What Is Fluvoxamine Used For?

Fluvoxamine treats obsessive-compulsive disorder, which involves recurring unwanted thoughts and repetitive behaviors. An extended-release formulation is also used for social anxiety disorder. A clinician selects the formulation and dose based on the condition being treated.

How Does Fluvoxamine Work?

Fluvoxamine slows the reuptake of serotonin by nerve cells. This increases serotonin activity between those cells. Symptom improvement can take several weeks.

How Is Fluvoxamine Taken?

Fluvoxamine is taken by mouth as a tablet or extended-release capsule. Depending on the formulation and dose, it is taken once or twice daily. Swallow extended-release capsules whole and follow the prescribed schedule.

What Are Fluvoxamine Side Effects and Precautions?

Nausea, sleep changes, and sexual difficulties can occur. Some children, teenagers, and young adults taking antidepressants have an increased risk of suicidal thoughts, particularly early in treatment or after dose changes. Fluvoxamine has significant medicine interactions, so review all prescriptions, supplements, and nonprescription products with a clinician or pharmacist.
