faqs
are you at a healthy weight?
before you consider whether to use any over-the-counter diet aid, find out if you really need to lose weight. a healthy weight is a weight that lowers your risk for health problems. for most people, body mass index (bmi) and waist size are good ways to tell if they are at a healthy weight.
if you practice healthy eating habits and are active enough to stay healthy, then weighing a few extra kilograms is not bad for your health unless you have other medical problems. on the other hand, dieting can be bad for your health. weight-loss diets almost never work, and they can cause many people to fall into an unhealthy cycle of losing and gaining weight. this is often called yo-yo dieting.
if you are thinking about losing weight, ask your doctor whether it's a good idea for you.
what are over-the-counter diet aids?
there are many products for weight loss that you can buy without a prescription at drugstores and supermarkets and over the internet. many of these have never been proved to work, and those that do work usually come with warnings.
what are the risks or side effects of over-the-counter diet aids?
long-term studies are the only way to tell if a medicine or natural health product works and is safe. and there are very few such studies of diet aids. but we know about the following risks:
- over-the-counter appetite suppressants shouldn't be used by people who have heart disease, high blood pressure, diabetes, kidney problems, thyroid problems, glaucoma, or depression.
- appetite suppressants are only intended for use for a short time (8 to 12 weeks). but staying at a healthy weight is a lifelong effort. it is costly and possibly dangerous to depend on these medicines to control your weight for long periods of time. if you are going to use these drugs to help you lose weight, be sure to also make healthy changes to your diet and get regular exercise.
- water-loss pills (diuretics, such as diurex water caplets) only get rid of water and do not reduce the amount of fat in your body. using water-loss pills to lose weight is not recommended and can be dangerous.
- many products contain 20 or more ingredients, so it's really hard to know how all the ingredients will interact with each other in your body and how they will interact with any other medicines or natural health products you are taking.
- you shouldn't take cough or cold medicines while you take some of these diet pills. they contain some of the same medicine, and you could get too much. ask your pharmacist if it's safe to take cold medicine with the diet pills you are taking.
health canada has banned the sale of ephedra (also known as ma huang) because of concerns about safety. the product has been linked to heart attacks, strokes, and some deaths.
it's wise to talk to your doctor before you take any over-the-counter diet aid. for more information, go to health canada's webpage on the safe use of weight-loss products at www.canada.ca/en/health-canada/services/drugs-medical-devices/safe-use-health-products-weight-loss.html.
why might your doctor recommend an over-the-counter diet aid?
your doctor is not likely to recommend that you use an over-the-counter diet aid in your efforts to reach a healthy weight and stay there. the best way to get to a healthy weight and stay there is to eat right and exercise regularly.
to be safe, always talk to your doctor before using any weight-loss product.
