An appetite suppressant (commonly known as an anorectic or anorexigenic), Didrex was approved by the American Food and Drug Administration for use for weight management in obese people in 1960. As Didrex is chemically related to amphetamines (eg. Speed), it is classed as a schedule III controlled substance as it has a moderate potential for abuse. It works by stimulating your central nervous system (in the hypothalamus and limbic regions of the brain), increasing your blood pressure, which suppresses your appetite, creating a feeling of fullness. The amount of weight lost can be increased when this drug is used in combination with a low-calorie diet and regular exercise.
Dosage: Your doctor should determine the dose you should be taking, based on your weight loss needs. Ingested orally, Didrex can be taken as a single, sustained-release dose (75mg) either mid-morning or mid-afternoon. It can also be taken as regular tablets (25 or 50mg) and should be taken on an empty stomach one hour before meals. The maximum dose of this tablet that can be taken each day is 150mg. If you miss a dose, do not take a double dose – wait until it is time to take your next dose, and take that one as normal. These tablets also contain the following inactive ingredients: calcium stearate, cornstarch; ervthrosine sodium; FD 8 C yellow No. 61; lactose; providone; sorbitol.
