Diet pills are one option to assist in a weight loss effort. There are many diet pills available, and many do not require a doctor's prescription. These over-the-counter medications may contain all natural ingredients and other active ingredients. The supplements can cause side effects that range from mild to serious. Unlike prescription formulas, over-the-counter diet pills are not regulated by the FDA. Before taking any diet pills, consult with your doctor first.
Over The Counter Diet Pills
Common ingredients included in over the counter diet pills and supplements are hoodia, guar gum, green tea extract, chromium and bitter orange. It's important to remember that over-the-counter medications are not monitored by the FDA. According to Mayo Clinic internist Brent A. Bauer, M.D., there isn't any solid evidence that hoodia is effective.
Similarly, Mayo Clinic nutritionist Katherine Zeratsky warns that due to its stimulant-like effects, bitter orange poses serious health risks. The chemicals in bitter orange may speed up your heart rate and raise your blood pressure. It is always important to consult with your doctor before taking any herbal medications.
Phentermine
Phentermine is a common ingredient in prescription diet pills. It works by decreasing your appetite and is usually prescribed for a short time. The pill can become habit forming. Besides mild side effects like dry mouth, some serious health complications have also been associated with the medication, including heart palpitations and increased blood pressure. Anyone taking this prescription diet pill should ensure that all doctor appointments are kept.
Orlistat
Orlistat is a lipase inhibitor that is used in some prescription and over-the-counter diet pills. It is approved by the FDA. According to MedlinePlus, medications containing this ingredient work by blocking the absorption of some fats in the foods eaten as they move through the digestive system. Some medications can interact negatively with orlistat and side effects can include difficulty controlling bowel movements.
Caffeine
Caffeine is found in many diet pills, and according to Mayo Clinic nutritionist Katherine Zeratsky, theoretically, caffeine can suppress your appetite, burn calories and act as a diuretic which results in water weight loss. Significant or permanent weight loss is questionable, though. Additionally, because of its stimulant effects, use of caffeine can result in nervousness, insomnia, and other side effects.
