From the Guidelines

To increase your Luvox (fluvoxamine) dosage from 150 mg, consult with your healthcare provider first, as they may recommend a gradual increase, often in 50 mg increments every 4-7 days, up to a maximum of 300 mg daily, as supported by the study on fluvoxamine dosage adjustments 1. When considering a dosage increase, it's essential to evaluate the potential benefits and risks, including the impact on morbidity, mortality, and quality of life.

  • The standard therapeutic range for Luvox is up to 300 mg daily, and increases are typically done gradually to minimize side effects.
  • Your healthcare provider will assess your individual situation, including your response to the current dosage and any side effects you're experiencing, before authorizing a dose change.
  • The study on fluvoxamine 1 provides evidence for the efficacy and safety of dosage adjustments, but it's crucial to prioritize caution and follow the guidance of a healthcare professional.
  • Potential side effects of increasing the Luvox dosage include nausea, headache, insomnia, or increased anxiety, which may occur temporarily as your body adjusts to the new dose.
  • It's essential to monitor your symptoms and side effects closely and report any concerns to your healthcare provider, as they can help you manage any adverse effects and adjust your treatment plan as needed.
  • Severe side effects, such as confusion, severe dizziness, rapid heartbeat, or suicidal thoughts, require immediate medical attention.

From the FDA Drug Label

Patients in these trials were titrated to a total daily fluvoxamine maleate dose of 150 mg/day over the first two weeks of the trial, following which the dose was adjusted within a range of 100-300 mg/day (on a bid schedule), on the basis of response and tolerance

The dose of Luvox can be increased from 150 mg by adjusting the dose within a range of 100-300 mg/day on a bid schedule, based on response and tolerance 2.

  • The dose adjustment should be done cautiously and slowly, especially in elderly patients or those with hepatic dysfunction.
  • The maximum adult dose is 300 mg/day.
  • Dose adjustment in adolescents (up to the adult maximum dose of 300 mg) may be indicated to achieve therapeutic benefit 2.

From the Research

Increasing Dosage of Luvox from 150 mg

To increase the dosage of Luvox (fluvoxamine) from 150 mg, consider the following points:

  • The recommended daily dose of fluvoxamine for treating obsessive-compulsive disorder (OCD) and other anxiety disorders is between 100 to 300 mg/day 3.
  • A study found that a high daily dose (100-150 mg) of fluvoxamine showed a higher percentage of improvement (73.7%) compared to a low daily dose (50-75 mg) (47.1%) 4.
  • If a patient does not show improvement by the end of 6 weeks, the treatment regimen of fluvoxamine should be altered, which may include increasing the dosage 4.
  • However, there is no strong evidence to indicate that fluvoxamine is either superior or inferior to other antidepressants regarding response, remission, and tolerability 5.

Considerations for Increasing Dosage

When considering increasing the dosage of Luvox from 150 mg, keep in mind:

  • Fluvoxamine is generally well-tolerated, but gastrointestinal adverse effects, especially nausea, are commonly reported 3, 6, 5.
  • The tolerability profile of fluvoxamine appears to be more favorable than that of tricyclic antidepressants in terms of cardiotoxic and anticholinergic adverse effects, sedation, weight gain, and death from overdosage 6.
  • Differing side effect profiles were evident, especially with regard to gastrointestinal side effects of fluvoxamine when compared to other antidepressants 5.

Monitoring and Adjustment

It is essential to:

  • Monitor the patient's response to the increased dosage and adjust the treatment regimen as needed.
  • Be aware of potential side effects and take steps to mitigate them.
  • Consider the patient's individual needs and medical history when making decisions about increasing the dosage of Luvox.
