Iron can cause stomach upset, constipation or dark stools. This is harmless. Avoid taking it at the same time as tea, coffee, milk, antacids or calcium, which reduce absorption; separate them by a couple of hours. Drinking through a straw and rinsing the mouth helps limit temporary tooth staining from the liquid. Take only the dose advised. Too much iron is harmful, especially to children. Tell your doctor about other medicines. Store below 30°C. This product information is for general guidance only and does not replace professional medical advice.
