Any psychiatric medication would have it's own way of working in a client's body. Yes, you are correct about the fact that they work different but if you compare it to other medicines we take. For example: pain medication, we can take different medication of the same pain and they all work in giving the results but they are structurally very different. It's the same with psychiatric medication.
Next Steps
You can ask your psychiatrist to explain to you how different medications work as well.
