Prescription medications may sometimes be considered as part of a structured weight management plan for people living with obesity or certain health conditions. These are generally evaluated alongside lifestyle approaches such as balanced nutrition, regular physical activity, and healthy sleep habits.
Medications are not a replacement for these lifestyle factors. Instead, they may be part of a comprehensive plan supervised by a qualified healthcare provider.
When Medication May Be Considered
Healthcare providers may discuss prescription weight management medication with adults who meet certain health criteria, such as having a body mass index (BMI) in a higher range along with conditions like type 2 diabetes, high blood pressure, or high cholesterol.
Obesity is influenced by multiple factors – including genetics, environment, diet, and physical activity – and treatment decisions are individualized. Medication is typically only one component of an overall plan.
Types of Prescription Options
In the United States, the FDA has approved several medications for chronic weight management in specific patient populations. These include:
- Bupropion–naltrexone
- Liraglutide
- Orlistat
- Phentermine–topiramate
- Semaglutide
- Setmelanotide
- Tirzepatide (approved more recently for certain adults as part of a calorie-reduced diet and physical activity plan)
These medications are prescribed only after a medical assessment and ongoing monitoring.
In addition, an oral, non-systemic product called Plenity is FDA-approved as a device intended to help with feelings of fullness when used alongside diet and exercise.
Supplements and Non-Prescription Products
Some over-the-counter supplements claim to support weight loss. However, scientific evidence for many is limited, and safety is not always guaranteed. Before taking any supplement, it’s important to speak with a healthcare professional, as some products can interact with other medications or have unwanted effects.
For Children and Teens
Some prescription medications are FDA-approved for use in adolescents aged 12 and older under medical supervision. A few are approved for children as young as 6 with specific rare genetic conditions. Decisions about pediatric use are always made by a specialist.
Role of Healthy Habits
Even when medications are prescribed, healthy eating, physical activity, and adequate rest remain essential. Canadian guidelines generally recommend at least 150 minutes of moderate-intensity aerobic activity per week, plus strength training on two or more days.
Lifestyle changes help support any progress achieved with medication and are key to long-term health.
Setting Goals
Treatment goals are individualized. Healthcare providers may reassess the plan if progress is not seen within a certain timeframe. In some cases, medication use is short-term; in others, it may be longer, depending on a patient’s needs and the advice of their provider.
The Bottom Line
Prescription medications for weight management can be one tool in a broader plan that includes nutrition, exercise, and other lifestyle strategies. They are not suitable for everyone and must be prescribed and monitored by a healthcare professional.
If you’re considering this option, start by having a comprehensive health assessment to determine what’s right for you.
