Losing weight can be a daunting task, especially when it feels like you’ve tried every diet and exercise plan under the sun without seeing significant results. While there’s no magic pill that can replace a healthy lifestyle, certain prescription medications can help support your weight loss journey. But what pills can a doctor prescribe for weight loss, and how do they work?
Understanding the Role of Prescription Medications in Weight Loss
Before we dive into the types of prescription medications that can aid in weight loss, it’s essential to understand their role in the process. Prescription weight loss medications are designed to help individuals with a body mass index (BMI) of 30 or higher, or those with a BMI of 27 or higher who have at least one weight-related health condition.
These medications are not a substitute for a healthy diet and regular exercise. Instead, they’re meant to be used in conjunction with a comprehensive weight loss plan to help people reach their goals more efficiently.
The Science Behind Weight Loss Medications
Weight loss medications work in various ways to help reduce body weight. Some medications:
- Suppress appetite, reducing hunger and increasing feelings of fullness.
- Increase metabolism, helping your body burn more calories at rest.
- Reduce fat absorption, limiting the amount of fat your body can absorb from food.
- Affect brain chemistry, influencing hunger hormones and reward centers in the brain.

What are prescription weight loss pills, and how do they work?
Prescription weight loss pills are medications that are approved by the FDA to help with weight loss. They work in different ways, depending on the type of medication. Some suppress appetite, while others increase feelings of fullness or block the absorption of fat. Prescription weight loss pills are typically reserved for people who have a body mass index (BMI) of 30 or higher, or those who have a BMI of 27 or higher and also have a serious weight-related health condition.
When taken as directed, prescription weight loss pills can help people lose weight and improve their overall health. They are often used in combination with a healthy diet and regular exercise to achieve optimal weight loss results. It’s important to note that prescription weight loss pills are not a quick fix and are not meant to be used indefinitely. They are typically prescribed for a short period of time, usually up to a year, to help people get started on their weight loss journey.
What are the most common prescription weight loss pills?
The most common prescription weight loss pills include orlistat (Alli), lorcaserin (Belviq), phentermine (Adipex-P), naltrexone (Contrave), and semaglutide (Wegovy). Each of these medications has its own unique mechanism of action and may be prescribed for different types of weight loss. For example, orlistat works by blocking the absorption of fat, while lorcaserin works by suppressing appetite.
It’s important to talk to a doctor to determine which prescription weight loss pill is right for you. Your doctor will consider your medical history, current health, and weight loss goals when making a recommendation. They will also discuss the potential side effects and risks associated with each medication to ensure it is safe for you to take.

It’s important to talk to your doctor about any concerns you have about the safety of prescription weight loss pills. Your doctor will weigh the potential benefits against the potential risks and help you determine if a prescription weight loss pill is right for you.

How much weight can I expect to lose with prescription weight loss pills?
The amount of weight you can expect to lose with prescription weight loss pills varies depending on the medication and individual factors, such as starting weight and overall health. On average, people who take prescription weight loss pills can expect to lose 5-10% of their starting weight over a 6-12 month period. This translates to a weight loss of 10-20 pounds for someone who weighs 200 pounds.
It’s important to have realistic expectations when it comes to weight loss. Prescription weight loss pills are not a magic bullet, and they will not result in rapid or extreme weight loss. Instead, they are meant to help people achieve a healthy and sustainable rate of weight loss over time. Combining prescription weight loss pills with a healthy diet and regular exercise can help people achieve their weight loss goals.
Do I need to exercise and diet while taking prescription weight loss pills?

The length of time that prescription weight loss pills need to be taken varies depending on the medication and individual factors, such as weight loss goals and overall health. In general, prescription weight loss pills are prescribed for a short period of time, usually up to a year. This is because they are meant to be used as a tool to help people get started on their weight loss journey, rather than a long-term solution.
It’s important to talk to your doctor about how long you will need to take prescription weight loss pills. Your doctor will monitor your progress and adjust your treatment plan as needed. They may also recommend lifestyle changes, such as diet and exercise, to help you maintain your weight loss over time.

Many manufacturers offer patient assistance programs or discounts for people who are uninsured or underinsured. Your doctor or pharmacist may also be able to recommend alternative medications or provide guidance on how to access prescription weight loss pills at a lower cost.
