i went to get my prescription filled and i think they mixed in some of the wrong pills. normally i get spironolactone 25 mg. they have "5880" on them. mixed in with them was a flat round pill that has "5137" on them. i am on remodulin for pulmonary hypertension . did they really give me the wrong pills? or are they the same just with a different imprint? also what would have happened if i had taken the "5137" pills? thanks
