Antidepressant Medications Possibly Linked To Decreased Weight
The U.S. Food and Drug Administration (FDA) has approved a combination medication, Contrave, which contains bupropion and naltrexone, for the treatment of obesity and overweight. This medication is significant as bupropion, a component of Contrave, is consistently connected to weight loss in various studies.
However, it's important to clarify that neither bupropion on its own nor any other antidepressant is FDA-approved as a weight loss medication. While bupropion can lead to weight loss, it is primarily prescribed for treating depression and smoking cessation.
Bupropion's effect on appetite and weight is connected to its role as an NDRI (Norepinephrine-Dopamine Reuptake Inhibitor), influencing neurotransmitters in the brain. This influence can help regulate hunger cravings, leading to weight loss.
Other antidepressants that can potentially cause weight loss include Fluoxetine (Prozac), Duloxetine (Cymbalta), and Sertraline (Zoloft). Fluoxetine, for instance, may lead to short-term weight loss due to transient appetite suppression, typically resulting in 1–3 pounds of weight loss over the first 12 weeks. However, this effect is often temporary and may not persist as treatment continues.
Weight loss associated with these antidepressants occurs due to several mechanisms, including appetite suppression, metabolic changes, and improvement in mood. As depression improves, individuals may experience healthier eating habits or have less emotional eating, which can contribute to weight loss.
It's crucial to remember that these medications should not be used solely for weight loss. They are primarily prescribed for treating depression and anxiety. The weight loss effect is often a secondary benefit for some users.
If you experience unexplained weight loss (5 pounds or more within a week), it may signal an underlying health issue that needs to be assessed. Discuss any sudden or drastic weight changes with your healthcare provider.
Weight loss with any medication is most effective when combined with lifestyle changes like eating a healthier diet and exercising more. Additionally, medication adjustments or changes may be necessary to address weight concerns or issues related to the mental health condition behind the treatment.
Contrave isn't approved to treat depression, but it can help manage weight in conjunction with diet and exercise. The drop in pounds is more pronounced when bupropion is taken in tandem with naltrexone.
In conclusion, while some antidepressants can lead to weight loss, it's essential to remember that they are primarily prescribed for treating depression and anxiety. Always consult with your healthcare provider regarding any changes in your weight or medication regimen.
