100 Migraine Drugs, A to Z: fluvoxamine

Fluvoxamine (Luvox) is one of the drugs in the selective serotonin reuptake inhibitor (SSRI) class. Unlike other SSRIs, which are approved for the treatment of anxiety and depression, it is approved for the treatment of obsessive-compulsive disorder (OCD), although OCD is often accompanied by anxiety and depression. Fluvoxamine does relieve anxiety and depression as well, but it has been mostly promoted and used for the treatment of OCD.

The SSRIs are not very effective for the prevention of migraines, but a single double-blind study involving 64 patients showed that fluvoxamine is as good as amitriptyline for the prevention of migraines with fewer side effects. It may be best suited for migraine patients who also suffer from OCD, but I would not prescribe it for migraines without OCD.

Fluvoxamine may have more side effects than other SSRIs, such as fluoxetine (Prozac). Potential side effects of fluvoxamine is similar to those of other SSRIs and include nausea, insomnia, somnolence, headache (most drugs have headache as a potential side effect), decreased libido, nervousness, and dizziness. All antidepressants can also increase the risk of suicide.
