I just started on this drug now and I cant find a answer on "if I miss a dose, do I take it as soon as I can or do I take it the next day." I've been trying to get a hold of my phys. but, I can't. I wanted to ask her, if it was okay for me not to change my med. and just to stay on my sertraline, but she would'nt answer me back so, I decided just to try this out. is it ok?
