Starting Contrave: What to Expect in Month 1
Starting Contrave can feel very different from other weight loss medications. Unlike GLP-1 therapies that primarily affect digestion, Contrave works on the brain’s appetite and reward pathways. This means it helps reduce cravings and emotional eating patterns rather than simply making you feel full.
Because of this, the first month is less about physical fullness and more about behavioral shifts and neurologic adjustment. The changes can feel subtle at first—but they are meaningful.

Feedback from our amazing patients!
"I can’t believe I did not know about this kind of service! This was absolutely perfect for my health concern and they were able to provide me with the necessary medication and with such cinch. Completely recommended this service. For minor health concerns, this can save you an unnecessary and costly trip to an urgent care center."
"Amazing!! Easy and fast! I didn’t have to take my 4 year old into an urgent care where only god knows what germs are there. The doctor sent the script right to my pharmacy within minutes!!!"
"I would give 10 stars if I could! CallonDoc is literally the reason I am recovering instead of suffering as I write this. I was skeptical at first, but I’m not kidding when I tell you I got prescribed my antibiotics and picked it up at the pharmacy within 2 hours. So instead of waiting & paying around 300$...I paid 40$!! I’m very pleased."
