Additional Considerations

• Take this active ingredient once daily, with or without food, at a consistent time, preferably in the morning or evening.
• Avoid abrupt discontinuation to prevent withdrawal symptoms.

How to Use Escitalopram

Administration:

Oral: Swallow tablets whole or mix solution with water, taken once daily.

Take with or without food, using a calibrated device for solution.

Timing: Use at a consistent time to maintain steady levels.

Monitoring: Watch for agitation, suicidal thoughts, or signs of serotonin syndrome (e.g., tremor).

Additional Tips:

• Store at 20–25°C (68–77°F), protecting from moisture and light.
• Keep out of reach of children due to overdose risk.
• Report severe mood changes, seizures, or signs of allergic reactions immediately.

Contraindications for Escitalopram

Hypersensitivity: Patients with a known allergy to Escitalopram or other SSRIs.

MAOI Use: Avoid within 14 days of MAOI therapy due to serotonin syndrome risk.

Pimozide: Contraindicated due to QT prolongation risk.

Severe Hepatic Impairment: Contraindicated in Child-Pugh Class C.

Uncontrolled Bipolar Disorder: Avoid due to mania risk.

Warnings & Precautions for Escitalopram

General Warnings

Suicidal Thoughts: Increased risk in adolescents and young adults; monitor closely.

Serotonin Syndrome: Risk with other serotonergic drugs; watch for agitation or fever.

QT Prolongation: Risk of arrhythmias; monitor ECG if at risk.

Bleeding Risk: Increased with NSAIDs or anticoagulants; assess bleeding.

Hyponatremia: Risk in elderly or dehydrated patients; monitor sodium levels.

Additional Warnings

Seizure Risk: Increased in patients with seizure history; discontinue if seizures occur.

Angle-Closure Glaucoma: Risk with untreated narrow angles; assess eyes.

Mania/Hypomania: Risk in bipolar patients; screen history.

Withdrawal Symptoms: Risk with abrupt cessation; taper gradually.

Hypersensitivity Reactions: Rare anaphylaxis; stop if severe.

Use in Specific Populations

Pregnancy: Category C; use with caution and monitoring.

Breastfeeding: Use caution; monitor infant for effects.

Elderly: Higher risk of side effects; start with lower doses.

Adolescents: Safe with close supervision.

Renal/Hepatic Impairment: Adjust or avoid in severe cases.

Additional Precautions

Overdose and Management of Escitalopram

Overdose Symptoms

• Drowsiness, nausea, or tremor.

Immediate Actions

Contact the Medical Team: Seek immediate medical help.

Supportive Care: Monitor vital signs, provide IV fluids, and manage seizures if needed.

Specific Treatment: No specific antidote; use benzodiazepines for agitation or serotonin syndrome.

Monitor: Check ECG, serotonin levels, and mental status for 24–48 hours.
