Have you ever felt like you’ve tried everything to lose weight, but nothing works? You’re not alone. Millions of people struggle with their weight. For many, the answer might be in prescription weight loss medications. These FDA-approved drugs can help those who have tried diet and exercise without success.
Before 2012, only a few weight loss medications were approved by the FDA. Phentermine and orlistat were the most common. But, in recent years, new drugs like Wegovy and Ozempic have become popular. These medications make you feel fuller and less hungry, helping you lose weight.
Key Takeaways
- Prescription weight loss medications can be an effective tool for adults who have serious health problems due to their weight and have tried diet and exercise without success.
- The FDA has approved six weight-loss drugs for long-term use, including semaglutide (Wegovy), phentermine-topiramate (Qsymia), and orlistat (Xenical).
- These medications work by suppressing appetite, promoting feelings of fullness, or affecting how the body absorbs fat.
- Weight-loss drugs can lead to an additional 3% to 12% of total body weight lost over a year when combined with lifestyle changes.
- Prescription weight-loss medications may have side effects and may not be covered by insurance, so it’s important to discuss the risks and benefits with your healthcare provider.
Introduction to Weight Loss Drugs
Prescription weight-loss drugs are given by doctors to help you lose weight. They work best when used with a healthy diet and exercise. These drugs are for adults who have serious health problems because of their weight. They have tried to lose weight on their own but haven’t been successful.
Overview of Prescription Weight-Loss Medications
The FDA has approved several weight-loss drugs for long-term use. These include bupropion-naltrexone (Contrave), liraglutide (Saxenda), orlistat (Xenical, Alli), phentermine-topiramate (Qsymia), semaglutide (Wegovy), and setmelanotide (Imcivree). These weight loss drugs work best when used with lifestyle changes for more weight loss.
Benefits of Weight Loss Medication
Studies show that using weight loss medications for a year can lead to more weight loss than just changing your lifestyle. Losing 5% to 10% of your body weight can greatly improve your health. It can lower blood pressure, blood sugar, and triglyceride levels.
But, not many people successfully lose weight and keep it off. Increased physical activity is key for losing weight, especially for those who are overweight. Exercise alone might not lead to much weight loss.
When weight loss medication is used with a low-calorie diet and lifestyle changes, you get better results. The goal is to find a plan that fits your needs and goals.
“Weight regain is less likely when physical activity is part of a weight-reduction regimen.”
Eligibility Criteria for Weight Loss Drugs
If you’re thinking about weight loss medications, knowing the rules is key. Most drugs are for people with a BMI over 30, meaning they’re obese. But, they can also help those with a BMI over 27 and serious health issues like diabetes or high blood pressure.
Body Mass Index (BMI) Guidelines
Your BMI is crucial for getting weight loss drugs. Doctors usually give these drugs if your BMI is:
- Greater than 30 (obesity)
- Greater than 27 with health issues like high blood pressure, diabetes, or high cholesterol
Additional Health Conditions
Health providers look at your overall health too. You might get drugs if you have health problems like:
- High blood pressure
- Diabetes
- High cholesterol
Your doctor will talk about the good and bad of each drug before prescribing it.

“Prescription medications, in conjunction with lifestyle changes, can help individuals lose 3% to 12% more of their initial body weight compared to those solely on a lifestyle program.”
Remember, insurance for weight management drugs varies. Check with your insurance for details. The FDA has approved some drugs for kids and teens, like orlistat and liraglutide.
Always talk to your healthcare provider to see if you’re eligible for weight-loss drugs and what’s best for you.
How Weight Loss Drugs Work
Prescription weight-loss medications help people with obesity or extra weight. They work in different ways to support weight loss. This includes targeting appetite and feelings of fullness.
Appetite Suppression Mechanisms
Drugs like Wegovy and Ozempic mimic hormones that control hunger in the brain. They reduce hunger signals. This means people eat fewer calories and lose weight. For instance, semaglutide (Wegovy) helps people lose about 12% of their body weight on average.
Promoting Feelings of Fullness
Some drugs also make people feel full. They slow down the stomach’s emptying. This makes people feel full longer after eating. It helps cut down on calories, aiding in weight loss with lifestyle changes.
Remember, weight-loss drugs aren’t a quick fix. They work best with healthy eating and regular exercise for lasting weight control.
“About 70% of adults in the U.S. are obese or overweight, making weight loss drugs a significant aspect of healthcare.”
Using weight-loss medications can be part of a bigger plan for managing weight. But, they should be used with a doctor’s advice. It’s important to know how they work, their benefits, and risks before deciding.
FDA-Approved Weight Loss Medications
The U.S. Food and Drug Administration (FDA) has approved several medications to help with weight loss. Semaglutide and tirzepatide are two key FDA-approved weight loss drugs.
Semaglutide (Wegovy, Ozempic)
Semaglutide, known as Wegovy and Ozempic, is a weight loss drug that mimics a hormone called glucagon-like peptide-1 (GLP-1). This hormone affects the brain areas that control hunger, making you feel less hungry and more full. Wegovy is for people with obesity or those who are overweight and have other health problems. Ozempic is for people with type 2 diabetes.
Tirzepatide (Zepbound, Mounjaro)
Tirzepatide, sold as Zepbound and Mounjaro, is a newer weight loss drug approved by the FDA. It works on GLP-1 and GIP receptors, like semaglutide, to reduce hunger and increase feelings of fullness. Zepbound is for adults with a BMI of 30 or higher who need to lose weight. Mounjaro is for treating type 2 diabetes.
In clinical trials, Zepbound at all doses (5 mg, 10 mg, or 15 mg once weekly) showed a significant weight loss after 72 weeks. The highest dose (15 mg once weekly) led to an average weight loss of 18% in non-diabetic adults and 12% in those with type 2 diabetes.
Side effects of Zepbound include nausea, diarrhea, vomiting, constipation, stomach discomfort, and injection site reactions. Fatigue, allergic reactions, burping, hair loss, and acid reflux are also possible. Zepbound is not for people with a history of thyroid cancer or severe stomach problems.
Liraglutide (Saxenda)
Liraglutide, known as Saxenda, is a daily shot that works on gut hormones to signal the brain. It makes you feel full faster and helps reduce hunger. It’s approved for adults with a BMI of 30 or more, or 27 with weight-related health issues. Studies show patients can lose 5-10% of their weight with liraglutide.
Saxenda® (liraglutide) injection 3 mg is for adults with a BMI ≥27 or obesity with a BMI ≥30. It’s also for kids aged 12-17 with a BMI ≥30 and obesity. It should be used with a diet and more exercise.
Side effects of Saxenda® include thyroid tumors, pancreatitis, gallbladder issues, high heart rate, kidney problems, allergic reactions, and depression. It’s not for those with a history of MTC or MEN 2, or serious allergies to liraglutide.
Adults may experience nausea, diarrhea, constipation, vomiting, and injection site reactions. They might also have low blood sugar, headaches, tiredness, dizziness, stomach pain, and changes in blood enzymes. Kids may get fever and stomach issues.
| Key Facts about Saxenda | Details |
|---|---|
| Approved uses |
|
| Mechanism of Action | Acts on hormones from the gut to send signals to the brain, making the patient feel full quicker and decreasing hunger |
| Potential Weight Loss | Clinical studies have shown patients may lose 5-10% of their body weight when taking liraglutide |
| Common Side Effects |
|
| Serious Side Effects |
|
“Saxenda® (liraglutide) injection 3 mg is used for adults with excess weight (BMI ≥27) and obesity (BMI ≥30) to help them lose weight and maintain the weight loss.”
Phentermine and Phentermine Combinations
Phentermine is a well-known weight loss medication. It’s been around for a long time and is often used to help people lose weight. It works by reducing hunger and is usually taken for a short period to start weight loss.
But, phentermine can also be combined with other drugs. For example, it can be paired with topiramate, an anticonvulsant. This combination, known as Qsymia, can make phentermine work even better.
Phentermine and Topiramate (Qsymia)
Qsymia, which combines phentermine and topiramate, is very effective for weight loss. Studies show it can help people lose 5-10% of their body weight. This makes it a good choice for those who are obese or overweight and have weight-related health issues.
But, people with certain health problems should not take Qsymia. These include heart disease, high blood pressure, kidney disease, or liver disease. It should be taken with water, once a day in the morning. Be aware of possible side effects like allergic reactions, vision changes, chest pain, or fast heartbeat.
It’s important to see a healthcare provider regularly while taking this medication. This ensures the medication is used safely and effectively. Monitoring for any negative effects is crucial.
Naltrexone-Bupropion (Contrave)
If you’re having trouble managing your weight, you might know about Contrave. It’s a prescription drug that mixes naltrexone and bupropion. This combo changes how the brain handles pleasure, reducing cravings and hunger.
Contrave is for adults with a BMI of 30 or more, or those with a BMI of 27 and weight-related health issues. Studies show it can help patients lose 5-10% of their weight with diet and exercise.
Contrave targets the brain’s chemical balance that leads to weight gain. Naltrexone and bupropion work together to control the brain’s food response. This makes it easier to avoid overeating and follow a healthy lifestyle.
“Contrave may help adults with a BMI of 30 kg/m2 or greater (obese) or a BMI of 27 kg/m2 or greater (overweight) with weight-related conditions like high blood pressure, high cholesterol, or type 2 diabetes to lose weight.”
But, Contrave has side effects, like seizures, opioid overdose risks, and suicidal thoughts. Common side effects include nausea, constipation, and headaches.
Thinking about naltrexone-bupropion for weight loss? Talk to your doctor first. They can help decide if Contrave is right for you and guide you on safe use.
Setmelanotide (Imcivree)
Finding the right weight loss medication can be tough, but one drug is a standout. Setmelanotide, known as Imcivree, is a special drug. It’s approved by the FDA for treating obesity linked to rare genetic disorders.
Rare Genetic Disorders and Obesity
Setmelanotide works on the melanocortin-4 receptor. It helps reduce hunger and increase feelings of fullness in people with certain genetic conditions. These conditions include POMC deficiency, PCSK1 deficiency, and LEPR deficiency. They can cause severe obesity early in life.
There are only about 150 cases of obesity from these genetic issues in medical records. But for those with them, Imcivree has shown promising results. In one study, 80% of patients with POMC or PCSK1 deficiency lost 10% of their weight. Another study showed 46% of patients with LEPR deficiency had similar weight loss.
Studies over a year showed patients’ hunger levels went down a lot. But how much it changed varied from person to person.
Setmelanotide weight loss medication is a big help for those with rare genetic disorders. But it’s best used with lifestyle changes for lasting results.
Side effects of Imcivree include injection site reactions, skin color changes, headaches, stomach issues, and rarely, depression and suicidal thoughts. It’s important to talk with your doctor about the risks and benefits of this treatment.
Being patient and persistent is key in managing weight. Imcivree might not work for everyone, but it’s a targeted option for those with rare genetic obesity. Understanding this medication can help people make better choices for their weight loss journey.
Orlistat (Xenical, Alli)
If you’re struggling with extra weight, you might know about orlistat. It’s in the weight loss drugs Xenical and Alli. Orlistat doesn’t work on appetite or feeling full. Instead, it stops your body from absorbing fats, helping you lose weight with a low-fat diet.
Blocking Fat Absorption for Weight Management
Orlistat is in Xenical and Alli. It’s a lipase inhibitor. This means it stops your body from breaking down and absorbing fats. So, up to 25% of the fat you eat goes through you without being used by your body. This can help you lose weight over time with a healthy lifestyle.
Alli is the over-the-counter version of orlistat, with a 60-milligram dose. Xenical is the prescription version, with 120 milligrams. Both are approved by the FDA for adults with a BMI of 25 or higher.
| Medication | Dosage | FDA Approval | Average Weight Loss |
|---|---|---|---|
| Alli | 60 mg | Over-the-counter for adults with BMI ≥25 | 5% or more of body weight in 1 year |
| Xenical | 120 mg | Prescription for adults with BMI ≥30 | 5% or more of body weight in 1 year |
Orlistat-based medications can help with weight loss, but remember, it’s part of a bigger plan. Diet, exercise, and regular doctor visits are key for lasting results.
“Alli can help people lose more weight than dieting alone, but it’s not a magic bullet. Combining the medication with a healthy lifestyle is crucial for long-term success.”
Emerging Weight Loss Medications
The need for new weight loss drugs is growing fast. Researchers are looking into new ways to treat future obesity treatments. They focus on hormones and pathways that control appetite and metabolism. This could help people who are overweight find new solutions.
Orofglipron is a new drug being made. It’s an oral GLP-1 inhibitor that helps reduce hunger and makes you feel full. Retatrutide is another one being studied. It works on GLP-1, GIP, and glucagon, which are important for energy balance.
Monoclonal antibodies like bimagrumab could also be a game-changer. They might help build more muscle and burn less fat. This is a new way to tackle obesity.
| Emerging Weight Loss Drug | Mechanism of Action | Potential Benefits |
|---|---|---|
| Orforglipron | Oral GLP-1 inhibitor | Appetite suppression, Increased feelings of fullness |
| Retatrutide | Targets GLP-1, GIP, and Glucagon | Comprehensive regulation of energy balance |
| Bimagrumab | Monoclonal antibody | Increased muscle mass, Decreased fat |
Scientists are working hard to improve weight loss treatments. These new weight loss drugs and future obesity treatments could offer better and more tailored options. They aim to help people manage their weight and boost their health.
popular weight loss drug
Choosing the right weight loss medication is a big decision. Doctors look at many things to pick the best one for each person. They consider the patient’s BMI, health conditions, past medicines, and possible side effects.
Cost and insurance also matter a lot. Drugs like Ozempic and Zepbound are popular for losing weight. But, they can cost up to $1,600 a month without insurance, making them hard for many to get.
- Doctors like Dr. Jorge Rodriguez see more requests for Ozempic, even though it’s mainly for diabetes.
- There are worries about the long-term effects of Ozempic and similar drugs. They’re new, so we’re still learning about their side effects.
- Telehealth companies now offer expensive subscriptions for weight loss services that include Ozempic or similar drugs.
Choosing the right weight loss medication is a team effort between the doctor and the patient. They work together to find a drug that fits the patient’s needs and situation. This way, they make sure the patient’s health is the top priority while figuring out the best way to pick a weight loss medication and what to consider when choosing obesity drugs.
“Individuals who start an Ozempic prescription tend to continue using it to maintain their weight loss, as weight typically returns if the drug is discontinued.”
Side Effects and Precautions
Prescription weight loss drugs come with side effects and precautions. Common side effects include nausea, diarrhea, and stomach pain. You might also feel headaches, dizziness, or get a faster heart rate.
About half of people taking GLP-1 medications face GI side effects. These can be mild and include nausea, bloating, and stomach cramps. Doctors start with a low dose and adjust it to help your body adjust.
It’s key to work closely with your doctor when starting a new weight loss drug. Some people, like pregnant women or those with certain health issues, shouldn’t take these drugs. Doctors check your health history before prescribing to make sure it’s safe for you.
Contraindications and Warnings
Know the risks and warnings of weight loss drugs. For example, people with a family history of thyroid cancer should avoid GLP-1 medications like Ozempic. GLP-1 agonists can also increase the risk of pancreatitis, a serious condition.
Tell your doctor about your health history before starting weight loss drugs. Stopping these drugs can lead to weight gain and worsen conditions like diabetes. Always work with your healthcare team for a safe and effective plan.
Long-Term Weight Management
Keeping weight off can be tough, especially with prescription weight loss drugs. Most people who use these drugs need to keep taking them to stay at a healthy weight. Without lasting changes like eating right and exercising, weight often comes back after stopping the meds.
Maintaining Weight Loss
For lasting weight control, you need a plan that includes both medication and lifestyle changes. Doctors work with patients to create plans that mix medication, healthy eating, and exercise. This approach helps achieve the best results.
Lifestyle Changes for Sustained Results
- Adopt a nutrient-dense, calorie-controlled diet that emphasizes whole, unprocessed foods.
- Engage in regular physical activity, such as brisk walking, swimming, or strength training, for at least 150 minutes per week.
- Prioritize stress management techniques, such as mindfulness, meditation, or yoga, to support overall wellbeing.
- Seek ongoing support from healthcare professionals, family, and friends to maintain motivation and accountability.
Weight loss drugs can really help with weight loss, but they work best with a healthy diet and regular exercise. To keep the weight off, patients need to change their eating and exercise habits for good.
“The key to long-term weight management is not just relying on medication, but making fundamental changes to one’s lifestyle that can be sustained over time.”
Conclusion
Prescription weight loss medications are now a key part of treating obesity and being overweight. The FDA has approved drugs like semaglutide, tirzepatide, and liraglutide. These drugs help by reducing hunger, making you feel full, or stopping fat absorption. When used with lifestyle changes, they can help you lose a lot of weight, which is good for your health.
It’s important for patients to work closely with their doctors to pick the right medication. They need to manage any side effects and keep up with healthy lifestyle changes. It’s also key to teach patients about the risks and benefits of these drugs. Making sure they stick to a healthy diet and exercise plan is also crucial.
In short, FDA-approved weight loss drugs, along with a full approach to managing weight, offer hope for those with obesity and being overweight. By learning about these medications and working with their healthcare team, people can take steps towards a healthier weight.
