Celexa: Effective SSRI Treatment for Major Depressive Disorder
Celexa (citalopram hydrobromide) is a selective serotonin reuptake inhibitor (SSRI) antidepressant approved by the FDA for the treatment of major depressive disorder (MDD) in adults. As a well-established pharmacological intervention, it works by increasing serotonin levels in the brain, which helps improve mood, sleep, appetite, and energy levels. Its favorable side effect profile and once-daily dosing make it a commonly prescribed option in clinical practice for managing depressive symptoms.
Features
- Active ingredient: citalopram hydrobromide
- Available in 10 mg, 20 mg, and 40 mg oral tablets
- Also supplied as a liquid solution (10 mg/5 mL)
- Class: selective serotonin reuptake inhibitor (SSRI)
- Prescription-only medication
- Manufactured under strict pharmaceutical quality standards
Benefits
- Effectively reduces symptoms of major depressive disorder, including low mood and loss of interest
- Helps restore normal sleep patterns and improve energy levels
- Generally well-tolerated with a lower incidence of certain side effects compared to older antidepressants
- Simple once-daily dosing supports treatment adherence
- Non-sedating for most patients, allowing daytime functionality

Common use
Celexa is primarily indicated for the treatment of major depressive disorder (MDD) in adults. It may also be prescribed off-label for conditions such as generalized anxiety disorder (GAD), panic disorder, obsessive-compulsive disorder (OCD), and post-traumatic stress disorder (PTSD), though such uses should be carefully evaluated by a healthcare provider based on individual patient factors and clinical evidence.
Dosage and direction
The recommended starting dosage for Celexa is 20 mg once daily, with or without food. Depending on individual patient response and tolerability, the dosage may be increased to a maximum of 40 mg per day after a minimum of one week. Dosage adjustments should be made under medical supervision. For elderly patients or those with hepatic impairment, a maximum dose of 20 mg per day is recommended. Abrupt discontinuation should be avoided; instead, gradual tapering is advised under physician guidance to minimize withdrawal symptoms.
Precautions
- Monitor for worsening depression or emergence of suicidal thoughts, especially in children, adolescents, and young adults
- Use with caution in patients with a history of mania/hypomania or seizure disorders
- May cause hyponatremia; monitor sodium levels in at-risk patients (e.g., elderly, those on diuretics)
- Can prolong the QT interval; avoid use in patients with congenital long QT syndrome or those taking other QT-prolonging drugs
- Inform healthcare provider of all current medications and medical conditions before starting treatment
- Avoid alcohol during treatment
Contraindications
- Hypersensitivity to citalopram or any component of the formulation
- Use of monoamine oxidase inhibitors (MAOIs) concurrently or within 14 days of discontinuing Celexa; allow 14 days after stopping Celexa before starting an MAOI
- Patients with congenital long QT syndrome
- Coadministration with pimozide
Possible side effects
Common side effects may include:
- Nausea
- Dry mouth
- Increased sweating
- Sleepiness or insomnia
- Fatigue
Less common but serious side effects require immediate medical attention:
- Serotonin syndrome (agitation, hallucinations, fever, fast heart rate)
- Abnormal bleeding
- Angle-closure glaucoma
- Manic episodes
- Seizures
- QT prolongation
Drug interaction
Celexa may interact with:
- MAOIs (risk of serotonin syndrome)
- Other serotonergic drugs (tramadol, lithium, triptans, St. John’s wort)
- Drugs that prolong QT interval (e.g., antiarrhythmics, antipsychotics)
- NSAIDs, aspirin, or warfarin (increased bleeding risk)
- CYP2C19 inhibitors (e.g., omeprazole) may increase citalopram levels
- CYP3A4 inducers may decrease citalopram efficacy
Missed dose
If a dose is missed, take it as soon as remembered unless it is close to the time for the next dose. Do not double the dose to make up for a missed one. Maintain regular dosing schedule to ensure stable medication levels.
Overdose
Symptoms of overdose may include dizziness, sweating, nausea, vomiting, tremor, somnolence, and in rare cases, seizures or ECG changes. In suspected overdose, seek immediate medical attention or contact a poison control center. Treatment is supportive and may include activated charcoal, ECG monitoring, and symptomatic care.
Storage
Store at room temperature (20-25°C or 68-77°F), away from light and moisture. Keep out of reach of children and pets. Do not use after the expiration date printed on the packaging. Properly discard any unused medication.

Reviews
Clinical studies and patient reports indicate that Celexa is effective in reducing symptoms of depression for many individuals. Patients often note improvement in mood, motivation, and overall quality of life after several weeks of consistent use. Some report side effects such as initial nausea or sleep disturbances, which often diminish over time. Healthcare providers emphasize the importance of ongoing monitoring and adherence to prescribed treatment plans.
