Adyn-FC Injection is an iron replacement medicine. It is used to treat a type of anemia where you have fewer amount of red blood cells due to insufficient iron in your body (iron-deficiency anemia). Iron is needed to produce the red blood cells that carry oxygen around your body. Adyn-FC Injection is given by injection or infusion (saline drip) into a vein by your doctor or nurse. You will be watched carefully to make sure you do not have an allergic reaction. It is usually given in two doses, seven days apart. Your doctor will decide how much and how often you may need injections to improve your anemia. Eating a well-balanced diet that has enough iron, vitamins, and minerals can help to replenish your iron reserves. Good sources of iron include meat, eggs, raisins, broccoli, and lentils. The most common side effects include vomiting, headache, dizziness, high blood pressure, and pain or irritation at the site of injection. Most of these usually go away within a short time of the injection. 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.
