Citanew Tablet Uses, Dosage and Side Effects in Pakistan

What Is Citanew?

Citanew is a Pakistani brand of escitalopram, a selective serotonin reuptake inhibitor (SSRI) — one of the most widely prescribed classes of antidepressants in the world. Escitalopram is the active (S-) enantiomer of citalopram and is considered the most selective of all SSRIs, meaning it acts very specifically on the serotonin system with relatively few off-target effects. This selectivity is part of why it is generally well tolerated.

In Pakistan, Citanew is commonly prescribed by psychiatrists and general physicians for depression and a range of anxiety disorders. It is important to understand that this is not a "quick fix" tablet like a painkiller — escitalopram gradually corrects the chemical imbalances underlying mood and anxiety disorders over a period of weeks, and it works best when combined with therapy, lifestyle changes and consistent follow-up.

How Does Escitalopram Work?

Serotonin is a neurotransmitter — a chemical messenger in the brain — that plays a key role in regulating mood, anxiety, sleep, appetite and a sense of well-being. In depression and anxiety disorders, the signalling of serotonin between nerve cells is thought to be reduced or dysregulated.

After serotonin is released by a nerve cell, it is normally reabsorbed (reuptaken) back into that cell, ending its signalling. Escitalopram (Citanew) selectively blocks the serotonin transporter, preventing this reuptake. As a result, more serotonin remains available in the synapse (the gap between nerve cells) to continue signalling. Over several weeks, this triggers gradual adaptive changes in brain circuits — which is why the antidepressant effect builds up slowly rather than appearing overnight.

Because escitalopram is so selective for serotonin and has minimal effect on other receptors (histamine, acetylcholine, noradrenaline), it tends to produce fewer of the sedating, weight-related and anticholinergic side effects associated with older antidepressants such as amitriptyline or imipramine.

Citanew Tablet Uses

1. Major Depressive Disorder (Depression)

Citanew is a first-line treatment for moderate to severe depression. Depression in Pakistan is significantly underdiagnosed and undertreated, partly due to stigma around mental health. Symptoms include persistent low mood, loss of interest or pleasure, disturbed sleep, low energy, poor concentration, feelings of guilt or worthlessness, and sometimes thoughts of self-harm. Escitalopram helps restore mood, sleep, energy and motivation over a period of weeks, helping patients return to normal functioning.

2. Generalised Anxiety Disorder (GAD)

GAD involves excessive, persistent and difficult-to-control worry about everyday matters, often accompanied by restlessness, muscle tension, fatigue, irritability and poor sleep. Escitalopram is one of the most effective and best-tolerated long-term treatments for GAD — a far safer option than benzodiazepines (such as alprazolam or bromazepam) for chronic anxiety, because it does not cause dependence.

3. Panic Disorder and Social Anxiety Disorder

For panic disorder — characterised by sudden, intense surges of fear with palpitations, breathlessness, chest tightness, dizziness and a sense of impending doom — Citanew reduces both the frequency and severity of panic attacks over time. It is also effective for social anxiety disorder, where intense fear of social situations and judgement leads to avoidance. In both conditions, the dose is often started low to avoid an initial increase in anxiety, then gradually increased.

4. Obsessive-Compulsive Disorder (OCD)

OCD involves intrusive, unwanted thoughts (obsessions) and repetitive behaviours or mental acts (compulsions) performed to reduce distress. SSRIs including escitalopram are a cornerstone of OCD treatment, although OCD often requires higher doses (up to 20 mg) and a longer trial (10–12 weeks) before full benefit is judged. Escitalopram is usually combined with cognitive behavioural therapy (CBT) for best results.

5. Mixed Anxiety-Depression in Pakistani Patients

In real-world practice in Pakistan, many patients present with overlapping symptoms of both depression and anxiety, often expressed through physical complaints (headaches, body aches, palpitations, "gas" and stomach upset) rather than purely emotional ones. Escitalopram's broad efficacy across both depression and anxiety makes it a practical, well-tolerated choice for these common mixed presentations.

Citanew Side Effects

Escitalopram is generally well tolerated. Many side effects are mild and improve after the first one to two weeks as the body adjusts.

Common:

• Nausea — most common early on; usually settles within 1–2 weeks; taking with food helps
• Headache — common in the first days of treatment
• Drowsiness or insomnia — escitalopram can cause either; adjusting the time of day you take it can help
• Increased anxiety or restlessness — may briefly worsen in the first 1–2 weeks before improving
• Dry mouth, sweating and reduced appetite — usually mild
• Sexual side effects — reduced libido or delayed orgasm; can persist and should be discussed with your doctor

Less Common / Serious — Seek Medical Help:

• Serotonin syndrome — agitation, confusion, fast heartbeat, high fever, muscle stiffness, tremor; a medical emergency, more likely when combined with other serotonergic drugs
• QT prolongation — an effect on heart rhythm at higher doses (above 20 mg) or with other QT-prolonging medicines; relevant for those with heart disease
• Hyponatraemia (low sodium) — more common in the elderly; causes confusion, weakness and headache
• Increased suicidal thoughts — particularly in young adults in the early weeks; requires urgent attention
• Unusual bleeding or bruising — SSRIs can slightly increase bleeding risk, especially with painkillers like ibuprofen or aspirin

Citanew (Escitalopram) vs Other Antidepressants

Who Should Be Cautious with Citanew

• People taking MAOIs — escitalopram must never be combined with MAOI antidepressants; a washout period of at least 14 days is required between them
• Heart rhythm problems (QT prolongation) — caution and dose limits apply; avoid doses above 20 mg and combinations with other QT-prolonging drugs
• Young adults under 25 — closer monitoring is needed in the early weeks due to a small risk of increased suicidal thoughts
• Bipolar disorder — an antidepressant alone can trigger mania; escitalopram should only be used with appropriate mood stabilisation
• Pregnancy and breastfeeding — decisions should be individualised with a doctor; untreated depression also carries risks, so do not stop on your own if pregnant
• Liver impairment and the elderly — lower doses are used

Drug Interactions

Escitalopram has several important interactions to be aware of:

• MAOIs (phenelzine, selegiline, linezolid) — contraindicated; risk of life-threatening serotonin syndrome
• Other serotonergic drugs (tramadol, other SSRIs/SNRIs, triptans for migraine, St John's Wort) — additive serotonin syndrome risk
• NSAIDs and aspirin — increased risk of gastrointestinal bleeding; use gastric protection if needed
• QT-prolonging drugs (some antibiotics, antipsychotics, anti-arrhythmics) — additive risk on heart rhythm
• Alcohol — best avoided; it can worsen mood and increase drowsiness
• Blood thinners (warfarin) — monitoring may be needed due to bleeding risk

Citanew vs Lexapro / Cipralex — Same Drug, Different Brands

A frequent question in Pakistan is whether Citanew is the same as Lexapro or Cipralex. The answer is yes — all three contain identical active ingredient: escitalopram. Lexapro and Cipralex are the original brands by Lundbeck, while Citanew is a more affordable Pakistani brand of the same molecule. At the same dose, they are clinically equivalent in efficacy and safety. The main practical difference is cost, with Citanew generally being significantly cheaper. Other escitalopram brands available in Pakistan are equally effective when taken at the equivalent dose.

Availability and Cost in Pakistan

Citanew and other escitalopram brands are widely available at pharmacies across Pakistan and should be purchased with a doctor's prescription. Pricing varies by strength and brand — a strip of Citanew typically costs in the range of roughly 150–400 PKR, while imported originator brands such as Lexapro and Cipralex cost more. Because treatment is usually continued for at least 6–12 months (and often longer for recurrent illness), the affordability of local brands like Citanew makes consistent, long-term treatment far more achievable for Pakistani patients.

Conclusion

Citanew (escitalopram) is one of the most effective and best-tolerated SSRI antidepressants available in Pakistan, used for depression, generalised anxiety disorder, panic disorder, social anxiety disorder and OCD. The two most important things to remember are that it takes 2–4 weeks to start working — so do not give up early — and that it must never be stopped abruptly, but tapered gradually to avoid discontinuation syndrome. It is not addictive and not a controlled substance, but it should always be taken under medical supervision, with close monitoring in the first month. Mental health conditions are real, treatable medical illnesses — seeking help is a sign of strength, not weakness. If you are struggling, talk to a qualified doctor.
