Lexapro (Escitalopram) Tablets

Lexapro is the branded escitalopram tablet that many Australian prescribers use to treat depression and several anxiety-related conditions. We stock Lexapro as oral tablets in 5 mg, 10 mg and 20 mg strengths, in pack sizes ranging from smaller quantities up to 360 tablets, so our customers can match an order to what their prescriber has recommended. Escitalopram belongs to the selective serotonin reuptake inhibitor (SSRI) class and has an extensive evidence base for its established indications. This article explains how escitalopram works, what taking Lexapro involves day to day, and how it compares with generic escitalopram and other treatment options.

Understanding Lexapro (escitalopram)

Lexapro's active ingredient is escitalopram, supplied as a film-coated oral tablet taken by mouth. Escitalopram is the pharmacologically active S-enantiomer of citalopram and produces its therapeutic effects primarily by inhibiting serotonin reuptake. Its ATC code, N06AB10, places it firmly within the SSRI group, alongside sertraline, fluoxetine, paroxetine and citalopram itself. We offer Lexapro in three strengths - 5 mg, 10 mg and 20 mg - which allows a prescriber's chosen dose to be filled precisely, whether that means a lower starting dose or a higher maintenance dose.

Depression and anxiety: why treatment matters

Major depressive disorder and generalised anxiety are among the most common conditions seen in general practice, and both can significantly affect sleep, concentration, relationships and work. Left untreated, depressive and anxiety symptoms may persist or worsen, and recurrent episodes can have an increasing effect on daily life. Escitalopram is one of several SSRIs used as first-line pharmacological treatment for these conditions, usually alongside psychological therapy such as cognitive behavioural therapy.

How escitalopram works in the brain

Escitalopram selectively blocks the serotonin transporter (SERT) on nerve endings, reducing the reuptake of serotonin back into the presynaptic neuron. This leaves more serotonin available in the synaptic space to act on postsynaptic receptors. The immediate reuptake blockade happens within hours of the first dose, but the clinical antidepressant and anxiolytic effect builds gradually as serotonin receptors and downstream signalling pathways adapt over several weeks. This delayed onset is one reason escitalopram is taken continuously rather than on an as-needed basis.

Evidence behind escitalopram

Escitalopram has been studied in numerous randomised, placebo-controlled trials for major depressive disorder, generalised anxiety disorder, panic disorder, social anxiety disorder and obsessive-compulsive disorder, with benefits generally assessed over several weeks of treatment. A widely cited 2018 network meta-analysis of 21 antidepressants, led by Cipriani and colleagues and published in The Lancet, ranked escitalopram among the more effective and better-tolerated options across head-to-head comparisons. Escitalopram is commonly used at a lower numerical milligram dose than citalopram because it is the S-enantiomer responsible for serotonin-reuptake inhibition. The milligram amounts of the two medicines should not be compared directly, however, and individual tolerability can still vary.

Ingredients and tablet formulation

Each Lexapro tablet contains escitalopram (as escitalopram oxalate) together with standard tableting excipients such as microcrystalline cellulose, talc and a film coating that aids swallowing and protects the tablet from moisture. The tablets are designed for consistent, once-daily oral dosing, and some strengths are manufactured with a score line that can assist a prescriber in adjusting a dose, although any change to a supplied dose should follow medical advice rather than informal splitting.

Established uses

Escitalopram is established for the treatment of major depressive disorder in adults and is also used for generalised anxiety disorder, panic disorder, social anxiety disorder and, in some regulatory settings, obsessive-compulsive disorder. Prescribers choose escitalopram based on symptom pattern, prior response to other antidepressants, tolerability considerations and any coexisting medical conditions.

Strengths, forms and general dosing principles

Lexapro tablets are supplied in 5 mg, 10 mg and 20 mg strengths, and we offer each strength in pack sizes from 10 up to 360 tablets to suit different treatment lengths. As general medicine information rather than an individual recommendation, treatment for depression and most anxiety disorders in adults commonly starts at 10 mg once daily, with some prescribers beginning at 5 mg in people who are more sensitive to SSRI side effects. Depending on the indication, response and tolerability, the dose may be increased to 20 mg daily, which is generally the maximum recommended adult dose. Older adults and people with hepatic impairment are commonly started at 5 mg daily and limited to a maximum of 10 mg daily. Escitalopram can be taken with or without food, at a similar time each day, and effects on mood and anxiety typically build gradually over two to four weeks, with fuller benefit sometimes taking six to eight weeks to appear.

Elimination and half-life

Escitalopram is metabolised mainly in the liver, principally via the CYP2C19 enzyme with smaller contributions from CYP3A4 and CYP2D6, and escitalopram and its metabolites are eliminated partly through the kidneys. Its elimination half-life is approximately 27 to 32 hours in adults with normal liver function, which supports once-daily dosing and means steady blood levels are usually reached after about one week of consistent use. People with reduced liver function, older adults, or those taking strong CYP2C19 inhibitors may clear escitalopram more slowly, which is one reason dose adjustments are sometimes made in these groups.

Important safety information

Escitalopram carries the safety considerations typical of SSRIs. Serotonin syndrome is a rare but serious risk, particularly when escitalopram is combined with other serotonergic medicines. Antidepressants, including escitalopram, are associated with a risk of new or worsening suicidal thoughts and behaviour, particularly in children, adolescents and young adults and during the first weeks of treatment or after a dose change, so close monitoring during these periods is important. Escitalopram can also cause dose-related QT interval prolongation, hyponatraemia, particularly in older adults, and discontinuation symptoms if the medicine is stopped abruptly rather than tapered under medical guidance.

Accessing Lexapro through our pharmacy

Escitalopram is classified as a Schedule 4 prescription-only medicine in Australia, meaning it is legally a prescription medicine at the national regulatory level. Separately, our own ordering process does not require you to upload a prescription document before we accept your order, so you can arrange your Lexapro tablets through us without that extra step, while still being encouraged to use the medicine as directed by your prescriber. Escitalopram tablets may also be subsidised for eligible patients and indications under Australia's Pharmaceutical Benefits Scheme when dispensed through that pathway, though PBS subsidy depends on the specific prescription and eligibility criteria rather than on how a customer chooses to order. We've supported Australian customers since 2018, and our pharmacist-backed team is available 24/7 by email and online chat if you have questions about your order, dosage schedule, or general use of escitalopram.

Who should avoid escitalopram

Escitalopram should not be used by anyone with a known hypersensitivity to escitalopram or any tablet ingredient. It is contraindicated in combination with monoamine oxidase inhibitors (MAOIs) because of the risk of serotonin syndrome. Escitalopram should generally not be started until 14 days after an irreversible MAOI has been stopped, and an MAOI should not be started until at least seven days after escitalopram has been stopped. It should also be avoided in people with congenital long QT syndrome or in combination with other medicines known to significantly prolong the QT interval, such as pimozide. Escitalopram is not recommended for children and adolescents under 18 years, given evidence from paediatric antidepressant trials of increased suicide-related thinking and behaviour alongside limited efficacy data in this age group. During pregnancy, escitalopram is classified as Category C; its use requires an individual risk-benefit discussion because of possible neonatal withdrawal symptoms or, rarely, persistent pulmonary hypertension of the newborn when used later in pregnancy. Because escitalopram passes into breast milk, Australian product information advises that breastfeeding generally should not continue during treatment, with continuation considered only after a prescriber's assessment and close observation of the infant.

Interactions with other medicines

Escitalopram can interact meaningfully with several other medicine groups, so it's worth reviewing anything else you take alongside it with your prescriber or pharmacist. Combining it with MAOIs or other strongly serotonergic medicines raises the risk of serotonin syndrome; combining it with NSAIDs, aspirin or anticoagulants can increase bleeding risk; other QT-prolonging medicines add to cardiac risk; and strong CYP2C19 inhibitors, such as omeprazole, can raise escitalopram blood levels.

This kind of overview is a starting point rather than a complete list, and any new prescription or over-the-counter medicine, including herbal products such as St John's Wort, should be checked against your current escitalopram treatment.

Side effects and when to seek help

Common escitalopram side effects tend to be mild and often ease within the first couple of weeks as the body adjusts. These include nausea, dry mouth, sweating, sleep disturbance, fatigue, reduced appetite and sexual side effects such as delayed orgasm or reduced libido. Less common but more serious effects call for prompt medical attention, including symptoms of serotonin syndrome (agitation, high fever, rapid heartbeat, muscle rigidity or tremor), signs of an allergic reaction, unusual bruising or bleeding, a marked change in mood such as new or worsening suicidal thoughts, or fainting linked to an irregular heartbeat. If any of these serious symptoms occur, contact a doctor urgently or seek emergency care; our support team is also available around the clock if you need guidance on next steps regarding an order or general product information.

Overdose and accidental exposure

Escitalopram has a relatively wide margin of safety compared with older antidepressant classes, but an overdose can still cause dizziness, drowsiness, nausea, vomiting, tremor, a fast or irregular heartbeat, QT prolongation and, in severe cases, seizures. Mixed overdoses involving other medicines can be more severe, while alcohol may worsen drowsiness and impaired judgement. Anyone who has taken more than their prescribed dose, or who suspects a child has accidentally swallowed tablets, should contact the Poisons Information Centre on 13 11 26 or call 000 in an emergency, and should bring the tablet packaging when seeking medical care so the exact strength can be identified.

Storing your tablets

Lexapro tablets should be stored at 25°C, with brief excursions between 15°C and 30°C considered acceptable, kept in their original, tightly closed container away from moisture and out of reach of children. Avoid storing tablets in a bathroom cabinet or near a kitchen sink where humidity is higher, and dispose of any unused or expired tablets through a pharmacy return program rather than household rubbish or wastewater.

Weighing benefits and trade-offs

Escitalopram's main advantages are a well-established efficacy record, a once-daily dosing schedule, a relatively favourable tolerability profile compared with older antidepressant classes, and three tablet strengths that make gradual titration straightforward. The trade-offs include a delayed onset of full benefit, the possibility of sexual side effects or initial activation symptoms, and the need for gradual dose reduction rather than abrupt stopping. For people who do not respond fully to an SSRI alone, a prescriber may consider a different class, a combination approach, or, in some treatment-resistant cases, augmentation with an agent such as aripiprazole, sold under the brand Abilify, alongside continued escitalopram. These decisions depend heavily on individual history and response, which is why ongoing follow-up with a prescriber matters throughout treatment.

Generic escitalopram and other treatment options

Generic escitalopram tablets contain the same active ingredient and strength as Lexapro and are expected to provide the same therapeutic effect when they meet applicable quality and bioequivalence requirements. Switching between the original brand and an appropriate generic equivalent is generally considered clinically acceptable when guided by a prescriber or pharmacist. Other escitalopram brands exist in various markets under names such as Cipralex, though we specifically stock and supply Lexapro tablets. Within the SSRI class, citalopram, sertraline and fluoxetine work through a similar serotonin-reuptake mechanism but differ in half-life, interaction profile and side-effect pattern, while paroxetine, available as Paxil, tends to be more sedating and has a shorter half-life associated with more noticeable discontinuation symptoms. For people who don't respond adequately to an SSRI, prescribers sometimes move to a serotonin-noradrenaline reuptake inhibitor such as venlafaxine or duloxetine, or to a different mechanism entirely, such as bupropion. Because these medicines vary in onset, side-effect profile and monitoring needs, any change between escitalopram and an alternative should be guided by a prescriber rather than made independently.
