Weight loss pills, often referred to as diet pills, appetite suppressants, or weight loss medication, are drugs designed to help with weight loss. They are typically used by individuals with obesity, defined as a body mass index (BMI) of 30 or higher, or a BMI of at least 27 with weight-related health conditions. Prescription weight loss pills are intended to be used in conjunction with a healthy diet and exercise program. While they can be effective in aiding weight loss, they are not a standalone solution and require commitment to lifestyle changes for long-term success. Various types of weight loss pills are available, each with its own unique mechanism of action and potential side effects. Some common prescription weight loss pills include Liraglutide (Saxenda), Semaglutide (Wegovy), Naltrexone-bupropion (Contrave), Phentermine-topiramate (Qsymia), Benzphetamine (Didrex, Regimex), Diethylpropion (Tenuate, Tenuate Dospan), and Orlistat.

Over-the-counter diet pills
There are prescription medications available to treat overweight and obesity. These medications work in different ways, such as by helping people feel less hungry or full sooner, or by making it harder for the body to absorb fat from food. The Food and Drug Administration (FDA) has approved certain prescription appetite suppressants, which can be used for long-term or short-term periods.
Some of the prescription medications approved by the FDA include:
- Orlistat (Xenical, Alli)
- Phentermine-topiramate (Qsymia)
- Naltrexone-bupropion (Contrave)
- Liraglutide (Saxenda)
- Semaglutide (Wegovy)
- Tirzepatide (Zepbound)
These prescription medications are meant to be used alongside a healthy eating plan and regular physical activity. They are typically recommended for people with a body mass index (BMI) of 27 or higher, who also have weight-related health problems such as high blood pressure or type 2 diabetes.
Over-the-counter (OTC) diet pills are also available as weight loss supplements. One example is Alli, which contains Orlistat 60mg as its active ingredient. Alli works in the digestive tract with minimal absorption into the bloodstream, meaning it has little to no effect on the cardiovascular and central nervous systems. It binds to enzymes that break down fats, resulting in about 25% of consumed fat not being absorbed and passing through the digestive system. This reduces the number of calories that enter the body. However, it is important to note that OTC appetite suppressants may interact with medications or cause health problems, so it is recommended to check with a healthcare provider before use.

Prescription weight-loss medications are typically recommended for individuals with a body mass index (BMI) of 27 or higher, especially if they have weight-related health issues such as type 2 diabetes, high blood pressure, or high cholesterol. It is important to note that these medications are not suitable for everyone with a high BMI, and healthcare providers will assess each case individually. Weight loss drugs should be used as part of a holistic approach that includes a nutritious diet and regular exercise.

- Diethylpropion (Tenuate, Tenuate Dospan)
- Phendimetrazine (Prelu-2)
- Phentermine (Adipex-P, Pro-Fast, Lomaira)
These medications have been shown to help people achieve weight loss of 5% or more of their starting body weight, with some participants in studies losing 10% or more. However, it is important to be aware of potential side effects, which may include abnormal sensations, dizziness, altered taste, insomnia, constipation, and dry mouth. Additionally, weight loss drugs may interact with other medications, so it is crucial to consult a healthcare provider before starting any new medication.
The best weight-loss medication is one that helps achieve the desired results with minimal side effects and at an affordable cost. It is important to work with a healthcare professional to find the treatment plan that aligns with an individual's health goals, preferences, and medical history.

Dietary supplements
There are prescription medications available to treat overweight and obesity. These medications work in different ways, such as by helping you feel less hungry or full sooner, or by making it harder for your body to absorb fat from the food you eat. They are meant to be used as part of a weight-control program that includes a healthy eating plan and regular physical activity.
Prescription appetite suppressants are one such type of medication. They work by blocking or increasing specific hormones, neurotransmitters, and/or peptides, thereby making you feel less hungry or full faster when you eat. They are typically recommended for people with a body mass index (BMI) of 30 or higher, or a BMI greater than 27 with weight-related health problems such as type 2 diabetes or high blood pressure.
The Food and Drug Administration (FDA) has approved several prescription appetite suppressants for long-term use, including injectable medications like liraglutide (Saxenda®) and semaglutide (Wegovy®), and pills like naltrexone-bupropion (Contrave®) and phentermine-topiramate (Qsymia®). Other appetite suppressants are approved for short-term use, typically up to 12 weeks.
While prescription medications can be effective in managing weight, they may also have side effects. Experts caution that in some cases, the side effects may outweigh the benefits. Therefore, it is important to consult a healthcare provider before taking any medication or supplement for weight loss.
Some popular dietary supplements that have been associated with weight loss include:
- Vitamin B12: Studies have linked low vitamin B12 levels to obesity, diabetes, and high cholesterol in animals. It is believed to play a role in fat metabolism. However, taking large doses of vitamins can have toxic effects, and symptoms may include appetite loss, nausea, vomiting, weakness, and irregular heartbeat, among others.
- Chromium: This micronutrient has been studied for its potential weight loss benefits, but the research is mixed. Some studies have linked chromium to weight loss, but the benefits tend to be small or negligible. Side effects may include stomach pain and bloating, and there have been reports of kidney damage, liver damage, muscular problems, and skin reactions following large doses.
- Green tea extract: The effectiveness of green tea extract as a weight-loss supplement is disputed.
- Magnesium: The effectiveness of magnesium as a weight-loss supplement is disputed.
- Chitosan: Derived from the exoskeleton of shellfish, chitosan is promoted as a "fat blocker" that prevents the body from absorbing dietary fats. A well-designed study showed that participants taking the supplement lost on average about six pounds.

Side effects and risks
Prescription diet pills, also known as appetite suppressants, are medications that can help with weight loss for people with obesity. They work by blocking or increasing specific hormones, neurotransmitters, and/or peptides, resulting in a reduced appetite or an increased feeling of fullness. While these pills can aid in weight loss, it's important to be aware of their potential side effects and risks.
Firstly, it's crucial to understand that prescription diet pills are generally recommended only for individuals with a body mass index (BMI) of 27 or higher, indicating obesity. Healthcare providers may also suggest these pills for individuals with a BMI greater than 27 who have weight-related health issues such as type 2 diabetes, high blood pressure, high cholesterol, or joint pain. Taking these pills without meeting these criteria can be unsafe and may cause more harm than good.
Secondly, prescription diet pills are associated with a range of side effects, which differ depending on the specific medication. Some common side effects include digestive issues, allergic reactions, pancreatitis, gallbladder problems, and kidney damage. In rare cases, severe liver injury has been reported with certain medications. Additionally, some pills may interfere with oral birth control, and certain combinations of medications may increase the risk of uncontrolled bleeding. It's imperative to consult a healthcare professional before taking any prescription diet pills to understand the specific side effects and risks associated with the medication.
Moreover, short-term prescription appetite suppressants come with a higher risk of severe side effects and addiction. Some of these suppressants can interact with other medications, including antidepressants and anti-anxiety drugs, leading to adverse reactions. They can also exacerbate certain health conditions, such as high blood pressure, mood disorders, and glaucoma. Over-the-counter (OTC) appetite suppressants or weight-loss supplements may contain stimulants like ephedra, ephedrine, or caffeine, and have been linked to serious health issues, including heart attacks, seizures, strokes, and even death.
Lastly, it's important to recognize that prescription diet pills are not a standalone solution for weight loss. They should be used in conjunction with a healthy eating plan and regular physical activity. Lifestyle changes are crucial for long-term weight management, and medications should be viewed as a supplementary tool under the guidance of a healthcare professional.
