Generic Celexa Information

Introduction

Celexa is an antidepressant medication marketed in the United Kingdom for the treatment of depressive disorders. Its active ingredient is citalopram, a selective serotonin re‑uptake inhibitor (SSRI) that increases the availability of serotonin in the central nervous system. Celexa is produced by Forest Laboratories (the original brand developer) and belongs to the antidepressant group of therapeutic agents. In addition to major depressive disorder, the drug is also recognised for off‑label use in anxiety‑related conditions when clinically appropriate.

What is Celexa?

Celexa is a tablet formulation that contains the active compound citalopram (20 mg, 40 mg, or 60 mg per tablet). It is classified as a selective serotonin re‑uptake inhibitor (SSRI) and was first introduced in the early 199s as a treatment for depression. Forest Laboratories, a subsidiary of Otsuka Pharmaceutical Co., developed the brand‑name product; generic equivalents of citalopram are also available from multiple manufacturers.

How Celexa Works

Citalopram inhibits the re‑absorption (re‑uptake) of serotonin by presynaptic neurons, thereby increasing synaptic concentrations of this neurotransmitter. Elevated serotonin levels improve mood, reduce anxiety, and modify pain perception. The drug reaches steady‑state plasma concentrations after 5–7 days of once‑daily dosing; therapeutic effects on mood typically emerge within 2–4 weeks, reflecting the time required for neuronal adaptation and downstream signalling changes. Citalopram is metabolised primarily by hepatic CYP2C19 and CYP3A4 isoenzymes and has a terminal half‑life of approximately 35 hours, allowing once‑daily dosing.

Conditions Treated with Celexa

Celexa’s efficacy is supported by multiple randomised controlled trials, including large‑scale meta‑analyses (e.g., Cipriani et al., 2018) that rank citalopram among the first‑line SSRIs for depressive illness.

Suitable Candidates for Celexa Treatment

Celexa is appropriate for adult patients (≥ 18 years) who have been diagnosed with major depressive disorder according to DSM‑5 or ICD‑10 criteria and who can tolerate SSRI therapy. Recommended scenarios include:

• First‑line therapy for individuals with moderate to severe depression, especially when comorbid anxiety is present.
• Patients who have previously responded to citalopram or similar SSRIs, indicating a favourable risk‑benefit balance.

Contra‑indications or cautionary situations include:

• Current use of monoamine oxidase inhibitors (MAOIs) or other serotonergic agents (e.g., tramadol, triptans) due to serotonin syndrome risk.
• Significant hepatic impairment, as metabolism relies on CYP2C19/3A4; dose adjustment may be required.
• Pregnancy or lactation without specialist supervision, because SSRI exposure carries potential infant risks.

Clinicians should evaluate cardiovascular history because high‑dose citalopram (> 60 mg) may prolong QT interval.

Risks, Side Effects, and Interactions

Common adverse events

• Nausea or gastrointestinal upset (up to 30 % of users).
• Insomnia or somnolence (variable).
• Dry mouth, increased sweating, or headaches.

These events are usually mild and resolve within 1–2 weeks of continued therapy.

Rare adverse events

• Hyponatraemia, particularly in older females or those on diuretics.
• Sexual dysfunction (loss of libido, erectile dysfunction, orgasmic delay).

Serious adverse events

• Serotonin syndrome: agitation, hyperthermia, tremor, diarrhoea; may be life‑threatening when combined with other serotonergic drugs.
• QT prolongation: rare at doses > 60 mg; requires ECG monitoring in high‑risk patients.
• Severe allergic reactions: angio‑edema, rash, urticaria, anaphylaxis.

Clinically relevant drug–drug interactions

Patients should disclose all current medications, including over‑the‑counter products and herbal supplements.

Practical Use: Dosing, Missed Dose, Overdose

Standard dosing (adults)

The dose may be increased after 1 week if tolerated and if the therapeutic response is insufficient. Dose adjustments are required in hepatic insufficiency or in patients aged ≥ 65 years.

Missed dose

If a dose is forgotten, patients should take it as soon as remembered unless the next scheduled dose is within 2 hours; in that case, they should skip the missed dose and resume the regular schedule. Doubling the dose to compensate is unsafe.

Overdose

Acute ingestion of > 200 mg may result in toxicity. Immediate actions include:

• Call the UK National Poisons Information Service (NPI H) at 30 000 900.
• Present to the nearest Accident & Emergency department, especially if symptoms such as seizures, arrhythmia, or prolonged QT interval occur.

Supportive care is primarily symptomatic; activated charcoal may be considered if presentation is early.

FAQ

• Is Celexa available in both brand‑name and generic forms in the UK?
  Yes. The brand‑name product is marketed as Celexa by Forest Laboratories, while generic citalopram tablets are produced by several independent manufacturers. Generic versions contain the same active ingredient and are typically less expensive.

• What is the most suitable storage condition for Celexa tablets?
  Celexa should be stored at a controlled room temperature (15 °C – 25 °C), protected from moisture, direct sunlight, and heat. Storing in a bathroom cabinet is discouraged because humidity can degrade the tablets over time.

• Do tablet colour and shape differ between UK and overseas batches?
  The UK‑approved Celexa tablets are round, bicolour (pink and white) with the imprint “CELEXA 20”. Some overseas generic versions may appear white, oval, and carry a different imprint. Visual differences do not affect potency when supplied by a licensed source.

• Can I travel with Celexa on an international flight?
  When travelling, keep the medication in its original packaging, carry a copy of the prescription, and store it in a carry‑on bag to avoid temperature extremes in luggage holds. UK customs permits personal import of a three‑month supply for personal use.

• Is there a known interaction between Celexa and over‑the‑counter cough medicines?
  Many cough syrups contain dextromethorphan, a serotonergic agent that can increase the risk of serotonin syndrome when combined with SSRIs. Patients should therefore avoid or consult a pharmacist before using such products while on Celexa.

• How does Celexa differ pharmacokinetically from other SSRIs such as fluoxetine?
  Citalopram has a comparatively linear pharmacokinetic profile with a half‑life of ~35 hours, whereas fluoxetine’s half‑life extends beyond 2 weeks, leading to longer steady‑state accumulation. Citalopram’s metabolism relies more heavily on CYP2C19, making it susceptible to drug interactions with inhibitors of that pathway.

• What are the UK regulations governing personal import of Celexa?
  Under the UK Human Medicines Regulations, individuals may import up to a three‑month supply of a medication for personal use, provided they possess a valid prescription and the product complies with UK safety standards. Our online pharmacy ensures all shipments meet these criteria.

• Are there specific warnings for Celexa use in patients of Asian descent?
  Some studies suggest a higher incidence of citalopram-induced QT prolongation in East Asian populations, likely related to genetic variations in CYP2C19. Clinicians often initiate therapy at a lower dose (10‑15 mg) and monitor ECG more closely in these patients.

• What clinical trial data supported the approval of Celexa in the UK?
  The pivotal double‑blind, placebo‑controlled study by Davidson et al. (1996) demonstrated a statistically significant reduction in Hamilton Rating Scale for Depression scores with Celexa 20 mg versus placebo, leading to its approval by the Medicines and Healthcare products Regulatory Agency (MHRA).

• Does Celexa contain any excipients that may trigger allergies?
  In the UK formulation, inactive ingredients include lactose, magnesium stearate, and microcrystalline cellulose. Patients with lactose intolerance or known hypersensitivity to these excipients should discuss alternatives with their prescriber.

• Can Celexa be detected in standard drug‑testing panels?
  Routine workplace drug tests typically screen for illicit substances and do not include SSRIs. However, therapeutic drug monitoring (TDM) for citalopram can be performed using high‑performance liquid chromatography (HPLC) if clinically indicated.
