Losing weight can be a daunting task, especially when it feels like every fad diet and trendy workout craze promises unrealistic results. But for individuals who are struggling with obesity or weight-related health issues, prescription weight loss medications can be a game-changer. But what do doctors prescribe for weight loss, and how do these medications work?
Understanding Prescription Weight Loss Medications
Prescription weight loss medications are FDA-approved medications that are designed to help individuals lose weight and maintain weight loss over time. These medications are typically prescribed for individuals who have a body mass index (BMI) of 30 or higher, or for those who have a BMI of 27 or higher and have at least one weight-related health condition, such as high blood pressure, type 2 diabetes, or high cholesterol.
There are several types of prescription weight loss medications available, each with its own unique mechanism of action. Some medications work by suppressing appetite, while others increase feelings of fullness or boost metabolism.
Typical Candidates for Prescription Weight Loss Medications
Doctors typically prescribe weight loss medications for individuals who are struggling with obesity or weight-related health issues. However, not everyone is a good candidate for prescription weight loss medications. Ideal candidates typically include:
- Individuals with a BMI of 30 or higher
- Individuals with a BMI of 27 or higher and at least one weight-related health condition
- Those who have tried other weight loss methods, such as diet and exercise, without seeing significant results
- Those who are willing to make lifestyle changes, such as following a healthy diet and exercise plan, in addition to taking the medication

What is the most commonly prescribed weight loss medication?
The most commonly prescribed weight loss medication is phentermine. Phentermine is a stimulant that suppresses appetite and increases energy. It is typically prescribed for short-term use, usually up to 12 weeks, and is often used in combination with a healthy diet and exercise regimen. Phentermine is available in various forms, including capsules, tablets, and oral disintegrating tablets.
Phentermine works by activating the body’s “fight or flight” response, which increases blood pressure, heart rate, and energy levels. This can help reduce hunger and increase feelings of fullness, leading to weight loss. Phentermine is most effective when combined with a healthy lifestyle, including a balanced diet and regular exercise. It is important to note that phentermine can have side effects, including insomnia, anxiety, and increased heart rate, and should only be taken under the guidance of a healthcare professional.
How do prescription weight loss medications work?
Prescription weight loss medications work in various ways to help individuals lose weight. Some medications, such as orlistat, work by reducing the amount of fat that is absorbed by the body. Others, such as phentermine, work by suppressing appetite and increasing energy. Prescription weight loss medications can also work by increasing the body’s metabolism, reducing hunger, and improving insulin sensitivity.
It is important to note that prescription weight loss medications are not a magic bullet and should be used in combination with a healthy diet and exercise regimen. Prescription weight loss medications can help individuals lose weight, but they should not be relied upon as the sole means of weight loss. It is also important to talk to a healthcare professional before starting any weight loss medication, as they can have side effects and interact with other medications.
Are prescription weight loss medications safe?
Prescription weight loss medications can be safe when used under the guidance of a healthcare professional and in combination with a healthy diet and exercise regimen. However, like all medications, they can have side effects and interact with other medications. It is important to talk to a healthcare professional before starting any weight loss medication, especially if you have any underlying health conditions or take other medications.
Common side effects of prescription weight loss medications include headache, dizziness, and insomnia. More serious side effects can include increased heart rate and blood pressure, and in rare cases, stroke and heart attack. It is important to carefully follow the instructions of your healthcare professional and to report any side effects immediately.
Can I take prescription weight loss medications if I have a medical condition?
It depends on the medical condition. Certain medical conditions, such as high blood pressure, diabetes, and thyroid disorders, may be contraindications for certain weight loss medications. For example, phentermine is not recommended for individuals with high blood pressure, while orlistat may not be suitable for individuals with diabetes.
It is important to talk to a healthcare professional before starting any weight loss medication, especially if you have a medical condition. They can help determine whether a weight loss medication is safe for you and can recommend alternative treatments if necessary. Additionally, a healthcare professional can help monitor your health while taking a weight loss medication and adjust your dosage or treatment plan as needed.
How long can I take prescription weight loss medications?
The length of time you can take prescription weight loss medications varies depending on the medication and your individual needs. Phentermine, for example, is typically prescribed for short-term use, usually up to 12 weeks. Orlistat, on the other hand, can be prescribed for longer periods of time, usually up to 6 months to a year.
It is important to follow the instructions of your healthcare professional and to carefully monitor your progress while taking a weight loss medication. If you do not see significant weight loss within the recommended timeframe, your healthcare professional may recommend alternative treatments or adjust your dosage.
Can I take prescription weight loss medications if I am pregnant or breastfeeding?
In general, it is not recommended to take prescription weight loss medications if you are pregnant or breastfeeding. Many weight loss medications, including phentermine and orlistat, are classified as Category X, which means they should not be used during pregnancy.
Taking weight loss medications during pregnancy can increase the risk of birth defects and other complications. Additionally, weight loss medications can pass into breastmilk and may harm a breastfeeding infant. If you are pregnant or breastfeeding, talk to your healthcare professional about alternative weight loss strategies that are safe for you and your baby.
How much weight can I expect to lose with prescription weight loss medications?
The amount of weight you can expect to lose with prescription weight loss medications varies depending on the medication, your starting weight, and your individual response to the medication. On average, individuals taking prescription weight loss medications can expect to lose 5-10% of their starting weight within the first 6-12 months.
It is important to have realistic expectations when taking a weight loss medication. Prescription weight loss medications are intended to be used in conjunction with a healthy diet and exercise regimen, and can help support weight loss efforts. However, they are not a substitute for healthy lifestyle habits, and may not lead to rapid or extreme weight loss.
