I've noticed over the years that doctor's don't always tell you all about the drugs they prescribe. I've learned the hard way to look up everything about any medications I've been prescribed. ***MOST DOCTORS ARE THROUGH IN there explanations But not ALL*** When in doubt resource the drugs. And call your doctors . We all need to know what we are putting into our bodies. Most doctors are caring people but there so that I feel get "comps" from the drug companies. I are care about ya'all . Know what your takin.
