Similarly diet drugs used in the 1930s, 1950s and 1960s, were also associated with complications.

Only two anti-obesity medications are currently approved by the FDA for long term use. One is ORLISTAT, which reduces intestinal fat absorption by inhibiting pancreatic enzyme called lipase. Diarrhea and incontinence of stools may be side-effects of this medicine.
The other is SIBUTRAMINE which acts on the brain to inhibit deactivation of some neurotransmitters therefore reducing the appetite. It works by making the person feel full and thereby decreases food intake. It may cause an increase in blood pressure and should not be used by people who are on a number of other medications, such as antidepressants.
