Citalopram: Uses, Dosage, Side Effects and More

Introduction: What is Citalopram?

Citalopram is a prescription medication primarily used to treat depression. It belongs to a class of drugs known as selective serotonin reuptake inhibitors (SSRIs). By increasing the levels of serotonin in the brain, Citalopram helps improve mood, relieve anxiety, and enhance overall emotional wellbeing. It is commonly prescribed for major depressive disorder and is recognized for its effectiveness and relatively favorable side effect profile.

Uses of Citalopram

Citalopram is primarily approved for the treatment of major depressive disorder (MDD) in adults. It may also be used off-label for various conditions, including:

• Generalized anxiety disorder (GAD)
• Panic disorder
• Obsessive-compulsive disorder (OCD)
• Social anxiety disorder
• Posttraumatic stress disorder (PTSD)

The medication is often chosen for its ability to alleviate symptoms of depression and anxiety, making it a versatile option in mental health treatment.

How It Works

Citalopram works by selectively inhibiting the reuptake of serotonin, a neurotransmitter that plays a crucial role in mood regulation. In simpler terms, it helps keep serotonin levels higher in the brain, which can lead to improved mood and reduced feelings of anxiety. By preventing serotonin from being reabsorbed too quickly, Citalopram allows for more serotonin to be available to transmit signals between nerve cells, contributing to a more balanced emotional state.

Dosage and Administration

The standard dosage of Citalopram varies based on the individual's needs and the condition being treated.

• Adults: The typical starting dose is 20 mg once daily, which may be increased to a maximum of 40 mg per day based on the doctor's recommendation and the patient's response.
• Pediatric Patients: For children aged 12 to 17, the starting dose is usually 10 mg once daily, which can be increased to a maximum of 40 mg per day.

Citalopram is available in tablet form and is taken orally, with or without food. It is important to take the medication at the same time each day to maintain consistent levels in the bloodstream.

Side Effects of Citalopram

Like all medications, Citalopram can cause side effects. Common side effects include:
