How it works: Naltrexone is approved to treat alcohol and opioid dependence. Bupropion is approved to treat depression and seasonal affective disorder and aid in smoking cessation. Together these two drugs block opioid stimulation and suppress appetite.
Who should not take it? Naltrexone/bupropion should not be taken by people who have seizure disorders, women who are pregnant or who are trying to become pregnant, people using opioids, or individuals with eating disorders. Naltrexone/bupropion can also raise blood pressure and heart rate and must not be used by people with uncontrolled high blood pressure.
Brand name: Saxenda
Generic name: Liraglutide
How it works. Liraglutide (Victoza) was initially used with diet and exercise to control blood sugar in people with diabetes. One of the side effects observed was weight loss. As a result, researchers developed a form of Liraglutide (Saxenda) specifically for weight loss. Unlike other weight loss drugs, Liraglutide is given by injection. It slows the emptying of the stomach which decreases appetite and causes weight loss.
Who should not take it? Saxenda should not be used in patients with a personal or family history of medullary thyroid carcinoma (MTC), or in patients taking Victoza for the management of diabetes. Saxenda and Victoza have the same active ingredient, liraglutide, therefore they should not be used together.
As always, speak with your doctor about the best medications for you.
