If I am taking duromine (weight loss pill),is it okay if I still take caltrate plus(calcium supplement)?

Like CarTex said, this is not a simple question to be asking on any Q&A website as we don't know your medical history and what other meds you may be taking here so we could inadvertently give you the wrong advice and you could soon be in a whole world of hurt here.  So this is best discussed with your Physician and/or Pharmacist (as a last resort since they wont have your medical history)  so start with your DR to be absolutely sure as I would hate to see you end up in an ER somewhere.  Good luck
