Anorectic drugs are used to reduce appetite. These drugs do not reduce weight but act as an aid to controlling appetite while the patient complies with a strictly controlled diet. They are available in tablet and capsule form only.
Anorectics should not be used for long periods, as dependence can occur. Some are stimulants, which may cause insomnia if used in the evening, and are used illegally by long-distance drivers and other who wish to remain awake for long periods of time. They should not be mixed with alcohol, and their use during pregnancy is controversial.
Many drugs in this class have been removed from the market in recent years because of abuse, interactions and side effects.
