Hello, The injection prescribed for your child is most likely iron injection. Iron injections are sometimes used to treat pica, a condition where individuals eat non-food items such as chalk, mud, etc.While iron injections can be effective in treating iron-deficiency anemia, they do have potential side effects. Some common side effects of iron injections include: - Pain or discomfort at the injection site. - Nausea, vomiting, or diarrhea. - Headache - Dizziness or lightheadedness - Allergic reaction, which can include difficulty breathing, hives, or swelling of the face, lips, tongue, or throat. If your child experiences any of these side effects after an iron injection, you should contact their healthcare provider immediately. In rare cases, iron injections can cause more serious side effects such as infection or anaphylaxis, a severe allergic reaction. Therefore, it is important to discuss the risks and benefits of iron injections with your child s healthcare provider before starting treatment. Take care. Hope I have answered your question.
