Do you feel tired all the time? Do you feel dizzy when you walk a little faster or climb a flight of stairs? Do you feel that your skin and lips are pale? These can often be symptoms of iron deficiency anemia, which is caused by a decrease in iron levels in the body. Simply put, a lack of blood in our body. Usually, a doctor will first prescribe medicine like iron tablets for this. But for some people, it is difficult to control this condition with tablets alone. At such times, the doctor may recommend an iron injection given into a vein to provide iron to the body quickly and efficiently. Today we are talking about one such powerful iron injection, Ferric Derisomaltose .
What actually happens with this vaccine?
Think of the red blood cells in our bodies as delivery trucks. The main cargo of these trucks is oxygen. These red blood cells carry oxygen from the lungs to cells in every corner of the body. So, iron is an essential element for red blood cells to do this job properly. Without iron, the body cannot make healthy red blood cells that can properly carry oxygen.
Ferric Derisomaltose is a liquid that contains iron. It is given as an injection directly into your vein. This means that the required amount of iron is added directly to the blood faster than the oral tablets are absorbed from the intestines. This helps the body quickly replenish the lost iron, produce new healthy red blood cells, and reduce the symptoms of anemia such as fatigue and weakness.
