Hi Nal,
I respectfully disagree, the information about the warning came from the FDA web site. I trust the FDA website.
You stated that it is the same as taking
Phen Pro. Yes, doctors are "allowed" to do this. However in this case the manufacturer recommends against it do to findings in studies. So it isn't the same thing, is it?

In fact here it is again:
WARNING regarding Valvular Irregularities and Primary Pulmonary Hypertension
If you have any heart problems while taking both of these drugs together, please consult your doctor.
