Hi my friend consumed 30herfem tabs containing 100 mg elemental iron per day for 3 days. He had nausea and vomiting. But later he is fine. A week after that he was diagnosed with LFT (Liver Function Test) and serum creatinine everything is normal. This was happened 2 weeks ago. But now he's feeling weak slightly nausea and no hungry. So isn't he safe now. Is he still affected by iron overdose?
