Step-by-step guideLuvox (Fluvoxamine) Withdrawal: Tapering the Forgotten SSRIFluvoxamine (Luvox) has one of the shortest half-lives of any SSRI, roughly 15 to 20 hours, which is why Luvox withdrawal often starts within a day or two of a missed or reduced dose. Most people who come off it too fast get dizziness, nausea, insomnia, and electrical "zap" sensa

Overview

Fluvoxamine is an SSRI primarily approved for obsessive-compulsive disorder (OCD). It is a potent inhibitor of CYP1A2 and CYP2C19 and also has sigma-1 receptor agonist activity, which may contribute to its anxiolytic properties.

Common Doses

25mg, 50mg, 100mg, 200mg

Formulations

Tablets: 25mg, 50mg, 100mg; Extended-release capsules (CR): 100mg, 150mg

Pregnancy

Category C (risk cannot be ruled out)

Mechanism of Action

Selective serotonin reuptake inhibitor (SSRI) that potently inhibits the serotonin transporter (SERT). Also acts as a sigma-1 receptor agonist, which may provide additional anti-anxiety and neuroprotective effects.

Taper Notes

Short half-life. CR formulation available. Tablets can be split for gradual reduction.

Hyperbolic Tapering Guidance

Shorter half-life than most SSRIs; slower taper pace recommended. Tablets can be dissolved in water for precise dosing.

Interactions & Safety

Drug Interactions

  • MAOIs — contraindicated (serotonin syndrome risk)
  • Thioridazine — contraindicated
  • Alosetron — contraindicated (CYP1A2 inhibition)

Food Interactions

  • No significant food effect on absorption
  • Caffeine levels may increase significantly due to CYP1A2 inhibition
  • Avoid alcohol during treatment

Contraindications

  • MAOIs within 14 days
  • Thioridazine
  • Alosetron

Toxicity

Serotonin syndrome with serotonergic combinations. Significant drug interactions due to CYP1A2 inhibition (e.g., with theophylline, clozapine, tizanidine).

Pharmacokinetics

ADME Profile

Absorption

Completely absorbed after oral administration. Bioavailability ~53% due to first-pass metabolism. Tmax 3–8 hours. Food does not significantly affect absorption.

Distribution

~25 L/kg

Metabolism

Extensively metabolized hepatically via CYP2D6 and CYP1A2. Potent inhibitor of CYP1A2 and CYP2C19, moderate inhibitor of CYP2C9 and CYP3A4. No active metabolites.

Elimination

Renal (~94% as metabolites, ~2% unchanged).

Protein Binding

~77–80%

Clearance

~1400 mL/min (apparent oral clearance)

The arithmetic of a proportional reduction

The Maudsley Deprescribing Guidelines and NICE NG222 describe reducing SSRI medications by a proportion of the previous dose rather than by a fixed amount, so each cut is smaller than the last. The table shows what that arithmetic produces at 10% per step, using 50 mg only as a worked example. How large each step is, how long it is held, and whether this pattern applies at all are decisions for the person and their prescriber.

Frequently asked questions about Luvox

What are the withdrawal symptoms of Luvox (fluvoxamine)?

Common withdrawal symptoms of Luvox (fluvoxamine) include: brain zaps, dizziness, nausea, insomnia, irritability. Symptom severity varies by individual, dose, and duration of use.

How should I taper off Luvox (fluvoxamine)?

Short half-life. CR formulation available. Tablets can be split for gradual reduction. Shorter half-life than most SSRIs; slower taper pace recommended. Tablets can be dissolved in water for precise dosing.

Can I stop Luvox cold turkey?

Stopping Luvox abruptly is not recommended. Its half-life is 15–22 hours, and the receptor adaptations built up during treatment do not reverse at that speed, so a sudden stop tends to produce the sharpest withdrawal. Prescribing guidance favours gradual, proportional reductions agreed with your prescriber.

How long does Luvox stay in your system?

Luvox (fluvoxamine) has a half-life of 15–22 hours. A drug is mostly cleared after about five half-lives, so Luvox is largely out of the body roughly 3 to 5 days after the last dose, longer in older adults or with liver or kidney impairment. Withdrawal symptoms often begin before the drug has fully cleared and continue after it has, because the adaptations the brain made during treatment reverse more slowly than the drug leaves the blood.
