Why is Luvox prescribed?

Fluvoxamine is prescribed for obsessive-compulsive disorder. An obsession is marked by continual, unwanted thoughts that prevent proper functioning in everyday living. Compulsive behavior is typified by ritualistic actions such as repetitious washing, repeating certain phrases, completing steps in a process over and over, counting and recounting, checking and rechecking to make sure that something has not been forgotten, excessive neatness, and hoarding of useless items.

You should also avoid taking fluvoxamine within 14 days of taking any antidepressant drug classified as an MAO inhibitor, including Nardil and Parnate.
