There are many different types of diet pills, also known as weight-loss or appetite-suppressant medication. These pills are designed to help people with obesity or a high BMI lose weight by reducing their appetite or making them feel full faster. Prescription appetite suppressants can be administered orally or via injection, and they can be used for either short-term or long-term weight loss. Some examples of FDA-approved prescription appetite suppressants include Liraglutide (Saxenda), Semaglutide (Wegovy), Naltrexone-bupropion (Contrave), and Phentermine-topiramate (Qsymia). Over-the-counter (OTC) diet pills are also available, but it is important to consult a healthcare provider before using them as they may interact with medications or cause health problems.

What You'll Learn
Prescription vs. over-the-counter diet pills
There are two types of diet pills: prescription weight-loss pills and over-the-counter (OTC) weight-loss pills. Prescription weight-loss pills are medications that require a doctor's prescription. They are typically recommended for individuals with obesity, defined by a body mass index (BMI) of 30 or higher. Prescription appetite suppressants work by blocking or increasing specific hormones, neurotransmitters, and/or peptides, leading to reduced hunger or an earlier sense of fullness. These pills are generally considered safe for long-term use if taken as directed, but they may have side effects and interact with other medications.
Over-the-counter weight-loss pills, on the other hand, can be purchased without a prescription and are commonly found in vitamin shops and drugstores. The only FDA-approved OTC weight-loss medicine is Alli (orlistat). Other OTC products are classified as supplements, which are not regulated by the FDA and lack rigorous studies to confirm their safety and effectiveness. These OTC supplements may contain ingredients not listed on their labels, such as sibutramine and phenolphthalein, which have been connected to adverse effects like increased blood pressure and heart rate. Therefore, it is crucial to consult a healthcare provider before taking OTC diet pills to ensure they are safe and do not interfere with any current medications.
Prescription weight-loss pills are generally recommended for individuals with obesity or a high BMI who have struggled to lose weight through diet and exercise alone. Healthcare providers can personalise treatment plans and monitor progress and side effects. They can also adjust dosages or recommend alternative medications if needed. Prescription pills can be administered orally or through injections, with the latter being equally effective according to data from Novo Nordisk and Pfizer. Examples of FDA-approved prescription appetite suppressants include liraglutide (Saxenda), semaglutide (Wegovy), naltrexone-bupropion (Contrave), and phentermine-topiramate (Qsymia).
In contrast, over-the-counter weight-loss pills may be more accessible for individuals who do not require intensive medical intervention or who prefer a more convenient option. However, it is important to note that OTC pills may not offer the same level of personalised guidance and monitoring as prescription pills. While some OTC options are available, such as Alli (orlistat), the lack of regulation and potential presence of unlisted ingredients emphasise the importance of consulting a healthcare provider before use.
In summary, prescription weight-loss pills are recommended under medical supervision for individuals with obesity or related health conditions. They offer a personalised approach with monitoring and adjustments by healthcare providers. On the other hand, over-the-counter weight-loss pills provide convenience and accessibility but may lack rigorous safety studies and regulation. As such, consulting a healthcare provider before taking any diet pills is essential to ensure safety, effectiveness, and compatibility with existing medications.

Appetite suppressants
There are prescription and over-the-counter (OTC) appetite suppressants. Prescription appetite suppressants can be for long-term or short-term use. The Food and Drug Administration (FDA) has approved several prescription appetite suppressants for long-term use, including Liraglutide (Saxenda®), an under-the-skin injection medication, and Semaglutide (Wegovy®), also an injection medication. Naltrexone-bupropion (Contrave®) and Phentermine-topiramate (Qsymia®) are examples of prescription appetite suppressant pills. Other FDA-approved prescription appetite suppressants are for short-term use only, typically up to 12 weeks (three months). These include Benzphetamine (Didrex®, Regimex®) and Diethylpropion (Tenuate®, Tenuate Dospan®).
It is important to consult your healthcare provider before using OTC diet pills, as they may interact with medications or cause health problems. While appetite suppressants can aid in weight loss, they are not without risks and side effects. Each person's experience with appetite suppressants may vary, and it is crucial to work with a healthcare professional to determine if they are a suitable option for you.
Some natural appetite suppressants are also available as supplements, such as those containing green tea extract, glucomannan, or garcinia cambogia. These supplements often contain a combination of ingredients that are claimed to help with weight loss by curbing appetite, boosting metabolism, or blocking the absorption of fat or carbohydrates. However, it is important to note that the effectiveness and safety of these supplements may not be as rigorously studied as prescription appetite suppressants.

FDA-approved prescription medications
There are several FDA-approved prescription medications for weight loss. These medications are typically recommended for individuals with a body mass index (BMI) of 27 or higher who also have weight-related health issues such as high blood pressure, type 2 diabetes, or high cholesterol. Here are some of the FDA-approved prescription medications:
Orlistat (Xenical, Alli)
Orlistat is a lipase inhibitor that comes in capsule form. It works by blocking the absorption of fat in the gut, reducing the amount of fat absorbed after eating. It is often recommended for individuals who consume fatty foods. The typical dosage is 120 milligrams, taken three times daily, and it should be combined with a reduced-calorie diet.
Liraglutide (Saxenda, Victoza)
Liraglutide is a daily injectable medication that acts on hormones, making individuals feel full quicker and reducing hunger signals. It is approved for weight loss and the treatment of type 2 diabetes. The dosage ranges from 0.6 mg to 3 mg per day, and it can be injected once daily. Liraglutide may cause side effects such as nausea, diarrhoea, constipation, vomiting, headache, and fatigue.
Naltrexone-bupropion (Contrave)
Naltrexone-bupropion is a combination medication that includes an opioid receptor antagonist (naltrexone) and an antidepressant (bupropion). It works by decreasing cravings and appetite by affecting the pleasure-reward areas of the brain. It is typically started at a low dose and gradually increased to four tablets per day. Common side effects include nausea, constipation, headache, vomiting, dizziness, insomnia, dry mouth, and diarrhoea. Individuals with seizure disorders or those taking opioids for chronic pain should not take this medication.
Semaglutide (Wegovy)
Semaglutide is a brand name for a GLP-1 receptor agonist, approved by the FDA in 2021. It is administered as an injection and is approved for adults and children aged 12 and above with obesity or a high BMI and weight-related medical issues. The dosage is gradually increased over several weeks to reach the target dosage of 2.4 mg. It is intended for long-term use, combined with a healthy diet and exercise. Side effects may include gastrointestinal symptoms, headache, dizziness, and fatigue.
Tirzepatide (Zepbound)
Zepbound is an injectable medication approved for adults with obesity. It has shown statistically significant weight loss in individuals who also dieted, exercised, and took the medication. The recommended dosage is 5-15 mg, injected once weekly. Common side effects may include an increased risk of medullary thyroid carcinoma, and it may interact with Synthroid. Individuals with a personal or family history of medullary thyroid carcinoma or multiple endocrine neoplasia syndrome type 2 should not take this medication.
It is important to note that these medications should be used under medical supervision and in conjunction with a healthy diet and exercise regimen. Additionally, some medications may have specific restrictions or side effects, so it is essential to consult a healthcare provider before starting any weight loss medication.

Weight-loss injections vs. pills
There are two main types of diet pills: prescription and over-the-counter (OTC). Prescription appetite suppressants can be used for long- or short-term weight loss. They work by reducing your appetite or making you feel full faster. The Food and Drug Administration (FDA) has approved several prescription appetite suppressants for long-term use, including Liraglutide (Saxenda), Semaglutide (Wegovy), and Naltrexone-bupropion (Contrave). Other FDA-approved prescription appetite suppressants, such as Benzphetamine (Didrex, Regimex) and Diethylpropion (Tenuate, Tenuate Dospan), are intended for short-term use only.
Now, let's compare weight-loss injections and pills. Both methods have their advantages and disadvantages, and the best option depends on individual preferences and health considerations. Here are some key points to consider:
Effectiveness:
According to scientific research, injections are generally more effective for weight loss than pills. Studies have shown that people who used Mounjaro injections lost around 22.5% of their body weight after 88 weeks, while those who used Wegovy injections lost approximately 15% after 68 weeks. In comparison, orlistat pills resulted in weight loss of at least 10% in one in five people after a year.
Convenience:
Pills are typically more convenient as they are easier to administer than injections. However, injector pens are designed to be user-friendly, and the pain associated with injections is usually mild or non-existent.
Frequency:
Most weight-loss injections are administered weekly, except for Saxenda, which is taken daily. Pills may also need to be taken daily, depending on the medication.
Side Effects:
Injections tend to cause gastrointestinal side effects, such as nausea, vomiting, diarrhoea, and constipation. Pills, such as orlistat, can also cause side effects, including headache, abdominal pain, and frequent oily stools. It is important to note that side effects may vary for different individuals and medications.
Cost:
Pills, such as Orlistat, are generally more affordable than injectable weight-loss solutions.
Individual Variability:
It is essential to recognize that everyone's experience with weight-loss treatments may vary. While research provides valuable insights, the best approach is to consult with a healthcare provider to determine the most suitable option for your specific needs and health profile.
In summary, while injections have shown greater effectiveness in weight loss studies, pills offer the convenience of oral administration and are generally more affordable. The choice between injections and pills ultimately depends on individual preferences, health considerations, and medical advice.

Side effects and risks
Diet pills, also known as appetite suppressants, are a type of weight-loss medication for people with obesity (a body mass index, or BMI, over 30). They affect how the body and brain experience appetite and hunger, making users feel less hungry or full faster after eating less food. Diet pills can be prescription or over-the-counter (OTC), and prescription appetite suppressants can be for long-term or short-term use.
There are several side effects and risks associated with the use of diet pills. Firstly, they can interact with other medications, including antidepressants, anti-anxiety drugs, and oral birth control pills, leading to potential health complications. Additionally, diet pills may worsen certain pre-existing health conditions such as high blood pressure, mood disorders, and glaucoma. It is crucial to consult a healthcare provider to assess the benefits and risks of taking diet pills while considering individual medical histories.
Some specific diet pills and their associated side effects include:
- Orlistat (Xenical, Alli): Mild and temporary side effects such as nausea, constipation, headache, vomiting, dizziness, insomnia, dry mouth, and diarrhea. It may also interfere with the absorption of vitamins A, D, E, and K, requiring additional supplementation. Rare cases of severe liver injury have been reported, although the causation is uncertain.
- Contrave (Naltrexone-bupropion): Rare but serious side effects may include allergic reactions, seizures, liver damage, increased blood pressure or heart rate, and vision problems. It carries a boxed warning about the increased risk of suicidal thoughts and behaviours.
- Liraglutide (Saxenda): Side effects include nausea, diarrhea, constipation, vomiting, headache, decreased appetite, dyspepsia, fatigue, dizziness, abdominal pain, increased lipase, and renal insufficiency.
- Semaglutide (Wegovy): Side effects include gastrointestinal symptoms, headache, dizziness, and fatigue.
- Phentermine (Qsymia): Classified as a controlled substance due to its potential for addiction and abuse. It is typically combined with other drugs like topiramate, which helps with weight loss by making foods taste less appealing and increasing calorie burn.
It is important to note that the side effects of diet pills can vary depending on the specific medication and the individual's response. Most side effects are mild and tend to improve with continued use, but rare and severe side effects can occur. Pregnant women or those planning to become pregnant should avoid taking weight-loss medications as they may harm the fetus.
