This medication may rarely cause serious low phosphate levels. You may be at increased risk if you have a history of stomach/intestinal problems (such as malabsorption, bowel disease), parathyroid problems, low vitamin D levels, nutrient deficiency (malnutrition), or certain genetic conditions (such as hereditary hemorrhagic telangiectasia-HHT or Osler-Weber-Rendu syndrome). Tell your doctor right away if you have any symptoms of low phosphate such as muscle pain or weakness, bone pain, joint pain, or bone fractures.
This medication is used to treat "iron-poor" blood (iron deficiency anemia). Low iron levels can occur due to many conditions, including when your body cannot get enough iron from food (because of poor nutrition or poor absorption) or when there is long-term blood loss. Ferric carboxymaltose is a form of injectable iron that is used if you cannot take iron by mouth because of side effects or an unsuccessful response to treatment. It is also used by people who have anemia due to long-term kidney disease or heart failure.
Iron is an important mineral that your body needs to make enough healthy red blood cells to carry oxygen throughout your body.
Read the Patient Information Leaflet if available from your pharmacist before you start using ferric carboxymaltose and with each treatment. If you have any questions, ask your doctor or pharmacist.
This medication is given by injection into a vein by a health care professional as directed by your doctor. The dosage is based on your medical condition, weight, lab tests, and response to treatment.
