grupo_derecho: exámenes y procedimientos

My doctor prescribed a medicine under its generic name, but I don't think it is having the same effect as the medicine under its brand name. I want to take the commercial medicine, but it is not in the POS: can I still ask for it?

It can be ordered only if the doctor prescribes it, as this is one of the requirements for the granting of medicines excluded from the POS. The physician may exceptionally formulate it under a trade name only if it is of better quality, safety, efficacy and convenience. If the generic medicine produces the same effects, it is not necessary to formulate it under the trade name [...].
