protein responsible for pulling serotonin back into presynaptic neurons after it has been released into the synaptic gap. By blocking this reuptake, escitalopram allows serotonin to remain active in the synapse longer, gradually adjusting receptor sensitivity and downstream neural signalling over several weeks. Unlike older tricyclic antidepressants, escitalopram has minimal affinity for histamine, adrenergic, or muscarinic receptors, which is why it tends to cause less sedation, weight gain, or dry mouth than earlier antidepressant classes. Clinical improvement in mood is not immediate; most people notice initial changes in sleep, appetite, or energy within one to two weeks, while the fuller antidepressant or anxiolytic effect typically develops over four to six weeks of consistent use.

Evidence Behind Escitalopram's Use

Escitalopram's efficacy has been examined in numerous randomized, placebo-controlled trials and head-to-head comparisons with other antidepressants, consistently showing meaningful separation from placebo in reducing depression and anxiety symptom scores. Comparative analyses, including large-scale network meta-analyses of antidepressants, have repeatedly placed escitalopram among the better-tolerated and more consistently effective options within its class. This body of evidence supports its continued use as a first-line SSRI for adults with major depressive disorder or generalized anxiety disorder, though individual response varies and no antidepressant works identically for every patient.

Formulation and Strengths

Lexapro tablets are film-coated, oral, immediate-release tablets containing escitalopram as the sole active ingredient. We currently list this exact tablet form in 5 mg, 10 mg, and 20 mg strengths, allowing a prescriber to start low and adjust the dose as needed without switching products. Escitalopram is also marketed in several countries, including Canada, under the brand name Cipralex; both brand names describe the same active ingredient in equivalent tablet strengths, though the two brands are approved and distributed through different regulatory pathways depending on the market.

What Lexapro Is Used For

Escitalopram is established for treating major depressive disorder and generalized anxiety disorder in adults. Prescribers also use it, based on clinical judgment, for related conditions such as panic disorder, social anxiety disorder, and obsessive-compulsive symptoms, although approved indications vary by country. It is not a fast-acting sedative or an as-needed anxiety reliever; its role is to gradually stabilize mood and reduce excessive worry through sustained daily use rather than through a single-dose effect.

Dosage Forms and General Dosing Principles

For adults with major depressive disorder or generalized anxiety disorder, escitalopram is commonly started at 10 mg once daily. Based on response and tolerability, a prescriber may increase the dose to a maximum of 20 mg once daily, generally after at least one week. Some people may start at 5 mg to improve initial tolerability, while older adults and people with reduced liver function, substantial interacting medicines, or known slow CYP2C19 metabolism may require a lower dose, a lower maximum, or slower titration.

Escitalopram can be taken in the morning or evening, with or without food, since food has little effect on its absorption. It is best taken at about the same time each day. Because abrupt discontinuation after weeks of regular use can cause symptoms such as dizziness, irritability, sensory disturbances, or sleep problems, dose reduction is usually done gradually under medical guidance rather than stopped suddenly. These are general principles describing how escitalopram is commonly used in practice; an individual's exact starting dose, target dose, and titration schedule should always be set by the prescriber managing that person's care.

Elimination and Half-Life

Escitalopram is metabolized mainly in the liver, principally through the CYP2C19 enzyme pathway with additional contributions from CYP3A4 and CYP2D6, producing metabolites that are considerably less pharmacologically active than the parent compound. Its elimination half-life is approximately 27 to 32 hours in adults with normal liver function, which supports stable once-daily dosing and means that a missed dose does not cause an abrupt drop in blood levels. Steady-state concentrations are generally reached after about one week of consistent daily dosing. People with reduced liver function, older adults, or those who are known to metabolize CYP2C19 substrates slowly may clear escitalopram more slowly and can require a more cautious dosing approach, which is one reason organ function is often reviewed before and during treatment.

Important Safety Information

Antidepressant safety information warns about an increased risk of suicidal thinking and behaviour in children, adolescents, and young adults, particularly during the early weeks of treatment or after a dose change; escitalopram itself is not indicated for use under 18 years of age in Canada. All patients starting or adjusting treatment benefit from monitoring for worsening mood, agitation, or unusual behavioural changes, especially in the first several weeks. Escitalopram can also affect judgment, alertness, or coordination in some people, so caution around driving or operating machinery is reasonable until an individual knows how the medication affects them. In pregnancy, Canadian prescribing information advises against use unless the expected benefit to the mother outweighs potential risks, given reports of neonatal adaptation symptoms and, rarely, persistent pulmonary hypertension of the newborn when used in the third trimester; abrupt discontinuation during pregnancy is generally avoided. Escitalopram and its metabolite pass into breast milk, so continuing treatment while breastfeeding is a decision made individually with a clinician, weighing infant monitoring for sedation or feeding difficulty against the mother's need for treatment. People with diabetes should be aware that SSRIs can occasionally alter glucose control, sometimes requiring adjustment of insulin or oral antidiabetic medication.

Prescription Requirements and Ordering Through Our Pharmacy

Escitalopram is classified as a prescription medicine in Canada; Cipralex has Drug Identification Number listings in Health Canada's Drug Product Database, and Lundbeck Canada Inc. is identified as its Canadian sponsor. That regulatory classification describes how the medicine is controlled in the Canadian marketplace generally. Separately, our own ordering process for Lexapro does not require you to submit a prescription before we accept an order, which is why we are able to offer it without prescription paperwork slowing down your purchase. We have supported customers since 2018, and our support team is reachable every day of the week by email or online chat, with a pharmacist available to answer questions about dosage forms, strengths, or general use before or after you order.

Who Should Avoid Escitalopram

Escitalopram should not be used by anyone with a known hypersensitivity to escitalopram, citalopram, or any tablet ingredient. It is contraindicated in combination with monoamine oxidase inhibitors (MAOIs), both during concurrent use and within the recommended washout periods before or after switching, because of the risk of serotonin syndrome. It should also be avoided in people with congenital long QT syndrome or other conditions associated with significant QT-interval prolongation, given escitalopram's own modest dose-related effect on cardiac repolarization. As noted above, it is not indicated for use in children or adolescents, and its use in pregnancy or breastfeeding calls for individual clinical judgment rather than routine use.

Drug Interactions

Escitalopram interacts with several other medicine groups in ways that matter for both safety and effectiveness, ranging from a serious contraindication with MAOIs to more moderate cautions with drugs that affect bleeding, heart rhythm, or its own metabolism. The table below summarizes the most clinically relevant categories, along with what typically happens and what is usually done about it.

Beyond these categories, medicines that inhibit CYP2C19 can raise escitalopram blood levels, while medicines that induce relevant metabolic enzymes may lower its levels and effectiveness. Always tell your prescriber or pharmacist about every prescription medicine, over-the-counter product, and herbal supplement you take, including St. John's Wort, which itself has serotonergic activity and should generally not be combined with an SSRI.

Side Effects: What to Expect and When to Act

Most people who start escitalopram experience mild, temporary effects as the body adjusts, including nausea, dry mouth, drowsiness or, conversely, mild insomnia, sweating, and reduced sexual interest or function. These effects often ease within the first two to four weeks and are generally manageable, though sexual side effects can persist for some people throughout treatment and are worth discussing with a prescriber if they are troublesome. A smaller number of people notice increased anxiety or restlessness (akathisia) in the initial days after starting or increasing a dose, which usually settles but should be mentioned to a healthcare provider if it is severe or persistent.

Some effects call for prompt medical attention rather than simple monitoring. These include:

• Signs of serotonin syndrome, such as high fever, muscle rigidity or twitching, rapid heartbeat, confusion, or heavy sweating, particularly when combined with another serotonergic medicine.
• Unusual bleeding or bruising, especially when escitalopram is combined with an anticoagulant, antiplatelet medicine, or non-steroidal anti-inflammatory drug.
• New or worsening suicidal thoughts, severe agitation, or dramatic mood or behaviour changes, especially in the first weeks of treatment or after a dose change.
• Signs of a fast or irregular heartbeat, fainting, or severe dizziness, which can indicate a cardiac rhythm effect.
• Signs of a severe allergic reaction, such as facial swelling, difficulty breathing, or a widespread rash.

Anyone experiencing these signs should seek urgent medical assessment rather than waiting for a routine follow-up appointment.

Overdose and Toxicity

Escitalopram taken in excess of the prescribed amount can cause exaggerated versions of its common side effects along with more serious findings such as marked drowsiness, tremor, vomiting, rapid heart rate, seizures, and, in more severe cases, QT-interval prolongation or serotonin syndrome. Combining an overdose with alcohol, sedatives, or other serotonergic medicines increases the risk of a dangerous outcome. Suspected overdose is a medical emergency; the person should receive urgent hospital assessment, where treatment is generally supportive, involving cardiac monitoring, airway management if needed, and specific treatment of complications such as seizures or serotonin syndrome, since there is no specific antidote for escitalopram.

Storage Instructions

Store Lexapro tablets at 25 °C; brief excursions between 15 °C and 30 °C are permitted during ordinary handling and transport. Keep the tablets in their original, tightly closed container, away from moisture and out of direct light, and store them out of reach of children and pets. Do not use tablets beyond their labelled expiry date, and dispose of any unused or expired medicine through a pharmacy take-back program rather than household waste.

Benefits and Trade-offs

Escitalopram's main advantages are its once-daily dosing, its relatively favourable tolerability compared with older antidepressant classes, its well-characterized interaction profile, and decades of accumulated prescribing experience across a wide range of patients. Its trade-offs include a gradual onset of benefit rather than immediate relief, the possibility of sexual side effects or emotional blunting in some users, and the need for a gradual taper rather than abrupt stopping. For people who do not tolerate escitalopram well or who have an inadequate response, prescribers sometimes add an augmenting agent, such as low-dose aripiprazole (Abilify), rather than switching antidepressants outright, particularly in partial responders. Choosing between escitalopram and another SSRI or SNRI usually comes down to individual tolerability, other medicines being taken, and prior response to treatment rather than any single medicine being universally superior.

Generic Escitalopram and Therapeutic Alternatives

Generic escitalopram tablets contain the same active ingredient, strength for strength, as Lexapro, and are considered therapeutically equivalent by regulatory bodies that approve generic substitution; the practical difference is typically price and tablet appearance rather than clinical effect. Citalopram, escitalopram's parent molecule, is a related but distinct SSRI that some people tolerate differently. Other SSRIs, such as sertraline, fluoxetine, and paroxetine, including Paxil, share the same general mechanism but differ in half-life, interaction profile, and side-effect emphasis, while SNRIs such as venlafaxine and duloxetine add a norepinephrine component that can suit different symptom patterns. Bupropion, which works through dopamine and norepinephrine rather than serotonin, is sometimes chosen specifically to avoid SSRI-related sexual side effects. We list Lexapro as one exact, consistent option among these related medicines, so that anyone comparing therapeutic alternatives can weigh strength availability, package size, and general profile before discussing the right choice with a prescriber.
