Weight loss medications are designed for short-term or long-term use and work best in conjunction with a healthy diet and exercise. Prescription appetite suppressants, for example, can help with weight loss by reducing appetite or creating a sense of fullness. Phentermine and topiramate extended-release capsules are a combination of two drugs that work together to suppress appetite and aid in weight loss. Liraglutide (Saxenda), Semaglutide (Wegovy), Naltrexone-bupropion (Contrave), and Phentermine-topiramate (Qsymia) are some FDA-approved prescription appetite suppressants. However, it is crucial to consult a healthcare provider before taking any weight loss medication to ensure safety and suitability.

What You'll Learn
Appetite suppressants
- Liraglutide (Saxenda®)
- Semaglutide (Wegovy®)
- Naltrexone-bupropion (Contrave®)
- Phentermine-topiramate (Qsymia®)
The FDA has approved the following prescription appetite suppressants for short-term use only, typically up to 12 weeks:
- Benzphetamine (Didrex®, Regimex®)
- Diethylpropion (Tenuate®, Tenuate Dospan®)
- Phendimetrazine (Prelu-2®)
- Phentermine (Dipex-P®, Atti-Plex P®, Pro-Fast® and others)
These short-term appetite suppressants are controlled substances, which means they have addiction potential and can be dangerous if not used as intended. It is important to consult a healthcare provider before starting any appetite suppressant to ensure they are safe and suitable for you.
Some over-the-counter (OTC) appetite suppressants are available, but none have been approved by the FDA. These include supplements such as bitter orange, garcinia cambogia, glucomannan, and green tea extracts. While these supplements claim to reduce appetite, there is limited evidence of their effectiveness and safety.

Prescription vs. over-the-counter
Prescription appetite suppressants are regulated medications that require a doctor's prescription to obtain. They are typically recommended for individuals with a body mass index (BMI) of 30 or higher, or a BMI greater than 27 with obesity-related health issues such as type 2 diabetes, high blood pressure, high cholesterol, or joint pain. These medications work by reducing appetite or increasing feelings of fullness, helping individuals achieve an average weight loss of 5% or more of their starting body weight. Examples of prescription appetite suppressants include Liraglutide (Saxenda), Semaglutide (Wegovy), Naltrexone-bupropion (Contrave), and Phentermine-topiramate (Qsymia). It is important to consult a healthcare provider before taking prescription appetite suppressants as they may interact with other medications and have side effects.
On the other hand, over-the-counter (OTC) weight loss pills can be purchased without a prescription. The only FDA-approved OTC weight loss medication is Alli (orlistat), which is also available as a prescription-strength option. Other OTC products are considered supplements and are not regulated by the FDA, so their safety and effectiveness may not be adequately studied. While OTC appetite suppressants may be more convenient to access, they can also carry risks. Some may contain stimulants like ephedra, ephedrine, or caffeine, and have been linked to serious side effects, including heart attack, seizure, stroke, and death. As with prescription appetite suppressants, consulting a healthcare provider before taking OTC weight loss pills is essential to ensure safety and avoid potential interactions with medications or health conditions.
Prescription weight loss medications are typically recommended for individuals who have not achieved their desired weight loss through diet and exercise alone. Healthcare professionals can consider a patient's lifestyle, BMI, and health conditions when prescribing these medications and can monitor their progress and side effects. This allows for dosage adjustments or alternative medications if needed. Additionally, prescription weight loss pills are often combined with lifestyle changes, such as a nutritious diet and regular exercise, to maximize their effectiveness.
OTC weight loss pills, on the other hand, may be preferred by individuals who want a more convenient option or are not suitable candidates for prescription medications. While Alli (orlistat) is the only FDA-approved OTC weight loss medication, other supplements may still offer benefits. For example, Plenity is a medical device containing cellulose and citric acid that has been FDA-cleared as a weight-loss aid in the form of a prescription-only pill. However, the lack of regulation and studies on OTC supplements may raise concerns about their safety and effectiveness compared to prescription options.

Side effects
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 your body and brain experience appetite and hunger, making you feel less hungry or full faster after eating less food.
Each type of appetite suppressant works differently, so they all have different side effects. Some common side effects of diet pills include:
- Gastrointestinal problems: Nausea, vomiting, acid reflux, bloating, stomach cramps, diarrhea, and/or constipation. These symptoms are generally mild and temporary but can be difficult to manage.
- Rapid or irregular heartbeat (tachycardia or arrhythmia).
- Mood changes, such as depression or anxiety.
- Cognitive (mental) changes like agitation, delirium, or psychosis.
- Headache, fatigue, dizziness, and indigestion.
- Allergic reactions, injection site reactions, sleepiness, hair loss, and burping.
- Insomnia, restlessness, drug dependence, abuse potential, and withdrawal symptoms.
- Oily spotting, soft stools, and dry mouth.
- Kidney stones, increased body temperature, and decreased sweating.
It is important to consult with a healthcare provider before taking any diet pills, as they can interact with medications or cause health problems. Additionally, some diet pills are only recommended for short-term use due to the risk of dependence and other side effects.

Weight loss drugs
There are several weight loss drugs available, and the specific medication prescribed may depend on individual needs and health factors. One of the most widely used weight loss medications is phentermine, which has been in use for a long time. Phentermine is available in capsule or tablet form, with different dosage strengths. It can also be combined with topiramate to further reduce appetite and cravings. Other prescription weight loss drugs include liraglutide (Saxenda), an injectable medication, and naltrexone-bupropion (Contrave), which comes in pill form.
The Food and Drug Administration (FDA) in the United States has approved several prescription weight loss medications for long-term use. These include orlistat (Xenical, Alli), phentermine-topiramate (Qsymia), naltrexone-bupropion (Contrave), liraglutide (Saxenda), semaglutide (Wegovy), and tirzepatide (Zepbound). Some of these drugs are approved for use in adults and children aged 12 and older. It is worth noting that not all insurance plans cover medications for weight loss, so individuals may need to check with their insurance provider.
While prescription weight loss drugs can be effective, they may also have side effects. For example, phentermine may cause headaches, overstimulation, high blood pressure, insomnia, rapid or irregular heart rate, and tremors. Other potential side effects of weight loss medications include abnormal sensations, dizziness, altered taste, insomnia, constipation, and dry mouth. It is important to be aware of these side effects and discuss them with a healthcare provider before starting any medication.
In addition to prescription medications, there are also over-the-counter (OTC) diet pills and appetite suppressants available. However, these should also be used with caution and under the guidance of a healthcare provider, as they may interact with other medications or cause health problems. Overall, weight loss drugs can be a useful tool in managing weight, but they should be used as part of a comprehensive treatment plan that includes lifestyle changes, physical activity, and, in some cases, behavioural therapy.

Healthy eating plans
Appetite suppressants are a type of diet pill that can aid weight loss by reducing appetite or increasing feelings of fullness. They are available both over the counter (OTC) and by prescription. Before taking any OTC diet pills, it is important to consult a healthcare professional to ensure they do not interact with any medications or cause health issues.
Several prescription appetite suppressants have been approved by the Food and Drug Administration (FDA) for long-term use. These include Liraglutide (Saxenda), which is administered via subcutaneous injection, and Naltrexone-bupropion (Contrave), which is a pill. Other prescription appetite suppressants are approved for short-term use, typically up to 12 weeks, and are considered controlled substances. These include Benzphetamine (Didrex, Regimex) and Phentermine (Dipex-P, Atti-Plex P, Pro-Fast, among others).
When considering prescription appetite suppressants, it is crucial to consult a healthcare provider to ensure their safety and suitability for your individual needs. This involves an in-depth conversation about your health and weight management goals to determine the best course of action.
While diet pills can be a tool in weight loss, it is important to remember that they should be used in conjunction with a healthy eating plan and, if needed, increased physical activity. A healthy eating plan should focus on nutrient-dense foods that provide the body with the fuel it needs to function optimally. This includes a variety of fruits and vegetables, whole grains, lean proteins, healthy fats, and adequate hydration.
Additionally, creating a calorie deficit, where you burn more calories than you consume, is key to weight loss. This can be achieved through portion control, reducing added sugars and unhealthy fats, and making conscious food choices. It is important to note that a healthy eating plan should not be overly restrictive but rather a sustainable and enjoyable approach to nutrition that promotes overall health and weight management.
