Product introduction

N-Sucrose Injection is generally given by a doctor or nurse. It is important to follow your doctor's instructions carefully and attend all scheduled doses to ensure the treatment works effectively. While on treatment, eating a balanced diet that includes iron-rich foods can also support recovery. Do not stop or skip injections without medical advice, even if you start feeling better, as completing the full course helps restore and maintain healthy iron levels.


Some people may experience mild side effects such as pain or swelling at the injection site, nausea, diarrhea, a metallic taste, or dizziness. These effects usually go away on their own, but if they bother you or worsen, let your doctor know. Rarely, allergic reactions like rash, itching, or difficulty breathing may occur. If you notice any serious symptoms after the injection, seek medical help immediately.


Before starting N-Sucrose Injection, inform your doctor if you have a history of allergies, liver disease, or infections, or if you are pregnant or breastfeeding. During treatment, avoid taking other iron supplements unless your doctor tells you to, as too much iron can be harmful. Also, let your doctor know about any other medicines you are taking to prevent possible drug interactions.
