Hi, I accidentally doubled up on my multivitamin today. I took a total of 2 today, and each contains 18 mg. iron (as ferrous fumarate). I took one this morning at 8 a.m. with breakfast (eggs oatmeal blueberries) and one on accident with lunch at 1:30 (cauliflower chicken and brown rice). I called poison control, and they said I should be alright, except for some mild diarrhea and possibly vomiting. They suggested I drink some milk, so I did. I ve only had to go once, but I m concerned. Do you think there s any reason to worry, or will I survive (LOL). Thank you for putting my mind at ease. =)
