Escitalopram is a selective serotonin reuptake inhibitor (SSRI) used to treat several mood and anxiety disorders. This article covers escitalopram, available as a generic medication and marketed under brand names such as Lexapro, Cipralex, and others. It is supplied as oral pills in strengths of 5 mg, 10 mg, and 20 mg. In Hong Kong, escitalopram is a prescription-only medicine regulated by the Pharmacy and Poisons Board.
Escitalopram increases the amount of serotonin-a neurotransmitter involved in mood regulation-in the brain. It does this by blocking the serotonin transporter protein, which normally removes serotonin from the synaptic gap. By inhibiting re-uptake, more serotonin remains available to bind to post-synaptic receptors, helping to stabilize mood and reduce anxiety.
Escitalopram is approved by the Hong Kong Pharmacy and Poisons Board for the following indications:
It is typically prescribed to adults, although geriatric dosing may be adjusted based on renal function and tolerability.
These uses are not formally approved by Hong Kong regulators. Off-label use requires medical supervision and individualized risk assessment.
These are generally mild and often improve within the first few weeks of therapy.
Patients should disclose all prescription drugs, over-the-counter products, supplements, and herbal preparations before starting escitalopram.
Standard dosing:
Initiate with 5 mg once daily for the first week (especially in elderly or sensitive patients).
Increase to 10 mg daily based on clinical response and tolerability.
Maximum recommended dose is 20 mg daily.
Administration:
Swallow the pill whole with or without food.
Consistency in taking time each day helps maintain stable plasma levels.
Missed dose:
Take the missed dose as soon as remembered unless it is near the time of the next scheduled dose. Do not double the dose.
Overdose:
Symptoms may include nausea, vomiting, dizziness, and cardiac arrhythmias. Seek emergency medical attention; supportive care is the mainstay of treatment.
Discontinuation:
Abrupt stopping can lead to discontinuation syndrome (e.g., dizziness, sensory disturbances). Taper gradually under medical guidance, typically reducing by 5-10 mg every 1-2 weeks.

Weight fluctuations are reported with many SSRIs. Some patients experience mild weight gain, while others notice no change or slight weight loss. Monitoring weight during treatment is advisable.
Patients often notice improvement in symptoms within 1-2 weeks, but the full therapeutic effect may require 4-6 weeks of consistent dosing.
Escitalopram does not reduce the effectiveness of hormonal contraceptives, and the combination is generally considered safe.
Common 5 mg tablets may have the imprint “E5” or “ES5”; 10 mg tablets often bear “E10” or “ES10”; 20 mg tablets are frequently marked “E20” or “ES20.” Imprints can vary by manufacturer.
Standard workplace drug screens typically do not target SSRIs, so escitalopram is unlikely to trigger a positive result.
Yes, provided you carry the medication in its original prescription label, a copy of the prescription, and keep it in your carry-on luggage. Some countries may require a doctor’s note; verify local regulations before travel.
While SSRIs are not first-line agents for chronic pain, some patients report modest improvement in pain-related mood symptoms. Discuss options with a clinician.
Escitalopram is the S-enantiomer of citalopram and may have a slightly favorable side-effect profile at lower doses, but efficacy is comparable across SSRIs. Choice depends on individual response and tolerability.
Transitioning should be supervised by a healthcare professional to minimize withdrawal or serotonin syndrome risk. A cross-taper schedule is often used.
Contact a healthcare provider for guidance. Generally, do not take a double dose; the provider may recommend restarting at a lower dose and adjusting the schedule.
