However, there is no single pill that is widely considered the safest and most effective overall. The best weight-loss pill for an individual will be the one that helps them achieve their desired results with minimal side effects and at an affordable cost. Some of the most popular weight-loss pills include Qsymia, Wegovy, Ozempic, Contrave, Orlistat, and Phentermine. These pills typically work by reducing appetite and cravings, making individuals feel full faster, or reducing fat absorption in the body. While these pills can be effective, they are most beneficial when combined with a healthy diet and regular exercise.

Prescription appetite suppressants
It is important to note that prescription appetite suppressants are not a standalone solution for weight loss. Studies have shown that they are most effective when combined with a reduced-calorie eating plan and regular physical activity. Additionally, they are not suitable for everyone, and healthcare providers typically recommend them for individuals with a BMI of 30 or higher or a BMI greater than 27 with weight-related health issues such as type 2 diabetes, high blood pressure, or high cholesterol.
There are several prescription appetite suppressants available, including Phentermine-topiramate (Qsymia), Benzphetamine (Didrex®, Regimex®), Diethylpropion (Tenuate®, Tenuate Dospan®), Phendimetrazine (Prelu-2®), and Phentermine (Adipex-P®, Dipex-P®, Atti-Plex P®, Pro-Fast®, Lomaira, and others). These medications are typically considered controlled substances due to their addiction potential and should be used with caution.
Other FDA-approved prescription appetite suppressants approved for long-term use include Liraglutide (Saxenda®), Semaglutide (Wegovy®), Naltrexone-bupropion (Contrave®), and Tirzepatide (Zepbound®). These medications are administered as injections and work by reducing appetite and increasing feelings of fullness.
While prescription appetite suppressants can be beneficial for weight loss, they should be used under the guidance of a healthcare provider. It is important to discuss potential side effects, which can vary depending on the specific medication. Additionally, individuals with a history of substance use disorder (SUD) or a family history of SUD should disclose this information to their healthcare provider before starting any appetite suppressant medication.

FDA-approved prescription appetite suppressants
There is no one weight-loss pill that is widely considered to be the safest and most effective overall. However, there are a number of FDA-approved prescription appetite suppressants on the market. These medications work by blocking or increasing specific hormones, neurotransmitters and/or peptides, which affect how your body and brain experience appetite and hunger.
Prescription appetite suppressants are recommended for people with obesity, which is typically defined as having a body mass index (BMI) of 30 or higher. They can also be prescribed for people with a BMI greater than 27 who have weight-related health conditions, such as high blood pressure, high cholesterol, or type 2 diabetes.
- Phentermine-topiramate (Qsymia®): This is a pill that combines two medications, phentermine and topiramate, to decrease appetite and cravings. It is available in both generic and brand-name versions for people aged 17 and older. However, it is a controlled substance and comes with health risks.
- Benzphetamine (Didrex®, Regimex®): This is a short-term appetite suppressant that is a controlled substance.
- Diethylpropion (Tenuate®, Tenuate Dospan®): This is another short-term appetite suppressant.
- Phendimetrazine (Prelu-2®): This short-term appetite suppressant is also a controlled substance.
- Orlistat (Xenical, Alli): Orlistat is a prescription weight-loss pill that can also be purchased over the counter at a lower dosage. It helps to reduce fat absorption and can be taken by adults up to three times per day with meals. It is generally safe but can cause side effects such as gastrointestinal symptoms.
- Liraglutide (Saxenda, Victoza): This medication is approved for weight loss in adults and children aged 12 and older. It is also used to treat type 2 diabetes. Liraglutide acts on hormones that signal hunger and fullness, helping to reduce appetite and cravings.
- Semaglutide (Wegovy): This medication was FDA-approved in 2021 for adults and children aged 12 and older with obesity or excess weight and weight-related medical problems. It is administered as an injection and is intended to be used indefinitely, in combination with a healthy diet and exercise.
- Tirzepatide (Mounjaro, Zepbound): Tirzepatide was previously approved to treat type 2 diabetes and is now also approved to treat obesity in adults with a BMI of 30 or greater.
- Contrave (naltrexone HCl/bupropion HCl): Contrave is an oral tablet that combines two medications, naltrexone and bupropion, to reduce appetite and cravings. It is the only FDA-approved 2-in-1 weight-loss pill and is designed for adults with obesity or those who are overweight with at least one weight-related health condition.
It is important to note that prescription appetite suppressants are most effective when combined with lifestyle changes, such as a nutritious diet and regular exercise. They should be used under the guidance of a healthcare professional, who can help determine which medication is suitable for your specific needs and monitor for any potential side effects.

Weight loss pills vs injections
Weight loss pills and injections are two forms of medication used to help people lose weight. Both can be effective, but they have different pros and cons.
Weight Loss Pills
Weight loss pills are generally more affordable than injections and do not require the use of needles. Pills also offer a variety of medications to choose from. However, they may need to be taken daily, and there are often rules for timing the dose in relation to meals. Pills may also be more likely to cause stomach-related side effects, such as nausea, bloating, and abdominal pain.
Some popular weight loss pills include:
- Qsymia: a controlled substance that combines phentermine and topiramate. It is highly effective but may not be suitable for those with a history of substance misuse or dependency.
- Contrave: a pill that combines naltrexone and bupropion. It reduces appetite and food cravings, with over 40% of adults losing at least 5% of their body weight in initial studies.
- Orlistat (Xenical): a prescription pill taken orally three times a day with meals. It helps adults absorb less fat from meals and can reduce the risk of regaining weight.
- Phentermine: available as a 15 mg or 30 mg capsule, or an 18.75 mg or 37.5 mg tablet. Side effects may include headache, overstimulation, high blood pressure, insomnia, and rapid or irregular heart rate.
- Appetite suppressants: these can be prescription or over-the-counter and work by lessening your appetite or making you feel full faster.
Weight Loss Injections
Weight loss injections tend to be more effective than pills, with fewer restrictions around the timing of the dose. They are typically only administered once a week, which may be easier to stick to. However, injections obviously require the use of needles, which can be a source of anxiety or discomfort for some people. Injections also tend to be significantly more expensive than weight loss pills.
Some popular weight loss injections include:
- Semaglutide (Wegovy, Ozempic, Rybelsus): a GLP-1 receptor agonist that slows the rate at which the stomach empties, making you feel fuller for longer. It can also reduce hunger signals in the brain. It is available in both injectable and oral tablet forms.
- Tirzepatide (Mounjaro): a medication previously approved to treat type 2 diabetes.
- Liraglutide (Victoza): a daily injectable medication that acts on hormones, making you feel full quicker and reducing hunger signals. Side effects may include nausea, diarrhoea, constipation, vomiting, headache, decreased appetite, and fatigue.
Both weight loss pills and injections can be effective tools as part of an overall weight loss strategy, but the best option for an individual will depend on their specific needs, preferences, and medical history. It is important to consult with a healthcare professional before starting any new medication or weight loss plan.

Combining weight loss pills with lifestyle changes
While weight loss pills can be effective, they work best when combined with lifestyle changes. A healthy diet and regular exercise are the most commonly recommended lifestyle changes to be implemented alongside weight loss medication.
A healthy diet typically involves reducing your calorie intake and eating more nutritious foods. This might mean cutting down on processed foods, sugary drinks, and unhealthy fats, and increasing your consumption of fruits, vegetables, lean proteins, and whole grains. Some weight loss pills, such as Orlistat, are designed to be taken alongside a low-fat, low-calorie diet. It's important to note that medications do not replace healthy eating habits as a means of losing weight; they are intended to complement and enhance your efforts.
Regular exercise is another crucial component of a healthy lifestyle. This can include activities such as walking, jogging, swimming, cycling, or strength training. Exercise helps burn calories, increase metabolism, and build muscle, all of which contribute to weight loss and a healthier body composition. Combining weight loss pills with regular exercise can further boost the effectiveness of the medication and lead to more significant results.
In addition to diet and exercise, other lifestyle changes can also impact your weight loss journey. Getting adequate sleep, managing stress, and addressing any eating triggers are important factors. Sleep plays a vital role in regulating hormones that control hunger and appetite. Stress and certain triggers can also influence eating habits and emotional eating, so finding healthy coping mechanisms is essential.
Finally, it's important to consult with a healthcare professional before starting any weight loss medication. They can help you understand the potential risks and benefits of different pills and determine which one is best suited to your needs and lifestyle. Combining weight loss pills with healthy lifestyle changes can improve your chances of achieving and maintaining your weight loss goals.
