Reece is suppose to start taking this today. I was reading the info that comes with it & says NOT to take 1 hour before or 2 hours after aluminum or magnesium-containing antacids. My question is does that mean Prevacid? I put in a call to his nurse, but they said she may not call back until tomorrow moring. I figured someone would know on here. Thanks. In the meantime Im gonna look up Prevacid.
