When considering using drugs to suppress appetite to help lose weight, the first thing to emphasize is that any weight loss drugs should be used under the guidance of a doctor, because they may bring side effects and health risks. The following are some common prescription drugs that may help lose weight by suppressing appetite： 1. **Phentermine**: This is a common weight loss drug and is an appetite suppressant. It reduces hunger by stimulating the central nervous system. It is usually used for short-term weight loss because it may be dependent. 2. **Orlistat**: Although it is not a drug that directly suppresses appetite, it helps to lose weight by preventing the absorption of fat. Usually used for long-term weight management. 3. **Liraglutide (Liraglutide)**: This is a GLP-1 receptor agonist, originally used to treat type 2 diabetes, but it is also approved for weight loss. It helps lose weight by increasing satiety and reducing appetite. 4. **Naltrexone/Bupropion (Naltrexone/Bupropion)**: This is a combination drug that reduces appetite by affecting the hunger and satiety centers in the brain. ### Important note： -**Consult a doctor**: Before starting any weight loss drugs, be sure to consult a doctor or a professional health care provider. They can recommend the most appropriate treatment plan based on your health status, weight goals, and potential risks. -**Lifestyle changes**: Drugs should usually be used in combination with a healthy diet and regular exercise to achieve the best results. Long-term successful weight loss usually depends on lifestyle changes. -**Side effects**: These drugs may cause side effects, such as headache, insomnia, nausea, constipation, etc. It is important to understand these potential risks and communicate with your doctor regularly. -**Mental health**: In the process of weight loss, mental health is equally important. If you feel anxiety, depression or other emotional problems, seek professional help in time. Finally, losing weight quickly is not always a healthy choice. Sustainable weight loss usually requires time and patience. It is recommended to achieve long-term weight management goals through a healthy diet, exercise and good habits.
