Criteria for Weight Loss Medication Prescriptions
Prescribing weight loss medications requires careful consideration of individual factors, including a patient's medical history, existing health conditions, and lifestyle. A personalized approach is essential to ensure safety and effectiveness, as not all patients may benefit from the same treatment. Medical supervision should accompany any use of these medications to monitor efficacy and manage potential side effects.
Currently Available Weight Loss Medications
- Semaglutide (Wegovy, Ozempic)
- A GLP-1 receptor agonist that mimics incretin hormones, promoting weight loss by reducing appetite and slowing gastric emptying.
- Common side effects include nausea, diarrhea, and constipation.
- Tirzepatide (Zepbound, Mounjaro)
- Also a GLP-1 agonist, it works similarly to semaglutide with comparable efficacy.
- Liraglutide (Saxenda)
- Another GLP-1 agonist noted for its ability to promote significant weight loss over time.
- Phentermine (Adipex, Suprenza)
- A sympathomimetic amine that stimulates the release of norepinephrine and epinephrine, increasing metabolism and reducing appetite.
- Phentermine-topiramate (Qsymia)
- Combines phentermine with topiramate, a carbonic anhydrase inhibitor, to enhance weight loss through appetite suppression and metabolic effects.
- Naltrexone-bupropion (Contrave)
- Naltrexone blocks opioid receptors to reduce nausea associated with bupropion, which enhances energy and reduces appetite.
- Setmelanotide (Imcivree)
- Acts on hypothalamic neurons to regulate food intake, particularly effective in Prader-Willi syndrome.
- Orlistat (Xenical and Alli)
- A lipase inhibitor that prevents fat absorption, reducing overall fat intake and promoting weight loss.
- Hydrogel (Plenity)
- Expands in the stomach to create a feeling of fullness, curbing appetite and aiding in portion control.
Upcoming Weight Loss Medications
Emerging treatments include newer GLP-1 agonists and medications targeting specific metabolic pathways. These may offer additional options for patients who do not respond adequately to current therapies or have unique weight loss needs.

What is the strongest weight loss prescription medication?
The strongest may depend on the patient's specific needs and medical history. GLP-1 agonists are often highlighted for their sustained efficacy.
How do weight loss medications work?
They act through various mechanisms, including appetite suppression, metabolic stimulation, and fat absorption inhibition.
Are there medications that can cause weight gain?
Yes, some drugs like antidepressants may lead to weight gain as a side effect.
How should weight loss medications be used with other treatments?
Combination therapies are often recommended for better results, such as pairing medications with diet, exercise, and behavioral changes.
How long do weight-loss medications need to be taken?
Most are prescribed short-term (3-6 months) to assess efficacy before considering long-term use.
How have options in weight loss medications changed recently?
Newer agents like semaglutide and tirzepatide have expanded treatment options, particularly for obesity related to metabolic disorders.
How do they compare in cost?
Costs vary widely depending on the medication and insurance coverage, influencing prescription choices.
How do they affect weight regain?

OTC vs. prescription: What are the differences?

Conclusion
Weight loss medications offer a range of options for individuals struggling with obesity. While they can be effective, they should be used under medical supervision to ensure safety and appropriateness. A combination of medication, diet, and lifestyle changes is typically recommended for optimal results.
