I mean it takes 17 weeks alone to get to the dose they used in studies (2.4mg), but I have seen an appreciable difference in body weight (10-15%) of body weight) within 3 months of starting it even before we get to that dose. I've been seeing about 20-25% body weight loss in my patients, especially because I'm pretty firm in my recommendations for physical exercise and calorie tracking. I refer to a local nutritionist and will have them start an exercise regimen with a personal trainer.
It's lifechanging for patients. I've gotten several patients off of antidepressants because their self-esteem, social anxiety, and overall physical health parameters of depression (sleep, energy, appetite, concentration) are much better. I wonder if it should be studied as an antidepressant for certain patients because we do know that those other lifestyle factors can have a similar effect size to an SSRI.
It hasn't worked for everyone though as I've had some people not respond at all even at the higher dosages, which is disappointing. You're telling me it takes 72 weeks of continuous intervention makes me feel like I should persist even though it's been about 6-8 months of using it.
