Does Equetro build up effectiveness slowly or is effective immediately? What is the effect of missing doses?

Are psychiatrists don't even prescribe this anymore, I even think they stopped leaving us samples. I guess it is disappearing. I think the rep said bad marketing. But we still prescribe the generic carbamazepine and if you continue it after for a while it should gain back its effication as long as he stays on it. I will have to let the Psychiatrists I work with know that I heard someone that has been on this. Thanks for sharing your question. Also, how is it working for him?
