Ferogen 20mg 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. Ferogen 20mg Injection is generally given by a doctor or nurse. You should not self-administer this medicine at home. You will be watched carefully to make sure you do not have an allergic reaction. Your doctor will decide how many doses you need depending on the cause of your anemia. It is advisable to eat iron-rich foods like meat, eggs, raisins, broccoli and lentils along with taking Ferogen 20mg Injection. The most common side effects include vomiting, nausea, constipation, and dark-colored stools. Most of these usually go away within a short time. If you are bothered by them or they go on for longer, talk to your doctor or nurse. 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 take advice from 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.
