Weight loss tablets

Having a well-balanced diet and exercising are essential for any weight loss treatment and for the prevention of weight gain. However, some individuals may also benefit from using prescription weight-loss drugs. Here, we will take a closer look at the pros and cons of these medications, their side effects, effectiveness and other important considerations.

What are prescription weight-loss drugs?

Prescription weight-loss drugs are medications prescribed to individuals who have been unable to lose weight through diet and exercise alone. These drugs are regulated by the FDA and require a prescription, issued by a healthcare professional.

They are recommended for people with a body mass index (BMI) greater than or equal to 30, indicating obesity, or a BMI greater than or equal to 27 with a weight-related medical problem such as type 2 diabetes, heart disease or high blood pressure.

How do prescription weight-loss drugs work?

Prescription weight-loss drugs work through a variety of mechanisms, some are appetite suppressants, while others prevent the absorption of dietary fat.

Bupropion-Naltrexone (Contrave)

The combination of the active ingredients, bupropion and naltrexone helps to reduce appetite and cravings, making it easier to maintain a calorie-restricted diet. Bupropion does carry a risk of suicidal thoughts and increased blood pressure, and therefore requires close monitoring.

Liraglutide (Saxenda)

Liraglutide, originally developed to manage diabetes is now approved for weight loss in people without diabetes. Liraglutide mimics GLP-1, which regulates appetite and helps control blood sugar levels by increasing feelings of fullness and reducing food intake. Side effects of liraglutide include nausea, vomiting, and pancreatitis.

Orlistat (Xenical, Alli)

Orlistat inhibits the absorption of dietary fat in the intestines by blocking an enzyme called lipase, which is responsible for breaking down body fat. This results in a portion of the consumed fat passing through the digestive system without being absorbed. Orlistat is available as Xenical, or over-the-counter, as Alli. Common side effects include oily stools, gas, and frequent bowel movements.

Phentermine-Topiramate (Qsymia)

Phentermine-topiramate suppresses appetite and increases feelings of fullness. Phentermine acts as a stimulant, helping to reduce appetite, while topiramate is an anticonvulsant that causes weight loss as a side effect. Side effects of phentermine-topiramate include increased heart rate, insomnia, and tingling in the hands and feet.

Semaglutide (Wegovy, Ozempic)

Semaglutide is another GLP-1 receptor agonist, initially developed to manage diabetes, but has subsequently shown significant weight-loss effects. Semaglutide regulates appetite and helps to reduce food intake. Semaglutide is available as a weekly injection. Side effects include nausea, diarrhoea, and headache.

Setmelanotide (Imcivree)

Setmelanotide is approved for use in children, 6 years of age and older, with obesity caused by specific genetic conditions. It helps to regulate hunger and fullness by targeting rare genetic disorders associated with extreme hunger. Side effects include skin irritation, nausea, and changes in skin pigmentation.

These medications should be used in combination with a weight-loss plan that includes a healthy diet and regular exercise. They should be used to enhance the effectiveness of lifestyle changes and not as a standalone solution for weight loss.

Effectiveness of prescription weight-loss drugs

Studies show that people who combine weight loss drugs with a reduced-calorie diet and increased physical activity can lose between 5 to 12 percent more weight than when using lifestyle changes alone.
