Imagine that a member of your family, perhaps an elderly grandmother or grandfather, is taking a medicine called 'Digoxin' prescribed by a doctor for a heart condition. It is a very important medicine. But what if, by mistake, due to memory loss with age, or because you forget whether you took the medicine before, you take too much of this medicine? That is a very dangerous, even life-threatening situation. In such an emergency, that is, in the case of Digoxin poisoning (overdose), we are talking about a special treatment that can save lives.
Simply put, what is this Digoxin Immune Fab?
While the name may sound a bit complicated, its function is actually quite simple. Digoxin Immune Fab is an antidote . To be precise, it is a specially designed protein. Its amazing ability is to find and attach to particles of the drug Digoxin (and its close relative Digitoxin) that are in excess in the body.
Think of the excess Digoxin particles in our bodies as little enemies that are causing problems. This Digoxin Immune Fab vaccine is like special commandos sent to neutralize those enemies. When these 'soldiers' enter the body, they go straight to and attach to the excess Digoxin particles. Once they do, Digoxin loses its ability to harm our heart and other parts of the body. After that, this bound complex is excreted from the body through the kidneys in the urine.
Simply put, this is done to remove the Digoxin poison from the body and restore the patient to normal.
Things you need to tell your doctor before giving this treatment
Even though this is an emergency treatment, it is very important to inform the doctor about your (or the patient's) complete health history, as it directly affects the success of the treatment and your safety.
Don't forget to mention these points in particular:
- Kidney disease: If you have any kidney-related conditions, be sure to tell your doctor about them. Because, as we discussed earlier, Digoxin and these antidotes are eliminated from the body through the kidneys. So if your kidneys are not working properly, your doctor may need to change your treatment plan.
- Allergies: This is very important. Have you ever had any allergies to any medications before? In particular, if you have any allergies to Digoxin Immune Fab, sheep proteins , papain, chymopapain (these can sometimes be found in things like papaya), other foods, dyes, or preservatives, be sure to tell your doctor.
- Pregnancy or breastfeeding: It is essential to inform your doctor if you are pregnant, trying to become pregnant, or breastfeeding.
How do you use this medicine?
This is not a medicine you can pick up at a pharmacy and take home. This is a treatment for severe poisoning that is only given in a hospital or clinic, under medical supervision.
- How it is given: It is usually given as an injection into a vein (a vein) or as an infusion (a saline solution). This is done by a doctor or a specially trained nursing staff member.
- For children: If this treatment is given to young children, special care and dosage calculation are required. Therefore, this is done under the advice of a pediatrician.
- Overdosage: Since this treatment is given in case of an overdose of Digoxin, there is usually no need to worry about an overdose of this medicine. However, if it does happen somehow, the hospital staff will take the necessary measures. In general, in case of an overdose of any medicine, we advise you to immediately contact the National Poisons Information Centre at the Colombo National Hospital , or go to the nearest Emergency Treatment Unit (ETU) . Since this treatment is given in the hospital, any problems can be managed on the spot.
