Understanding Prescription Weight-Loss Drugs

Role in Treatment

Prescription weight-loss drugs play a key role in treating obesity, diabetes, and have side effects depending on the milligrams per dose. They are used alongside diet and exercise. These drugs can help people with obesity and diabetes lose significant weight when combined with lifestyle changes, though there may be side effects.

Criteria for Prescription

Doctors prescribe these drugs based on specific criteria. One important factor is Body Mass Index (BMI). Typically, a BMI over 30 qualifies for treatment. If someone has a BMI over 27 with related health issues like diabetes or high blood pressure, they might also qualify for a medical weight management program in their weight loss journey for obesity.

Health Benefits

Losing even 5% to 10% of total body weight due to obesity can lead to big health benefits and fewer costs. People often see lower blood pressure and improved blood sugar levels with weight loss and a medical weight management program. This reduction decreases the risk of serious conditions.

Specific Drugs

There are various prescription drugs available. Naltrexone is one example, often combined with other medications. These drugs come in different forms, including pills and prefilled pens for injections, for people in a medical weight management program, though side effects and costs vary.

Dosage Information

Dosages vary by drug and patient needs. Some drugs may be taken in milligram doses daily. It’s crucial to follow the doctor’s instructions carefully to avoid side effects like vision changes and weight loss, which may affect people.

Eligibility for Weight-Loss Medications

BMI Requirements

To qualify for weight-loss medications, people must meet specific BMI requirements and consider side effects. A BMI greater than 30 typically qualifies someone. If the BMI is greater than 27 and there are obesity-related health issues like diabetes or hypertension, people may also be eligible for weight loss despite potential side effects. These guidelines help ensure that the medication is used appropriately by people, considering side effects and weight loss.

Prior Efforts with Diet and Exercise

Before considering medication, people should have made serious attempts to lose weight through diet and exercise. This step is crucial as lifestyle changes are often the first line of defense in weight loss management for people, minimizing side effects. A medical weight loss clinic usually looks for these efforts and side effects in a patient’s history. Sustainable lifestyle changes can sometimes achieve significant weight loss results for people without medication side effects.

Health History and Challenges

Individual health history plays a vital role in determining eligibility for weight-loss drugs for people due to side effects. Conditions like diabetes, heart disease, weight loss, or other chronic illnesses can influence this decision for people due to side effects. Doctors assess these factors, including side effects and weight loss, to decide if medication is safe and effective for the patient. Personal challenges, such as a history of weight loss regain after losing excess weight, are also considered.

Types of FDA-Approved Weight Loss Drugs


Orlistat blocks fat absorption in the intestine. It reduces the amount of fat absorbed by about 30%, aiding weight loss but with potential side effects. Side effects include stomach pain and oily stools.


Phentermine-Topiramate suppresses appetite and increases feelings of fullness. The combination of these two drugs helps reduce hunger. Common side effects are dry mouth, dizziness, and insomnia.


Naltrexone-Bupropion works on the brain to control hunger and cravings for weight loss but may have side effects. This drug combination targets areas related to reward and pleasure, with side effects including weight loss. Potential side effects include nausea and constipation.


Liraglutide mimics a hormone that regulates appetite. It helps increase feelings of fullness after meals. Some side effects are nausea and diarrhea.


Semaglutide also mimics a natural hormone to regulate appetite. It is taken once a week through an injection. Side effects may include nausea and vomiting.


Setmelanotide is approved for weight loss in individuals aged 6 and older with certain rare genetic conditions. This drug affects hunger signals in the brain. Side effects can include skin darkening and nausea.

Duration and Considerations for Weight-Loss Drug Use

Long-term Use

The duration of weight-loss drug use varies. It depends on the effectiveness and the goal of sustainable weight loss. Some people may need to take these medications long term for weight loss. Others might achieve their goals within months.

Weight Regain

Weight regain can happen after stopping medication. This is common and highlights the need for ongoing lifestyle changes and weight loss. Diet and exercise are crucial for maintaining weight loss. Without these changes, many will regain lost weight.

Side Effects

Weight-loss drugs have potential side effects. Common side effects include nausea, constipation, and headache. More serious side effects might occur, such as increased heart rate, weight loss, or kidney damage. It’s important to monitor any adverse reactions.


The cost of these medications can be high. A month supply of weight loss can be expensive, and not all insurance plans cover them. Out-of-pocket costs could be a barrier for some individuals seeking weight loss treatment.
