There are quite a few drugs for depression and anxiety with varied responses that are quite individualized. It is unclear from your post, but I too have the feeling you are talking about a GP prescribing this. I would highly encourage a specialist. They work with these drugs every day and are far better informed to play around and find the one that works for you. And when you find the right one, it can be a real godsend!

And definitely talk to a pharmacist if you are worried about drug interactions or have any general drug questions.
