Fluvoxamine Tablets (Faverin): Key Facts, Dosage & Side Effects

Fluvoxamine, marketed as Faverin, is a selective serotonin reuptake inhibitor (SSRI) antidepressant primarily used to treat obsessive-compulsive disorder (OCD) and major depressive episodes. It works by increasing serotonin levels in the brain, helping to alleviate symptoms of these conditions.

About fluvoxamine tablets

Fluvoxamine tablets, commonly known by the brand name

Faverin

, belong to the class of medications called selective serotonin reuptake inhibitors (SSRIs). These drugs are designed to balance serotonin, a key neurotransmitter in the brain linked to mood regulation. Faverin is particularly effective for managing

obsessive-compulsive disorder (OCD)

, where individuals experience intrusive thoughts (obsessions) and repetitive behaviors (compulsions). It is also indicated for treating

depression

, specifically major depressive episodes.

Unlike some other SSRIs, fluvoxamine was developed with a strong focus on OCD treatment and has been in clinical use since the 1980s, with millions of patients treated worldwide. It is available in 50 mg and 100 mg film-coated tablets. The medication helps reduce the frequency and intensity of OCD symptoms and lifts depressive moods over time, typically showing benefits after 2-4 weeks of consistent use.

About obsessive-compulsive disorder (OCD)

**Obsessive-compulsive disorder (OCD)** is a mental health condition characterized by persistent, uncontrollable thoughts (obsessions) that lead to repetitive behaviors or mental acts (compulsions) aimed at reducing anxiety. Examples include excessive cleaning, checking locks repeatedly, or intrusive fears of harm. OCD affects about 1-2% of the population and can significantly impair daily life.

Fluvoxamine is FDA-approved for OCD in adults and children aged 8 and older. It helps by modulating serotonin pathways, reducing the urge to perform compulsions. Studies show it retains efficacy for at least one year with continued use.

About depression

**Depression**, or major depressive disorder, involves persistent sadness, loss of interest, fatigue, and changes in sleep or appetite. Fluvoxamine treats major depressive episodes by enhancing serotonin activity, which improves mood and energy levels. Treatment is typically continued for at least 6 months after symptom relief to prevent relapse.

In many countries like the UK, Australia, and Japan, it is commonly prescribed for depression alongside OCD.

Fluvoxamine tablets: the basics

Faverin comes in film-coated tablets of 50 mg and 100 mg strengths. Swallow whole with water, with or without food. For OCD, initial doses start low to minimize side effects, then titrate up.

How does it work?

Fluvoxamine selectively inhibits the reuptake of serotonin at neuronal membranes, increasing its availability in the synaptic cleft. This enhances serotonin’s mood-stabilizing effects. It may also influence norepinephrine receptors with chronic use.

Dosage

Dosage varies by condition, age, and response. Always follow your doctor’s prescription.

Condition	Adults	Children/Adolescents (8-17 years, OCD only)
OCD	Initial: 50 mg once daily at bedtime; max 300 mg/day	Initial: 25 mg once daily at bedtime; max 200-300 mg/day
Depression	Initial: 50-100 mg/day; max 300 mg/day	Not typically approved

Divide doses over 100 mg. Extended-release capsules (Luvox CR) start at 100 mg at bedtime.

How and when to take fluvoxamine tablets

• Take exactly as prescribed; do not exceed dose.
• Tablets can be taken morning or evening; bedtime dosing reduces daytime drowsiness.

Taking fluvoxamine tablets with other medicines and herbal supplements

Fluvoxamine interacts with many drugs due to CYP1A2/2D6 inhibition. Avoid:

• MAOIs (wait 2 weeks; reversible shorter).
• Other antidepressants, antipsychotics, opioids (serotonin syndrome risk).
• Warfarin, theophylline, clozapine (levels increased).
• Alcohol (worsens sedation).

Inform your doctor of all medications.
