I-key 50mg Injection is an iron replacement product. It is used to treat a type of anemia in which the number of red blood cells is less due to a low level of iron in your body (iron-deficiency anemia). Iron is needed to produce the red blood cells that carry oxygen around your body. I-key 50mg Injection is generally given by a doctor or a nurse. You will be watched carefully to make sure you do not have an allergic reaction. The dose and duration will depend on the cause and severity of your anemia. It is advisable to eat iron-rich foods such as meat, eggs, raisins, broccoli and lentils along with taking I-key 50mg Injection. The most common side effects include vomiting, nausea, dark-colored stools, constipation, and diarrhea. Most of these usually go away within a short time. But if you are bothered by them or if the side-effects continue, talk to your doctor. You should not have this medicine if your anemia is not caused by a lack of iron. Before taking it, tell your doctor if you have rheumatoid arthritis, asthma or other allergies, high blood pressure, or liver problems. This may affect your treatment. It is not known whether this medicine is safe for use if you are pregnant or breastfeeding so please consult your doctor. You will have tests to check your blood cells and iron levels, monitor your progress and check for side effects. It may be advisable to limit alcohol during treatment.
