Giving 5 ml of iron syrup instead of 5 drops can sometimes upset a small child?s stomach, but the actual risk depends on the syrup strength, the child?s weight, and how much iron was present in that dose. Some children may not develop any problem, while others can show symptoms several hours later. Iron overdose mainly affects the stomach and intestines first, so observation during the next few hours is important. Watch carefully for vomiting, stomach pain, loose stools, dark stools, unusual crying, poor feeding, weakness, excessive sleepiness, or blood in vomit or stool. Avoid giving another iron dose until the situation is reviewed properly. Keep the syrup bottle nearby, as the doctor may need to know the exact concentration and the amount swallowed. Do not try home remedies or force vomiting, as this may worsen irritation. A doctor should be informed soon, especially if repeated vomiting, breathing changes, unusual drowsiness, or reduced responsiveness appear after the overdose.
