Comments

Effective in the treatment of obsessive-compulsive disorder, generalized anxiety disorder, social anxiety disorder, panic disorder. Also used to treat depression and post-traumatic stress disorder

Children metabolize SSRIs more rapidly than adults and may require doses in the higher end of the dosage range. Lower fluvoxamine doses may be more effective in females than in males.

May take 4 weeks to see therapeutic effects.

Common adverse effects: headache, nausea, dry mouth, sweating, tremor and impaired sexual function (adolescents/adults).

Do not suddenly stop long-term treatment due to risk of discontinuation syndrome (flu-like symptoms, dizziness, "electric-shock" sensations). Recommend tapering dose by ~25%/week. See fluoxetine for more information.

Most sedating and nauseating of the SSRIs

Many CYP drug interactions (strong CYP 1A2 and CYP 2C19 inhibitor)
