Weight Loss Medications for Kids and Adults Explained

On By Dr. Scott RennieIn Weight Loss & Metabolic HealthLeave a comment

As a physician, I know that treating obesity can be tough. Many families put in real effort with diet and exercise and still don’t see enough progress. When that happens, medication becomes worth discussing. Not for everyone. For the right patient, though, it can make a real difference.

Every price below reflects March 2025, when this was first written, and drug pricing in this class moves constantly, list price, cash price, and whatever a given insurer decides to cover can all diverge sharply, so treat every figure below as a historical marker rather than a current quote.

For children ages 12 and older, there are a few choices. Orlistat, brand name Xenical, blocks fat absorption in the gut. Because it stays in the digestive tract, it doesn’t touch appetite or the brain. The catch is side effects. Eat too much fat on this drug and a kid can get oily stools, gas, frequent bowel movements. A low-fat diet helps. It can still be uncomfortable. The price ran about $50 to $200 a month. The FDA cleared it for ages 12 and up.

Liraglutide, brand name Saxenda, is another option. It mimics a gut hormone called GLP-1, helping with appetite control and slowing stomach emptying. It’s effective, and it also helps blood sugar control, which matters if a patient has insulin resistance. But it requires daily injections, and nausea is common. Vomiting and diarrhea can happen too. Monthly cost usually fell between $1,200 and $1,500 a month. The FDA approved it for kids starting at age 12.

Phentermine combined with topiramate, sold as Qsymia, is approved for adolescents 12 and up who meet obesity criteria. Phentermine reduces appetite. Topiramate curbs cravings. Together they can produce substantial weight loss, especially in patients who struggle with binge eating. Side effects include dry mouth, dizziness, insomnia, and mood changes, and blood pressure and heart rate need regular checks. Cost averaged $200 to $300 a month.

Semaglutide, brand name Wegovy, is another GLP-1 receptor agonist, injected once weekly instead of daily. Clinical studies show it produces impressive weight loss. Side effects mirror other GLP-1 drugs: nausea, vomiting, diarrhea, abdominal pain, constipation. Out-of-pocket cost usually ran $1,300 to $1,600 a month. The FDA approved it for adolescents age 12 and up.

Setmelanotide, or Imcivree, is different from everything above. It targets rare genetic conditions that cause obesity, POMC, PCSK1, or LEPR deficiencies, by restoring hormonal signals that regulate hunger. It’s not meant for most patients, only those with a specific genetic diagnosis. For those who qualify, it can work well. The price tag was steep, though: about $16,000 a month.

For adults, the options broaden, and the prices below are again what things cost in March 2025, not today. Phentermine has been used for decades. It works on the central nervous system to suppress appetite, usually prescribed short-term and paired with diet and exercise. It can be effective, but it may cause insomnia, dry mouth, and a faster heart rate, and it isn’t safe for people with heart disease. The cost was low, around $30 to $60 a month.

Bupropion combined with naltrexone, sold as Contrave, takes a different approach. Bupropion affects brain chemistry to help with appetite and mood. Naltrexone reduces cravings. Some patients feel more energetic on it. Side effects can include nausea, dizziness, and insomnia. Mood changes are possible, so follow-up matters. Cost averaged $200 to $300 a month.

Tirzepatide, marketed as Mounjaro, is one of the newest medications. It activates both GLP-1 and GIP receptors, improving satiety and insulin sensitivity. Given as a weekly injection, it has shown striking results for weight loss. Nausea and diarrhea are the most common side effects, as with other drugs in this class. Costs ran high, around $1,000 to $1,500 a month. At publication it was FDA-approved for type 2 diabetes, not obesity, though already used off-label for weight loss.

A few points cut across all of these. Insurance coverage is unpredictable: some insurers won’t cover these drugs at all, others demand proof that lifestyle efforts were tried first. Close monitoring is essential, because side effects vary. None of these drugs replace healthy habits. They work best stacked on top of diet, activity, and behavior change.

For patients and families, the choices can feel like a lot. Knowing what’s actually available, and what each option costs and asks of you, helps match the right treatment to the right person.
