How can a sleep disorder be treated?

Sleep disorder is just like pain and mood. It depends on what might be causing sleep disturbance. Not all sleep disturbances need medications. The best way to take care of sleep disturbances is probably to figure out what is causing the sleep problems and getting that treated. However, sometimes it is difficult to figure out the underlying causes and in such case we tend to empirically treat sleep disturbances with medications. There are several medications which have been approved by the US-FDA - these include Zolpidem, Zalpelon, Ramelteon, and Eszopiclone. I suggest that you see a physician specializing in sleep medicine who can evaluate you further and then recommend treatment.
