Losing weight can sometimes feel like an uphill battle, but with the help of weight loss medications, your journey can become a little easier. This comprehensive guide is here to give you a brief overview of the various types of weight loss medications that are currently available. From appetite suppressants to fat blockers and metabolism boosters, each medication works differently to help you shed those extra pounds. So, if you’re curious to know how these medications differ in their mechanisms and which one might be the right choice for you, read on to learn more.
1. Appetite suppressants
Appetite suppressants are a category of weight loss medications that work by reducing your food cravings and suppressing your appetite. These medications can help you feel full with smaller portions, making it easier to adhere to a reduced-calorie diet.
1.1 Phentermine
Phentermine is one of the most commonly prescribed appetite suppressants. It stimulates the release of certain chemicals in your brain that help control your appetite, making you feel less hungry. It is typically prescribed for short-term use in conjunction with a healthy diet and exercise.
1.2 Diethylpropion
Diethylpropion is another type of appetite suppressant that works by increasing levels of norepinephrine in your brain. This helps to reduce your appetite and promote weight loss. Like phentermine, diethylpropion is generally prescribed for short-term use.
1.3 Mazindol
Mazindol is a less commonly prescribed appetite suppressant that works by increasing the release of dopamine and norepinephrine in your brain. This can help decrease your appetite and assist in weight loss efforts. Mazindol is typically used for short-term treatment of obesity.
2. Fat absorption inhibitors
If you struggle with absorbing fat from your diet, fat absorption inhibitors may be an option to explore. These medications work by blocking certain enzymes in your digestive system that break down dietary fat, preventing its absorption by your body.
2.1 Orlistat
Orlistat is the most commonly used fat absorption inhibitor. It works by inhibiting the action of lipase, an enzyme that breaks down dietary fat. This prevents your body from absorbing some of the fat you consume, leading to reduced calorie intake and weight loss. Orlistat is typically taken with meals that contain fat.
3. Metabolism boosters
Metabolism boosters are weight loss medications that aim to increase your metabolic rate, helping you burn more calories throughout the day. By increasing your metabolism, these medications can assist in weight loss efforts.
3.1 Sibutramine
Sibutramine is a medication that affects the neurotransmitters in your brain, increasing their activity. This results in a boost to your metabolic rate and a reduction in your appetite. However, it’s important to note that sibutramine has been withdrawn from the market in several countries due to safety concerns, so it may not be readily available.
4. Thyroid hormone regulators
Thyroid hormone regulators are medications that help regulate the function of your thyroid gland, which plays a crucial role in metabolism. These medications can help normalize your thyroid hormone levels, potentially aiding in weight loss.
4.1 Liothyronine sodium
Liothyronine sodium is a synthetic form of a thyroid hormone known as triiodothyronine (T3). It can help increase your metabolic rate and promote weight loss in individuals with thyroid disorders. However, it should only be used under the supervision of a healthcare professional.
5. Serotonin and norepinephrine reuptake inhibitors
Serotonin and norepinephrine reuptake inhibitors (SNRIs) are medications commonly used to treat depression and anxiety. However, some SNRIs have also been found to be effective in promoting weight loss.
5.1 Bupropion/naltrexone
Bupropion/naltrexone is a combination medication that works by increasing the levels of certain neurotransmitters in your brain. This can help control your appetite and reduce food cravings. Bupropion/naltrexone is typically prescribed for adults with a body mass index (BMI) of 30 or higher and is used in conjunction with a reduced-calorie diet and increased physical activity.
6. Anti-seizure medications
Certain anti-seizure medications have been found to have weight loss effects and may be prescribed off-label for this purpose.
6.1 Topiramate
Topiramate is an anti-seizure medication that has shown some efficacy in promoting weight loss. Its exact mechanism of action in weight loss is not fully understood, but it is believed to affect appetite and energy expenditure. Topiramate can be used off-label for weight loss, but it should only be taken under the supervision of a healthcare professional.
7. Glucagon-like peptide-1 (GLP-1) receptor agonists
GLP-1 receptor agonists are a class of medications originally developed to treat type 2 diabetes. However, they have also been found to be effective in promoting weight loss.
7.1 Liraglutide
Liraglutide is a GLP-1 receptor agonist that can help control your appetite and regulate your blood sugar levels. It has been approved for the treatment of both obesity and type 2 diabetes. Liraglutide is typically administered as a daily injection and should be used under medical supervision.
7.2 Exenatide
Exenatide is another GLP-1 receptor agonist that can aid in weight loss efforts. Like liraglutide, it is generally administered as an injection and used in conjunction with a reduced-calorie diet and increased physical activity.
8. Combination medications
Combination medications are weight loss medications that contain multiple active ingredients with different modes of action. These medications offer the potential benefits of multiple weight loss mechanisms.
8.1 Phentermine/topiramate
Phentermine/topiramate is a combination medication that combines an appetite suppressant (phentermine) with an anti-seizure medication (topiramate). This combination can lead to reduced appetite, increased metabolism, and weight loss. Phentermine/topiramate is typically prescribed for individuals with a BMI of 30 or higher or those with a BMI of 27 or higher and at least one weight-related health condition.
8.2 Naltrexone/bupropion
Naltrexone/bupropion is another combination medication that combines an opioid antagonist (naltrexone) with an antidepressant (bupropion). This combination helps control appetite and food cravings while increasing energy expenditure. Naltrexone/bupropion is used in conjunction with a reduced-calorie diet and increased physical activity.
9. Over-the-counter weight loss supplements
Over-the-counter weight loss supplements are widely available without a prescription. These supplements often claim to promote weight loss through various mechanisms, but their effectiveness and safety may vary.
9.1 Green tea extract
Green tea extract is a popular ingredient in many weight loss supplements. It contains catechins, which are believed to help increase fat oxidation and boost metabolism. However, scientific evidence on its effectiveness for weight loss is limited.
9.2 Garcinia cambogia
Garcinia cambogia is a fruit extract that contains hydroxycitric acid. It has been promoted for its potential to suppress appetite and inhibit fat production. However, studies on its effectiveness have shown mixed results, and more research is needed.
9.3 Raspberry ketones
Raspberry ketones are natural compounds found in raspberries that are believed to aid in weight loss by increasing the breakdown of fat. However, there is limited scientific evidence to support their effectiveness, and more research is needed.

In conclusion, there are numerous types of weight loss medications available, each with its own mechanisms of action. It’s important to consult with a healthcare professional to determine which medication may be right for you based on your individual circumstances and health goals. Remember, weight loss medications should always be used in conjunction with a healthy diet and regular exercise for maximum effectiveness.
