Prescribed diet pills, also known as weight-loss medication, are drugs that can be taken orally or administered through subcutaneous injections. They are typically prescribed to patients with a body mass index (BMI) of 30 or higher, or a BMI of 27 with weight-related health conditions such as diabetes or high blood pressure. These medications work by suppressing appetite, reducing the absorption of fats, or impacting hormones and enzymes that regulate weight. While they can be effective in aiding weight loss, they are not without risks and side effects, and should be used in conjunction with a healthy diet and regular exercise.

What You'll Learn
Who should take them
Prescription weight loss medications are intended for people who are obese or overweight with a body mass index (BMI) of 30 or greater, or a BMI of 27 or more if they have weight-related health conditions. Obesity is a chronic disease that affects over 4 in 10 adults in the United States, and nearly 1 in 10 Americans have severe obesity.
Weight loss medications are designed to help people who have health problems related to being overweight or obese. Healthcare professionals use BMI to help decide whether a patient might benefit from weight management medication. Prescription medications to treat overweight and obesity work in different ways, such as helping patients feel less hungry or full sooner, or making it harder for the body to absorb fat from food.
Appetite suppressants are a type of weight-loss medication (sometimes called diet pills) for people with a BMI over 30. They affect how the body and brain experience appetite and hunger, making patients feel less hungry or full faster after eating less food. As a result, patients may take in fewer calories and lose weight. Appetite suppressants are generally safe if taken as prescribed, but short-term prescriptions require more caution due to possible severe side effects and addiction potential. They can also interfere with hormonal birth control and other medications, including antidepressants and anti-anxiety drugs.
Weight loss medications are not recommended for pregnant or breastfeeding women, people with glaucoma, hyperthyroidism, a history of drug abuse, or seizure disorders, or those taking opioids for chronic pain. Patients should inform their doctor about any allergies or sensitivities, other medications they are taking, and their medical history before taking weight loss medication.

Side effects
Some common side effects of prescription diet pills include gastrointestinal problems such as nausea, diarrhea, vomiting, constipation, abdominal pain, and indigestion. Other possible side effects include headache, fatigue, dizziness, bloating, gas, insomnia, dry mouth, and decreased appetite. In rare cases, more serious side effects such as allergic reactions, pancreatitis, gallbladder problems, kidney damage, and severe liver injury have been reported.
Some prescription diet pills, such as Wegovy and Ozempic, have been associated with a diabetes eye complication called retinopathy, which can result in vision loss or blindness. These drugs can also interfere with hormonal birth control, so it is important to consult a healthcare professional before taking any medication.
It is important to note that prescription diet pills are typically intended for short-term use, and long-term use may come with additional risks and side effects. Additionally, some prescription diet pills have the potential for addiction, especially if used outside of their intended, prescribed use. If you have a substance use disorder (SUD) or a family history of SUD, be sure to discuss this with your healthcare provider before starting any medication.
While prescription diet pills can be effective in managing weight and improving health, it is crucial to carefully consider the potential side effects and risks before taking any medication. It is always advisable to consult a healthcare professional to determine the most appropriate treatment plan for your individual needs.

Effectiveness
The effectiveness of prescribed diet pills is contingent on several factors, including individual health, lifestyle, and the type of medication. While some people may experience significant weight loss, others may lose little to none. It is important to note that prescribed diet pills are not a substitute for lifestyle changes and are intended to be used in conjunction with a healthy diet and regular exercise.
Prescribed diet pills can be effective in curbing appetite and reducing the body's ability to absorb fats from food. For example, Orlistat, a commonly prescribed weight-loss medication, blocks the enzyme that breaks down fats in food, thereby inhibiting the absorption of dietary fats. While some patients may lose about 5% of their body weight with Orlistat, it is designed to be used with a reduced-calorie diet to prevent weight regain.
Other prescribed medications, such as Qsymia, combine phentermine, which suppresses appetite, with topiramate, which causes weight loss by helping individuals feel full, making foods less appealing, and burning more calories. Bupropion (Wellbutrin), an aminoketone, is another example of a prescribed medication that is used to assist in weight loss and treat depression.
The effectiveness of prescribed diet pills is also influenced by individual health considerations. Diet pills are typically prescribed to individuals with a body mass index (BMI) of 30 or higher, or a BMI of 27 with weight-related health conditions such as diabetes, high blood pressure, joint problems, or sleep apnea. Additionally, certain medications may be contraindicated for individuals with specific health conditions, such as uncontrolled blood pressure or vision changes, or for women who are pregnant or planning to become pregnant.
Furthermore, the effectiveness of prescribed diet pills is contingent on proper patient education and monitoring by healthcare providers. Patients should be informed about potential side effects, expected outcomes, and the importance of adhering to prescribed medication regimens and lifestyle changes. Healthcare providers play a crucial role in selecting the most appropriate medication for each patient, adjusting dosages, and providing ongoing support and monitoring to ensure the safe and effective use of prescribed diet pills.
While prescribed diet pills can be effective in promoting weight loss, they are not a "magic bullet" and should be used under medical supervision as part of a comprehensive weight-loss program.

Cost
The cost of prescription diet pills is an important factor to consider when deciding whether to take them. The price of these medications can vary depending on the specific drug, dosage, and duration of treatment. It's important to note that some insurance plans may cover the cost of certain medications, especially if they are prescribed for specific conditions such as Type 2 diabetes.
For example, the prescription weight loss drug Xenical costs around $800 for a 1-month supply. There are also generic versions of the active ingredient orlistat available at a lower cost. The over-the-counter version, Alli, costs less than $60 for a month's supply. It is important to note that these prices may vary depending on the location and the specific pharmacy.
Another popular prescription weight loss medication is Wegovy, which was approved by the FDA in 2021. Wegovy is a brand name for semaglutide and is administered as an injection. While it may be covered by insurance for people with Type 2 diabetes, the cost can be a long-term issue for those who have to pay out of pocket.
The cost of prescription diet pills can be a significant factor in deciding whether to take them. It is important to discuss the medication's cost and potential side effects with a healthcare provider before starting any treatment. Additionally, it is worth noting that some weight loss medications are intended to be used in combination with a reduced-calorie eating plan and regular exercise, which may also incur additional costs.

Safety
The safety of prescription diet pills is a complex issue that requires careful consideration. Firstly, it is important to understand that these medications are intended for individuals with obesity, typically defined as a body mass index (BMI) of 30 or higher. For those with a BMI of at least 27, prescription weight loss drugs may be an option if accompanied by weight-related health conditions such as diabetes or high blood pressure.
Prescription diet pills work by suppressing appetite or making individuals feel full faster. While these medications can aid in weight loss, they are not a standalone solution. They are intended to be used in conjunction with a reduced-calorie eating plan and regular physical activity for optimal effectiveness and safety. Combining these pills with other weight loss products can be dangerous and should only be done under medical supervision.
The safety of prescription diet pills also depends on proper usage and individual health considerations. Long-term prescription appetite suppressants are generally safe if taken as prescribed. However, short-term prescription appetite suppressants require more caution due to potential severe side effects, addiction, and interaction with other medications. It is crucial to disclose all medications, over-the-counter products, and herbal supplements to your healthcare provider to avoid harmful interactions.
Pregnant or breastfeeding individuals should refrain from taking weight-loss medications, as they may harm the fetus or the infant. Additionally, some diet pills can interfere with hormonal birth control, so it is important to discuss these potential interactions with a healthcare provider. Individuals with certain pre-existing health conditions, such as high blood pressure, mood disorders, glaucoma, seizure disorders, or those taking opioids for chronic pain, should approach these medications with caution and seek medical advice.
It is worth noting that some prescription weight loss drugs can be extremely expensive, and insurance coverage may be limited. Furthermore, side effects associated with these medications should be carefully considered. While generally mild and temporary, side effects may include nausea, constipation, headache, vomiting, dizziness, insomnia, dry mouth, and diarrhea. Rare cases of severe liver injury have been reported with certain medications, although the causation is not yet certain.
