Escitalopram is a selective serotonin reuptake inhibitor used to treat major depressive disorder and generalized anxiety disorder.
Escitalopram belongs to a class of medicines called selective serotonin-reuptake inhibitors (SSRIs). It is used primarily to help balance mood-related chemicals in the brain. In Hong Kong, escitalopram is available both as the brand product Lexapro and as the generic name Escitalopram.
The two most common products containing this ingredient are Lexapro and Escitalopram tablets. Both are offered in several strengths, typically 5 mg, 10 mg and 20 mg, and are supplied as oral tablets that dissolve in the mouth before swallowing. While Lexapro is a branded version marketed by a multinational pharmaceutical company, escitalopram is the generic counterpart produced by a range of local and international manufacturers. These products are listed on the Hong Kong Department of Health’s medicines register and may be obtained with a prescription from a qualified health professional.
These uses reflect the conditions for which escitalopram is approved by the Hong Kong regulatory authorities. The drug works for a wide range of adults experiencing mood or anxiety-related symptoms, though individual treatment decisions are made by health professionals based on each person’s situation.
Escitalopram increases the amount of serotonin, a natural chemical messenger, available in the brain. By preventing the re-absorption of serotonin into nerve cells, it allows more of the substance to remain active, which can improve mood and lessen anxiety. Most people notice a gradual change after a few weeks, rather than an immediate effect. The medication does not act on other body systems directly, which helps keep its activity focused on emotional regulation.
These effects often lessen as the body adjusts to the medication and are generally short-lasting.
If any of these occur, seek immediate medical assistance.
Escitalopram can interact with other medicines that affect serotonin levels, such as other antidepressants, certain migraine treatments, and some herbal supplements like St John’s wort. Alcohol may enhance side effects such as drowsiness. Certain foods and drinks do not markedly affect escitalopram, but it is wise to avoid excessive caffeine if you notice heightened anxiety. For a full list of possible interactions, refer to the specific product information for Lexapro or the generic escitalopram tablet you are using.
