From the Guidelines
Luvox (fluvoxamine) is effective for treating panic disorder, as evidenced by its anxiolytic properties and ability to increase serotonin levels in the brain, which helps regulate mood and anxiety 1.
Key Points to Consider
- Luvox is a selective serotonin reuptake inhibitor (SSRI) that has been shown to be effective in treating anxiety disorders, including panic disorder.
- The typical starting dose for panic disorder is 50mg once daily, usually at bedtime, and can be gradually increased to 100-300mg daily as needed and tolerated 1.
- Common side effects of Luvox include nausea, headache, insomnia, and sexual dysfunction, which often improve with time.
- Patients should take Luvox regularly, even after feeling better, and should not stop abruptly as this can cause withdrawal symptoms.
- Treatment typically continues for at least 6-12 months after symptoms improve.
- Luvox may interact with several medications, including tizanidine, thioridazine, and MAOIs, so patients should inform their doctor about all medications they're taking 1.
Important Considerations
- The full therapeutic effect of Luvox may take 4-6 weeks to develop.
- Close monitoring for suicidality is recommended, especially in the first months of treatment and following dosage adjustments 1.
- Behavioral activation/agitation, mania/hypomania, and serotonin syndrome are potential risks associated with Luvox treatment, and patients should be educated about these risks and monitored closely 1.
Dosage and Administration
- The dosage of Luvox should be slowly up-titrated to avoid unintentionally exceeding the optimal medication dose 1.
- Youths may require twice-daily dosing, especially at low doses of sertraline and at any dose of fluvoxamine 1.
From the Research
Effectiveness of Luvox (Fluvoxamine) in Treating Panic Disorder
- Fluvoxamine has been shown to be effective in treating panic disorder, with studies indicating that it is as effective as imipramine in reducing symptoms of panic disorder 2.
- In a randomized, double-blind trial, fluvoxamine (≤ 300 mg/day) for 6 to 8 weeks was found to be significantly more effective than placebo in treating panic disorder 2.
- The efficacy of fluvoxamine in treating panic disorder has also been demonstrated in other studies, with improvements in symptoms observed in patients with panic disorder 3, 4.
- Fluvoxamine is generally well tolerated, with a low risk of suicidal behavior, sexual dysfunction, and withdrawal syndrome, making it a viable treatment option for panic disorder 2, 3.
Comparison with Other Treatments
- Fluvoxamine has been compared to other SSRIs, such as paroxetine and citalopram, and has been found to have similar efficacy in treating anxiety disorders, including panic disorder 2.
- However, direct comparisons between fluvoxamine and other pharmacological agents are limited, and further studies are needed to assess the relative efficacy and tolerability of different treatments for panic disorder 2, 5, 6.
Pharmacokinetic Properties
- Fluvoxamine has a high tolerability and safety profile, making it a suitable treatment option for panic disorder, but its interactions with the CYP450 enzymatic system may limit its use in certain patient populations 4.
- The pharmacokinetic properties of fluvoxamine have been extensively studied, and its implications for the treatment of anxiety disorders, including panic disorder, have been reviewed 4.
