Prozac molecules. Computer artwork of molecules of the antidepressant drug Prozac (fluoxetine hydrochloride). Atoms, represented as spheres, are colour-coded: carbon (grey), hydrogen (white), fluorine (green), oxygen (red) and nitrogen (blue). Prozac inhibits the uptake of the chemical serotonin, a powerful brain chemical that is important in mood regulation. As well as depressive illnesses, Prozac is also used to treat other disorders, such as bulimia nervosa and obsessive-compulsive disorder. Antidepressant drugs usually take at least 10 days to have any beneficial effect.
